What are latitude (how far north or south) and depth (distance from sunlight)?
300
Water cools to form a liquid and appears as a cloud.
What is condensation?
300
These two problems can occur from the use of dams or levees.
What is removes water from where it should be (prevents a river or stream from continuing to flow) and can cause flooding?
300
Name two ways water can be treated to provide clean drinking water.
