What's Earth's axis?
The imaginary point/line Earth rotates around.
3 multiple choice options
What is Earth's orbital plane?
A flat surface stretches past Earth's orbit and continues forever.
3 multiple choice options
What is one reason circumpolar stars are visible all year round?
They are located near the celestial poles, and due to Earth's rotation, they never dip below the horizon.
3 multiple choice options
Earth's rotation is a process that causes _________________.
all of the above
3 multiple choice options
Which of the following statements does NOT describe the behavior of a celestial object?
A communications satellite revolving around Earth.
3 multiple choice options
What object(s) does Earth revolve around?
The Sun.
3 multiple choice options
Which of these most closely describes the shape of an ellipse?
A thin oval.
3 multiple choice options
Our ability to observe the sun travel across the sky because we are standing on a moving object is an example of...
a cause and effect relationship.
3 multiple choice options
Earth rotates on its axis approximately once every _________.
day
3 multiple choice options
Why are seasonal stars only visible during certain times of the year?
Their visibility depends on Earth's position relative to the Sun.
3 multiple choice options
Why are circumpolar stars that reside below the South Pole not visible in Earth's northern hemisphere?
They are blocked by Earth.
3 multiple choice options
The overall pattern of the Sun rising toward the ast and setting toward the west _______________.
never changes
3 multiple choice options
The action of spinning on the axis is ____________.
rotation
3 multiple choice options
Why do stars seem to change their positions overtime?
Because Earth rotates on it's axis, making it seem as if they move.
3 multiple choice options
What are the two constellations on the Earth's orbital plane?
Orion and Scorpious.
3 multiple choice options
Circumpolar stars can be seen year-round.
True
1 multiple choice option
Why can Aussies not see Polaris?
Because it's blocked by the Earth.
3 multiple choice options
What is an axis of rotation?
An imaginary line passing through an object's center of mass around which the object rotates.
3 multiple choice options
Why do the Sun, Moon, and stars appear to rise in the east and set in the west?
Because of the way Earth rotates, it makes it seem in perspective that the celestial bodies are moving.
3 multiple choice options
Is a day the same length universally?
No: This is because of the difference in daylight hours each region gets.
1 multiple choice option
Why does the Earth spin?
Intertia.
3 multiple choice options
Why has the Earth's spin slowed?
It's slowed because the Moon's rotation, which moves the waves, tries to stop Earth's rotation.
3 multiple choice options
What will eventually happen to the Moon?
It will eventually drift away from Earth.
3 multiple choice options
What direction does Earth rotate?
Counterclockwise (west to east).
1 multiple choice option
Why is Earth farther from the Sun in the winter and closer in the summer?
Because Earth's orbit path isn't circular and elliptical path of Earth is sometimes closer to the Sun in the summer.
