What is one characteristic of the groundwater that forms caves? a. it is very hot. b. it is very cold. c. it is slightly acidic. d. it is slightly basic.

Groundwater that forms caves because it is slightly acidic.

Explanation:

The water under the ground present inside the cracks and spaces in sand, soil and rocks is called ground water.

When ground water moves through the soil it results in the formation of acid. Further, this acid helps minerals to get dissolve. These minerals get deposited on other places as well.

This process of deposition and erosion helps in the formation of caves.

Thus, it can be concluded that groundwater that forms caves because it is slightly acidic.

metals are good conductor of electricity. it has free electrons on their surface. according to electron pool theory, each atom present in a metal crystal losses all of its valence electron and as a result a pool of free is form. these pool of electrons are free to move and   conduct electricity easily   while making metal as good conductor.

the correct answer is a. the ability of electrons to flow throughout the metal.
