Question

Which among the following statements validate the fact that unequal distribution of land and water on Earth’s surface affects ocean temperature?

• A. Oceans in the northern hemisphere have relatively higher temperature.
• B. Water is a better conductor of heat than solids and thus, water heats up faster than land.
• C. The southern hemisphere has lesser amount of land in contact with water.
• D. The average temperature in equatorial areas is around 25° C

Answer 1

Answer: (A), (C)

The southern hemisphere has lesser amount of land in contact with water.

The unequal distribution of land and water on the Earth’s surface affects the ocean temperature. As land heats up faster than water, the temperature of water increases when it comes in contact with land. The northern hemisphere has more land area when compared to the southern hemisphere. Thus, the amount of land in contact with water is relatively higher. Therefore, the oceans in the northern hemisphere have higher temperature than the oceans in the southern hemisphere.
