In fact the earth is round, sunlight does not reach everywhere equally. The temperature decreases as we move from the equator to the poles. Altitude: As we move from the surface of the earth to the higher altitudes, the temperature decreases. The temperature decreases as we move from the equator to the poles. Altitude: As we move from the surface of the earth to the higher altitudes, the temperature decreases. Pressure and wind system: The pressure and wind system of any area depend on the latitude and altitude of that place. Due to the curvature of the earth, the amount of solar energy received varies according, to latitude. As a result, air temperature' generally decreases from, the, equator towards the poles. Another climate control is altitude, or elevation. Just as there is a gradual decrease in average temperature with increasing latitude, there is a decrease in temperature with increasing elevation. India's climate relies upon its latitudinal degree. Tropic of Cancer isolates the country into two half. One is the tropical climate which lies south of the Tropic of cancer and another are the Subtropical climate which lies North of the Tropic of cancer.
