Water cycle
As water changes states, it moves between the air and Earth in a process called what?
The water cycle!!!
would a puddle evaporate faster on a warm day or on a cool day?
Warm day. water molecules will move faster in heat making the water evaporate faster
A puddle you saw in the morning before school has now dried up after you leave. The puddle just went through what stage of the water cycle?
Evaporation
What are the tiny water droplets on leaves or grass in the early morning called?
Dew
which state of matter is mostly invisible to the eye?
GAS
What are the four forms of precipitation?
Rain, sleet, snow, and Hail
what will melt faster, A single ice cube or a snowman? why?
The ice cube because it is smaller so there is less water to evaporate
Dew forms on leaves and grass early in the morning due to what phase of the water cycle?
Condensation
Where does the runoff water collect or join together?
into oceans, ponds, rivers, and lakes
What are the tiny things that make up everything called? we cannot see them.
Molecules
Any form of water that falls from the clouds to earth is called what?
Precipitation
What is the state of matter in which we cannot see water?
Gas (water vapor)
Rain, snow, sleet, and hail are all forms of?
Precipitation
The water cycle renews water so that it becomes???
FRESH WATER
What are waters three states of matter called?
Ice (solid), Water (liquid), And Water Vapor (gas)
the change of state from a gas to a liquid is known as what?
Condensation
To freeze water what has to happen to the molecules?
They need to slow down (less energy)
Water that does not soak into the ground and flows downhill is called?
Runoff
Do living things only give or use and return water to the water cycle?
use and return
This is one of the few things that can be found in all three states of matter, what is it?
WATER
the change of state from a liquid to a gas is called?
Evaporation
To make water evaporate you need to add more energy? or less energy?
More energy (this means applying more heat or making the molecules move faster)
Precipitation that soaks into the ground becomes what?
Ground water
What is the layer if air that cover the Earths surface?
Name the three states of matter
Solid, Liquid, Gas
