In this term paper we will consider the broad scale circulation of the atmosphere, which acts as a gigantic heat engine. The atmosphere is heated by the Sun-warmed surfaces in the equatorial regions and is cooled by radiation in the polar-regions. Heat is transported from the equatorial regions to the polar-regions by the primary circulation […]

The Earth’s climate is a solar powered system. Globally, over the course of the year, the Earth system—land surfaces, oceans, and atmosphere—absorbs an average of about 240 watts of solar power per square meter (one watt is one joule of energy every second). The absorbed sunlight drives photosynthesis, fuels evaporation, melts snow and ice, and […]
Weathering of Rocks: 3 Processes | Earth | Solar System | Geography
Article shared by : 
Process of weathering may be divided into three parts: 1. Physical Weathering 2. Chemical Weathering 3. Biological Weathering. Process # 1. Physical Weathering: In this type of weathering rocks are divided/disintegrated into different parts without any chemical change that is why it is known as mechanical weathering. Three agents work on this type of activity: […]
