Question

Help me please.

Why does 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

Answer 1

I think it's B but I'm not 100% sure srry if I'm wrong

Answer 2

explanation :-

As Earth rotates, the Moon's gravity causes the oceans to seem to rise and fall. (The Sun also does this, but not as much.) There is a little bit of friction between the tides and the turning Earth, causing the rotation to slow down just a little.

answer will be B) Because the matter in the nebula that formed Earth was spinning
