Earth's Energy Balance and Green House Effect

Earth's Energy Balance and Green House Effect

The Earth gets all its energy from the Sun. The amount of energy the Earth receives from the Sun is balanced by the amount it loses to space. An increase in the concentration of greenhouse gases affects the Sun - Earth energy balance and causes...Show More
Expansion in Gases

Expansion in Gases

Gases expand on heating and contract on cooling. Gases expand much more than solids and liquids.
Expansion in Liquids

Expansion in Liquids

Liquids expand on heating and contract on cooling. Different liquids expand by different amounts for the same rise in temperature. Liquids expand more than solids and less than gases.

Ways of Heat Production: Burning of Fossil Fuels

Fossil fuels provide us energy for activities like cooking, running vehicles, generating electricity, and as industrial feedstock. Some of the main fossil fuels are coal, petroleum oil, and natural gas.
Ways of Heat Production: Solar Energy

Ways of Heat Production: Solar Energy

Heat energy is widely used in households, commercial buildings, and industries. The sun gives us energy in the form of heat and light. This is also called solar energy and is is available through both active and passive solar heating.
