What is the Moon's role in relation to Earth?
The Moon is a natural satellite of Earth.
The Moon is a planet orbiting Earth.
The Moon is a star near Earth.
The Moon is an artificial satellite of Earth.
The Moon's radius is (a) km. (the Earth’s radius is 6300 km).
The Sun’s radius is (a) km, which is 400x bigger than the Moon.
The Sun is 400x further away than the Moon, so both are almost the same (a) in the sky.
What happens when the Moon slides in front of the Sun in the sky?
A solar eclipse occurs
A lunar eclipse occurs
The Sun becomes brighter
The Moon disappears
What is a solar eclipse and how does it differ from an annular eclipse?
A solar eclipse occurs when the Moon completely covers the Sun, while an annular eclipse occurs when the Moon covers the Sun's center, leaving a ring-like appearance.
A solar eclipse occurs when the Moon partially covers the Sun, while an annular eclipse occurs when the Moon completely covers the Sun.
A solar eclipse occurs when the Earth comes between the Sun and the Moon, while an annular eclipse occurs when the Moon comes between the Sun and the Earth.
A solar eclipse occurs when the Sun is completely visible, while an annular eclipse occurs when the Sun is partially visible.
Why does a solar eclipse not happen every orbit of the Moon?
The Moon's orbit is tilted relative to Earth's orbit around the Sun.
The Moon is too far from Earth to cause an eclipse every orbit.
The Sun is too far from Earth to be eclipsed every orbit.
The Earth's rotation prevents frequent solar eclipses.
What conditions are necessary for an eclipse to occur?
The Sun, Earth, and Moon must be aligned
The Earth must be closer to the Sun
The Moon must be full
The Sun must be at its highest point
Why do lunar eclipses happen more often than solar eclipses?
Lunar eclipses occur when the Earth is between the Sun and the Moon, which happens more frequently.
Solar eclipses require a precise alignment of the Sun, Moon, and Earth, which is less common.
The Earth's shadow is larger than the Moon's shadow, making lunar eclipses more frequent.
Lunar eclipses can be seen from anywhere on the night side of Earth, while solar eclipses are visible only in a narrow path.
What are the two ways to measure the Moon's orbit around the Earth?
Sidereal month and synodic month
Lunar month and solar month

How does the Moon appear to move as it orbits the Earth?
The Moon appears to move from east to west across the sky.
The Moon appears to move from west to east across the sky.
The Moon appears to remain stationary in the sky.
The Moon appears to move randomly across the sky.
How many degrees does it move in 24 hrs?
(a)
The mean diameter of the Earth is (a) .
The (a) of the Earth are the north and south pole.
Map lines dividing the Earth from north to South (like the segments of an orange) are called (a) .
All lines of longitude are exactly the (a) because they all run from the North pole to the south pole.
The longitude system has a zero line that runs through the (a) .
The longitude of any place is then measured in degrees to the east or to the west, using the (a) made at the Earth’s centre by the PM to the location in question.
The Earth’s (a) defines a second set of lines that rise in parallel circles above or below the equator called lines of latitude.
Latitude is measured in degrees up or down from the equator, giving the N and S poles a latitude of (a) .
Lines of latitude are not all the same size. Zero degrees (the equator) is the longest (40 000 km). The length of 89 degrees north (or south) is only (a) .
The Earth’s axis of rotation is (a) relative to the plane of its orbit at about 23.5 degrees.
This means that in UK summer, the north pole leans towards the (a) , but in UK winter, the south pole is the one pointing towards the sun.
The effect of this is that the sun is only directly above the equator (a) a year at the equinoxes (21st March, 23rd September).
The latitude furthest north the Sun gets overhead (on only one day of the year – June 22nd) is called the (a) . This is 23.5 degrees north.
The southern equivalent is called the (a) , and the Sun gets here on December the 21st.
Near the poles, there is a critical latitude where the sun stays up for 24 hours when that pole is leaning towards the sun. These are the (a) . Both have a value of 66.5 degrees.

It has no effect on the occurrence of eclipses.
It causes the Moon to appear larger in the sky.
Why does the Moon seem to move eastwards against the stars in the background?
Because the Moon orbits the Earth in the same direction as the Earth's rotation.
Because the stars are moving westwards faster than the Moon.
Because the Earth's rotation makes the Moon appear to move eastwards.
