Earth's Surface and Plate Tectonics

Front

What makes up Earth's surface?

Back

Sediment and solid rock make up Earth's surface.

Front

What is bedrock?

Back

Solid rock found on, near, or below the surface of Earth.

Front

What happens to rocks as we move deeper underground?

Back

Rocks become increasingly hotter and compressed, causing them to change state and move more readily.

Front

How does the density of rock below the ocean compare to that below the continents?

Back

Rock deep below the ocean bottom is denser than the rock deep below the continents.

Front

What is the rock cycle?

Back

All rocks can become other rocks.

Front

What are plates in geology?

Back

Sections of bedrock between fault lines of cracks from earthquakes.

Front

Why do plates move?

Back

Plates move because they sit on top of deeper, warmer rock layers which move or creep.

Front

What happens when plates collide?

Back

Mountains can get taller when plates collide.

Front

What causes earthquakes?

Back

Plate movements cause earthquakes.

Front

How do volcanoes form?

Back

Volcanoes occur where an oceanic plate collides with a continental plate, causing the oceanic plate to move under the continental plate.
