Revolution is the movement of the Earth around the Sun.

What two factors are responsible for the creation of the seasons?
The tilt of the Earth's axis and the revolution of the Earth around the Sun.

How could you use the phases of the moon to keep track of the date?
It takes 28 days for the moon to go through all of its phases. By keeping track of what phase the moon is in you can keep track of how much time has past.

Does the moon make its own light? Explain your answer.
No, the moon does not make its own light. Sunlight is reflected off of the surface of the moon to illuminate it.
200
Which way does the Earth rotate.
Counter-clockwise

In science terms, what is a year?
A year is the time that it takes to revolve around the Sun once.

Look at picture #1. What is the seasons in the Northern Hemisphere at Point D.
Spring.

What is responsible for the phases of the moon?
The positions of the Earth, Moon, and Sun.

What force keeps the Earth in orbit around the Sun and the Moon in orbit around the Earth
Gravity

Draw the Earth rotating.
300
Draw a picture of the Earth revolving.

What season is it in the Northern Hemisphere when it is spring in the Southern Hemisphere?
Fall

Why do we always see the same side of the moon.
The moon takes 28 days to rotate on its axis and 28 days to revolve around the Earth. As a result, we only see one side of the moon.

Explain how a lunar eclipse is created.
The Earth moves between the Sun and the Moon. The shadow of the Earth puts the Moon into darkness.
400
In science terms, what is a day?
A day is the time it takes the Earth to rotate once around its axis.
400
What shape is the Earth's orbit.
Ellipse
400
During which season is there the longest days? Why are days longest then?
Day length is the longest during the summer. Days are longest then because the Earth is tilted towards the Sun.
400
Draw and label the phases of the moon from new moon to full moon and back to new moon.
400
Draw a diagram of a solar eclipse.
500
How are day and night created?
When the Earth rotates around it axis, the half of the Earth that is facing the Sun is in day and the half that not facing the Sun is in night.

Compare the Earth and Moon's revolutions. Include information about what they are revolving around and how long the revolution takes.
Earth: revolves around the Sun and it takes 365 days.
Moon: revolves around the Moon and it takes 28 days.
500
If the Earth's axis was straight up and down, how would the seasons be different?
Seasons would not really exist. All areas of the Earth would have similar climates.
500
Look at picture #2. What phase of the moon is it at letter T?
New moon.

Imagine the Earth rotates north to south (instead of east-west).
a) How would night and day be the same as they are currently?
b) How would night and day be different than they are currently?
a) similar hours of day and night
b) the sun would rise and set in the north and south
