An object in emits radiation at the same rate it absorbs solar energy.

An object in black emits radiation at the same rate it absorbs solar energy

Explanation:

All body emits radiation following their temperature. E.g. colder bodies emit radiations with a longer wavelength, while the hot bodies emit radiation with short wavelength and higher frequencies.

A black body can be considered as an ideal body that absorbs all the energy incident on it and then emits all the radiation absorbed in a continuous spectrum depending on its temperature. In nature, stars behave similarly to black bodies. They emit all the radiation in a continuous spectrum depending on temperature. E.g. Cooler stars emit wavelength in the red and infra spectrum, while high-temperature stars emit lights in blue and UV wavelength

explanation:

plate tectonics and volcanic euptions

over time, plate tectonic processes cause continents to move to different positions on the globe.

for example, britain was near to the equator 300 million years ago, and therefore was hotter than it is today. for further details look at our climate through time poster or online map.

the movement of the plates also causes volcanoes and mountains to form and these too can contribute to a change in climate.

mountain ranges formed by plate tectonics. large mountain chains can influence the circulation of air around the globe, and consequently influence the climate.   warm air might be deflected somewhere cooler by the mountains.
