Solar Radiation and Heat Balance Quiz

Solar Radiation

• The energy received by the earth from the sun is called solar radiation.
• The earth intercepts a very small portion of the sun's total energy output.
• The sun is the main source of energy for the earth.

Atmospheric Pressure and Wind

• Pressure differences in the atmosphere are caused by the uneven heating of the earth's surface.
• The motion of air is called wind.
• Wind results from the movement of air from high-pressure areas to low-pressure areas.

Earth's Shape and Climate

• The earth's shape, resembling a sphere, is referred to as a geoid.
• The heating and cooling of the atmosphere and the resultant temperature distribution over the earth's surface is called climate.

Earth's Energy Balance

• The earth receives an average of 1.94 calories per square centimeter per minute from the sun at the top of its atmosphere.
• The energy received by the earth in short wavelengths is called insolation.
• The transfer of heat from one region to the other by winds is a crucial factor in maintaining the earth's energy balance.

Earth's Surroundings

• The earth is surrounded by the atmosphere all around.
