Weather, Climate, & Watersheds Review

Front

What is a watershed?

Back

A watershed is an area of land where all the water that falls as precipitation drains into a common outlet, such as a river, lake, or ocean.

Front

How does location within a watershed affect water quality?

Back

The quality of water is generally better in areas with less industry and pollution, while areas near farmland may have runoff that affects water quality.

Front

What is runoff?

Back

Runoff is water that flows over land and eventually enters streams, rivers, or lakes after precipitation.

Front

What is the relationship between air temperature and density?

Back

Cold air is more dense than warm air, which causes warm air to rise.

Front

What are trade winds?

Back

Trade winds are prevailing winds that blow from east to west in the tropics, influencing weather patterns.

Front

What is El Niño?

Back

El Niño is a climate pattern characterized by the warming of ocean surface temperatures in the central and eastern Pacific Ocean, affecting global weather.

Front

What is La Niña?

Back

La Niña is a climate pattern that describes the cooling of ocean surface temperatures in the central and eastern Pacific Ocean, often leading to opposite weather effects of El Niño.

Front

What is precipitation?

Back

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

Front

What is condensation?

Back

Condensation is the process by which water vapor in the air is changed into liquid water, often forming clouds.

Front

What is transpiration?

Back

Transpiration is the process by which water is absorbed by plants and then released as water vapor into the atmosphere.
