As parts of Earth’s surface are broken down, other parts are built up. (blank) is the laying down of Earth’s surface. Sometimes this happens slowly, and at other times it happens very fast.
deposition

Do volcanoes cause slow or rapid change to Earth’s surface?
rapid change

Earth’s outer layer, or crust, rests on top of another layer called the upper mantle. These two layers, together, are divided into very large pieces called what?
plates

Water, ice, gravity, and wind often work together to move weathered pieces of rock. This process is called what?
erosion

Is temperature change an example of physical weathering or chemical weathering?
physical

Give me two ways that people control erosion
terraces, planting trees or bushes, building walls in front of water

Underground, very hot molten or liquid rock is called what?
magma

The process of rocks being broken down into smaller pieces is called what?
weathering

Give me two things that cause weathering
water, ice, temp change, chemicals, living things

How was the Grand Canyon formed?
a river flowing through the area wore away the land

What is the difference between violent eruptions and quiet eruptions?
violent eruptions occur when gas builds up and the top of the volcano explodes, quiet eruptions are when the lava oozes up out of the volcano

weathering is the breakdown of materials and erosion is the moving of those broken down parts

What is the difference between an active, dormant, and extinct volcano?
active has frequent eruptions, dormant is a volcano that has not erupted in a long time, and an extinct volcano will not erupt again

What is a fault?
a break or crack in rocks where Earth’s crust can move

How does an earthquake start?
