Roughly. Anything that spins for incredibly long periods of time (I.E Billions of years) Natuarally becomes spherical, But if you want to be so incredibly accurate, No. Because of all the gaping holes and perilous mountains ect.
yes and no. the earth and moon are solid, but the moon if a star/ball of gas/ball of fire.
so again. yes and no. they are shaped like it. they are spheres but then again one is not a sphere from a certain point of view.
More or less. They are not exact spheres, but close enough for most practical purposes.
because they are all spheres!
No but they are of a spherical shape
The Sun, Earth and the Moon are all oblate spheroids. Meaning their equatorial diameter is greater than their polar diameter.
Centripetal Force.
Yes.
no it isn't the earth is a little flattened around the poles A circle is a two dimensional object. I think you mean are they spheres. In general, They are, but not perfect spheres. The equators bulge out slightly
The Earth is an inner planet, and all the inner planets are rocky. The Moon is made out of the same matter as the Earth, so yes, they are both rocky spheres.
Of Earth's four major spheres atmosphere, hydrosphere, and biosphere are absent or nearly absent on the Moon. This prevents many of the natural processes we see on Earth from happening on the Moon.

Spherical. They are approximately spheres. The earth is more of an oblate sphere, a squashed sphere - this is due to its spin.
The moon is revolving around Earth, so sometimes the Moon is between the Sun and Earth and Earth is between the moon and sun.
