Which layer of gas molecules in the atmosphere is bombarded with rays from the sun

How will the system respond to a temperature increase?

When the magnetic domains in a material can be aligned, but eventually drift out of alignment, the material is

Global warming will produce rising sea levels partly due to melting ice caps but also due to the expansion of water as average ocean temperatures rise. to get some idea of the size of this effect, calculate the change in length of a column of water 1.00 km high for a temperature increase of 1.00ºc. note that this calculation is only approximate because ocean warming is not uniform with depth. (answer in ×10^{-3} −3 m)
