Study Notes

Origin of the Universe and Time, Energy, and Matter

Astronomy is the scientific study of celestial objects beyond Earth's atmosphere including stars, planets, comets, and galaxies.
Cosmology is a subfield of astronomy focusing on the origin and the evolution of the universe.
The Big Bang theory proposes that time began approximately 13.8 billion years ago, marking the universe's origin.
Before the Big Bang, conventional notions of time and space did not exist.
Initially, the universe was in a hot and dense state with energy concentrated in a singularity, characterized by infinite density and temperature.

Cosmic Timeline

The Big Bang Theory outlines the sequence of events from the initial singularity to the present universe.
A closed system (like Earth) only exchanges heat, receiving energy from the Sun and returning energy to space.

Earth Systems and Layers

The geosphere refers to Earth's solid components:
- Crust
- Upper Mantle
- Mantle
- Outer Core
- Inner Core
The biosphere is the zone where life exists on Earth.

Rocks and Minerals

Minerals are naturally occurring, inorganic compounds usually found in crystalline form.
Mineralogy studies the formation, occurrence, and properties of minerals.
Minerals can crystallize from magma or precipitate from solutions:
- Crystallization: Solidification of liquid magma or lava.
- Precipitation: Dissolved minerals forming solids from water.

Properties of Minerals

Streak: The color of a mineral in powdered form, tested on porcelain.
Density: Calculated as mass divided by volume of the mineral.
Crystal Shape: Characteristic shape of crystals or combinations of crystals.
Tenacity: The toughness of a mineral against breaking or deforming.
Hardness: Resistance to abrasion or scratching.
Cleavage: The way minerals split along specific planes.

Types of Minerals

Silicates: Rock-forming minerals containing oxygen and silicon, including:
- Feldspar (50% of Earth’s crust)
- Quartz (composed of silicon and oxygen)
Non-silicates: Less abundant, including minerals like oxides, carbonates, sulfates, and halides.

Geological Processes

Exogenic Processes: External Earth processes, involving the atmosphere, hydrosphere, and biosphere.
Endogenic Processes: Internal Earth processes that drive geological phenomena.

Types of Rocks

Igneous Rocks: Form from crystallized magma/lava; can be either extrusive (volcanic) or intrusive (plutonic).
Sedimentary Rocks: Created from compacted sediments; formed through deposition and cementation.
Metamorphic Rocks: Originated from existing rocks altered by heat, pressure, or mineral exchange, including processes of metamorphism.

Weathering Processes

Mechanical Weathering: Breaks down rocks into smaller pieces without altering their chemical composition.
Chemical Weathering: Involves the chemical decomposition of rocks.
Magma: A hot, viscous mixture of molten and semi-molten rock beneath the Earth's surface.

Principles of Stratigraphy

Principle of Superposition: In an undisturbed layer of stratified rocks, each layer is older than the one above it.
Principle of Original Horizontality: Sediments are deposited horizontally due to gravity.
Principle of Lateral Continuity: Sedimentary rocks spread continuously over large areas until interrupted by barriers or erosion.

Dating Techniques

Relative Dating: Sequencing geological events based on the arrangement of sedimentary rocks.
Absolute Dating: Determining the actual age of rocks and fossils for better chronological understanding.
