5.3-The Hydrosphere - 5

What is salinity?

• The temperature of water

• The total amount of dissolved salt in water

• The depth of water

• The distance from the surface to the bottom of the ocean

How is temperature defined?

• The distance between objects

• The hotness and coldness of an object

• The total amount of dissolved salt in water

• The pressure exerted by water

What does depth refer to?

• The total amount of dissolved salt in water

• The hotness and coldness of an object

• The distance from the surface to the bottom

• The pressure exerted by water

How does salinity change with evaporation?

• It decreases

• It remains constant

• It increases

• It disappears

Salinity near poles is more due to:

• More rainfall

• More glaciers

• More evaporation

• More river inflow

How does salinity affect the freezing point of water?

• It increases the freezing point

• It decreases the freezing point

• It has no effect on the freezing point

• It causes the water to evaporate

How does salinity impact the density of water?

• It decreases water density

• It has no impact on water density

• It increases water density

• It turns water into gas

What is the average depth of the ocean?

• 1 kilometer

• 2 kilometers

• 3 kilometers

• 4 kilometers

What happens to pressure as you go deeper into the ocean?

• It decreases

• It remains constant

• It increases

• It disappears

What happens to temperature as you go deeper into the ocean?

• It increases

• It remains constant

• It decreases

• It disappears
