Did you know that the mesopause is the coldest part of the atmosphere?

Really? I didn't know that! What happens there?

It's the boundary where the temperature drops to its lowest point before reaching the thermosphere.

That’s fascinating! I love learning about the layers of the atmosphere.

Root Explanation

Mesopause → It is formed from "meso-" (from Greek "mesos", meaning middle) and "pause" (from Latin "pausa", meaning a stop or break). The word "mesopause" refers to the middle layer of the atmosphere where temperatures stop decreasing and begin to increase, marking a transition point.

Memory Tip

Think of the 'middle' ('meso-') layer of the atmosphere where temperatures 'stop' ('pause') decreasing — that's what mesopause refers to.
