100
What is the sun made of?
Hot gases called plasma.
100
What is the moon made of?
It is like a giant rock in space. It has almost no atmosphere.
100
What causes day and night on Earth?
The earth's rotation. When we are facing the sun, it is daytime, and when we are facing away, it is night time.
100
What causes the Earth's seasons?
The earth revolves around the sun, and the angle of the sun changes depending on where Earth is in its orbit.
100
What does rotate mean?
To spin around an object (the Earth spinning around its axis.)
200
Describe the relationship between the movements of the sun and the earth.
The Earth revolves around the sun, and the sun is the center of our solar system.
200
Why can we only see one side of the moon from Earth?
The Moon's revolution and rotation take the same amount of time.
200
When does the Earth receive the most direct sunlight?
Noon.
200
Describe the position of the Earth in June.
The North end of the Earth's axis is tilted towards the Sun.
200
What is an orbit?
An orbit is a path that an object (or planet) takes around the sun.
300
List 3 important characteristics of the Sun.
The core is 15 million degrees C, sun provides energy to the Earth, the sun has no solid surface, outside the core are swirling layers of plasma
300
Explain why the Moon appears bright at night.
The moon does not have light of its own. The light from the sun reflects off of the Moon's surface.
300
Why does the Sun always seem to rise in the East?
Because the Earth spins from west to east.
300
When the South Pole tilts away from the Sun, what is the weather like in the Northern hemisphere?
It is very warm. It is either Summer or Spring.
300
Describe the difference between an orbit and a revolution.
An orbit is the particular path that an object takes, while revolve means to move around an object.
400
What is a solar eclipse?
A solar eclipse happens when the Moon blocks the light of the Sun. The Moon is directly between the Sun and the Earth.
400
What is a lunar eclipse?
A lunar eclipse is when the Moon passes through the Earth's shadow. The Earth is directly between the Sun and the Moon.
400
Why does the sunrise/sunset time change throughout the year?
Because the Earth receives different amount of sunlight depending on where it is in its orbit.
400
Why are the temperatures always warmer near the equator?
Because the Earth is tilted on its axis, the equator always receives more direct sunlight than other parts of the Earth.
400
What is an axis?
It is an imaginary line running through Earth/Moon. It is titled and is the imaginary line that the Earth rotates around.
500
What is a solar prominence?
Huge loops of gases that extend out from the sun that are intense releases of energy.
500
Name all of the phases of the moon.
New Moon, Waxing Crescent, First Quarter, Waxing Gibbous, Full Moon, Waning Gibbous, Third Quarter, Waning Crescent
500
How would day/night change if earth's axis were straight up and down at a 180 degree angle?
We would still have day and night, but the sun would rise and set at the same time every day.
500
Why are summers in the Northern Hemisphere hot compared with the rest of the year?
The Sun's rays strike the Northern Hemisphere directly.
500
How would the seasons be affected if the Earth's axis were straight up and down at a 180 degree angle?
We would not experience seasons. The earth would have one season all year round because the sun would hit the Earth at the same angle all year.
