What is the difference between weathering and erosion?
Weathering breaks rocks into smaller pieces; erosion moves those pieces away.

What pulls all objects from higher places to lower places?
Gravity

Explain how plants can weather a rock.
A plant's roots can grow inside a rock, and as they grow, it can break the rock apart.

Name 3 of the 4 ways weathered materials are moved.
Water, ice, gravity, and wind

What is the difference between lava and magma?
Magma is molten rock below earth's surface; lava is molten rock one it is above the earth's surface.

Sample Answers: Plains, plateaus, mountains, peninsulas, valleys, canyons

How can ice cause weathering?
If water gets into the crack of a rock and then freezes, it will expand when it turns into ice. The expanding ice can cause the rock to break into smaller pieces.

Name one difference between landslides and erosion.
Landslides are like a quick version of erosion. Land is moved quickly and all at once rather than little by little.

What is the difference between an active and a dormant volcano?
Active volcano - erupts frequently Dormant volcano - a volcano that has not erupted for a long time

Why might a weathered rock have holes in it?
Different materials weather at different rates.

Name and describe 1 way to control erosion and deposition.
Plants - people can grow plants on hills so the roots keep the soil in place Terraces - slow the speed of water running downhill Barriers - block ocean waves from carrying the sand away

Where on earth's crust are volcanoes located?
Weak spots on Earth's crust; along or near where Earth's plates come together

Explain how actions around a fault can cause an earthquake.
Rocks can get stuck along a fault. The plates continue to move slowly, putting pressure on the rocks. When the pressure is strong enough, the rocks might break, causing the plates to move suddenly. This causes Earth's crust to shake - an earthquake.
