• Sun

• Solar System

• Galaxy

• Universe

Multiple Choice

Object X is made of layers of solid and liquid rock and metals. Its outermost layer is a water ice shell. It is larger than the smallest planet, but does not orbit the Sun. Which type of object is it?

• a moon

• an asteroid

• an inner planet

• an outer planet

Multiple Choice

Hierarchical relationships are typically based on levels. The subordinate or lower-level objects are then all contained in the next category in the hierarchy. Which of the following correctly organizes astronomical bodies from largest to smallest?

• stars, solar systems, galaxies, planets

• universe, planets, solar systems, stars

• galaxy, planets, comets, stars

• universe, galaxy, solar system, stars

Multiple Choice

Here is a model of the gravitational force of Mars. Objects A and B have the same mass but are different distances from Mars. Which statement explains how the gravitational force affects the two objects?

• Object A and B will be affected equally by the gravitational force.

• Object B will be more affected by the gravitational force because it is closer to Mars than Object A.

• Object A will be more affected by the gravitational force because it is farther from Mars than Object B.

Multiple Choice

What would happen to your weight if Earth's mass was cut in half?

• increase because gravitational force increases

• decrease because gravitational force decreases

• decrease because gravitational force increases

• increase because gravitational force decreases

​Apparent vs Absolute

Multiple Choice

What is the main element in a stars composition? 

• Hydrogen 

• Helium 

• Lithium 

• Heavy Elements 

Multiple Choice

Scientists have determined that the star on the left is actually much brighter than the star on the right. What may best explain this difference between observation and reality?

• Iota Canis Majoris must be much smaller than Sirius

• Sirius is much closer to Earth than Iota Canis Majoris

• Iota Canis Majoris must have been dimmer in the past

• Sirius must create a lot more visible light compared to Iota Canis Majoris

Multiple Choice

Iota Canis Majoris has an apparent brightness of 4.36, while Sirius has an apparent brightness of -1.46. Even so, Sirius seems much brighter because it is much closer to Earth. If Sirius and Iota Canis Majoris were the same distance from Earth, which of the following statements would be true

• Iota Canis Majoris would appear to be smaller than Sirius

• Iota Canis Majoris would appear to be much brighter than Sirius

• Sirius would appear to be brighter than Iota Canis Majoris

• Sirius would appear to be hotter than Iota Canis Majoris

Multiple Choice

Based on the diagram, which star is brighter than our Sun but has a lower temperature?

• Sirius A

• Aldebaran

• Sirius B

• Alpha Centauri B

Multiple Choice

What is the difference between absolute brightness and apparent magnitude?

• Absolute brightness is the total amount of light emitted by the star and apparent magnitude is what color it appears

• Absolute magnitude is how brightly stars are shining, while apparent magnitude is how bright they look from Earth

• Absolute brightness is the core temperature and apparent magnitude is how bright it looks from Earth

• Absolute brightness is the star’s color and apparent magnitude is how bright it looks from Earth

Multiple Choice

• visible light

Multiple Choice

8. Within the visible spectrum of light, there are many colors: red, orange, yellow, green, blue, indigo, and violet. What characteristic of each of these colors makes this spectrum of light visible to the human eye?

• Each color has a different wavelength.

• Each color travels at a different speed.

Why do we experience the changing of the season on the earth?

• distance from the sun

• rotation of the earth

• change in solar output

• tilt of the earth's axis

Multiple Choice

Why is the Equator warmest?

• Because it is closest to the sun.

• Because it receives the most direct sunlight

• Because no clouds form here.

• Because it is far from the sun
