What is precipitation?

Back

Precipitation is any form of water, liquid or solid, that falls from clouds and reaches the ground, including rain, snow, sleet, and hail.

Front

What stage of the water cycle occurs on a warm, sunny day?

Back

Evaporation occurs on a warm, sunny day, where water changes from liquid to vapor due to heat.

Front

What process allows plants to convert sunlight into energy?

Back

Photosynthesis is the process by which plants use sunlight to convert carbon dioxide and water into glucose and oxygen.

Front

What is biomagnification?

Back

Biomagnification is the accumulation of pollutants at successive levels of the food chain, leading to higher concentrations in top predators.

Front

Why is water from an aquifer often cleaner than surface water?

Back

Water from an aquifer is cleaner because it is filtered by rock and soil deep within the Earth, removing many pollutants.

Front

What is the water cycle?

Back

The water cycle is the continuous process by which water moves through the environment, including evaporation, condensation, precipitation, and collection.

Front

Define condensation in the context of the water cycle.

Back

Condensation is the process by which water vapor cools and changes back into liquid water, forming clouds.

Front

What is evaporation?

Back

Evaporation is the process by which liquid water is transformed into water vapor, usually due to heat from the sun.

Front

What role does sunlight play in the water cycle?

Back

Sunlight provides the energy needed for evaporation and photosynthesis, driving the water cycle and supporting plant life.

Front

What is the difference between point source and non-point source pollution?

Back

Point source pollution comes from a single, identifiable source, while non-point source pollution comes from multiple, diffuse sources.
