12. Explain how underground limestone caves form.

13. Describe how rainwater can be an agent of chemical weathering.

14. Explain how humans can cause erosion.

{easy answers please}

Answer 1

Answer:

1)The Debates Over Limestone Caverns Formation

Subterranean caverns were said to be formed during the process of downcutting of valleys on the surface whereby cave travertines were said to be formed by the abandonment of a cavern level, sometimes extending multiple times, forming multiple levels

2)Chemical weathering describes the chemicals in rainwater making changes to the minerals in a rock. Carbon dioxide from the air is dissolved in rainwater making it slightly acidic. A reaction can occur when the rainwater comes into contact with minerals in the rock, causing weathering.

3)Erosion occurs for several reasons, but a main reason is human activity. When humans disturb the earth with construction, gardening, logging and mining activities the result is a weakening of the topsoil of the earth, which leads to excessive wearing away and erosion
