49.                  are the horizontal movement of water at or near the ocean’s surface. Deep Currents Global Winds Surface Currents Upwelling

The correct answer is Surface Currents.

Explanation:

Surface currents are horizontal movements of water that occur at or near the ocean's surface. These currents are primarily driven by global winds and are influenced by factors such as the Earth's rotation (Coriolis effect), the position of continents, and variations in water temperature and salinity. Surface currents play a crucial role in regulating climate and weather patterns by redistributing heat from the equator towards the poles.

Context:

• Global Winds: While they drive surface currents, they are not movements of water themselves.
• Deep Currents: These are primarily driven by differences in water density and occur at greater depths in the ocean.
• Upwelling: Refers to the process where deep, cold, nutrient-rich water rises to the surface, but it is not a horizontal movement.

Thus, in the context of horizontal movements of water at or near the surface, Surface Currents is the most appropriate choice.
