What’s New What’s New Activity 2 Rock Cycle Objectives: Identify and describe the processes involved in rock cycle. Procedure: 1.Study the diagram. 2.Answer the questions below on a separate sheet of paper. Question: What are the processes involved rock cycle? Discuss each process. What Is It Earth Materials and Processes: Minerals and Rocks Minerals and Rocks Minerals and rocks are the significant building blocks of our dynamic Earth. They make up the solid part of the lithosphere and provide us with valuable resources. There are over 5,000 minerals but only a few occur as rock-forming minerals. Rocks are classified according to their origin of the formation. Overtime, rocks are gradually transformed from one type to another in what we call Rock Cycle. The origin of any rock is determined by careful examination of its texture, composition, and internal structure. This is the basis of rock identification and classification. Properties of Rocks 1.Rocks exhibit different properties. As to color, rocks may be dark, light, reddish, gray, brown, yellow or even black. 2.Rocks differ in textrure: some are fine, others are rough. 3. Some are glossy in appearance and smooth to touch. 4. Most rocks are hard others are brittle. Figure 1 https://www.storyboardthat.com/storyboards/oliversmith/the-rock-cycle The rock cycle summarizes the transformational processes that change rocks from one kind to another. It shows the entire journey of rocks formed as they changed. As magma cools and solidifies either deep in the Earth’s crust or at the surface, igneous rocks are formed. When the rocks are exposed, they are subjected to weathering and erosion. The weathered and eroded materials form sediments which are transported and deposited by agents of weathering and erosion such as water and wind. Loose sediments accumulate, compacted, and cemented and form sedimentary rock in the process called lithification. Sedimentary or igneous rocks may be subjected to further heating and more pressure; thus, they undergo further alteration in the process called metamorphism. The transformed rocks are known as metamorphic rocks. With high temperature alternating with cold temperature, metamorphic rocks are melted producing molten rock or magma. The cycle begins again, and the same processes take place. Types of Rocks According to geologists, rocks form in different ways. All rocks can be put into one of those fundamental categories based on their origin. The differences between them have to do with how they are formed. Igneous Rock got its name from a Latin word “ignis” which means fire. The parent material of igneous rock is usually magma, a molten material from deep within the Earth that cools and harden. These rocks are hard and tough. Table 1.1. Some examples of Igneous Rocks and its description. Granite a very hard, granular, crystalline, igneous rock consisting mainly of quartz, mica, and feldspar and often used as a building stone. Pumice a very light and porous volcanic rock formed when a gas-rich froth of glassy lava solidifies rapidly. Obsidian a hard, dark, glasslike volcanic rock formed by the rapid solidification of lava without crystallization. Metamorphic rocks have been changed from heat and high pressure. These rocks got their name from “meta” (change) and “morph” (form). Earth movements can cause rocks to be pressed, bent, or deeply buried under layers of other rocks due to an increase in temperature and pressure. These conditions cause physical and chemical changes in the original rock- prolith. The old rocks are forcefully into new kind in the process known as metamorphism. Table 1.2. Some examples of Metamorphic Rocks and its description. Marble a hard-crystalline metamorphic form of limestone, typically white with mottling or streaks of color, that can take a polish and is used in sculpture and architecture. Gneiss a metamorphic rock with a banded or foliated structure, typically coarse-grained and consisting mainly of feldspar, quartz, and mica. Quartzite an extremely compact, hard, granular rock consisting essentially of quartz. It often occurs as silicified sandstone, as in sarsen stones. Sedimentary rock When igneous rocks are exposed at the surface, they begin to wear away. They are altered either by physical or chemical weathering processes. Heat from the sun break rock apart. Rainwater may fill cracks in rocks and eventually break them down. Sedimentary rocks are formed from lithification a process of cementing soft, unconsolidated sediments into hard rocks. Three Main Types of Sedimentary Rocks 1.Clastic sedimentary rocks are derived from mechanical weathering which involves the breakdown of rocks into smaller ones at the surface of the crust, accumulate as clasts, piled on top of one another and lithified. 