Which statement best describes an interaction with the geosphere?
а) glaciers shape a mountain valley
в) rain increases acidity of a lake.
с) carbon dioxide dissolves in oceans.
d) animals release carbon dioxide into the air.

Answer is Option A: Glaciers shape a mountain valley.

Explanation:

'Geo' means ground. Geosphere denotes all minerals and rocks that are present on earth. It also refers to all the mountains found on the surface, the liquid rocks which are present in the mantle under the earth's crust and also the metals which are there in the outer and inner cores of the earth.

Valleys created from glaciers is a form of glacier land form. The eroded ice from the land surface carries the broken rocks which result in formation of glacial land forms.
