EARTH SCIENCE 5 Main Factors that make a planet habitable Temperature Water Energy Atmosphere Nutrients Big Bang Theory - most powerful, well-supported theory as to the origins of the universe. ______________________________________________ Georges Lemaître, first suggested the idea of big The first and might be the most important bang theory in the 1920s. condition is the existence of water. The presence of water allowed the first photosynthetic organisms ______________________________________________ to thrive. The Earth is the only known habitable planet Organism such as CYANOBACTERIA used sunlight, in the Solar System. carbon dioxide and water to produce biomass and 1. Capable of being lived in oxygen, an essential component of the atmosphere. These single celled organisms would then evolve 2. Suitable for habitation into the organism present today ______________________________________________ Scientists believe that WATER on Earth came from two possible sources: water released through 1 second VOLCANISM and water from the ICY METEORS of The temperature in the vicinity of the big bang was the outer regions of the Solar System which around 5.5 billion degrees Celsius (10 billion bombarded Earth. Fahrenheit) within the first second. However, at this It is also important to note the Earth’s distance from stage there would have been nothing to see. NASA the sun called HABITABLE ZONE, allows water in its states that "the free electrons would have caused liquid form. It is a torus-shaped region in the Solar light (photons) to scatter in the same manner as System, located roughly between the orbits of the sunlight scatters from cloud-based water droplets. “ planets Jupiter and Mars, that is occupied by a 3 seconds great many solid, irregularly shaped bodies, of many sizes but much smaller than planets, called Protons, electrons, and neutrons—all the subatomic asteroids or minor planets. particles required for atoms and molecules—were present in the first explosion. It is at this stage that HEAT comes from EARTH and from the SUN. lithium, helium, and hydrogen form as the first Heat coming from the Earth is caused by the fundamental elements. radioactive materials decay inside Earth’s core and 380,000 years. mantle and extruded via active tectonics activities such as volcanism and plate movements. Light enters the universe for the first time. The cosmic microwave background is the term used to Heat is also provided by the sun. As radiation from describe this radiation, or light. It is a distinctive the Sun enters Earth, some of the heat is trapped by mark of the Big Bang that Ralph Alpher first the atmosphere. This causes the greenhouse hypothesized to exist in 1948. The age of the cosmos phenomenon needed by plants to carry on with can be inferred from the microwave background that photosynthesis. is still visible today. Photosynthesis also ensures the right amount and 300,000,000 years flow of gases on Earth. Without it, there would be too much greenhouse gases that would cause global This is a bit of a jump ahead. Gravity begins to play a warming. Having a right distance from the sun, life role when the first burst of atoms and gas expands. seems limited to a temperature range of -15 ᴼC to Stars are created in pockets of gas with varying 115 ᴼC. densities, and star clusters eventually give rise to galaxies. This result in changes in weather, ecology and daytime called season. The moon makes Earth a 9,000,000,000 years more livable planet by moderating our home planet's Our sun is formed. Our sun is about 4.6 billion years wobble on its axis, leading to a relatively stable old, while the universe is nearly 14 billion years old. climate. Earth is the third planet from the sun and considered as haven for many life forms. It serves as harbor of life for billions of years and still continue to comfort innumerable life forms.

If one is lost the others will be oceanic = beneath the oceans affected. continental = continents and landforms - known and unknown creatures on land, composed of oxygen, silicon, aluminum, iron, water, and air calcium, sodium, potassium, magnesium - all life on Earth The processes that move matter and energy from PHYSICAL PROPERTIES OF MINERALS one sphere to another is called as sphere interactions. Changes in any sphere greatly affect CRYSTALLINE STRUCTURE OR HABIT the other spheres as well since all the spheres are - overall shape or growth pattern of the mineral. interconnected system. a. Equant – three dimensions of the mineral have The four subsystems are closely linked through the about the same length, like that of a cube or sphere. BIOGEOCHEMICAL CYCLES which involves (ei. garnet) biological, geochemical, and chemical factors. b. Elongate – forms prismatic or prism-like crystals These cycles are alleyways by which substances that are thicker than the needle as in a pencil.

