What is wind?
100
Break down of rocks without altering their chemical make-up.
What is physical weathering?
100
Occurs only when only bare rock and soil exists.
What is primary succession?
100
The center of the Earth.
What is the inner core?
100
Caused when an earthquake of a 7.5 magnitude or above occurs under the ocean or when a volcano erupts.
What is a tsunami?
200
Sand dunes and arch formations
What is Eolian Landforms or landforms created by wind?
200
Most common form of physical weathering.
What is ice?
200
Occurs after a destructive event leaves some plants behind.
What is secondary succession?
200
Causes the movement of plates.
What is convection currents?
200
Occurs when two plates snap into a new position.
What is an earthquake?
300
Sheet of ice that covers a large area of a continent.
What is a continental glacier?
300
Breaking down of rocks that changes the rock chemically.
What is chemical weathering?
300
Describes the cycle of what animals and plants consume what.
What is the food cycle (food web acceptable)?
300
Plate boundary where two plates are moving apart.
What is a divergent plate boundary?
300
Causes lava flows.
What is a volcanic eruption?
400
Creates flood plains, deltas, levees, and waterfalls.
What are landforms created by rivers?
400
Changes a rock chemically when water flows into the cracks of rocks, evaporates and breaks down the rock.
What is hydration?
400
The most stable ecosystem.
What is a climax community?
400
Boundary where two plates are moving together. Includes subduction and collision boundaries.
What is a convergent boundary?
400
Builds islands.
What is a hot spot (or volcano)?
500
Caves

500
Weathering caused by acid rain.
What is carbonation?
500
Stage of primary succession where shrubs and grass exist.
What is shrub stage?
500
Theory that the continents were once one super continent called Pangaea and have moved to their current position over millions of years.
What is continental drift theory?
500
