Exosphere is the last layer of atmosphere which is present at the height 700 to 10000 km from earth surface. This layer is thin as compared to other layers of the atmosphere. The layer of exosphere is composed of two elements i. e. helium and hydrogen. The temperature of exosphere is 1700 degree Celsius at daytime and becomes cold at night.
