What change occurs as deep ocean water becomes colder?
A. it becomes saltier
B. it becomes denser
C. it becomes clearer
D. it becomes lighter
Answer (1)
As deep ocean water becomes colder, it becomes denser due to the slowing movement of molecules. This increased density causes the colder water to sink below warmer water, which is essential for ocean circulation and climate regulation. Overall, colder temperatures lead to a decrease in volume and an increase in density. ;
