Layers of Earth
Miscellaneous
100
The top layer of soil is called.
What is topsoil?
100
This is the type of weathering that occurs when water gets behind rocks when it is cold and cracks the rock.
What is freezing or ice wedging?
100
This is erosion.
What is the movement of sediment from one location to another?
100
These are the layers of the Earth in order from the center to the outer layer.
Inner core, outer core, mantle, crust (lithosphere)
100
This type of rock is made from cooled magma inside Earth's interior.
What is intrusive igneous?
200
This is what makes the topsoil dark.
What are decomposing things, dead decaying organic material or humus?
200
Soil is formed after this takes place for a long period of time.
What is weathering?
200
This is what happens once water carries rocks and particles down a river valley.
What is deposition?
200
This layer of earth is made up of solid metal.
What is the inner core?
200
This type of rock is created from heat and pressure.
What is metamorphic rock?
300
This is how decomposers change the landscape.
What is breaking down dead organic material into nutrients for plants to grow?
300
The Grand Canyon and other canyons were formed from this type of weathering over a long period of time.
What is mechanical weathering or weathering due to water movement?
300
This happens when a volcano erupts melting snow on top of a mountain.
What is mudflow, mudslide, mass wasting or water picking up debris and carrying it down?
300
This layer of Earth is responsible for the magnetic field of Earth and is made of liquid metal.
What is outer core?
300
This type of rock is made in layers after deposition.
What is sedimentary rock?
400
The least permeable type of soil.
What is clay?
400
This is when natural forces such as wind, water and ice cause rock to break down into smaller pieces.
What is mechanical weathering?
400
This is what moves material downward.
What is gravity?
400
This layer of Earth is made up of hot, convecting magma as well as solid rock material.
What is the mantle?
400
This is the process of how a sedimentary rock is formed (consists of 4 words).
What is erosion, deposition, compaction and cementation?
500
This size of soil particle allows for water to travel through quickly.
What is larger soil particle size or pebbles?
500
This is weathering that causes limestone to turn green.
What is chemical weathering?
500
This is erosion that occurs when a large section of loose debris move as a single unit.
What is slump?
500
This layer of Earth is the crust.
What is the lithosphere
500
This is the process of rocks forming and reforming over Earth's timeline.
What is the rock cycle?
