How does the sun create energy?

Back to Menu

The sun uses nuclear fusion, combining two hydrogen

atoms into one helium atom.

True or False: the sun has 4 types atmospheres.

Name them!

False. There are 3 atmospheres: Photosphere,

Chromosphere, and Corona.

Back to Menu

What are Sunspots?

Sunspots are areas of gas that are cooler than the gas around them,

making them appear as dark spots.Back to Menu

How are Solar Flares and Prominences related? What is

different about them?

Prominences are loops of gas that connect sunspots. Solar

Flares are when loops connect suddenly or explosively.

Back to Menu

What does the picture below represent? What

causes it?

This is Aurora Borealis. The Solar Wind (a stream of electrically charged particles) hit Earth’s Magnetic field and are drawn to the poles.

If you weigh 240 pounds on Earth, you would feel like you were only 40 pounds on the moon. Therefore, the

gravity on the moon is…a) 1/2 that of Earthb) 2 times that of Earthc) 1/6 that of Earthd) 6 times that of Earth

What unusual relationship does the moon’s rotation and

revolution share?

Back to Menu

They are both equal (27.3) days, making one day on the moon

equal to one year on the moon.

How do scientists think the moon was formed?

Back to Menu

Scientists think a massive object crashed into Earth and threw pieces into space.

Earth’s gravity caused the pieces to orbit and slowly accrete (come together).

Name the phases of the moon highlighted below.

The phases are…

Describe Rotation and Revolution.

Rotation is the spinning of an object about an axis.

Revolution for is the movement of orbit of one object around another.

Back to Menu

What is an axis, and what is the angle of Earth’s axis?

An axis is an imaginary line that passes through the center and

North & South poles. Earth’s axis is titled at 23.5 degrees.Back to

Menu

What does the tilted axis cause? What is a common mistake people

believed about this instead?

Back to Menu

The tilt of our axis causes the seasons. Many people think our

distance to the Sun causes seasons.

If it is the Winter Solstice in the N. hemisphere, what does that mean for the S. hemisphere?

Final Jeopardy

Back to Menu

The Winter Solstice is the day when there is the least amount of daylight.

In the S. hemisphere they would be experiencing the most amount of daylight.

Name the two types of eclipses.

Lunar Eclipse and Solar Eclipse.

Back to Menu

What position must the celestial bodies be in to cause a Lunar Eclipse?

Back to Menu

The order must beSun Earth Moon.

What position must the celestial bodies be in to cause a Solar

Eclipse? What part of the Sun is visible during this time?

Back to Menu

The order must beSun Moon Earth. The corona is visible during this time.

What phase(s) must the moon be in if a Solar Eclipse is to occur?

Back to Menu

A Solar Eclipse can only occur when the moon is in its New phase.

The shadows cast by either the Earth or moon during either type of eclipse

have to parts. Describe them.

Final Jeopardy

Back to Menu

The two parts of the shadows are called the Umbra and Penumbra.

The Umbra is the darkest part, while the Penumbra is the larger, less dark part.

Consider this: •The Sun is roughly 150 million kilometers from Earth.

•Light travels at 300 million meters per second, and 1km is equal to 1,000 meters.

•If the Sun stopped shining, how long afterwards would it take before we ran out of light?
