The mass of the Earth is about 6 x 1024 kg and the mass of the moon is about 7 x 1022 kg.
The distance between the Earth and the Moon
is about 3.8 x 108
The magnitude of the gravitational force
between is closest to which of these?
m.

Well it seems that you did not give answer choices, but that its fine since we can use newtons law of universal gravitational, Fg = GM1M2/r^2. So G is the gravitational constant, which is 6.67*10^-11, we can plug in 6*1024 for M1, and 7*1022 for M2, and 3.8*108 for r. Which then we get 1.74 * 10^8 N as the force of attraction between the Earth and the moon.

mass and volume are the answers you are looking for

igneous rocks also form where plates converge. the subducting plate melts as it sinks into the crust of the earth, and the melt rises into the overriding plate forming volcanoes. metamorphic rocks are formed mainly in the lithosphere, wherever there is high pressure and high temperature. -woods
