What happens to the comet when the comet approaches the sun?
Its body begins to melt, releasing its frozen gases into space. The gases spread out to form a huge misty head around the comet's front end.
300
The big and little dipper can be found where?
In the same area ALWAYS in the northern sky

How many times does the Earth rotate on its axis, and how long does it take?
1 rotation: 24 hours
300
What star can be seen at certain times on the eastern horizon?
Morning Star

Use what you have learned about the apparent motion of the stars to explain how stars might be used as a navigational tool.
Because Polaris lies directly above the North Pole, it appears almost motionless. Navigators can locate Polaris to determine which direction is north.

What is the dirt particles left behind by the comet which then speed up into Earth's atmosphere and burn up there as "shooting stars?"
Meteors
400
What do astronomers use constellations for?
identify the address of a certain sky object

Turn to page B13 and look at the photo of the Earth in the sky, and explain why the star tracks in the photo are circles instead of straight lines.
The tracks are circles because of Earth's rotation, which is a circular movement around a fixed axis.

What 3 traits do the planets share with the morning star?
They shine steadily, appear in the telescope as disks, and move against the backdrop of the other stars.

Frozen water, ammonia, and methane

compare the movement of the Earth around the Sun to the movement of a baseball thrown to home base. Use scientific terminology
A curveball spinning and moving toward home plate has the same rotation as the Earth rotating and revolving around the Sun. The ball is not just spinning, but moving from the mound to home plate. The fly is able to to view the girl from now the front of the ball because of the rotation of the ball moving to the plate (much like the earth's rotation and season changes as it revolves around the Sun)
500
What motion of the Earth causes the Sun to seem to rise and set each day?
The rotation of Earth causes the Sun to seem to rise and set each day
500
Sir Isaac Newton designed what type of telescope for what reason?
Reflecting telescope that would collect light in a mirror before passing it through a lens.

How does studying meteorites help scientist learn about comets?
Meteorites can sometimes come from comets. Therefore, studying meteorites can help scientist learn the composition of comets.
