Motion in Space
The length of time it takes for Earth to complete one full rotation on its axis.
What is 24 hours?
Earth's axis of rotation is tilted at this specific angle.
What is 23 degrees?
How many times does the Moon rotate on its axis as it revolves around Earth?
What is once?
The motion of one body around another, such as Earth in its orbit around the Sun
What is revolution?
Earth's day and night is caused by ______
What is Earth's rotation on its axis?
Sunlight is least concentrated at these regions on Earth because the rays strike almost parallel to the surface.
What is the poles (North and South)?
How long does the Moon's rotation and revolution take?
What is about 27 days?
An imaginary line about which a turning body, such as Earth rotates.
What is axis of rotation?
Earth's path around the sun is in the shape of a(n) _____.
What is an ellipse?
During this event, sunlight shines equally on both the Northern and Southern Hemispheres.
What is equinox?
What is the near side of the Moon vs. the far side?

one part of a pattern of temperature changes and other weather trends over the course of a year.
What is season?

Compare and contrast Lunar highlands and Lunar maria.
A Mare is a large, dark plain of solidified lava on the Moon. Highlands are light colored areas that are higher than the maria.
This phenomenon occurs because the Moon takes the exact same amount of time to rotate on its axis as it does to orbit Earth.
What is only seeing one side of the Moon from Earth?

What is the equator?
According to scientists, the Moon's small, dense center core is largely composed of this metal.
What is iron?
What is the difference between the solstice and equinox?
A solstice is when the concentration of sunlight is higher at one hemisphere which results in longer days, while the other hemisphere gets minimum sunlight and results in longer nights. Equinox is when sunlight shines equally on the hemispheres and day and nights are almost equal for most of the Earth
