100

A puddle on the sidewalk disappears on a hot, sunny day.

What is evaporation? 

100

Water that falls from the sky as rain, snow, sleet, or hail

What is precipitation? 

100

The sun heats up water on Earth's surface.  What happens next?

Evaporation increases. 

100

What is the main energy source that drives the water cycle? Example: It causes water to change into a gas. 

The sun

100

You see tiny droplets forming on your car windows on a cold morning.  Which process is happening?

Condensation 

200

White puffy clouds appear in the afternoon as warm air cools

What is condensation?

200

Liquid water turns into gas when it gains heat.

what is evaporation?

200

The air temperature drops and becomes saturated. What happens next> 

Condensation and cloud formation.

200

What force causes precipitation to fall and rivers to flow downhill?

Gravity

200

Rainwater moves downhill to rivers and back to the ocean.  Which process is happening?

Surface runoff.

300

Rainwater sinks into the soil and moves underground

What is infilitration?

300

Water moving underground.

What is in ground water? 

300

After several rainy days, the soil can't absorb more water.  What happens?

Runoff increases.

300

Why do scientist call it the "water cycle" Instead of a water path.

Because it has no starting or ending point-it's continuous

300

Water escapes from plants and enters the air as vapor. Which process is happening?

Transpiration

400

Ice on a mountain top turns into water vapor without melting first? 

What is sublimation?

400

The continuous movement of water between land, oceans, and atmosphere

What is the water cycle? 

400

Warm air rises quickly, cools fast, and forms big clouds.  What type of precipitation might occur?

Heavy rain or hail.

400

Name one human activity that changes how water moves through the cycle. 

Building cities (more runoff), cutting down trees (less transpiration)

400

After a storm, water seeps deep into soil layers. Which process is happening?

Infiltration/percolation

500

Water exits tiny holes in leaves as invisible gas.

What is transpriation?

500

Water vapor changing into liquid to form clouds.

What is condensation?

500
Moist air blows toward a mountain.  Explain what happens on eat side. 

heavy precipitation; leeward side: dry rain shadow.

500
Predict how drought would affect evaporations, transpiration, and precipition


All three would decrease because there's less water available. 

500

Water from a lake becomes vapor, form clouds, then falls to the ground.  PUt these in order?

Evaporation, condensation, precipitation
