What is the imaginary line that the earth spins on?
Axis
How does a new moon look?
All dark/black
What is the movement of the earth on its axis called?
Rotate/rotation
How many days does it take for the Earth to orbit the sun?
365 1/4
What causes the
seasons?
The tilt of the Earth's axis.
The tilt of the Earth's axis is responsible for our seasons. At what degree does the earth tilt?
23.5 degrees
How does a full moon look?
All lit up or white
What is the movement of the Earth around the sun called?
Orbit/Revolution/Revolve
How long does it take Earth to rotate once on its axis?
24 hours
Why do the northern and southern Hemispheres have opposite seasonal experiences?
The Earth's tilt causes this. When one hemisphere is tilted towards, the other is tilted away.
What causes the cycle of the seasons?
The Earth's tilt on its axis.
How often does the moon's phase pattern repeat?
Every 28-29 days
What is it called when the sun is shining directly on the equator and the Northern Hemisphere has equal amounts of daylight and night?
Equinox
When it is day on one side of the Earth, what is happening on the other side of Earth?
When one side of Earth faces the sun, it is day. The side of Earth that isn't facing the sun is experiencing night.
In the picture, which number is the northern hemisphere in summer?
1
When it is the winter in the southern hemisphere, which hemisphere is tilted towards the sun?
Northern
If more than half of the moon is visible, what is it called?
Gibbous
What is the imaginary line that runs around the centre of the earth?
Equator
Earth's rotation makes the sun look like it is moving. What is actually moving?
The earth is orbiting around the sun.
The earth travels in an oval around the sun so it is closer to the sun at some points and further from the sun at other times. When the earth is closer to the sun, does the Earth experience summer? why or why not?
No, because it is the tilt of the Earth that determines our seasons.
If it is summer in the northern hemisphere, which hemisphere is tilted away from the sun?
southern hemisphere
If more of the moon is visible each night, what is it called?
Waxing
The Earth is divided into two equal halves; one in the north and one in the south. What are these halves called?
Hemispheres
