Mesothermal

Hi there! So, mesothermal refers to areas where the temperature of the Earth's crust is somewhere in the middle - it's not too hot and it's not too cool.

Let's imagine you have a pot of water on the stove. If you turn the heat up all the way, the water will eventually start boiling and become very hot. If you turn the heat down really low, the water will stay cool or maybe just get a little warmer.

Now, let's think about the Earth's crust. In some places, the temperatures are really high - like if you were to put a pot of water on a volcano. In those places, the rocks and earth can become super hot and even melt!

In other places, the temperatures are really low, like if you were to put your pot of water in the fridge. In those places, the rocks and earth stay pretty cool.

But in mesothermal areas, the temperatures are in the middle - like if you were to put a pot of water on a stove at medium heat. The rocks and earth there are not too hot and not too cold, and that makes those areas really interesting for geologists and scientists to study.

So that's what mesothermal means - it's a fancy science word that describes areas of the Earth's crust where the temperature is just right, like Goldilocks's porridge.
