The two objects that are often similar in size are moons and meteors. Moons can vary in size but are typically much larger than meteors, which are small rocky or metallic bodies that enter a planet's atmosphere. However, some moons are relatively small, similar in scale to larger meteors.
A student creates a diagram comparing the sizes of objects in the
solar system.

A student makes a chart about galaxies and mentions that the universe consists of many galaxies such as the Andromeda galaxy and the Milky Way galaxy.
Which statement is true about these two galaxies?
(1 point)
• They both exert a strong gravitational pull on each other.
• They are both moving away from each other.
• The Milky Way is a spiral galaxy, and the Andromeda galaxy is not.
• The Milky Way galaxy is larger than the Andromeda galaxy.

• They both exert a strong gravitational pull on each other.
• They are both moving away from each other.
• The Milky Way is a spiral galaxy, and the Andromeda galaxy is not.
• The Milky Way galaxy is larger than the Andromeda galaxy.
The correct statement about the Andromeda galaxy and the Milky Way galaxy is: They both exert a strong gravitational pull on each other.
The Milky Way and Andromeda galaxies are contending with each other gravitationally, and they are on a collision course that is expected to result in their eventual merger in about 4.5 billion years.
Which statement best describes the distances between planets in the solar system? (1 point)
• It increases the farther you move from the sun.
• It decreases the farther you move from the sun.
• It stays the same for all planets in the solar system.
• It has varying distances with no specific pattern.
• It increases the farther you move from the sun.
• It decreases the farther you move from the sun.
• It stays the same for all planets in the solar system.
• It has varying distances with no specific pattern.
The statement that best describes the distances between planets in the solar system is: It has varying distances with no specific pattern.
The distances between the planets are not uniform and can vary significantly as you move from the Sun to the outer planets. Each planet's orbit is influenced by various factors, leading to a complex arrangement of distances.
Why do students and scientists construct scale models of natural phenomena? (1 point)
• to collect data from natural events
• to correct mistakes in nature
• to define new units of measurement
• to better observe patterns and relationships
• to collect data from natural events
• to correct mistakes in nature
• to define new units of measurement
• to better observe patterns and relationships
Students and scientists construct scale models of natural phenomena to better observe patterns and relationships. Scale models help simplify complex systems, making it easier to study and understand the behavior and interactions of different components.
Which planet is approximately four times larger than the diameter of Venus on a scale model? (1 point)
Earth
Mars
• Mercury
• Neptune

Mars
• Mercury
• Neptune
The planet that is approximately four times larger than the diameter of Venus on a scale model is Neptune.
In terms of size, Neptune has a diameter of about 49,244 kilometers, while Venus has a diameter of about 12,104 kilometers. Therefore, Neptune is roughly four times larger than Venus.
How does distance affect gravity? (1 point)
• Gravity increases with increasing distance.
• Gravity increases with decreasing distance.
• Gravity is zero at any point in the solar system.
• Gravity remains the same regardless of distance.
• Gravity increases with increasing distance.
• Gravity increases with decreasing distance.
• Gravity is zero at any point in the solar system.
• Gravity remains the same regardless of distance.
The correct statement is: Gravity increases with decreasing distance.
Gravity is a force that pulls objects toward each other, and its strength decreases as the distance between two objects increases. Thus, the closer two objects are to each other, the stronger the gravitational pull between them.
