Answer:
D. it will expand and become a red giant.
Explanation:
In the main phase of any star's life, hydrogen is being fused into helium inside the core. This phase takes up 90% of the star's life span, and this is the phase the sun is at now. The next phase is where it turns into a red giant. Once the hydrogen has completely turned into helium, the inert helium ash collapses on itself. Which in turn causes the core to get denser and heat up, which also expands its size. It appears red because outer surface is a lower temperature, that makes it appear red (hence the name "Red Giant")
Answer:
Difference is given as under
Explanation:
- Mountain belts or mountain ranges are a line of hills connected by high ground. Usually an orogeny most of them are a result of plate tectonic effects and maybe young may be old depending upon their characteristic composition. Like the Himalayas is a young fold mountain formed in the tertiary system of rocks.
- Usually, the mountain is separated from highlands, valleys, and passes. Usually, they tend to regulate the climate affecting snow and rainfall patterns. As compared to the stable interiors upon concerning their age are mostly young as they are continuously on the move and their formation is impacted by erosion and continuous wear and tear of geomaterials.
- Concerning the height, the continents are lower as compared to the high elevated landmasses. Though the continents have large landmass and landscape is composed of various elements as mountain belts are smaller as composed to chains connecting the continents at the edges and borders.
- Only continental mountain belts like the arctic and antarctic circle have a large scale of mountain chains and ranges on earth that are since millions and billions of years ago the formation of super landmasses.
