Water variations in the ocean-salinity

Question 1

What is salinity?

Answer 1

The measurement of salt content in the water

Question 2

What is salinity like near equator?

Answer 2

Low because, lots of rain

Question 3

What are 5 reasons why salinity varies?

Answer 3

-evaporation
-precipitation
-rivers
-winds
-ice formation

Question 4

How does evaporation affect salinity?

Answer 4

Higher rates of evaporation, higher salinity as water molecules are evaporated leaving high distribution of salt

Question 5

How do rivers affect salinity?

Answer 5

Rivers push fresh water into the sea, lowering salinity

Question 6

How does precipitation affect salinity?

Answer 6

Adding fresh water so lower concentration of salt

Question 7

How do winds affect salinity?

Answer 7

Blows sand into water, increasing salt concentration
Wind can also blow fresh water into sea, decreasing salinity

Question 8

How does ice formation affect salinity?

Answer 8

When water freezes and turns to ice, the salt is left behind

Question 9

What does halocline mean?

Answer 9

The idea that salinity also varies with depth

Question 10

What happens to salinity as depth increases?

Answer 10

salinity increases