2. Chemical sedimentary rocks form when dissolved materials precipitate. Precipitation is the process of separating a solid substance from liquid. 3. Organic sedimentary rocks are formed by the accumulated sedimentary debris caused by organic processes. These are rocks that may contain fossils of plants and animals trapped in the sediments as the rock was formed. Table 1.3. Some examples of Sedimentary Rocks and its description. Conglomerate a rock made up of pebbles, pieces of gravel cemented together. Sandstones are sedimentary rock consisting of sand or quartz grains cemented together, typically red, yellow, or brown in color. Coal a combustible black or dark brown rock consisting mainly of carbonized plant matter, found mainly in underground deposits, and widely used as fuel. Minerals Mineralogy is the study of minerals. Minerals are the building blocks of rocks. It is defined as naturally formed, generally inorganic, crystalline solid composed of an ordered array of atoms and having a specific chemical composition. Minerals of the same kind have the same crystal shape. The crystal shape is an external expression of the mineral’s atomic structure. The minerals that make up rocks are called rock- forming minerals. Minerals therefore can be described as: Inorganic-formed by natural geologic process Formed in nature Solids- crystalline substance that are solid at temperature at Earth’s surface Atoms have the same crustalline pattern and with specific chemical composition. Crystalline atoms are arranged in an orderly repetitive manner. Can be represented by a chemical formula Physical Properties of Minerals Luster-refers to the way light is reflected from a mineral surface Hardness-refers to the minerals resistance to being scratched. Streak- along thin line or mark of a different substance or color from its surroundings Cleavage- is the tendency of minerals to break along planes of weak bonding. Fracture- minerals that do not exhibit cleavage are said to fracture when broken. Color- some are of the same color like azurite is always deep blue, sulfur is yellow. Specific gravity- is a number which represents the ratio to the weight of an equal volume of water. Crystal form-external features of a mineral reflect its orderly internal arrangements of atoms. Chemical Properties of Minerals 1.It has distinctly salty taste. 2.Effervesce in hydrochloric acid. 3. Giving off bubbles of carbon dioxide gas. Moh’s Scale of Hardness One of the most important tests for identifying mineral specimens is the Mohs Hardness Test. This test compares the resistance of a mineral to being scratched by ten reference minerals known as the Mohs Hardness Scale. The test is useful because most specimens of a given mineral are very close to the same hardness. This makes hardness a reliable diagnostic property for most minerals. Friedrich Mohs, a German mineralogist, developed the scale in 1812. He selected ten minerals of distinctly different hardness that ranged from a very soft mineral (talc) to a very hard mineral (diamond). Except for diamond, the minerals are all relatively common and easy or inexpensive to obtain. Mohs Hardness Scale Mineral Hardness Mineral Hardness Talc 1 Orthoclase 6 Gypsum 2 Quartz 7 Calcite 3 Topaz 8 Fluorite 4 Corundum 9 Apatite 5 Diamond 10 Metallic Minerals Metallic minerals are the minerals that contain one or more metals. In general, they occur as mineral deposits and are a good conductor of heat and electricity, e.g. iron, copper, gold, bauxite, manganese etc. They are malleable and ductile in nature so they can be easily pounded into thin sheets or stretched into wires to make new products. They are generally found in igneous rocks that are formed by cooling and solidification of lava or magma. They are hard and have a shiny surface, so some of them can be used as gems in jewelry. They are also used in various industries for different purposes, e.g. silicon, which is obtained from quartz, is extensively used in the computer industry; aluminum which is obtained from bauxite is used in automobile and bottling industry. Nonmetallic Minerals Non-metallic minerals are the minerals that do not contain metals, e.g. limestone, mica, coal, gypsum, dolomite, phosphate, salt, manganese, granite etc. They are used in various industries to produce a variety of products, e.g. mica is used in electrical industry, limestone is used in cement industry. Furthermore, they are also used in the production of fertilizers and manufacturing of refractories. They are generally found in sedimentary rocks that are formed by the aggregation of various materials like minerals, remains of organisms, rock particles etc. Earth Materials and Processes: Exogenic Processes Exogenic Process Exogenic processes are processes that take place at or near the Earth’s surface that makes the surface wear away. It is very destructive; they