Stellar evolution is the process by which a star undergoes a sequence of radical changes during its lifetime. Depending on the mass of the star, this lifetime ranges from only a few million years (for the most massive) to trillions of years (for the less massive), considerably more than the age of the universe. ^ 

Small, relatively cold, low mass red dwarfs burn hydrogen slowly and will burn for hundreds of billions of years 

Massive hot supergiants will live for just a few million years. 

A mid-sized star like the Sun will remain on the main sequence for about 10 billion years. Hope tis helps!!

When humans dig-up fossil fuels and burn them to power the modern world, carbon flows between which two reservoirs of the carbon
Luda [366]

Answer:

B

Explanation:

When humans dig-up fossil fuels and burn them to power the modern world, <u>carbon flows between the Geosphere/lithosphere and the atmosphere.</u>

Both the geosphere and the atmosphere represent important reservoirs of carbon. The digging-up of fossil fuels, otherwise known as exploration, is carried out in the geosphere or the lithosphere part of the earth. For example, crude oil is obtained deep from the ground. When the fuels are burned, they release carbon in the form of carbon dioxide into the atmosphere.

<em>Hence, it can be concluded that carbon flows from the geosphere/lithosphere part of the earth to the atmospheric portion of the earth when fossil fuels are burned.</em>

The correct option is B.
