What is subsidence?

Back

Subsidence is the sinking or settling of the ground surface due to the weakening of underground rock layers, often caused by human activities such as excessive water pumping from aquifers.

Front

What does a low pressure system indicate on a weather map?

Back

A low pressure system typically indicates stormy weather, as it is associated with rising air that can lead to cloud formation and precipitation.

Front

Define watershed.

Back

A watershed is the land area that water flows across, under, and through on its way to a body of water, such as a river, lake, or ocean.

Front

Why are watersheds important?

Back

Watersheds are important because they help prevent floods and provide fresh water by managing the flow of water in the environment.

Front

What happens to dye when it is heated in water?

Back

When dye is heated in water, it creates streaks because the hot water is less dense than the cool water, causing the dye to rise.

Front

What is the effect of excessive water pumping from aquifers?

Back

Excessive water pumping from aquifers can lead to subsidence, where the ground sinks due to the removal of water that supports underground rock layers.

Front

What is a tributary?

Back

A tributary is a smaller stream or river that flows into a larger river or lake.

Front

What is a river system?

Back

A river system is a network of rivers and streams that drain into a common body of water.

Front

What is a cold front?

Back

A cold front is a boundary between a mass of cold air and a mass of warm air, often leading to stormy weather.

Front

What is a warm front?

Back

A warm front is a boundary where warm air replaces cold air, typically bringing gradual increases in temperature and precipitation.
