Explain how ocean currents help regulate Earth's climate.

Explain how the government is determining which specific lands should be allowed to flood once flood control mechanisms are abandoned.

Caverns form the dissolution of ___________________ because rainwater reacts with atmospheric carbon dioxide to become slightly acidic.

If you are a scuba diver and submerge into the depths of a lake, you will encounter a boundary where between the warm upper layers and the cold deeper layers of water in the lake, which is called the ____________________.

If you see a stream in the desert that only flows during monsoon season, what specific type of stream are you observing? ____________________

If a person utilizes a renewable energy resource by harnessing the heat from the Earth's interior or radioactive rocks that generate heat, what type of renewable energy have they used?

Explain how flood control mechanisms can impact humans over time.

Explain why humans have filled, drained, mined, and turned wetlands into agricultural land over history and discuss why this practice was not a good environmental choice.

Explain how a river with a higher gradient may not flow as fast as a river with high discharge and provide an example of each type.
