The tool used to measure air pressure.
What is a barometer?

Explain the steps of the water cycle.
Water evaporates from oceans and lakes. Then as the water rises, it cools and condenses into a cloud. The cloud becomes too heavy and eventually the water falls to the earth as precipitation.

What are the two most influential effects of the climate?
Latitude and closeness to the ocean.

So that you will know whether it is going to flood or not.

The tool is used to measure humidity.
What is hygrometer?

What is the sun's role in the water cycle?
The sun's warmth evaporates the water on the earth.
500
What would happen if we did not have oxygen, carbon dioxide or water vapor in our atmosphere? Be specific for each gas.
People could not breathe without oxygen. Plants could not live without carbon dioxide. The water cycle could not continue without water vapor and the water on earth would dry up. There couldn't be life without these gases.

Predicting a regions' weather is called . . .
What is forecasting?

Name two similarities of a hurricane and tornado. Name two differences for each.
Hurricane's and Tornadoes both have strong winds and are destructive. Hurricane's are larger, last longer and form in the ocean. Tornadoes last for a shorter amount of time, are smaller and form from a thunderstorm.