Platy – looks like a flattened and thin crystal (like plate). (ei. Wulfenite) MINERALS LUSTER the building blocks of rocks. - appearance of a mineral when light is reflected present everywhere and some examples can be from its surface. It can be described as opaque, found at home. transparent, dull, or shiny. MINERALOGISTS ✓Metallic luster is opaque and very reflective like gold and silver. use the criteria to determine whether a mineral is classified as mineral or not. ✓Nonmetallic luster is dull, silky, greasy, and pearly like silicates. Example of these are: CLEAVAGE Hematite (hinges, handles, make-up color) - tendency of minerals to break along very smooth, Chromite (chrome plating, dyes) flat and shiny surfaces. Copper (electric wiring) Biotite and mica have one direction, orthoclase has two directions, galena has three directions and fluorite has Quartz (clocks, mirrors) four directions. Gold (jewelries), FRACTURE Feldspar (porcelain, ceramics) – A mineral may break along random, irregular Fluoride (toothpaste) surfaces. It can be classified as conchoidal, uneven, hackly, splintery, and earthy. CHARACTERISTICS OF MINERALS Some minerals break only by fracturing, while others NATURAL OCCURRING both cleave and fracture. – term which identifies mineral as part of Earth’s Quartz has a conchoidal fracture while asbestos has a natural process. splintery fracture. INORGANIC HARDNESS – a substance is not a product of an organism. - measure of the mineral’s resistance to scratching. Harder minerals will scratch softer minerals. HOMOGENEOUS SOLID – minerals should have definite volume and rigid shape. FRIEDRICH MOHS in 1812 ranked minerals according to hardness, He selected ten minerals of DEFINITE CHEMICAL COMPOSITION distinctly different hardness that ranged from a very – represented by chemical formula. soft mineral (talc) to a very hard mineral (diamond). ORDERLY CRYSTALLINE STRUCTURE – atoms of minerals arranged in an orderly and repeating pattern. The scale is named for its creator, the German ADDITIONAL PROPERTIES: geologist and mineralogist Friedrich Mohs. ▪ MAGNETISM - Some minerals are attracted to a hand magnet. To test a mineral for magnetism, just put the magnet and mineral together and see if they are attracted. Magnetite is the only common mineral that is always strongly magnetic. ▪ STRIATIONS - presence of very thin, parallel grooves. The grooves are present in only one of the two sets of cleavages and are best seen with a hand lens. They may not be visible on all parts of a cleavage surface. ▪ SPECIFIC GRAVITY - is the weight of that mineral COLOR divided by the weight of an equal volume of water. The specific gravity of water equals 1.0. - most obvious properties of a mineral but not reliable alone. ▪ Most silicate, or rock-forming, minerals have specific gravities of 2.6 to 3.4; the ore minerals are Quartz varies widely in color, due to minor (parts per usually heavier, with specific gravities of 5 to 8. billion) impurities and even defects in its crystalline structure. ▪ TASTE, ODOR, FEEL – Some minerals have distinctive taste (halite is salt, and tastes like it). STREAK Some give off a distinctive odor (the powder of some - color of the mineral in its powdered form, which sulfide minerals, such as sphalerite, a zinc sulfide, may or may not be the same color as the mineral. smells like rotten eggs), and some have a distinctive feel (talc feels slippery). Streak is a more reliable property than color as streak shows the true color of minerals. It does not CHEMICAL PROPERTIES vary even if color does. EFFERVESCENCE DIAPHANEITY/AMOUNT OF TRANSPARENCY 1) Calcite reacts with HCl; bubbles of CO2 – ability to allow light to pass through it. This is affected by chemical makeup of the mineral sample. OXIDATION TENACITY 1) Reaction between Iron (Fe) and oxygen (O2). - describes the minerals reaction to stress. a. Iron (Fe) + oxygen = Rust a. Brittleness- a mineral turns into powder. (Halite, Metal is weakened by change calcite, fluorite) 2) Reaction between copper and air; creates a b. Malleability - a mineral can be flattened by greenish coating pounding with a hammer. (Silver, copper, gold) a) Copper (Cu) + oxygen = copper oxide c. Ductility- A mineral can be stretched into wire. Metallic sulfide minerals form into sulfuric acid (Gold) when exposed to air and water. Uranium and d. Flexible but inelastic-Minerals are bent but they thorium containing minerals like Autunite (hydrated remain in the new position. (Gold) calcium uranium phosphate) and Thorianite (thorium dioxide) are radioactive. Metals like e.

Mining Mineral processing - process of mineral extraction from a rock seam or the process of extracting minerals from the ore, ore –a natural rock or sediment containing one or refining them, and preparing these minerals for use. more valuable mineral. The minerals can range from The primary steps involved in processing precious metals and iron to gemstones and quartz. minerals include: Modern mining technology uses geophysical Sampling techniques that involve measuring the magnetic, gravity and sonic responses of rocks above and the removal of a portion which represents a whole around a prospective mineral ore body. needed for the analysis of this material. There are two methods of mining: Analysis Surface Mining important to evaluate the valuable component in an ore. This includes chemical, mineral and particle to extract ore minerals near the surface of the earth. size analysis. The soil and rocks that covered the ores are removed through blasting. Comminution Blasting - controlled use of explosives and gas the valuable components of the ore are separated exposure to break rocks. through crushing and grinding. This process begins by crushing the ores to a particular size and finishes Some examples of surface mining are: it by grinding the ores into a powder form. Open-pit mining Concentration most common type of surface mining. the separation of the valuable minerals from the raw Open pit means a big hole (or pit) in the ground. materials. The pit in mine is created by blasting with explosives and drilling. Dewatering It is used to mine gravel and sand and even rock. uses the concentration to convert it to usable Strip mining minerals. This involves filtration and sedimentation of the suspension and drying of the solid materials involves the removal of a thin strip of overburden harvested from this suspension.
