Evaporation
What is it called when liquid water changes into a gas that floats up to the sky?
Evaporation
What is it called when water vapor changes back into liquid water?
Condensation
What is water called when it falls from clouds to Earth?
Precipitation
What is it called when water gathers in lakes, rivers, ponds, or oceans?
Collection
What is the order of the Water Cycle?
Evaporation, Condensation, Precipitation, & Collection/Runoff
Name 1 example of evaporation ... that isn't a puddle on the ground!
Clothes drying | Sweating | Mopped floors | Nail polish remover
Does cooling or warming cause condensation?
Cooling
Name the four kinds of precipitation
Rain, Hail, Snow, and Sleet
What is water called when it flows across the ground after it rains?
Runoff
Does the water cycle end, or is it in a continuous loop?
A. Ends after Collection & Runoff
B. Continuous Loop
When water evaporates from the ground and turns into a gas, what is that gas called?
Water Vapor
Are the tiny drops in fog water vapor or liquid water?
Liquid Water
Does condensation (clouds) automatically mean precipitation will happen?
No — the water droplets have to be heavy enough!
What is the water that soaks into the soil called?
Groundwater
BONUS: the process is called infiltration
What gives water most of the energy it needs to evaporate?
The Sun / Heat
What 3 things are needed to make a cloud?
Water Vapor, Cool Air, and Particles of Dust/Dirt/Smoke
Why does it snow or hail instead of rain?
Because the air on the way down to Earth is so cold, the droplets freeze!
The same rain falls on grass and a parking lot. Which will probably have more runoff?
The parking lot ... the grass will soak most of it up!
Does water gain or lose heat energy when it evaporates?
Gain — the very tiny molecules begin dancing around really fast when they're hot!
If fog warms up and disappears, what happened to the tiny water droplets in it?
They evaporate! (back into water vapor)
What else releases water vapor besides puddles of water? (something above ground)
Plants! They release water vapor from their leaves!
