Moon Phases
Occurs when all of the Moon's Earth facing surface reflects light
Full Moon
A cloud of gas that is the birthplace of stars
Nebula
This takes 365 days or 525,600 minutes.
The earth's revolution around the sun
If a star has a luminosity of 10^-2 it is 100 times less bright than this.
Our sun.
These two things cause ocean tides.
The Moon and the Sun
A phase of the moon in which the left half of the moon is illuminated
Third Quarter or Last Quarter
A ball of plasma which produces nuclear fusion in its core.
A star
This causes different parts of the earth to experience day and night.
The Earth's rotation
The name of the phenomenon in which we can tell stars are moving farther away from us because their light waves are becoming longer.
Red Shift
The number of times we experience high tide in one day.
More than half of the left side of the moon is illuminated
Waning Gibbous
A spherical object which orbits a star whose gravity has cleared away any other objects of a similar size near its orbit.
A planet
This would occur if the earth had no tilt
No seasons
The stars which have the lowest temperature emit this colour of light.
Red
These are the moon phases during largest tidal range; Spring Tide.
Full Moon and New Moon
A phase of the moon coming after a new moon and before a 1st quarter moon that is a lit up crescent on the right.
Waxing Crescent
A system of billions of stars, gas and dust held together by gravity
Galaxy
This would occur if the earth's rotated twice as fast.
12-hour days
The most common type of star and how most stars will spend the majority of their life cycle.
Mid-sequence star
These are the moon phases of neap tide.
First Quarter and Last/Third Quarter
When the earth is directly between the moon and the sun
Lunar eclipse
A mass of dust and ice that orbits a star in an elliptical pattern
A Comet
If the north pole is tilting towards the sun, what season is it in Johannesburg, South Africa?
Winter
This will be the final phase of our sun
White Dwarf
The two types of tidal bulge
Tidal bulge due to gravity and tidal bulge due to inertia.
