Give reason:As we move upward from the sea-level, temperature of the air decreases.

Answer»
  • The earth’s surface gets heat from the Sun.
  • Thus, the surface gets heated.
  • The air close to the earth surface starts becoming hot.
  • Later, different layers of air at higher elevation receive heat.
  • Therefore, as we move upward from sea-level, the temperature of air decreases.
