Use this image to determine letter B.

The apparent wavelength shifting of electromagnetic energy (such as visible light) caused by the relative motion between the energy source and the observer

Idea that Earth was at the center of the solar system

The motion of one body around another in an orbit

A faint glow of light "echo" that fills the universe, falling on Earth from every direction with nearly uniform intensity

American astronomer who determined that the universe is expanding based on red shift of objects in space. (Raisin Bread)

Credited with the creation of the geocentric model of the universe.

In 1824, he explains sound phenomenon by showing shifts of frequency or wavelength. This idea helps to explain the Redshift.

Credited with saying the sun was the center of the universe

Used the telescope to help show that the Earth was not the center of the Universe by observing Jupiter and its moons.

Which statement best describes the geocentric model of our solar system?

Some constellations can only be seen during certain seasons because

Which results from Earth’s rotation?

Earth has seasons because

How much of the moon is always reflecting light from the sun?

Which pattern of changes takes about a month to complete?

A recent theory attributes the origin of the moon to the impact of a Mars-size body with the Earth. Which of the following is both a true statement and supports the impact theory of the moon’s origin?

Earth’s axis is tilted with respect to earth’s orbit at an angle of

A Foucault pendulum provides evidence of Earth’s

Which two observers would be experiencing the same apparent time?

A similar principle explains both redshift and the Doppler effect using waves and wavelengths.

Red light has a shorter wavelength than blue light.

Sound waves that are close together illustrate high pitch.

The universe is getting smaller.

The gamma ray has the longest wavelength on the electromagnetic spectrum.

Which diagram best represents a heliocentric model of a portion of the solar system? (diagrams are not drawn to scale) Key E= Earth; P= Planet; S= Sun)

Which model of the solar system do we follow today?

How many days are required for the Moon to complete a cycle of phases from the new Moon position to the new Moon the following month?

How many days are required for the Moon to rotate and revolve?

What Moon phase is represented by letter AD?

Because the Earth turns ______ in 24 hours it turns ______ every hour.

If 15° = 1 hour difference then 1° = _____ minute difference.

East: _____

Equator: _____

In the northern hemisphere, which is the actual path an object will travel?

Which diagram below represents the phase of the Moon, as seen by an observer on Earth, when the Moon is located at position A in its orbit?

Approximately how many days occur between the Moon's first-quarter phase and the Moon's last quarter?

The same side of the Moon always faces Earth because

A cycle of Moon phases can be seen from Earth because

The diagram below shows the Moon at one position in its orbit around Earth. Letter X indicates the location of an observer in New York State. Which phase of the Moon will the observer see when the Moon is at the position shown in its orbit?
