Weathering
What is weathering?
Weathering is the breaking down and changing of rocks.
What is erosion?
Erosion is the transportation of sediments
What is Deposition?
Deposition is when the eroded materials are dropped.
Name 1 one layer of the Earth
Sample Answer: The Inner Core
Name 1 planet
Sample Answer: Earth
Name one type of weathering
Physical and/or Chemical
Name 2 agents of erosion
Sample Answer: Wind and Water
Name 2 agents of Deposition
Sample Answer: Ice and Water
How many layers are there?
6(crust, upper mantle, middle mantle, lower mantle, outer core, inner core)
What is the most famous dwarf planet?
Pluto
What is Physical weathering?
The breakdown of rocks into sediments without changing their composition
How does wind, water, ice, and gravity cause erosion?
Water erodes as it flows above ground through streams or underground through spaces in rocks. Wind erodes as it blows over surfaces and lifts or pushes sediments. Glaciers move like a conveyor belt, eroding soil, sediments, and rocks. Gravity is what causes landsides and waterfalls. Each of those both bring sediments into a new place.
How does Water cause Deposition?
Water carries sediments. When water loses its energy, it drops the sediments, causing deposition.
True or False: The crust is the thickest layer
False
What is chemical weathering?
The altering of rocks as a result of exposure to different substances
How does erosion play a role in shaping the earth's surface?
Erosion moves sediments, soil, and rocks. Erosion can flatten a mountaintop.
How does Deposition help shape the earth's surface?
Deposition is when rocks are dropped. More rocks in a new area can make a place look completely different.
How thin is the Earth's crust?
15 to 20km or 9 to 12mi
Name two examples of physical weathering and two examples of chemical weathering
Sample Answer: Physical- Ice wedging and Exfoliation Chemical- Oxidation and Carbonation
How is Erosion related to Deposition?
Sample Answer: Erosion brings sediments to a new area. When dropped, it causes deposition.
The breaking down and changing of rocks.
Weathering
How hot is the Earth's core?
4400 Celsius or 7952 Fahrenheit( at least)
