This form of weathering is also known as “rusting”
carbonation

frost action
This type of weathering occurs in areas where the temperature fluctuates around zero degrees Celsius.

Man increases the chance of landslides in all of the follwing ways EXCEPT:
building on unstable slopes
undercutting the base of slopes to build roads
removing vegetation from steep slopes
planting trees on unstable slopes
Which of the following will NOT increase the chance of landslides?
when bedding planes are roughly parallel to the slope surface
when there is an extended period of drought
an earthquake
where there are rocks like shale or clay
Carbonation and oxidation are types of:
climatic weathering
biotic weathering
mechanical weathering
chemical weathering
Removing vegetation tends to ___________ the chances of a mass wasting event.
increase
decrease
does not affect mass wasting
Do mass wasting events always require some sort of trigger such as heavy rains and/or earthquakes?
Yes
No
Why is decreased vegetation a factor that can cause mass wasting?
When plants are removed from the ground, the spaces they leave are filled with heavier rocks.
Decreased vegetation is not a factor that causes mass wasting.
Vegetation stabilizes soil at the surface, and their roots anchor soil under the surface.
Decreased vegetation is not a factor that causes mass wasting.
Include geological phenomena and processes that originate externally to the Earth's surface.
Exogenic Processes
Endogenic Processes
