The gravitational pull from the moon and sun causes

• moon phases

• eclipses

• tides

When the northern hemisphere is tilted away from the sun, it is

• Winter

• Summer

• Fall

• Spring

Which is most likely caused by the tilt of Earth on its axis as it revolves around the sun?

• lunar eclipse

• phases of the moon

• two high tides and two low tides each day

• opposite seasons in the Northern and Southern Hemispheres

When the bright part of the moon gets bigger (light move right to left),

• the moon is waxing.

• the moon is waning.

• the tides are changing.

• the moon is a new moon.

What occurs because of the revolution of Earth around the sun and the tilt of the Earth's axis?

• different seasons

• night and day

• lunar eclipses

• moon phases

Different angles of the moon's lit surface as the moon revolves around Earth cause

• cycles.

• moon phases.

• eclipses.

• tides.

Why are people on Earth unable to see the moon during the new moon phase?

• The lit side of the moon is not facing Earth.

• The sunlight is being reflected off the moon.

• The location of Earth is between the moon and the sun.

• The tilt of Earth is causing the moon to be blocked by the sun.

During the summer solstice,

• the Northern Hemisphere receives most sunlight; longest day of year.

• Northern Hemisphere receives less sunlight; shortest day of year.

• sunlight doesn't change.

• The Earth revolves around the moon.

• The Sun revolves around the Earth.

• The moon revolves around the Earth.
