Question

the amounts of both hydrogen and helium will decrease over time.
the amount of helium will increase, and the amount of hydrogen will decrease over time.
the amount of hydrogen will increase, and the amount of helium will decrease over time.
the amounts of both hydrogen and helium will increase over time.
how does energy produced in the suns core eventually reach earth?
energy is transferred through space by radiation in the form of electromagnetic waves
energy moves through space by conduction between air particles
energy is carried through space by convection currents.
energy travels by sound waves through space.

Explanation:

For the first question: The Sun generates energy via nuclear fusion in its core, where hydrogen nuclei fuse to form helium. This process consumes hydrogen and produces helium, so hydrogen decreases while helium increases over time.

For the second question: Space is a near-vacuum, so conduction (requires particles) and convection (requires a fluid medium) cannot transfer energy through it. Sound waves also need a medium to travel. Solar energy reaches Earth via electromagnetic radiation, which can propagate through empty space.

Answer:

1. The amount of helium will increase, and the amount of hydrogen will decrease over time.
2. Energy is transferred through space by radiation in the form of electromagnetic waves
