A rift valley only happens when the plates are diverging. A trench represents plates converging. And the presence of active volcanoes is only on converging and some diverging boundaries (hence there is no volcanoes in California). An earthquake is present in all plate boundaries.
1. It spreads with a greater volume and less concentration of elements.
Its temperature stays well below the 14 million Kelvin.
It has hydrogen atoms that retain there electrons.
2. Its volume shrinks and the density increase die to the gravity
Its temperature stays above the 14 million kelvin
Hydrogen atoms shed there electron.
Explanation:
As the star is born within the clouds of dust and is scattered throughout most galaxies. The Orion Nebula is shown in the image that has a turbulence layer of clouds made of gases. These clouds tend to have temperatures of 100 Kelvin thus commonly called the HI clouds.
