What is another name for molten rock?
What is magma?
List three ways landforms change?
What is through weathering, erosion, and plants growing into cracks of a cliff.
The layer of the Earth that contains soft areas (molten rock) in which the plates float
What is the mantle?
A theory that explanes how forces deep within Earth can cause continents to move
What is plate tectonics?
What would be a better model of plate movement when an earthquake happens?
a) two blocks of wood rubbing together
b) a bowl of jiggling hair gel
What is a) two blocks of wood rubbing together to show how two tectonic plates slide past each other?
What is the difference between weathering and erosion?
Erosion is the process of moving sediment by wind, moving water, or ice. Weathering is the process of wearing away rocks by natural means.
How does a jetty help protect a beach?

What is a sinkhole. Water can cause underground erosion which causes caves to form. The roof of a cave collapses due to the weight of material above it. If the cave is near the surface, a large hole, called a sinkhole, may suddenly open.

How can wind cause deposition?
What is, wind can cause deposition by blowing sand into the air and dropping it off in another location. This can create a sand dune?
What do earthquakes, mountains, and volcanoes have in common?
Earthquakes, mountains, and volcanoes all happen due to plate movement. Earthquakes happen when two plates rub against each other, mountains are formed when plates converge, and volcanoes are created when a plate moves over a hot spot, like the Hawaiian islands, or when one plate is pushed under another plate, or subduction.
What are deep valleys with steep sides?
What is a canyon
What is the process of wearing away rocks by natural means?
What is weathering.
What causes both earthquakes and volcanic eruptions?
What is plate movement.
What landform can be created from deposition of sediment at the mouth of a river?
What is a delta?
How are canyons formed?
What is they are formed from water erosion. An example is the Grand Canyon.
