Weathering
How are weathering and erosion connected?
Weathering breaks down rocks and erosion moves the broken pieces
True or False: Sediment is an agent of erosion.
What is false. Sediment gets moved during erosion, but it is not doing the eroding.
What is Erosion?
the process of eroding by wind, water, ice, or even gravitational pull.
What comes first, weathering or erosion?
Weathering
Describe how a glacier can carve through rock
As the glacier melts, it starts to move and pick up rocks. The rocks grind against the land.
Aka plucking and abrasion.
What happens after a rock is weathered?
The rock is broken down rock is moved to another location
Which of the following are erosion processes?
A.Gravity erosion- Movement down a slope due of gravity.
B.Running water erosion- Erosion caused by either raindrops or heavy rain.
C. Wave erosion- Occurs due to the action of currents and waves.
D. Wind erosion- Movement of material by the wind.
What are all of the above?
What direction does erosion move earth materials?
Downward with gravity, across with wind or water
Are erosion and weather dependent on one another? Explain
Yes- They both need to occur for the cycle to continue.
What happens after weathering and erosion?
Deposition
Erosion can be caused by what kind of weathering? Must be able to name at least 3
1. Wind 2. Ice 3. Waves 4. Gravity 5. Running Water
What is deposition?
Deposition is when particles are carried by water, wind, ice, and deposited into a new location.
Give an example of how weathering could be destructive.
Weathering may include violent storms, such as a hurricane, or flood. These events or occurences may have long lasting effects.
The three types of chemical weathering
What are oxidation, decomposing in acid, and dissolving in water.
While driving along the highway I noticed huge rocks along the highway. Large nets covered these rocks and seemed to go from the top to the bottom. True or False: these nets put in place to stop weathering or erosion?
True! These nets prevent rockslides.
Put the following in the correct order

A sloping restaurant on the grass puts a cement wall along the side of the building with large boulders. Why? A. To improve the view B. To keep the building from rolling C. They keep the soil in place D. They look nice
C
What is the difference between weathering and erosion?
Weathering is the process of breaking parts of the earth down Erosion Gets rid of the elements of the earth that have moved and are left behind.
The three agents of mechanical weathering.
What are ice, plant growth and animals.
How could erosion be prevented?
Anything that can stop dirt or rocks from moving
Abrasion is the physical process of rubbing, scouring, or scraping whereby particles of rock are eroded away by friction.
Describe why rocks found at the bottom of a river are smooth and flat
They have been weathered by moving water
A land formation that resulted from wind erosion.
What is a sand dune or a mushroom rock?
