What is the temperature of the water at a cold seep? A.
around 4°C
B.
around 20°C
C.
always below the freezing point of water
D.
hot, but much cooler than at a hydrothermal vent

D. hot, but much cooler than at a hydrothermal vent

Explanation:

A cold seep is an area in the ocean floor where hydrogen sulfide, methane and other hydrocarbon rich fluids seep through thus forming a brine pool.

A cold seep is also called a cold vent and its temperature is not necessary lower than that of the surrounding water, but it is lower than that of a hydrothermal vent which is about 60 °C.

the speed increase from w to x due to increased gravity force

the speed decreases from x to y due to decrease in gravity

it would affect precipitation by causing flooding in some areas of the world due to climate increasing, causing the glaciers in the northern and southern pole of our planet to melt.

i wish you would have provided choices to simplify it and allow me to give an exact answer.
