How is temperature different in different bottom types and zones?

Mud temp more stable than rock. Wtaer gets trapped in interstital space. Sediment: A lot of species in the sediment will try to live in a certain depth. Still connected to surface but in more stable environment. Rocky intertidal. Rocky intertidal: Almost 30 degress difference in no time. 20 degree dif between no cannopee and under cannopee. Very stresfull. Intertidal:In summer water temp is lower than air temp. Winter water is higher than air. Those at the intertidal fase the strongest viariation in temp. Desication (dry out) is the biggest problem in upper intertidal.
