Our timekeeping system is based on the

• sidereal day

• solar day

• phases of the moon

• Earth's tilt

Scientists hypothesize that the Moon's crust is twice as thick

• in the highlands

• in the mana

• on the side seen from Earth

• on the far side

The layers of the Moon, from the surface inward, are the

• upper mantle, lower mantle, crust, and core

• crust, core, upper mantle, and lower mantle

• crust, upper mantle, lower mantle, and core

• upper mantle, crust, core, and lower mantle

The most commonly accepted theory about the origin of the Moon explains why the Moon and Earth have similar compositions.

• the Moon is so far away from Earth.

• the same side of the Moon is always seen from Earth.

• the Moon has very little regolith.

• the Moon and Earth have similar compositions.
