Why does the earth rotate?
a. because earth is formed from cold gases collapsing due to gravity
b. because the matter in the nebula that formed earth was spinning
c. because earth forms more than 99% of the mass of the solar system
d. because the hydrogen atoms inside the nebula fused to form helium

the answer I think is A im so sorry if its wrong

Explanation:

Because yes we do have gases collapsing we also have dust collapsing with it and surrounding it to make a disk type of air flow that pushes it that makes it rotate if that makes sense. yet again super sorry if its wrong.

the answer is actually B

Explanation:

When our solar system formed out of a gas cloud, called a nebula, there was lots of dust and gas coming together due to the force of gravity. The dust and gas was already moving around in a circle. As it all clumped together to form the Sun and planets, these new objects started to spin – and then spin faster.

i hope this helps!!!

i believe the answer would be:

d. violin, clarinet, french horn, and tuba

here are some information of the future of geothermal energy:

-the future of geothermal energy can pretty much be summed up with a single word: more

-scientists plan in going deeper than 120 meters

-we are hoping that one day, we will get all of our energy from renewable energy sources such as geothermal energy

hope this !
