3 Types of Rocks
3 Types of Rocks
Weathering/Erosion
Rock Cycle
100
The thin outer layer of the earth.
What is the crust?
100
This rock forms when sand, particles of rock, bits of soil and remains of once living things are pressed together.
What is sedimentary rock?
100
The three types of rocks.
What is Sedimentary, Metamorphic, Igneous?
100
The breaking up of ROCK into smaller pieces.
What is weathering?
100
The result of cooling lava from a volcano.
What is igneous rock.
200
The thick layer of rock between the crust and the core.
What is the mantle?
200
An example of a sedimentary rock.
What is limestone or sandstone?
200
An example of metamorphic rock.
What is marble/gneiss?
200
The movement of sediment by wind and water is called.
What is erosion?
200
How long does it take for the changes in the rock cycle to occur?
What is a million years?
300
The innermost layer of the Earth.
What is the inner core?
300
Particles of rock and bits of soil.
What are sediments?
300
An example of an igneous rock.
What is obsidian/basalt/granite?
300
When rocks get smooth and break down in bodies of water such as rivers.
What is erosion?
300
The continuous process of rocks forming and changing.
What is the rock cycle?
400
This layer is the only liquid layer.
What is outer core.
400
This rock forms when melted rock from deep below Earth's surface cools and hardens.
What is igenous?
400
This rock forms below the surface where molten rock cools slowly.
What is igneous rock?
400
Give an example of weathering.
What is rain/wind?
400
A rock changes from sedimentary to metamorphic. How?
What is by extreme heat and pressure?
500
In this layer, the rock is soft enough to move like modeling clay.
What is the mantle?
500
Rocks that form when existing rocks are changed by extreme heat and pressure.
What is metamorphic?
500
This rock forms DEEP BELOW earth's surface.
What is metamorphic?
500
When sediments have been DROPPED in a new location?
What is deposition?
500
Sediments turn into sedimentary rock by...
What is pressure?
