What are the three main stages of a thunderstorm?
What is air currents moving upward, air currents mixing, and last all air currents move downward?

What is climate?
What is the average of weather conditions over a long time, usually thirty years?

What is it called when gases or liquids rise and sink in a circular pattern?
What is a convection current?

What are the four types of air masses?
What is Continental Tropical Air, Continental Polar Air, Maritime Tropical Air, and Maritime Polar Air?

What are four examples of severe weather?
What are blizzards, thunderstorms, tornadoes, hurricanes, and high or low temperatures?
200
What is an anemometer?
What is an instrument that measures win speed?

How is weather different from climate?
What is weather consists of conditions in one place at one time? Climate is the average of weather conditions over a period of time.
300
What causes convection currents?
What is when different temperatures between air over land and water.
300
How do air masses form and move?
What is air masses form when air stays over an area for some time and takes on the temperature and water vapor of that area? Upper level winds move air masses.
300
What causes a tornado?
What is layers of wind in a storm blow at different speeds or in different directions. Then, a horizontal column of spinning air is forced upright by winds blowing in upward and downward directions, forming a funnel could. If the funnel cloud touches the ground, it is called a tornado.

How does a weather forecaster know the weather ahead of time?
What is they make predictions based on current weather conditions, patterns of the past, conditions in areas around us, and different tools that allow them see different weather parts.

How are fossils used to study past climates?
What is scientists can make assumptions about ancient climates based on similarities between fossils and modern organisms?
400
How is warm air and cool air different?
What is warm air molecules are more spread out, where as cool air molecules are closer together?
400
Why does precipitation often happen at fronts?
What is because warm air is forced to rise by a cold front, causing water vapor in the warm air to condense and fall as rain?
400
What are the effects of a hurricane?
What is destruction by high winds, heavy rains, waves pounding the shores, and flooding?
400
What kind of weather systems are found in areas of high air pressure? Low air pressure?
What is high air pressure often have clear skies. Low air pressure areas usually have cloudy skies.

What can cause sudden climate change?
What is volcanic eruptions and asteroid impacts?
500
How many convection currents form in the air about the Earth?
What is six?

How can you prepare for severe weather?
What is by possibly boarding up windows, storing food, water, having shelter, blankets, keeping valuables in plastic containers off the ground, flashlights, etc.

What are the parts of the weather system?
What are temperature, moisture, air pressure, clouds, precipitation, wind speed, and direction?
