Question

what is the result of mechanical weathering?
creation of underground water reserves
formation of mountains
formation of new minerals
breaking down rocks into smaller pieces

Explanation:

Mechanical weathering physically breaks rocks into smaller fragments without changing their chemical composition. The other options are not direct results of mechanical weathering. Creation of underground water reserves is related to hydrological processes, formation of mountains is due to tectonic activities and formation of new minerals is more related to chemical - weathering or geological processes other than mechanical weathering.

Answer:

Breaking down rocks into smaller pieces
