The process where rocks from Earth's crust are slowly being broken into smaller pieces is called...
Weathering
100
What is the difference between weathering and erosion?
Weathering breaks rocks into smaller pieces; erosion moves those pieces away.

What type of moving plates cause a volcano?
Converging, Diverging, Translating
Diverging
100
The outer most layer of the earth.
What is the crust?
100
Name the three types of rocks.
Igneous, Sedimentary, Metamorphic
200
What are 3 of the 4 physical causes of weathering?
Water, ice, temperature change, and living things
200
The laying down of pieces of Earth's surface is called...
Deposition
200
Volcanic eruptions produce...
Rock , lava, and ash
200
The layer that lies directly below the crust. Describe the substance.
Mantle, flowing rock
200
How are igneous rocks formed?
Magma rising to the surface, becoming lava and cooling to form hard rock
300
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.
300
Name 3 of the 4 ways weathered materials are moved.
Water, ice, gravity, and wind
300
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.
300
What the outer core is made of.
Molten rock.
300
Name the possible layers that could form a sedimentary rock?
dead plants, animal bones, mud, sand, rock
400
How can ice cause physical 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.

Put these in order they occur.
Erosion, Deposition and Weathering

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
400
The plates were once all together as one super continent.
What is Pangea?
400
An igneous rock always stays an igneous rock.
True or False? Support your answer.
False. An igneous rock can break down into a sedimentar rock, sink back into the Earth and becom a metamorphic rock and then melt down and come back to Earth as an igneous rock.
500
Name the 2 types of weathering and how they are different.
Physical and chemical weathering.
Physical weathering changes the size and physical appearance of rocks. Chemical weathering causes rocks to change into different materials.
500
Name and describe 3 ways 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
500
Where on earth's crust are volcanoes located?
Weak spots on Earth's crust; along or near where Earth's plates come together
