What is weathering?
Weathering is the breaking down of rocks into smaller pieces.
100

Valley
200
This is a body of fresh water that is completely surrounded by land.
Lake
200
This is the deepest, hottest layer of the Earth.

When water flows over land that is usually dry, it is called this.
Flood
200
When weathered rocks are dropped off in new places, it is called this.
Deposition
200
This is the rapid movement of rocks and soil down a hill.
Landslide
300
This is land with water surrounding it on three sides.
Peninsula
300
This is the layer in between the crust and the core, made up of both solid rock and nearly melted rock.
Mantle
300
Name the force that can cause a landslide.
Gravity
300
The weathering of rocks can take this many years.
Millions
300
The seven great areas of land on Earth are called this.
Continents
400
This is a huge plateau found underwater, near the edge of a continent.
Continental shelf
400
This is the layer of the Earth where earthquakes occur.
Crust
400
Name the scale used to measure earthquakes.
Richter Scale
400
Name three things that can cause erosion.
(1) Moving water, (2) wind, (3) glaciers
400
This is land with steep sides and a flat top.
Plateau
500
This is a canyon on the ocean floor.
Trench
500
Write the difference between the outer core and the inner core.
The outer core is melted rock, and the inner core is solid rock.
500
Write the difference between magma and lava.
Magma is the melted rock in the mantle and crust, and lava is what it is called when it flows onto the land.
500
Name four things that can cause weathering.
(1) Running water, (2) wind, (3) rain, (4) temperature changes

What is the difference between a destructive volcano and a constructive volcano?
A destructive volcano destroys the land around it, and a constructive volcano builds up or adds to the land around it.
