Question

1. Describe the differences between radiation, conduction, and convection.

Answer 1

1. Radiation - energy transmits through particles that ionize. Conduction - heat is transferred through a substance without moving the material. Convection - transfer of heat through movement.

2. Earth receives energy from the sun, which is transferred between Earth and its atmosphere.

3.Wildland fires, dust storms, and volcanic activity. They release CO2, CH4, N20, and sulfur dioxide.

4. Burning coal, releases carbon dioxide and other pollutants. Gasoline, releases air pollution. Factories, releases carbon dioxide, methane, and nitrous oxide.

Answer 2

Explanation:

1. Conduction : When two bodies are in direct contact, the heat transfer is said to be taken place by conduction.  

Convection :  Conduction is the heat transfer which takes place by actual motion of matter.          

Radiation :  Radiation is the heat transfer with the help of electromagnetic waves.

2. The earth receives heat from the sun by radiations. This heat is taken up by the earth and is radiated back to the atmosphere.

3. Changes in the earth's orbit around the sun, changes in the axis of rotation and change sin ocean currents are three natural factors that affect earth's climate.

4. Emission of green houses gases to the atmosphere, deforestation, polluting the water bodies are three man made factors that affect earth's climate.
