The Earth is also revolving around the Sun, so the Moon must catch up

Why is there a difference between the sidereal and lunar

months?

$1000The phase will be full because it is rising opposite the sun. If the moon is directly opposite of the sun in the sky it will be a

full moon

If the moon rises at sunset, what phase will it be in? Why?

$200

23.5 degrees

What is the tilt of the earth on its axis?

$400

year

The time it takes for Earth to complete an orbit around the Sun is called.

$600

equinoxes

The places where the Sun crosses the equator are called

the

$800

is Polaris in the sky

47 degrees

$200

Northstar

Of all the visible objects in the sky, which appears to

move the least?

$400

Shorter distance

Is a star with a large parallax and great distance or short

distance from earth

$600

Precession

The fact that Polaris will not always be the North Star is due to what Earth motion?

$800

26,000 years

How long is the precession cycle

$1000He realized that the sun was directly overhead in one city and at a slight angle in another at

the same time and therefore realized the Earth was curved. He realized the distance between the cities was a 7 degree difference or about
