Study Notes
Key Concepts in Earth Science
-
Cycle: A sequence of events that recur in the same order, essential for understanding various Earth systems.
-
Luster: A mineral's ability to reflect light, an important characteristic for identifying minerals.
-
Subsystem: A self-contained system operating within a larger system, crucial in ecological and geological contexts.
Atmospheric and Astronomical Insights
-
Atmosphere: Consists of layers of gases surrounding a planet, vital for sustaining life.
-
Astronomy: The branch of science dedicated to studying the universe's origins and evolution.
-
Georges Lemaître: Recognized as the "Father of the Big Bang Theory", which addresses the universe's inception.
-
Big Bang: A theory developed by Lemaître that explains the origin of the universe.
Cosmological and Geological Features
-
Mbombo/Bumba: A deity who experienced severe stomach pain, reflecting mythological concepts of creation.
-
Stratosphere: The atmospheric layer containing the majority of the Earth's ozone, protecting against UV radiation.
-
Hydrological Cycle: The continuous movement of water through the Earth and atmosphere, crucial for climate and ecosystem function.
-
Evaporation: A key process in the water cycle that converts liquid water into vapor.
Age and Composition of the Universe
-
Age of the Universe: Estimated to be approximately 13.8 billion years, providing context for cosmic events and formations.
-
Hardness: Refers to the scratch resistance of minerals, an important factor in mineral identification.
Stages of the Big Bang
-
Stages of the Big Bang:
- Singularity
- Big Bang
- Inflation
- Big Bang Nucleosynthesis
- Recombination
Crust Composition and Planet Types
-
Geosphere: Encompasses the rocks and minerals making up Earth, fundamental to understanding geological processes.
-
Continental Crust: Comprises dry land, primarily composed of granite, and is less dense than oceanic crust.
-
Oceanic Crust: Forms the ocean floor, consists mainly of basalt, and is thinner than continental crust.
-
Planet Categories:
- Terrestrial Planets: Rocky, solid planets.
- Jovian Planets: Gas giants with thick atmospheres.
Earth's Subsystems
-
Biosphere: Includes all living and non-living entities on Earth, highlighting the importance of ecological interconnections.
-
Streak: The color of a mineral in powdered form, another key identification characteristic.
-
Earth's Subsystems:
- Geosphere
- Atmosphere
