Phases of the Moon
This is the phase when the Moon is completely dark from Earth’s perspective.
What is the new moon?
The Earth experiences different seasons because it has this tilt on its axis.
“What is 23.5 degrees?”
This type of eclipse happens when the Moon passes between the Earth and the Sun.
“What is a solar eclipse?”
The rise and fall of ocean water caused mainly by the Moon’s gravity is called this.
“What are the tides?”
The Earth takes this long to rotate once on its axis.
“What is 24 hours?”
This phase occurs when the Moon is fully lit up as seen from Earth.
“What is the full moon?”
When it is summer in the Southern Hemisphere, it is this season in the Northern Hemisphere.
“What is winter?”
This type of eclipse happens when the Earth blocks sunlight from reaching the Moon.
“What is a lunar eclipse?”
These tides occur when the Sun, Earth, and Moon are in a straight line, producing the highest high tides.
“What are spring tides?”
The Earth takes about this long to orbit the Sun once.
“What is 365 days / 1 year?”
This phase is halfway between a new moon and a full moon, when exactly half of the Moon is lit.
“What is the first quarter or last quarter?”
This season occurs when the Earth’s tilt makes the Sun’s rays hit most directly on the Tropic of Cancer.
“What is Northern Hemisphere summer?”
This part of the shadow during a solar eclipse is the darkest, where a total eclipse can be seen.
“What is the umbra?”
These tides occur when the Sun and Moon are at right angles, producing weaker tides.
“What are neap tides?”
These regions of the sky are divided into 24 time zones across the Earth.
“What are longitudes?”
In the Southern Hemisphere, the Moon is lit on the left side when it is in this quarter phase.
“What is the first quarter moon?”
Day and night are approximately equal in length during these times of year.
“What are the equinoxes?”
A solar eclipse can only happen during this phase of the Moon.
“What is a new moon?”
The Earth experiences this many high tides and low tides in about 24 hours.
0: The Earth experiences this many high tides and low tides in about 24 hours.
→ “What is two high tides and two low tides?”
This is the term for a star that is the centre of our solar system.
“What is the Sun?”
This phase comes just before the new moon, when only a thin slice on the left side is visible from the Southern Hemisphere.
“What is the waning crescent?”
If the Earth’s axis were not tilted, we would not have these changes in the year.
“What are the seasons?”
A lunar eclipse can only happen during this phase of the Moon.
“What is a full moon?”
The difference in water levels between spring tides and neap tides happens because the Sun’s gravity does this to the Moon’s pull.
“What is it can add to or partly cancel out the Moon’s pull?”
This galaxy contains our solar system and billions of other stars.
“What is the Milky Way?”
