The ________ and __________ of an object in the sky tells us where it is in the sky. What are these values for the North Star, if this star is almost directly North and is approximately 1/3 of the way "up the sky"?
Azimuth and altitude.
Approximately azimuth = 0, altitude = 30 degrees.

Name the two different types/categories of telescopes, and name the primary difference between them.
Refracting/reflecting telescops. One uses a lens to focus light, one uses a curved mirror.

This word means an apparent shift in an object when viewing it from two different places.
Now, draw a diagram describing how this is used to determine the distance to a nearby star.
Parallax.

Write the following as a single power:
(x^10\times(x^20)^2)/(x^2\timesx^3)
(x^10\times(x^20)^2)/(x^2\timesx^3)=x^50/x^5=x^45

Mercury has no atmosphere. Name two things that are true about Mercury as a result of not having an atmosphere.
It's hot, but not as hot as Venus because it has nothing to "trap heat". It's also covered in craters because it has nothing to protect it from asteroids.
