Question
What resource does Earth receive directly from outside the
planet rather than from natural resources?Solution
Energy, particularly solar energy from the Sun, is the only resource listed that comes directly from outside Earth rather than from the planet's natural resources. The Sun provides solar radiation that powers life on Earth, supports photosynthesis in plants, and drives weather patterns, ocean currents, and the water cycle. Other forms of energy from space include cosmic radiation, though it's not harnessed as efficiently as solar energy. In contrast, minerals, coal, and natural gases are all extracted from within Earth's crust.
