100
Breaking of rocks into smaller pieces by water, wind, and other forces.
What is weathering?
200
Huge land mass that broke up long ago into today's continents.
What is Pangaea?

Long underwater mountain chain where plates move apart.
What is mid-ocean ridge?
200
The sinking of the edge of one plate below the edge of another.
What is subduction?
200
Crack in Earth's crust along which movement can occur.
What is a fault?
200
Point of Earth's surface directly above the focus of an earthquake.
What is epicenter?
300
Hot region of Earth's upper mantle that flows very slowly.
What is asthenosphere?
300
Slow, continual formation and destruction of rock and rock materials.
What is rock cycle?

Alfred Wegener was lacking this in his theory of continental drift.
What is an explanation of how or why the continents moved?
400
New crust forms at these plate boundaries.
What is divergent?
400
Plates do this at convergent plate boundaries.
What is collide?
400
The San Andreas Fault, where blocks of rock scrape past each other.

400
This scientific instrument is used to record earthquake waves.
What is a seismograph?
400
Acid rain is a cause of this.
What is chemical weathering?
500

Earthquakes are vibrations of the ground produced when this happens.

What is Plates slide at a transform boundary?

500
Rock formed when heat and pressure inside Earth change one kind of rock into another rock.
