Stars with higher mass have shorter lifespans. When the sun becomes a red giant, its atmosphere will engulf the Earth. During the red giant phase, a main sequence star's core collapses and burns helium into carbon. After about 100 million years, the helium runs out, and the star turns into a red supergiant.
I hope this finds you what you were looking for.
I believe the left chamber has a higher concentration of neon gas because it has more neon atoms in it, and the right chamber has a higher concentration of helium gas because it has more helium atoms in it.
It is a process<span> called termination.</span>
Answer:
D. Thermal expansion
Explanation:
MECHANICAL WEATHERING
can be defined as the gradual disintegration of rock into smaller particles which later turn into soil. when mechanical weathering occurs, it doesn't change the chemical composition of the rock. mechanical weathering are caused by abrasion by ice water, thermal expansion, root of trees growing on the rock.
THERMAL EXPANSION
This is a mechanical process of weathering. during the day when there is high temperature and hits the rock surface, the rock absorbs heat expands . at night when the temperature drops the rock contrast. Repeated action of expansion and contraction results in gradual breakdown of rock to form soil.
