Explanation:

Understanding Ocean Currents and Solar Energy Absorption

The questions aim to explore the relationship between solar energy absorption by the ocean and the factors affecting ocean currents, which are essential in climate control and marine ecosystems. Let’s break each question and its correct options down:

  1. Which of the following absorb more solar energy? A. Ocean absorbs more energy – This is correct as oceans absorb about 70% of solar energy due to their vast surface area and properties, significantly influencing the Earth's climate.
  2. What are the three things that cause currents? A. Wind, gravity, water density – Currents are generated by these factors, with wind playing a crucial role in surface currents, while gravity and water density relate to deeper currents.
  3. How is ocean current generated? A. By forces acting upon the water including wind, the Coriolis effect and temperature configurations – This highlights key mechanisms, including wind which pushes surface currents, and the Coriolis effect that alters their direction.
  4. Horizontal movements of water are referred to as currents, while vertical changes are called: C. upwellings – This is correct, as upwellings are vertical movements bringing nutrient-rich water to the surface and directly impact marine biology.
  5. Majority of the sun's radiation is absorbed by the ocean by how many percent? B. 70 percent – Oceans are essential for the absorption of solar energy, approximately 70%, which plays a significant role in regulating climate.
  6. Which of the following currents is responsible for the climate in many parts of the world? D. Surface current – Surface currents, driven mainly by wind, have substantial effects on weather patterns and climates globally.
  7. Which of the following ocean currents is primarily responsible for the heat transfer from the equator to higher latitudes in the North Atlantic Ocean? C. The Gulf Stream – The Gulf Stream is well-known for transporting warm water from the tropics to Europe, significantly affecting the climate there.
  8. It is a current that forms near the poles and travels toward the equator creating a cooler climate near the coastlines it travels by: A. Cold ocean current – Cold currents influence local climates by cooling the area they pass through.
  9. This thermohaline circulation is also known as the ocean's conveyor belt. These currents are sometimes called: A. deep water rivers – This name reflects their role in transporting water globally.
  10. Which currents that cause by the differences in density of masses of water?: B. Deep water currents – These currents are driven by variations in water temperature and salinity, affecting density.
  11. Which factor is most responsible for the creation of the Antarctic Circumpolar Current (ACC)?: A. Wind patterns from the Southern Hemisphere and the absence of landmasses to interrupt the flow. – This current is unique due to the uninterrupted flow around Antarctica, driven by strong winds.
  12. As per Robinson Projection, which of the following is a warm water current?: B. Kuroshio current – The Kuroshio Current is a strong warm ocean current running northward along the eastern coast of Japan.
  13. Which of the following is NOT a major effect of currents?: C. Magnetic effect – Ocean currents primarily affect climate, dynamics, and chemical makeup, but do not have significant magnetic effects.
  14. Surface currents are determined by the following major factors EXCEPT:: B. The shape of ocean basins – While the shape of the ocean basins may influence currents, the wind patterns predominantly drive surface currents.

In summary, understanding how ocean currents work and their absorption of solar energy is crucial for predicting climate and weather patterns on Earth. These elements play significant roles in marine ecosystems, influencing both biomes and human activities around the globe.
