This weather tool is used to measure the temperature.
What is a thermometer?
100
This is when water from a body of water, such as a lake or an ocean, is heated by the sun and turns into water vapor.
What is evaporation?
100
This is what makes clouds move.
What is the wind?
100
This type of precipitation occurs when water droplets collect together as clouds and then when the droplets become heavy, because of gravity, they fall to the ground.
What is rain?
100
When the barometer indicates that there is high pressure in the air, we will be having this type of weather.
What is good weather?
200
This weather tool tells the direction that the wind is blowing.
What is a weather vane?
200
This is when water vapor in the air is changed into liquid water.
What is condensation?
200
This is what clouds are made of.
What are water droplets.
200
This is rain that falls to the ground and then freezes after it hits the ground.
What is freezing rain?
200
This is a person who studies weather.
What is a meteorologist?
300
This weather tool measures the amount of rain that has fallen.
What is a rain gauge?
300
This is any form of water that falls to the earth's surface.
What is precipitation?
300
These clouds are high in the atmosphere. They are thin, wispy clouds blown in high winds into long streamers. They are usually white and predict fair to pleasant weather.
What are cirrus clouds?
300
This is when snow falls from the clouds, goes through a band of warm air that causes it to melt, then refreezes into frozen balls before it hits the ground.
What is sleet?
300
This is the state of the atmosphere at any given time.
What is weather?
400
This weather tool measures the speed of the wind.
What is an anemometer?
400
This is the water flow that occurs when the soil is saturated and excess water flows over land.
What is run off?
400
These clouds are white, puffy clouds that look like floating pieces of cotton. The base of each cloud is flat and the top of each cloud looks like cauliflower. These clouds can develop into thunderstorm clouds.
What are cumulus clouds?
400
These are ice crystals that form in the atmosphere. The temperature must be below 32 degrees for these to form.
What is snow?
400
This is the kind of pressure in the air when the green water in the tube of the barometer is high and near the top of the tube.
What is low pressure?
500
This weather tools measures the amount of pressure in the air.
What is a barometer?
500
This is when moisture is carried through plants from roots to small pores on the bottom of leaves, where it changes to vapor and is released into the air.
What is transpiration?
500
These clouds are uniform grayish clouds that often cover the entire sky. They look like fog that doesn't reach the ground.
What are stratus clouds?
500
This type of precipitation begins as a frozen raindrop. Strong updrafts move the frozen particle up and down through different levels of a storm cloud, making it get larger and larger until it is heavy enough to fall to the ground.
