Thermosphere

Hello there! A thermosphere is a very high-up layer of Earth's atmosphere. Do you know what the atmosphere is? It's an invisible layer of gas that surrounds our planet and it helps protect us from the sun's harmful radiation.

The thermosphere starts about 56 miles above the Earth's surface and goes up to about 620 miles high. That's way up in the sky! In fact, the International Space Station orbits in the thermosphere.

Now, at this height, temperatures can get really hot- up to 4000 degrees Fahrenheit! But wait, why is it so hot when it's so high up in the sky? That's because the thermosphere is exposed to a lot of radiation from the sun. This energy heats up the gas particles in the atmosphere, making the thermosphere really hot.

There's another interesting thing that happens in the thermosphere. This layer is home to the auroras (Northern lights and Southern lights), which are beautiful and colorful displays of light in the sky. These lights happen when particles from the sun collide with particles in the thermosphere and make the air glow.

Overall, the thermosphere is a really important layer of Earth's atmosphere that helps protect us from the sun's radiation and is also home to the beautiful auroras.
