1. how is pressure affected as depth increases?

2. as the sun heats the surface of the oceans, two layers of water result. what separates the layers?

3. how is temperature affected when?
(a) the depth increases
(b) the latitude increases

4. how is salinity affected?
(a) evaporation increases
(b) freezing increases
(c) melting increases
(d) precipitation increases

5. how is density affected when?
(a) the temperature increases
(b) the depth increases
(c) the latitude increases
(d) the salinity increases

6. where does the energy that causes evaporation come from?

7. what role does gravity play in the water cycle?

8. describe the flow of one molecule of water through the water cycle, beginning in the ocean.

The pressure is increased as depth increases.

The temperature of water of these layers separate the water layers in the ocean.

The ocean gets the heat energy from the sun. The temperature of ocean increase as it gets energy from the sun.

But heat distribution is not uniform.

As we know hot fluids tend to be stay on the top.

So the upper layer will get more heat and stay on the top.

The warm water from the sun do not circulate in the water, so the layer under that warm layer will be relatively colder.

The temperature will increase with the increase in depth.

The temperature decreases with the increase in altitude.

both adhesion and cohesion are attractions.

they are different in that adhesion is the force of attraction between the molecules of two different substances, whereas cohesion is the force of attraction between molecules of the same substance.

possible examples include capillary action, in which the adhesion between water and glass causes the water to rise in a narrow tube against the force of gravity.

because of hydrogen bonding, water is extremely cohesive.

this causes molecules on the surface of water to be drawn inward, which is why drops of water form beads on smooth surfaces.

hope this .
