Question

1. why are solar prominences unable to leave the suns atmosphere? gravity draws them back in. they occur for only a few seconds. their arches are very insignificant. the electric charges easily reach humans on earth.

Explanation:

Solar prominences are large, bright features extending outward from the Sun's surface. Gravity is a fundamental force that acts to pull matter towards the center of a massive object. The Sun has a strong gravitational pull due to its large mass. Prominences are made of plasma (hot, ionized gas). The gravitational force of the Sun is strong enough to prevent the plasma in prominences from escaping the Sun's atmosphere.
The second option is incorrect because prominences can last for hours to days, not just a few seconds. The third option about arches being insignificant is not relevant to why they can't leave the atmosphere. The fourth option about electric charges reaching humans on Earth is also not related to the inability of prominences to leave the Sun's atmosphere.

Answer:

Gravity draws them back in.
