Answer 2

high temperatures and low gravity
low temperatures and low gravity
low temperatures and high gravity
high temperatures and high gravity

Answer 3

The exosphere is considered to have high temperature and low gravity because the individual gas molecules of which it is composed are moving fast. However there are very few of them and any solid object in the exosphere will have high temperatures in sunlight and low temperatures in the shade. Gravity is lower than on the surface of the earth. Gravity is inversely proportional to the square of the distance - so an object at 3,500 mile altitude will only feel one quarter of the pull of the same object on the surface.
