Why does the thermosphere have the highest temperature of all the atmosphere layers
🔄 Click to see definition
Definition1/12
The thermosphere is the first layer of the atmosphere where there are enough heavier molecules (oxygen) to absorb a significant anount of the Sun's radiation. Below the thermosphere, much of the heat is dissipated by convective currents. Although technically "hot", the gas in the thermosphere is so thin that it can pass little heat to other molecules, and loss of heat by radiation would still cool objects in this part of the atmosphere. the sun's radiation strikes it first

When a star explodes, it is referred to as a nova. If the star
is large enough, it will create a super nova. And if the star is
dense enough, it does not explode, but instead collapses on itself
and forms a black hole

Terrestrial means on Earth so Earth is the only terrestrial
planet
This is incorrect, the first 4 planets are terrestrial as they
are solidly bound planets. Pluto was also a terrestrial dwarf
planet. Any planet can have moons but due to the gas giants having
larger gravitational forces they have traditionally gathered more
moons. Thusly, no.
