Asked by Bryce

My teacher didn't have time to finish the lesson day, and I can't find the answers anywhere online or in my book.

What are 2 main ways in which the earth moves? What does each movement cause?

I have it rotates on its axis which causes seasons, but I cant think of other ones.

What is the difference bewtween a sidereal day and a sidereal month?

Where is the sun when days and night are equal in length?

I have NO clue

How does the crescent phase that precedes the new moon differ from the crescent phase that follows the new moon?

On which date would I be receiving the longest amount of sunlight?

In addition to rotating on its own axis, doesn't the earth also rotate around our sun?

Keep searching ... the answers are there somewhere. Sometimes you have to change the search terms.

Use http://www.answers.com and http://www.google.com and http://www.bing.com (among others)

what date receives the longest amount of sunlight? Im not sure of the date
Answered by Ms. Sue
Are you asking about the Northern or Southern Hemisphere?

Check for summer solstice.

Answered by Bryce
Is the crescent moon phase question this:

The moon phase that precedes is to the right side of the moon, while the moon phase after is to the left.
Answered by Bryce
wait, its the other way around!

and im guessing the equinox is when the days night ares are equal in length? but its asking where the sun is? This is so confusing

Just FYI, earth's rotation on its axis causes day/night, not the seasons.

The earth's axis tilts from being perpendicular to the plane of the ecliptic, and that is what causes the seasons. (The orbit of earth is very very close to circular, so earth's revolution about the sun has little affect on the seasons.)
Answered by Steve
dang - that's "effect"!
I hate it when people misuse affect and effect. :-(
