rotation
The imaginary line that passes through the North and South Poles.
the axis of rotation
The object that comes between the Sun and Earth during a solar eclipse.
The Moon
The time Earth takes to complete one revolution around the Sun.(if not leap year)
About 365 days
The direction Earth rotates when viewed from above the North Pole.
Anti‑clockwise (West to East)
The object that blocks sunlight from reaching the Moon.
Earth
The motion of an object around another object.
Revolution
The eclipse where the Moon completely blocks the Sun.
Total solar eclipse
The path Earth follows around the Sun.
Orbit
The cycle caused by Earth’s rotation.
Day and night
The eclipse where only part of the Moon is in Earth’s shadow.
Partial lunar eclipse
The reason the Sun appears to rise in the East and set in the West.
Earth’s rotation
The reason the Moon can cover the Sun even though it’s smaller.
Their apparent sizes are similar
The reason the stars seen at night change over the year.
Earth’s revolution
The star that appears nearly stationary in the night sky.
The Pole Star
The rare event where Venus appears as a tiny dot crossing the Sun.
Transit of Venus
The reason seasons occur on Earth.
Earth’s tilted axis. (half mark if answer is only revolution)
what is the reason the Sun, Moon, and stars all appear to move across the sky even though they are not actually moving that way.
Because we observe them from a rotating Earth.
This is the reason a total solar eclipse is visible only from a very small region on Earth.
Because the Moon’s umbra (its darkest shadow) is very narrow when it reaches Earth.
This is the reason the North Pole experiences six months of daylight followed by six months of darkness.
Because Earth’s tilted axis keeps the North Pole pointed toward the Sun for half the orbit and away from it for the other half.
