Question

1. which of the following is the main source of energy for earths systems? (a) geothermal energy (b) nuclear energy (c) solar energy (d) wind energy

Explanation:

Solar energy is the primary source of energy for Earth's systems. It drives processes like weather patterns, plant photosynthesis (which forms the base of the food chain), and the water cycle. Geothermal energy is from the Earth's interior but is not the main source for overall Earth systems. Nuclear energy (in terms of natural sources relevant here) is not the main driver. Wind energy is actually a result of solar - heating - induced temperature differences in the atmosphere.

Answer:

C. Solar Energy