are responsible for degradation and sculpting the Earth’s surface. Weathering Weathering refers to the changes occuring at or near the surface of the Earth which includes disintegration and decomposition. Disintegration is a mechanical process that breaks large masses of rocks into small fragments while decomposition is a chemical process which results in the formation of new substances such as from elements to rocks. Below is the comparison between mechanical and chemical weathering. TYPES OF WEATHERING MECHANICAL/ PHYSICAL CHEMICAL Cause rocks to break into small pieces Occurs when the internal structure of minerals with each piece retaining the is changed by the removal or addition of characteristics of the original elements Process that can cause physical weathering Thermal and Pressure Change Rocks crumble and break into fragments because they are subjected to alternating hot and cold temperatures in many times. Wind and Waves Wind and Waves can cause all physical weathering. Tiny grains of sand are picked up and carried off by the wind which are then blasted on the surface of rocks, smoothening them. Freeze and Thaw If you put a glass in the freezer it will soon break. This is because water expands when it freezes. Similarly, when water collects in the rock pores and slits, it expands when it freezes. Organic Activity Animals and plants also take a heavy toll on rocks and cause them to wear away. For example, there are animals that dig holes on the ground and exposed rocks. Processes that bring about chemical weathering 1.Hydration/hydrolysis Water is nature’s versatile tool that can bring about chemical weathering. There are other chemical compounds in water that become the main agents of chemical weathering. Molecules of some substance in rocks chemically combine with water molecules. This process is called hydration. 2.Carbonation Carbon dioxide may bond with other substances in a process known as carbonation. Rainwater is naturally acidic because CO2 gas from the atmosphere chemically reacts with it and produces carbonic acid, a weak acid that reacts slowly with carbonate minerals in rocks. 3.Oxidation This is another kind of chemical weathering process. This occurs when oxygen combines with another substance like minerals in rocks yielding compounds called oxides. Erosion Erosion involves the movement of the weathered rock. Loosened rock and mineral debris produced by weathering are eroded and transported to a new location by means of air, wind, water, and gravity. Erosion could result to denudation. The lowering surface of the land mass from which the material was removed called denudation. Causes of Erosion 1.Kaingin Method. Trees are cut and burned.Soil losses its fertility. 2. Logging-practice of illegal logging disturbs the soil. 3.Infrastructure projects such as dams, roads, bridges, irrigations and drainage basins, resorts and hydroelectric plant. 4.Mining-companies loosen and dig rocks exposing them to further erosion. 5.Burning grasslands which may lead to accidental fires can destroy plants and leave the soil bare. Effects of Erosion 1.Loss of fertile land 2.Led to increased pollution and sedimentation in streams and rivers Mass Movement (Mass Wasting) Mass wasting, also known as slope movement or mass movement, is the geomorphic process by which soil, sand, regolith, and rock move downslope typically as a solid, continuous or discontinuous mass, largely under the force of gravity, frequently with characteristics of a flow as in debris flows and mudflows. It is the movement of rock and soil down slope under the influence of gravity. Rock falls, slumps, and debris flows are all examples of mass wasting. Often lubricated by rainfall or agitated by seismic activity, these events may occur very rapidly and move as a flow.

It shows the entire journey of rocks formed as they changed. As magma cools and solidifies either deep in the Earth’s crust or at the surface, igneous rocks are formed. When the rocks are exposed, they are subjected to weathering and erosion. The weathered and eroded materials form sediments which are transported and deposited by agents of weathering and erosion such as water and wind. Loose sediments accumulate, compacted, and cemented and form sedimentary rock in the process called lithification. Sedimentary or igneous rocks may be subjected to further heating and more pressure; thus, they undergo further alteration in the process called metamorphism. The transformed rocks are known as metamorphic rocks. With high temperature alternating with cold temperature, metamorphic rocks are melted producing molten rock or magma. The cycle begins again, and the same processes take place. What’s In ( Rocks and Minerals) What I Have Learned What’s more 1. Rock Weathering 2. Rock-forming Mass wasting Rocks minerals Erosion 3.
