Planet A
Planet B
Planet C
Four planets, called A, B, C, and D, have orbital periods as shown in the table below. Which planet is farthest to the sun?
Planet A
Planet B
Planet C
Which shape is used to describe the orbit of a planet around the Sun?
circle
ellipse
parabola
Which surface is likely to be older?

A
B
They are the same age
What does the presence of water on Earth likely indicate about its early history?
Earth was once completely covered in ice
Earth's core was initially liquid
Water was brought by comets and asteroids
A collision with another small planet likely explains the formation of:
Earth's core
The moon
The first continents
What does 1 astronomical unit (AU) represent?
The distance across our solar system
The distance between the Earth and the Sun
The time it takes light to travel from the Sun to Earth
Scientists think water may exist elsewhere in our Solar System besides Earth.
True
False
Which crater in the image is younger?

A
B
They are the same age
Which planet would you expect to have the longest year (time it takes to go around the Sun once)?
Uranus
Mercury
Venus
Which planet would you expect to have the shortest year (time it takes to go around the Sun once)?
Mercury
Uranus
Venus
What have scientists used to determine how the Moon was formed?
Rock samples from the Apollo missions
Samples taken from nearby asteroids
Magma from the Earth's mantle
Match the meteroid to its description.
Meteorite
can be described as a "dirty snow ball"
Comet
small rocky remnants from the formation of the solar system
Asteroid
"shooting star" that burns up in Earth's atmosphere
Meteor
Pieces of space rocks that reach the Earth's surface
Which crater is likely to be the oldest?
Categorize each description as a characteristic of "terrestial planets" or "ice giants."
Rocky, solid surface
Gasous, non-solid surface
Closer to the Sun
Farther from the Sun
Small
Large
Terrestial planets
Ice giants
What separates the terrestial planets from the ice giants?
Asteroid belt
Kuiper belt
Oort cloud
Why do scientists study lunar rocks and meteorites to understand Earth's formation?
They are easier to find than Earth rocks
They are more accurate than radioactive dating
They provide evidence of conditions in the early solar system
Planets orbit the Sun in perfect circles.
True
False
What is the purpose of scientific models?
To make science more confusing and difficult to understand.
To represent and explain complex systems and phenomena in a simplified way.
To provide exact predictions without any errors.
How do models connect what happens on a small scale (like molecules, cells, or parts of a machine) to what happens on a larger scale (like ecosystems, human health, or whole devices)?
By representing small-scale processes to explain and predict large-scale behaviors
By ignoring small-scale details and only describing large-scale patterns
By using random guesses to link small-scale and large-scale phenomena
Categorize the statements about scientific models into two categories by dragging the statement to each correct category. (Statements can only be used once and all are used)
predict outcomes
be uncertain
guide experiments
represent complex phenomena in understandable ways
be incomplete
oversimplify reality
Limitation (Weakness)
Advantage (Strength)
