Geosphere

Hydrosphere

Explanation:

During a landslide the earths geosphere and hydrosphere are interacting. Landslide is a form of mass wasting by which large mounds of earth moves down slope under gravity.

Landslide is usually triggered by the availability of water which attenuates friction on rock surfaces forcing materials to roll down the slope. It usually occurs after rainfall event.

The water, a component of the hydrosphere acts as lubricant for the earth to move thereby reducing internal friction to nearly zero.

from my research i have to the conclusion that decomposers, such as fungi, bacteria and invertebrates, play a critical role in nutrient cycling and without them the earth's ecosystem may not support life as we know it. elements such as carbon, nitrogen and phosphorus exist in limited amounts on earth, although huge amounts of carbon are being released into the atmosphere from underground sources now by humans. it is still extremely important that other nutrients be retained by the process of re-use. decomposers are organisms that are able to chemically break down dead material and make these elements available for use by other organisms. without this breakdown of dead material, dead bodies would pile up. so decomposers also play a role in clean up also. without them, life might not continue as we know it and dead material would overwhelm the earth.    

the correct answer is b
