Where does infiltration occur?

a. in the atmosphere

b. in the biosphere

c. in the geosphere

d. in the hydrosphere

Answer - C. In the Geosphere 

Reason - It is where volcanic, tectonic places and rifts occurs which is the crust of the earth. Without the geosphere aka crust we wont be able to have a solid piece of land to stand on.

Infiltration is the process by which water on the ground surface enters the soil. So, the answer will surely be the C in the geosphere.

Wetlands form where water and land meet. a lake with a wetland fringe can fill in with decayed plant and animal material to become a wet meadow. a pond can fill in to become a bog or fen. sediment can fill in a river marsh to become a swamp.flooding of coastal lowlands from rising sea levels has created broad coastal marshes that are protected from wave action by barrier islands or reefs. coastal wetlands also form when rivers deposit sediment as they reach the ocean. plants then take root and hold the soil firm against the forces of tides and waves.
