Weather Unit Exam Review!

How is hotter air different than colder air?

• Hotter air consists of different molecules than colder air.

• In hotter air, the molecules are closer together and move more slowly than in colder air.

• 
  In hotter air, the molecules are farther apart and move more rapidly than in colder air.

• Hot air is denser than colder air.

In electric ovens, the heat in the oven comes from the bottom when you bake something.  However, cookies baking on the top shelf get done before cookies on the bottom shelf, even though the bottom shelf is closer to the heat source.  This happens because heat _____

The sun heats the earth's surface and beneath the earth's surface, solar energy is being converted to thermal energy. Once the thermal energy has been converted in the surface, the heat transfers from earth's surface to the air molecules above the ground. What is this process called?

• convection

• conduction

• heating

• sweating

Which is an example of conduction?

• A hot slice of pizza burning your mouth

• heat rising

• water in a glass

• a high five

Ocean currents occur in each of Earth's oceans.  The diagram shows the temperature and currents on the East and West coasts of the United States.  Which statement best describes the temperature of the current?

• The current off the East coast of the United States is cold because it comes from the Arctic area (Labrador Current).

• The current off the East coast of the United States is cold because it comes from the Canary Current off the coast of Africa.

• The current off the East coast of the United States is warm because it comes from the N. Equatorial Current and the Gulf Stream.

• The current off the East coast of the United States is warm because it comes from the California Current.

Why do seasons happen?

• The tilt of the Earth on its axis causes the Earth to rotate at different angles, heating the Earth differently throughout the year, which causes the seasons.

• The revolution of the Earth around the Sun brings the Earth closer to and farther away from the Sun, causing the Earth to heat up and cool down during the different seasons.

• The tilt of the Earth on its axis causes the Sun to shine with different intensities on different parts of the Earth at different times of the year.

• The rotation of the Earth is affected by the Sun’s intensity on different parts of the Earth's surface at different times of the year.

June and December are different seasons in the Northern Hemisphere because of the Earth's tilt, the Northern Hemisphere tilts toward the Sun in ____ and away from the Sun in December.

Why do Northern and Southern hemispheres experience different seasons?

• The Sun moves up and down as the Earth revolves in its annual cycle. This causes it to be summer in the Northern Hemisphere and winter in the Southern Hemisphere in June

• 
  In December, the Sun's rays are spread out more over the Northern Hemisphere while they hit the Southern Hemisphere more directly. This causes it to be winter in the Southern Hemisphere and summer in the Northern Hemisphere in December.

• 
  In June, the Sun's rays are spread out more over the Southern Hemisphere while they hit the Northern Hemisphere more directly.  This causes it to be summer in the Northern Hemisphere and winter in the Southern Hemisphere in June.

• 
  In June, the Sun’s rays are spread out more over the Northern Hemisphere while they hit the Southern Hemisphere more directly. This causes it to be summer in the Northern Hemisphere and winter in the Southern Hemisphere in June.
