Measuring Weather
Clouds and Water Cycle
100

This layer of the atmosphere plays destroys asteroids / meteors that threaten Earth

What is Mesosphere?

100
This material made out of the compressed remains of prehistoric animals is used to power our homes, cars, and factories.

What is Fossil Fuel?

100
Warm air masses tend to form around the middle of the globe, a location known as

What is the equator / tropical zone?

100

This tool detects changes in air temperature.

Thermometer

100

This type of cloud usually accompanies thunderstorms.

What is a cumulonimbus?

200
This layer of the atmosphere has the greatest air pressure acting on it

What is the Troposphere?

200

The gases produced by burning fossil fuels lead to a __________ in the temperature on planet Earth?

What is "increase"?

200

Cold air masses that form at the top or bottom of the globe are called

What are polar air masses?
200

This tool detects changes in wind speed.

What is anemometer?

200

This step of the water cycle involves water in lakes, rivers, and oceans turning into gas.

Evaporation
300

The stratosphere contains this special area that absorbs dangerous UV radiation from the sun.

What is the Ozone layer?

300
This greenhouse gas is the most common one produced by humans burning fossil fuels.

CO2

300

This type of pressure system sucks air up into the sky, often resulting in storms and similar weather.

Low pressure system
300
Changes in air pressure might signal a storm is coming. We measure these changes with...

Barometer

300

When water vapor is released from plants and the breath of animals on Earth we call it

Transpiration

400

Most layers of the atmosphere show decreases in temperature as you go higher in altitude. Not this one!

What is the Thermosphere?

400

Water vapor, CO2 (carbon dioxide), and methane make up a very small percentage of the Earth's atmosphere, but they contribute to a big phenomenon called:

What is the Greenhouse effect?

400

When two air masses collide together they make this: a boundary where severe weather often occurs

What is a front?

400

A device that can collect precipitation to determine how much fell.

Rain gauge

400
Clouds are formed as water changes from a gas to a liquid in this step of the water cycle:

Condensation

500

The majority of the Earth's atmosphere is made out of this gas.

What is Nitrogen?

500

This would occur if there were too few greenhouse gases on Earth.

What is global cooling / freezing / decrease?

500
When a cold mass of air pushes warm air up into the sky quickly we call it a ___________

What is a cold front?

500

This tool can detect changes in humidity.

What is a hygrometer?

500

If a cloud covers the sky like a big gray blanket and brings rain but no storms, it's most likely

Stratus
