Answer:
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.
