Weather Unit Test

Students perform an investigation to learn about convection. After the investigation, students record their notes in the table.

Which students correctly describe convection?

1-The warm water rises because it is less dense, the cool water sinks because it is denser.

2-The warm water sinks because it is denser, the cool water rises because it is less dense.

3- The flame is the heat source that drives convection currents.

4-Convection currents only occur in water

• Student 1 only

• Student 1 and 3 only

• Student 2 only

• Student 2 and 4 only

How do ocean currents impact weather patterns?

• A. Ocean currents transport water to areas that get small amounts of precipitation.

• B. Ocean currents trap thermal energy at the poles but not at the equator.

• C. Ocean currents circulate warm and cold water around Earth.

• D. Ocean currents create fog by cooling the surrounding air.

How do interactions between the sun, atmosphere, and hydrosphere impact weather patterns? Select TWO correct answers.

• A. The atmosphere and the hydrosphere both absorb thermal energy from the sun.

• B. The atmosphere absorbs thermal energy from the sun, but the hydrosphere reflects thermal energy from the sun.

• C. The atmosphere and the hydrosphere release thermal energy into space, reducing atmospheric temperatures.

• D. Water molecules evaporate from the hydrosphere into the atmosphere, causing condensation, cloud formation, and precipitation.

• E. Water molecules evaporate from the atmosphere into the hydrosphere, causing condensation, cloud formation, and precipitation.

Which statement about wind formation is correct?

• Wind forms when air moves from areas of high pressure to areas of low pressure.

• Wind forms when air moves from areas of low pressure to areas of high pressure.

• Wind forms when clouds move across the sky, which stirs the air below.

• Wind forms when water evaporates from the ground, which causes air to move.

Four students described low-pressure weather systems. Their descriptions are shown below.

Which students correctly described low-pressure systems?

1 In low-pressure systems, the air is cold and more dense.

2 In low-pressure systems, the air is warm and less dense.

3 Low-pressure systems lead to cloudy conditions and precipitation.

4 Low-pressure systems lead to sunny, clear, and calm conditions.

• A. Student 1 and Student 3

• B. Student 1 and Student 4

• C. Student 2 and Student 3

• D. Student 2 and Student 4

Which statement correctly describes an air mass?

• An air mass is an area where two weather fronts meet and do not mix.

• An air mass is a large volume of air that is uniform in temperature and humidity.

• An air mass is an area where a large volume of cold air meets a large volume of warm air.

• An air mass is a large volume of air that is uniform in mass and volume.
