Hey, do you think you can help me with these questions? I'll give some extra points(can give more if needed)
rjkz [21]

Answer:

1. Both neutron stars and black holes are the corpses of stars that died in explosions known as supernovas. Black holes form when the most massive stars die and neutron stars form when stars not as large die. They both have a very strong gravitational pull, but a black hole's pull is stronger than a neutron star. Neutron stars <u>will turn into</u> black holes if the force of gravity breaks the resistance of electrons.

2. White dwarfs are degenerate, which means they can compress matter. The material in a white dwarf no longer undergoes fusion reactions, so it is supported only by electron degeneracy pressure. This causes it to be extremely dense, saving space and energy.

3. A light year is the distance light travels in a year while an astronomical unit is the average distance between the earth and the sun.

4. A convection zone transfers energy by radiation and conduction.
