30 points 4 questions marine science
1. all of the following are true of surface currents except
a. influenced by wind
b. exist in large lakes
c. are found in the top 1,300 feet of the ocean
d. have the same movement as thermohaline currents
2. a water molecule's shape resembles which of the following?
a. oval
b. circle
c. square
d. triangle
3. much of the earth's heat is retained in the
a. crust
b. wind
c. oceans
d. mountains
4. most hurricanes will originate
a. near the north pole
b. in the equatorial region
c. when the water and air are cold
d. below the ocean's surface current

Option D is correct.

d. have the same movement as thermohaline currents

The movement of the surface water of the ocean due to the certain pattern of wind and Coriolis Effect and earth spin creates surface currents. That are influenced by all of the above three except the fourth one.

Option D is correct.

d. triangle

Water molecules are not linear in shape. Oxygen has 8 electrons in its valence shell so there are two bonding pairs in water and two lone pairs. Lone pairs strongly repel each and water molecules get bent shape due to this.

Option C is correct.

c. oceans

We just do not know that how much heat is captured in the oceans. Most of the heat dissipates in the atmosphere is absorbed in the oceans. So, most of the heat is retained in oceans.

Option B is correct.

b. in the equatorial region

Hurricanes begin as the warms storms in tropical regions of due to the warm moist water of Atlantic and Pacific Oceans near the equator. So the correct option is B.
