the diagram is a view of a table that you are looking down on, the dark gray blocks are hanging off the side of the table pulling on the block in the middle.

choose a direction the block will move by using the letters a to h going around the table.

explain why you think it will move that direction:

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)
