I gto 100% on this test so here are the aswers
4. 1 & 4
I can't swear by these answers, as I have not gotten my grade for this Introduction to planet earth test, but I think they are right. I would recommend that whatever answers you think are wrong, for goodness sakes', put the answer that YOU think is right. I'm not a troll and i'm just trying to be helpful and help people get good grades. The best answerer on this site is queen Elsa, but my answers are almost right all the time.

The moon’s surface is wet and smooth.
The moon’s surface is dry and irregular.
The moon’s surface has mountains and oceans.
The moon’s surface is exactly like Earth's surface.
10. Why can you never see the far side of the moon from Earth? (1 point)
because Earth is spinning too quickly
because it cannot be seen during daylight hours
because the moon rotates once on its axis in the same time that it takes to revolve around Earth
because the moon does not rotate
