Without a hot inner earth, convection would cease. With cessation of convection inside the earth, tectonic plate movement and subduction would cease. More importantly, we would lose our magnetosphere, which would leave us vulnerable to solar winds and other cosmic radiation. We would then be stripped of our atmosphere piece by piece, making us further vulnerable to cosmic radiation not to mention all the other ill effects of having little to no atmosphere (e.g. loss of breathable air, loss of greenhouse effect that keeps the temperature habitable, etc). In short, all life would die, and the planet would resemble other dead worlds like Mars or the Moon, who long ago had geological activity rising from interior convection.

Hope this helps

Online translators aren't so great, so I wouldn't try to do it that way. If this is homework that would pretty much guarantee you a low grade, your teacher would realize in a minute you did it online.
