Overview

The Sun is the primary source of energy for Earth. The energy received from the Sun in the form of short waves is called insolation. This energy heats the Earth's surface, which in turn warms the atmosphere. The distribution of temperature across the globe is not uniform and varies both horizontally

Key Concepts

Insolation refers to the incoming solar

Insolation refers to the incoming solar radiation received by the Earth in the form of short waves. It is the primary source of heat and energy for Ea

The heat budget is the balance

The heat budget is the balance between the amount of solar radiation received by the Earth (insolation) and the amount of heat radiated back into spac

Global warming is the gradual increase

Global warming is the gradual increase in Earth's average atmospheric temperature due to increased greenhouse gases like carbon dioxide and depletion

The variation of temperature across latitudes

The variation of temperature across latitudes and regions on Earth’s surface, influenced by factors like latitude, land-sea contrast, ocean currents,

The change in temperature with altitude

The change in temperature with altitude in the atmosphere. Normally, temperature decreases with height at a rate of about 6°C per 1000 meters, known a
