question 4
as the sun ages, what will happen to life here on earth? why?

Explanation:

As the Sun ages, it will exhaust hydrogen fuel in its core, expand into a red giant, and increase in luminosity. This will raise Earth’s temperature, boil away oceans, and strip its atmosphere, making life impossible. Later, the Sun will shed its outer layers and become a white dwarf, leaving Earth a barren, cold planet.

Answer:

Life on Earth will eventually cease to exist. The aging Sun will expand into a red giant, heating Earth to uninhabitable levels, and later become a white dwarf, leaving Earth cold and barren.
