Solar Energy

Energy from the sun is called ..................

• Geothermal

• Solar

• Hydroelectric

Some energy is absorbed by land, water, and the atmosphere and some energy is reflected back to space.

• Yes

• No

The amount of solar radiation reaching the earth surface is called

• Insolation

• Solar constant

• Air mass

The total radiation energy received from the Sun on a surface perpendicular to the Sun’s rays outside the atmosphere

• Global insolation

• Solar constant

• Air mass

Measure of how much atmosphere the sun's rays have to pass through on their way to the surface of the earth.

• Air Mass

• Insolation

• Solar Energy

Sum of direct, diffuse and reflected light is called

• Global insolation

• Air Mass

• Solar radiation

The sunlight that has been scattered by molecules and particles in the atmosphere

• direct radiation

• diffuse radiation

• reflected radiation

Three layers of solar pond are

• Surface Convectice Zone, Non- Convectice Zone,Lower Convective zone

• Upper salt layer, middle salt layer, lower salt layer

• Surface Non-Convectice Zone, Convectice Zone,Lower Non-Convective zone

Layer in which concentration and temperature increase with depth in solar pond

• Surface Convectice Zone

• Non- Convectice Zone

• Lower Convective zone

The value of solar constant is approximately ...........
