@megax

Answer 2

the size of a rock now can i geh a medal

Answer 3

it's D. 100% sure.

Answer 4

There is a difference between mechanical and chemical weathering
Mechanical weathering is the physical process by which the structure of the rock is changed, without altering the chemical composition of the rock itself.
Chemical weathering consists in dissolving minerals into more soluble compounds, changing the chemical composition of the rock.

Conclusively, the answer cannot be D, @sbuck98, because when shape of rock is changed, granules are detached from rock, thus the weight changes.

It cannot be A, @cookie_kvng , because for instance in the process of thawing, it consists in water entering on cracks of rocks and widen them during freezing. At thawing, water evaporates, living more space for water to enter and enlarge the crack even more during freezing. As you can see, the size of the rock will increase.

Similarly, shape is changed, under the process of wetting and drying, where due to expansion and contraction of rock, it eventually breaks open as it is not flexible to such phenomena. It then changes from a roughly circular shape and once broken, a semi-circular shape.

According to the definition of mechanical weathering that I said at the beginning, the answer is B.

Answer 5

rocks dont move or change unless its a dirt rock
