Rocks
100
The constant changing of rocks from one type to another.
Rock Cycle
100
The shaking of Earth’s surface caused by the sudden movement of tectonic plates.
Earthquake
100
What is 8. called?
Crust
100
The rocks on Earth are broken down into smaller pieces by the actions of wind, water, ice, and plant roots. This process is called:
Weathering
100
The rock cycle is made up of which types of rocks?
igneous, sedimentary, and metamorphic
200
A crack in Earth’s surface along which tectonic plates move.
Fault
200
A long, narrow, deep ditch in the ocean floor.
Ocean Trench
200
What is 9. called?
Mantle
200
Weathered rock sediments end up in rivers from which process?
Erosion
200
What is a rock that has had heat and pressure applied to it called?
Metamorphic
300
Melted rock under Earth’s surface.
Magma
300
The dropping or settling of Earth's materials.
Deposition
300
What is 10. called?
Core
300
How were the mountains of Pennsylvania formed?
a. collision of continental plates
b. erosion of rock by rainwater
c. collection of groundwater from glaciers
d. deposition of soil by waves
a. collision of continental plates
300
What is a rock that has been weathered and eroded and then squeezed and stuck together called?
Sedimentary
400
When molten rock deep under Earth’s crust rises to the surface.
Volcano
400
The moving and carrying away of Earth's materials by wind and moving water.
Erosion
400
Earth’s plates move very slowly across Earth’s surface on partly melted rock.
Which two layers of Earth make up Earth’s plates?
Crust and Mantle
400
Explain the difference between weathering and erosion
Weathering breaks rocks up into smaller pieces and erosion carries away rocks and pieces of earth.
400
What is a completely melted rock that has hardened called?
Igneous
500
The breaking down of rocks into smaller rocks and soil.
Weathering
500
Small pieces of rock that have been broken down through the process of weathering.
Sediments
500
California periodically experiences earthquakes around the San Andreas Fault. Why?
The plates are sliding past each other.
500
Why might you expect to find volcanoes and earthquakes to happen in the same place?
They occur because of movements in Earth’s crust, so they are most likely to happen near the edges of the tectonic plates.
500
Limestone, Pumice, and Marble are all examples of different types of rocks. Match each type of rock with its correct example.
Limestone= Metamorphic
Pumice= Igneous
Marble= Sedimentary
