Sci 8 Unit E Currents and Climates

Ocean currents are moving streams of water within the ocean. There are two types of currents – surface and deep. What differentiates between these two currents?

• A. Deep currents consist of colder, denser water.

• B. Surface currents consist of colder, denser water.

• C. Deep currents are more affected by the gravitational pull of the moon.

• D. Surface currents are more affected by the gravitational pull of the moon.

Why does Scotland and Labrador, although similar in distance from the equator, have such different climates?

• a) They have different latitude

• b) Labrador has an ocean current that brings warmer water from the equator to its location, whereas Scotland has an ocean current bringing colder water from the arctic.

• c) Scotland has an ocean current that brings warmer water from the equator to its location, whereas Labrador has an ocean current bringing colder water from the arctic.

• d) One of the locations is closer to the ocean than the other location, thereby stabilizing the temperature of the area to have a very mild climate.
