If we will base our answer on Hertzsprung diagram, we will see that mass and luminosity are directly related, which means, long lived stars begin their lives with more mass and a larger amount of hydrogen fuel, hence hydrogen is abundant before than now. They are more luminous during their main sequence lives. Giant stars and supergiant stars have great masses, so, they have greater luminosities.

Give me 5 facts about exogenic processes

Nina [5.8K]

$\LARGE{ \underline{ \underline{ \red{ \bf{Exogenic \: processes:}}}}}$

The processes that take place on or near the surface of the earth that makes the surface wear away. They cause degradation and wearing away of the Earth's surface.

The main types of exogenic processes are weathering, mass wasting, erosion, sedimentation.

Weathering is the breaking down of rocks to form soil. They can be physical, chemical or biological.

Erosion is the transportation of rock debris by geomorphic agents like running water, the wind, waves etc.

Deposition is the end result of erosion.

Sedimentation is the process of leaving sediment anywhere because of larger mass at the bottom level.
