Geography

Distribution of temperature and inversion of temperature

This Class 11 Geography topic explains how temperature varies across the Earth’s surface and through the atmosphere as part of solar radiation, heat balance, and temperature studies. Students learn about horizontal and vertical temperature distribution, the normal decrease of temperature with altitude, and the factors that influence it, including latitude, land and water, ocean currents, winds, and relief. The topic also examines temperature inversion, its causes, types, and effects on air movement, fog, pollution, and local weather conditions.
