How much solar energy Earth receives is affected by the shape of it's orbit. Explain how circular and elliptical orbit might change earth's climate.
When Earth's orbit is more circular, Earth averages a greater distance from the sun, resulting in lower temperatures.
When Earth's orbit is more elliptical it experiences more seasonal variations, with warmer summers and colder winters.
