It is due to the difference in specific heat between two substances. In our weather, the two substances we are referring to are land and water. The specific heat of water is higher than any other common substance on Earth. In other words it takes a lot of energy to heat water.

Answer:

Step-by-step explanation:

Well put simply, all our beautiful lakes this time of year are cold after a long winter. If you are enjoying a nice sunny, warm calm day, then the temperature drops 20 degrees as a breeze swings in from the lake, we call that a lake breeze. You can blame the specific heat as to why that occurs. Specific heat is defined by the amount of energy required to raise a unit of mass of a substance by a degree. For our purposes it is how much heat energy it takes to raise the same amount of water as it does land.
