The characteristics of different rocks depend on the environment in which the sediments were deposited.
Some sands and gravels are dropped by glaciers as they melt and they become a distinctive rock called till.
Where till is found there must have been glaciers and therefore it must have been cold.
Rocks that form in a hot desert environment are often coloured red with iron deposits.
Also at high temperatures, sea water can evaporate quickly leaving behind a layer of salt on the ground which becomes preserved in the rocks and is another indicator of a hot climate.
