Barnard’s Star
Procyon B
Betelgeuse
Sun
7
Eclipses do
not
occur every month because the Moon’s
period of revolution is 27.3 days
orbitis inclined to Earth’s orbit
period of rotation and period of revolution are the same
rate of rotation is 15° each hour
8

radioactive decay
gravitational pull
heat transfer
nuclear fusion
9
Which motion causes regular seasonal changes of the constellations visible in the night sky?
Earth orbits the Sun
The Moon orbits Earth
The stars orbit Earth
The stars orbit the Sun
10

rotation on its axis in a geocentric solarsystem
revolution around the Sun in a heliocentricsolar system
rotation on its axis in a heliocentric solarsystem
revolution around the Sun in a geocentric solarsystem
12
In the Northern Hemisphere, planetary winds deflect to the
right, due to the Doppler effect
left, due to the Doppler effect
right, due to the Coriolis effect
left, due to the Coriolis effect
13
Compared to the terrestrial planets, the Jovian planets have
greater average densities
longer periods of revolution
smaller diameters
slower rates of rotation
14
Why do the planets in our solar system have a layered internal structure?
The Sun exerts a gravitational force on the planets
All planets cooled rapidly after they formed
Cosmic dust settled in layers on the planets’ surfaces.
Each planet is composed of materials of different densities.

25
Why is the same side of the Moon viewed from Earth as the Moon goes through its phases?
Moon’s period of rotation equals Moon’s period of revolution
Moon’s period of rotation equals Earth’s period of rotation.
Moon period of rotation equals Earth’s period of revolution
The Moon does notrotate as it revolves around Earth
