Which of these changes does a submarine encounter as it returns from the bottom of the ocean to the surface of the ocean? a. the amount of sunlight increases. b. the water temperature decreases. c. the amount of plants decreases. d. the water pressure increases.

Answer

Correct option is a ( the amount of sunlight increases)

Explanation:

a. Sunlight does not penetrate the deep ocean it means at the bottom of ocean there is complete darkness. So when a submarine returns from the bottom of the ocean to the surface the amount of sunlight increases.

b.Usually temperature decreases with depth of ocean so this option is not correct.

c.This is also not correct option because on the surface of the ocean there may be island on which there may be lots of plants.

d. Pressure decreases on moving upward direction so this option is also not correct

i just did an experiment like this in my science class. also the answer is yes, it will get separated because they are two opposites meaning if they are opposite they can not attract.

hope this .!
