Where must you be in order observe a total solar eclipse?

What is in the umbra.

100

The imaginary line that passes through the Earth's poles is called the ________________.

What is rotation axis.

100

What side of the Moon can we see from Earth?

What is the near side of the Moon.

200
What is a solstice?
What is a day when the Earth's rotation axis tilted the most toward or away from the Sun. (For us, the Winter Solstice is when the northern hemisphere is tilted away from the Sun, and the Summer Solstice is when the northern hemisphere is tilted towards the Sun).
200
When the Moon appears to be getting smaller it is called _____________.
What is waning.
200

When the Moon's shadow appears on Earth's surface it is a _____________ eclipse.

What is solar.

200

A large group is single stars, star systems, star clusters, dust and gas held together by gravity are called a(n) __________.

What is galaxy.

200
Why is Earth warmer at the equator and colder at the poles?
What is the equator receives more direct sunlight all year, whereas the tilt of the Earth on it's rotation axis impacts the amount of direct sunlight at the poles.
300
Explain the difference between rotation and revolution.
What is rotation is a spinning motion (example: the Earth spinning on it's rotation axis) whereas revolution is the motion of one object moving around another object (example: the Earth moving around the Sun).
300
The _____________ were formed when lava bubbled through the Moon's crust, forming large, dark, flat areas on the Moon's surface.
What is the maria.
300

During what Moon phase can a lunar eclipse occur?

What is a Full Moon.

300

Why is June 20th so scientifically special?

What is June 20th is the first day of summer, or the summer solstice for the northern hemisphere.

300
The attractive force between two objects is called ____________.
What is gravity.
400
What causes the seasons?
What is the tilt of the Earth on it's rotation axis combined with Earth's motion around the Sun.
400
Name the phases of the Moon in order, beginning with the New Moon.
What is New Moon, Waxing Crescent, First Quarter, Waxing Gibbous, Full Moon, Waning Gibbous, Third Quarter, Waning Crescent.
400

When the Sun is directly behind the Moon, what do we observe on Earth?

What is a solar eclipse.

400

What is the penumbra?

What is the lighter part of a shadow where the light is partially blocked - you would observe a partial solar or lunar eclipse in the penumbra.

400
What type of galaxy is the Milky Way?
What is a spiral galaxy.
500
What is a day when Earth's rotation axis is leaning along with Earth's orbit, neither toward or away from the Sun?
What is an equinox. There are about 12 hours of sunlight and 12 hours of darkness for everyone on Earth on this day.
500
If you traveled to the Moon, what about you would change, and what about you would stay the same? Why?
What is your weight would change because the gravitational pull on the Moon is about 1/6 what it is on the Earth, and your mass would stay the same.
500

What is the primary reason for Earth's tides?

What is the Moon's gravitational pull. The Sun's gravitational pull does have an impact on the Earth's tides, however because there is a greater distance between the the Earth and the Sun, it is not the primary reason for the Earth's tides.

500
