Unit 7 Test

The Coriolis effect is the curving of the path of a moving object in Earth's atmosphere that is caused by Earth's rotation. How does the Coriolis effect affect winds globally?

• It causes the air to move as wind.

• It causes the winds to shift north and south.

• It causes wind to blow from any direction.

• It causes an apparent change in wind direction.

Vivian placed an ice cub in a tray of warm water. What statement describes the energy transfer that happens in Vivian's investigation between the ice cube and warm water?

• Energy in the form of heat is transferred from the ice cube to the water by radiation.

• Energy in the form of heat is transferred from the water to the ice cube by radiation.

• Energy in the form of heat is transferred from the ice cube to the water by conduction.

• Energy in the form of heat is transferred from the water to the ice cube by conduction.

Cindi's teacher gives her a map of the world. On her map, Cindi draws lines with arrows to show some of the major surface currents in the oceans. Her map looks similar to the map below. What conclusion about Earth's surface currents could someone draw by looking at Cindi's map? (counterclockwise=to the left)

• Surface currents in the Eastern Hemisphere flow in a counterclockwise direction.

• Surface currents in the Western Hemisphere flow in a counterclockwise direction.

• Surface currents in the Southern Hemisphere flow in a counterclockwise direction.

• Surface currents in the Northern Hemisphere flow in a counterclockwise direction.

How does salinity change with temperature?

• as water cools, it contracts and becomes more salty

• as water cools, it expands and becomes less salty

• as water warms, it contracts and becomes less salty

• as water warms, it expands and becomes more salty
