What is a sinkhole?
The cycling of water from Earth's surface, into the atmosphere, & back.
What is the water cycle?
Th study of geology that focuses on the distribution & movement of groundwater in the solid & rocks of Earth's crust.
What is hydrogeology?
The presence in or introduction into the environment of a substance or thing that has harmful or poisonous effects
