What is the primary use of water in agriculture?

Back

Irrigation

Front

What happens to dissolved oxygen (DO) and biological oxygen demand (BOD) levels at the point of contamination with organic contaminants?

Back

Dissolved oxygen (DO) levels decline and biological oxygen demand (BOD) levels rise as a result of an increase in aerobic bacteria levels.

Front

What is the term for water that flows over land and returns to bodies of water?

Back

Runoff

Front

What is the relationship between dissolved oxygen (D.O.) and biological oxygen demand (B.O.D.)?

Back

When B.O.D. increases, the D.O. decreases.

Front

What are the main uses of water?

Back

Agriculture, drinking water, industrial processes, and transportation.

Front

Define the hydrosphere.

Back

The hydrosphere encompasses all water on Earth, including oceans, rivers, lakes, and groundwater.

Front

What is the water cycle?

Back

The continuous movement of water through evaporation, condensation, precipitation, and runoff.

Front

Back

The process by which water changes from a liquid to a gas or vapor.

Front

What is condensation?

Back

The process by which water vapor cools and changes back into liquid water, forming clouds.

Front

What is precipitation?
