How does chemical weathering differ from physical weathering? A. It causes rocks to change color B. It increases the size of the rock C. It makes the rock stronger D. It makes the rock disappear

A. It causes rocks to change color

Explanation:

Weathering can be defined as the gradual decomposition of rock. This means, rocks are broken into pieces or sediments through the process of weathering.

There are two types of weathering process:

1. Physical weathering also known as mechanical weathering. This is the breakdown of rocks into smaller pieces without changing the composition of the rock. Physical weathering is caused by the action of ice, wind, plant growth.

2. Chemical weathering: Here, the rocks changes not just in size of pieces but in its composition. This is when other minerals are applied on the rock in other to dissolve it.

the potential energy of the reactants is 200j.

from the energy diagram, the energy of the product formed is 350j; this means that, this reaction is an endothermic reaction, because it absorbs energy from its environment.
