Weather Unit Review

Jim made the model to represent the gases in the atmosphere. The O stands for oxygen, the N stands for nitrogen, and CO stands for carbon dioxide.
Why did he write down N and O  so many times and only CO once?

• Because plants need carbon dioxide
• Because most of the air is nitrogen and oxygen
• Because oxygen and nitrogen are more important
• Because we need oxygen to breathe.

A class used the setup to model the water cycle. Water droplets formed on the bottom of the glass cover.
How did the water droplets most likely form on the bottom of the glass cover?

• Runoff from the water wet the glass.
• Water vapor condensed on the glass
• The ice cubes melted and wet the glass.
• The drops of water precipitated onto the glass.

How do the conditions for a tornado differ from the conditions for a hurricane?

• Tornadoes never form when there is rain, while hurricanes always form with rain.
• Tornadoes form under low pressure, while hurricanes form under high pressure
• Tornadoes form in a stable atmosphere, while hurricanes form in an unstable atmosphere 
• Tornadoes form over land, while hurricanes form over bodies of water

Which of the following is NOT TRUE about the water cycle?

• Water is heated by energy from the Sun
• The temperature of water vapor increases as it rises from the Earth's surface
• Water droplets get pulled to the Earth by gravity.
• The water cycle involves the heating and cooling of water in different states

A front is

• the center of a hurricane

• the amount of moisture in the air

• an area that has high winds

• a place where two air masses meet
