Answer: is expanding

Explanation:

A supernova is a stellar explosion that occurs as a result of the final stage of a star's life. This event can be very remarkable, even observable to the naked eye. This means that supernovae are characterized by very intense flashes of light that can last from several weeks to several months. In addition, its luminous intensity increases rapidly until it reaches an absolute magnitude greater than the rest of the galaxy, and then gradually loses its brightness until it disappears completely.

Then, a supernova is a very bright element, however, as its distance from the observer is greater, they will be less luminous (look fainter). This is presented as proof that we live in <u>a universe that is expanding</u> and is not flat.

  • 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.
