Suppose the Earth is really flat. Shaped like a penny, it has one side that faces the Sun at all times. Suppose this Earth is the same temperature everywhere (including the side that faces away from the Sun). Neglect any radiation losses off the rim of the Earth and assume there is no albedo and greenhouse effect. Treating it as a perfect blackbody, estimate the temperature of this new, flat Earth

Using the equation to calculate flat earth temperature

T = [ S / 2σ] ∧1/4

2σ is considered for one side of face of earth

S is solar constant

T = [ 1370 / 2 * 5.67 * 10 ∧ -8] ∧1/4

= 331.53 K.

Explanation:

The correct answer to the given question is explained below,

The temperature of the earth would be high if the earth was flat instead of being sphere.

Using the equation to calculate flat earth temperature

T = [ S / 2σ] ∧1/4

2σ is considered for one side of face of earth

S is solar constant

T = [ 1370 / 2 * 5.67 * 10 ∧ -8] ∧1/4

= 331.53 K.
