Answer:

1.Chemical weathering is the transformation of rock-forming primary minerals into dissolved substances and secondary mineral residues under the influence of water, acids, complexing agents and oxygen.

2.Reasons causing the rise in sea level

As the planet gets warmer, sea level rises for two reasons. First, warmer temperatures cause ice on land like glaciers and ice sheets to melt, and the meltwater flows into the ocean to increase sea level. Second, warm water expands and takes up more space than colder water, increasing the volume of water in the sea

3.Humans can contribute to mass wasting in a few different ways: ... in many situations there are actions that we can take to reduce or mitigate its ... wasting is road construction, and this applies both to remote gravel roads built for forestry and ... heavier than the fill that was removed from the hole in the ground made to build it.

4.Image result for what agent of weathering changes the rock formation?

Chemical weathering changes the molecular structure of rocks and soil. For instance, carbon dioxide from the air or soil sometimes combines with water in a process called carbonation. This produces a weak acid, called carbonic acid, that can dissolve rock. Carbonic acid is especially effective at dissolving limestone
