Question

why are some parts of the ocean water cold, while some nearby parts are warmer?
o because warm water is more dense than cold water
o because cold water is more dense than warm water
o because warm water holds more oxygen than cold water
o because cold water holds more oxygen than warm water

Explanation:

Step1: Analyze the solubility of oxygen in water

The solubility of gases in liquids generally decreases with increasing temperature. Cold water can hold more oxygen than warm water.

Step2: Analyze the density of water

Cold water is more dense than warm water. As temperature increases, water molecules gain kinetic energy and move more, causing the water to expand and become less dense.

Answer:

Because cold water holds more oxygen than warm water.
