Student written questions

1. Typically, the salinity at the bottom of the ocean higher than the salinity at the surface.

2. Describe the reason for your answer above.

The surface of the ocean has as more an influx of freshwater (because of precipitation) than the bottom of the ocean. It also has a higher salinity because the more salt there is in water, the denser it becomes, which makes it sink to the bottom.

3. What is density?

Density is defined as the mass per unit of volume.

4. What is the name for the area of rapidly changing salinity?

The area of rapidly changing salinity is known was the thermoclines.

5. Where on Earth will you find a lower surface salinity?

and Europe temperate because of the movement of warm water to the coasts. Without the crucial current, the regions would experience much colder winters.

14. What direction does the Earth spin on its axis? It rotates west to east.

D) liquid water, solid ice, water vapor

16. Which of the following is NOT a characteristic of water:

A) it has a very high surface tension

B) is exists naturally as a gas, liquid, and solid on Earth 's surface

C) it is a polar molecule

D) it is more dense as a solid than as a liquid

17. In the northern hemisphere, the Coriolis effect causes objects to be deflected:

A) in the same direction as the southern hemisphere

B) to the west of their original direction.

C) to the east of their original direction.

D) to the right (clockwise) of their original direction.

E) to the left (counter-clockwise) of their original direction.

18. As the salinity of water increases, the density of the seawater
