Question 1 (1 point) Saved
Differences in ocean water density are larger at low latitudes near the equator because the water temperature changes often throughout the year

Question 1 options:
True
False
Question 2 (1 point)
Salinity affects density. Choose all of the correct answers.

Lesson 2.08

Question 2 options:

As concentration of salt decreases, water density also increases.

As water temperature increases, water density increases.

As water temperature decreases, water density increases.

As concentration of salt increases, water density also increases.

Question 3 (1 point)
Saved
Ocean water density varies more at the the poles throughout the year than at the equator.

Movement of Ocean water

Choose ALL that apply

Lesson 2.08

Question 4 options:

Differences in the density of seawater cause it to move.

This water sinks and moves toward the equator where it replaces less dense, warm water.

Surface water at the poles is dense because of low temperatures and high salinity.

Saved
What are the main factors that affect an ocean current?

Lesson 2.09

Question 5 options:

geographical features

none of the choices

Wind caused by unequal heating of the earth

Coriolis effect

Question 6 (1 point)
Saved
How does Earth's rotation affect wind and ocean current patterns?

Lesson 2.09

Question 6 options:

none of the choices

all of the choices

The rotation of the earth causes the Coriolis effect, which results in wind and ocean currents having a curved shape

The rotation doesn't affect wind and ocean current

Question 7 (1 point)
Wind patterns are impacted by which of the following?

Choose ALL that apply

lesson 2.09

Question 7 options:

As a result, air near the equator heats up and rises because it is less dense.

Radiant energy from the sun strikes Earth unevenly.

The sun's energy heats air at the equator more than it does at the poles.

As it rises, it cools and begins to flow toward the poles. As this air leaves the equator, cooler and heavier air from the poles flows along the surface to take its place.

Question 8 (1 point)
Saved
The Coriolis effect is the deflection of winds to the right in the Northern Hemisphere and to the left in the Southern Hemisphere because of Earth’s rotation.

Question 8 options:
True
False
Question 9 (1 point)
How does Earth's rotation affect ocean currents?

Lesson 2.09

Question 9 options:

It causes them to flow from east to west

It causes them to flow from north to south

It has no affect

It causes them to flow in a curved path

Question 10 (1 point)
Most of the currents identified have a circular shape. This is because as the air and water move between the equator to the poles, they are also affected by the Coriolis effect, which makes them follow a more circular path.
