GEOG 2HI3 Lecture Notes - Lecture 1: Ozone Layer, Thermosphere, Solar Wind
Document Summary
Layers of life sustaining gases some formed over a billion years ago. Some are cushier components and other gases protect us from the direct uv radiation. Sunspots are cooler areas on the surface of the sun, on the sun"s photosphere, reduced surface temperature due to concentration of magnetic fields flux that inhibit convection. The coronal mass ejection is a significant release of plasma and accompanying magnetic fields from the solar corona. We can also describe coronal mass ejection as the explosion of plasma and magnetic fields from the suns corona. They can eject billions of tons of corona material and carry an embedded magnetic field that is stronger than the background solar wind. Temperature in thermosphere can be as high as 1200 degree celsius or 2200f. Vibration of molecules (kinetic energy) is temperature but the actual heat involved is small because the density of molecules is low in the thermosphere.
