Water and the Weather Flashcard

Front

What is transpiration?

Back

Transpiration is the process by which water evaporates from the leaves of plants into the atmosphere.

Front

Where does most water vapor in Earth's atmosphere come from?

Back

Most water vapor comes from the evaporation of water from the surfaces of the oceans.

Front

What force causes rain, snow, or sleet to fall to the ground?

Back

Gravity is the force that causes the downward movement of water as raindrops, snowflakes, hail, or sleet.

Front

What are snowflakes made of?

Back

Snowflakes are formed when water vapor crystallizes around dust particles or other ice crystals.

Front

What is a cloud?

Back

A cloud is a collection of liquid water droplets or solid ice crystals that are visible in the atmosphere.

Front

What is evaporation?

Back

Evaporation is the process by which water changes from a liquid to a gas, often due to heat.

Front

What is condensation?

Back

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

Front

What role do oceans play in the water cycle?

Back

Oceans are the primary source of water vapor in the atmosphere due to evaporation.

Front

What is precipitation?

Back

Precipitation is any form of water, such as rain, snow, sleet, or hail, that falls from the atmosphere to the Earth's surface.

Front

What is humidity?

Back

Humidity is the amount of water vapor present in the air.
