Question

Seasonal variations on Earth occur due to its

• A. tilted axis
• B. rotation around its own axis
• C. revolution around sun
• D. both (a) and (c)

Answer 1

Answer: (D)

both (a) and (c)

The revolution of our planet around the Sun and the tilt of axis cause annual variations in the intensity and duration of temperature, resulting in distinct seasons. These variations together with annual variation in precipitation account for the formation of major biomes such as desert, rain forest, and tundra.

So the correct option is 'both (a), and (c)'.
