Sun-Earth-Moon

During what phase of the moon can a lunar eclipse occur?

• new moon

• first quarter

• waxing gibbous

• full moon

For a solar eclipse to occur,

• the sun must be directly between the Earth and the moon.

• the moon must be directly between Earth and the sun

• the moon must be directly between the sun and moon

• Earth must be directly between the sun and the moon

During a total lunar eclipse the moon is in Earth's

• corona

• penumbra

• umbra

• orbit

In the Southern Hemisphere, the summer solstice occurs when the sun is

• at the equator

• farthest south

• farthest north

• closest to Earth

All objects are attracted to each other by the force of

• weight

• mass

• inertia

• gravity

The amount of the lighted side of the moon you can see is the same during

• new moon and full moon phase

• new moon and first quarter phase

• first quarter and third quarter phase

• full moon and third quarter phase

The phase of the moon you see depends on

• where you are on Earth's surface

• how much of the sunlit side of the moon faces Earth

• how much of the moon's surface is lit by the sun

• whether or not an eclipse is occurring

You are less likely to see a total solar eclipse than a total lunar eclipse because

• the moon's shadow covers all of Earth during a solar eclipse

• new moon phases occur less often than full moon phases

• only people on the daytime side of Earth can see a solar eclipse

• the moon's umbra only covers a small area on Earth's surface

Where might water be found on the moon?

• in the atmosphere

• inside moon rocks

• near the poles

• in the maria

The two factors that combine to keep Earth and the moon in their orbits are

• gravity and orbital speed

• orbital speed and mass

• mass and inertia

• gravity and inertia
