ITS AXIS
100
The Earth's path around the sun is called this
ORBIT
100
The direction you must be looking towards to see the sunrise.
EAST
The Sun rises in the east.
100
TRUE or FALSE?
The Earth's revolution around the sun causes day and night.
FALSE
100
What is the outermost region of the sun's atmosphere called?
Corona
200
The earth takes this long to complete one rotation.
24 HOURS or ONE DAY
200
The earth revolves around this.
THE SUN
200
This is the direction of the sunset.
THE WEST
200
This is happening when the sun is shining on certain part of the Earth?
Daytime! 
200
What particularly violent solar event, also known as a coronal mass ejection (CME), causes beautiful auroras (Northern/Southern Lights) on Earth?
Solar Flares
300
This is caused by the Earth's rotation.
What is DAY and NIGHT?
300
The earth takes this long to complete one revolution.
365 1/4 days or ONE YEAR?
300
TRUE OR FALSE
The Earth is always half lit.
What is TRUE?
300
This is happening when a part of the Earth is rotated out of the sun's light?
Nigh time!
300
How does the temperature of the sun's core compare to the temperature of the corona?
Much Hotter at the core
400
Do all planets rotate in the same direction?
No. Venus and Uranus rotate towards the West or clockwise.
400
Why do planets in our solar system revolve around the Sun?
Because it is the most massive object in our solar system.
400
The sun rises in the east and sets in the west because the earth spins in this direction.
Towards the East or counterclockwise
400
What would happen if the Earth stopped rotating?
No day and night
400
Describe thermonuclear fusion including the reactants and products?
Two hydrogen atoms fuse to produce Helium and a release of energy
500
This is something special about the earth's axis.
IT IS TILTED
500
Why will our solar system's planets not collide if they stay in their orbit?
Because all planets in our solar system share a similar orbital plane, planets don't run in to each other.
An orbital plane is the flat, disk-shaped space that connects the center of the object being orbited with the center of the orbiting objects.
500
When the Sun appears to move across the sky, this is what is really happening.
The Earth is rotating in and out of the sun's light.
500
About how fast is the Earth rotating in and out of the sunlight?
About 1000 miles per hour
500
What is the stream of electromagnetic energy from the corona called?
Solar Wind
