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.
