Question

1. The amount of incoming solar radiation absorbed at the Earth’s surface is approximately: a. 90% b. 70% c. 50% d. 30% e. 10%

2. True/False: During the nighttime, the atmosphere will cool via the process of radiation faster than the surface of the earth: a. True b. False

Answer 1

Radiation absorbed at the Earth’s surface is b. 70%. 2. a. True

Step-by-step explanation:

• The point of incoming solar radiation received a the surface is 100 % but the amount of energy that is reflected clouds and gases in atmosphere make up to 23% hence this along with the 48% of incoming solar energy at the earth surface features creates a total net of 71% being taken up by the earth's land surfaces.

• As this radiation which is given by the sun comes in the form of an incoming shirt wave from the earth radiate as a black body with long-range radiation that transfers the earth heat to outer space hence we experience cool mornings.

• Due to radiative cooling which is the process of heat loss through the thermal exchange.
