Temperatures would remain mostly constant year-round.

All of the above

you see some phases more than others.

a different side of the moon faces Earth each day.

you never see the far side of the moon from Earth.

the far side of the moon is visible only during the full moon phase.

during the moon’s first quarter phase

when the sun, Earth, and the moon are nearly in a line

during the moon’s third quarter phase

when the moon is at a right angle to the sun

at new moon

when the sun’s pull is in the same direction as the moon’s pull

when the sun’s pull is at right angles to the moon’s pull

at full moon

When the moon is in the first quarter

When the sun’s rays are most intense

When the sun, moon, and Earth are all lined up

When the sun and moon form a right angle with Earth

The side of Earth facing the moon and the opposite side have the highest tides.

The highest tides always occur when the moon is in its first quarter and third quarter phases.

The side that is furthest away from the moon experiences the least gravitational pull and has the lowest tides.

The tides correspond to the angles of Earth and the moon so the highest tides are when they are at 90°.
