Weathering
This process breaks rocks into smaller pieces without changing the minerals.
Physical Weathering
The movement of sediment by water, wind, ice, or gravity is called ____.
Erosion
Rain, vegetation, and slope all affect this.
Run off
The three types of rocks are
Sedimentary, Igneous, and Metamorphic
Weathering and Erosion
When a rock is broken down over time due to water, wind, or temperature changes
Weathering
When sediment slows down and is dropped in a new location, this occurs
Deposition
More vegetation usually causes runoff to ____.
Decrease
This type of rock is formed when magma or lava cools
Igneous Rock
Large crystals form when magma cools ____.
(Hint: Speed)
Slowly
When water freezes in cracks and expands, breaking rock apart, this type of weathering occurs
Physical Weathering
In a river, erosion usually happens where the water is ____. (Hint: Speed of the river)
Fast moving
Steeper slopes cause runoff to ____.
Increase
This type of rock is formed from intense heat or pressure
Metamorphic Rock
The deeper rocks are in Earth's crust the more this increases.
Pressure
Water weathers rocks by dissolving minerals, flowing over rock, and freezing in cracks.
Physical Weathering
Deposition
When water can no longer soak into the ground it can become ______.
Run off water
This type of rock is usually found on the surface, can contain fossils, and is made up of layers of sediment that are weathered, eroded, deposited, and compacted
Sedimentary Rock
True or False: Magnetic fields help shape Earth's surface
False
This type of weathering happens when minerals in rocks are changed by chemical reactions
Chemical Weathering
Rocks being broken down and carried down a river is an example of
Erosion
True or False: Run off water is a form of erosion
True
Igneous Rock
Rock types can change at any time from one type to another, or from the same type and back to the same type, this is known as the _____ ______.
Rock Cycle
