Which of the following is not an example of a mass movement?
to. a. Ground slides b) acid rain c. mud flow d. drop
Answer:
b) acid rain
Explanation:
Acid rain is not an example or a type of mass movement.
Mass movement or mass wasting is the movement of rocks, soils and other debris downslope under the influence of gravity.
Water, slope and gravity are triggers of mass movement.
- Acid rain is a not a form of mass movement
- It occurs with some certain gases mixes rain water to produce an acidic precipitation.
- When the water falls to the each surface, it causes problems to the ecosystem and can also corrode building materials.
Well electrons are like electricity well it is partly if it went 3 sub levels the electrons would blow up some electricty<span />

The health of coral colonies
The levels of carbon dioxide in the atmosphere
This is because corals are very sensitive to changes in the ocean's properties pH being included. Warmer oceans dissolves more carbon dioxide from the atmosphere hence making the waters slightly acidic. This will affect coral resulting in bleaching. This negatively affects the marine ecosystems since corals are usually at the bottom of the energy pyramid in these ecosystems.

Chlorofluorocarbons are very harmful to the environment when released into the atmosphere. They damage the ozone layer and therefore allow more UV rays from sunlight to reach the earth’s surface. They also have a greenhouse effect causing the earth’s atmosphere to warm up. This ultimately leads to global warming and climate change.

It would allow storm systems to stall in an area
Jets streams are very significant in that they influence weather patterns across the world. They are responsible for the movement of pressure systems and global air cells and their accompanying weather patterns. Because they generally sit in between cold and warm air systems they are significant in moving these air masses around. When they are weak they cause an air system to linger including storms causing excessive flooding in an area.

Absorb and re-emit infrared radiation.
Produced by human activity
Greenhouse gases do not allow infrared radiation from the earth's surface to escape back to space. Infrared is the electromagnetic wave spectrum responsible for transferring heat energy. Therefore, when left to linger in the atmosphere, they cause the greenhouse effect. This is the reason for global warming.
