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.
Runoff
This rock forms from magma or lava when it cools
Igneous
Sedimentary rocks are changed into sediment by these processes.
Weathering and erosion
When water freezes in cracks and expands, breaking rock apart, this type of weathering occurs.
Physical weathering
When sediment slows down and is dropped in a new location, this occurs.
Deposition
More vegetation usually causes runoff to ____.
Decrease
This rock forms when sediments are compacted and cemented together.
Sedimentary
Large crystals form when magma cools ____.
Slowly
This type of weathering happens when minerals in rocks are changed by chemical reactions.
Chemical Weathering
In a river, erosion usually happens where the water is ____.
Fast Moving
Steeper slopes cause runoff to ____.
Increase
This rock forms deep underground due to heat and pressure.
Metamorphic Rock
The deeper rocks are in Earth’s crust, the greater the ______ and _______.
Heat and pressure
How can water cause weathering?
issolving minerals, flowing over rock, and freezing in cracks.
A landform created by deposition at the mouth of a river is called a ____.
Delta
What are things that influence runoff
amount of rainfall, slope of land, vegetation
Foliated metamorphic rocks are identified by these.
Layers
Which process does NOT change rocks at Earth’s surface?
-erosion
-weathering
-magnetic field
-melting
Magnetic field
Breaking a candle into pieces and pressing them together best models this process.
compaction
When rocks are broken into small pieces it is called
sediment
Can water affect where and impact crater is? If so, how?
water will fill in the impact crater and weather it
What is the process called for Rocks change over time due to weathering, erosion, deposition, heat, pressure, and melting.
Rock cycle
Letting melted candle wax cool and harden best models this rock type.
Igneous
