Geology
The scientific study of the Earth, its materials, processes, and history.
Plate Tectonics
A unifying theory in geology that explains the movement of the Earth's lithosphere divided into tectonic plates.
Lithosphere
The outermost layer of the Earth, including the crust and upper mantle.
Crust
The chemically distinct outer layer of the lithosphere, composed of various rocks and minerals.
Mantle
The layer located above the core, containing semi-molten rock (magma) that flows slowly.
Asthenosphere
The upper part of the mantle, composed of semi-molten rock that allows for tectonic plate movement.
Core
The innermost zone of the Earth, consisting of a liquid outer core and a solid inner core, primarily made of iron and nickel.
Continental Drift
The hypothesis proposing that continents were once part of a supercontinent called Pangaea.
Sea-Floor Spreading
The process where new oceanic crust forms at mid-ocean ridges and is pushed away from the ridge.
Fossil Distribution
The occurrence of similar fossils on widely separated continents, indicating they were once connected.
Chemical Weathering
The process involving chemical reactions that alter the minerals within rocks.
Biological Weathering
The process occurring when living organisms contribute to the breakdown of rocks.
Soil Horizons
Layers in soil, including O Horizon, A Horizon, E Horizon, B Horizon, C Horizon, and R Horizon.
Cation Exchange Capacity (CEC)
The soil's ability to retain and supply cations (nutrient ions) to plants.
Base Saturation
The proportion of CEC occupied by nutrient cations, indicating soil fertility.
Rock Cycle
The continuous process of rock formation, alteration, and destruction involving igneous, sedimentary, and metamorphic rocks.
Earthquake
A sudden release of energy in the Earth's crust, causing vibrations.
Volcano
A geological structure formed when molten rock (magma) rises to the Earth's surface.
Weathering
The process through which rocks are broken down by physical, chemical, or biological processes.
Soil
A dynamic natural body of the Earth's surface that supports plant life.
Pedology
The study of soil formation, classification, and mapping.
