Weathering & Erosion
100

This land feature often forms when oceanic plates diverge (separate).

What is a mid-ocean ridge (or new sea floor)?

100
This is the boundary where plates are moving away from each other.
What is divergent boundary?
100
These rocks are frozen magma or lava.
What are igneous rocks?
100
When compacted together these weathered rock particles create a rock type.
What are sediments?
100
The breaking of larger rocks into smaller rocks
What is weathering?
200

This land feature forms when two continental plates collide.

What is a mountain?

200
Divergent boundaries are usually located here.
What is the ocean floor?
200
This type of rock is usually where fossils are found.
What is sedimentary rock?
200
Weathered rock can be compacted to form this rock.
What is sedimentary rock?
200
Ice wedging, plants, wind and animals are agents of this type of weathering.
What is mechanical weathering?
300

This land feature forms in the subduction zone when an oceanic plate collides with a continental plate.

What is an oceanic trench?

300
Mountains can be created at this boundary.
What is a convergent boundary?
300
This rock is created by pressure and heat.
What is metamorphic rock?
300
Without these metamorphic rock could not be formed.
What are heat and pressure?
300
This rock type is the most difficult to weather.
What is igneous rock?
400

When a plate subducts beneath another plate, it will sometimes form a chain of these features.

What are volcanoes?

400
This movement in the mantle causes plates to move.
What are convection currents?
400
This rock is the softest type of rock.
What is sedimentary rock?
400
Lava is called this below Earth's surface
What is magma?
400
Wind, water and ice
What are forces of erosion that can transport materials?
500

When there is a hole in the middle of a plate, magma can push through. This is called a...

What is a hot spot?

500
These zones are where one plate slides under another plate .
What are subduction zones?
500
All rock on this planet originally started out as this rock.
What is igneous rock?
500
Water is necessary to form this rock type.
What is sedimentary rock?
500
Acid rain is an example of this type of weathering.
What is chemical weathering?
