Question

Differences in water temperature in the ocean create movement because

Answer 1

Oceanic movements are driven by differences in water temperature due to convection, the Coriolis effect, and water's high heat capacity.

Step-by-step explanation:

Differences in water temperature in the ocean create movement because of the phenomena known as convection, the Coriolis effect, and the varying capacity of water to store heat. Warm water, which is less dense, rises while cooler water sinks, creating a convection current that contributes to the movement of water. Also significant is the Coriolis effect, which is the deflection of moving objects when viewed in a rotating reference frame, such as the rotation of the Earth; this affects both atmospheric and oceanic circulation patterns. Lastly, because water has a high specific heat capacity, it can store a substantial amount of heat, which affects how the ocean absorbs and releases heat and thus influences patterns of movement within the ocean.

Answer 2

This water movement is driven by convection: The movement of water due to differences in temperature. Because the warm water is lighter than the cold water and wants to expand, it moves into the upper cup through the hole.
