This is the motion of a planet in its orbit around the Sun.
What is Revolution?
100
This is the spinning of an object on its own axis.
What is Rotation?
100
These are the two seasons that begin on an equinox.
What is Spring and Fall?
100
This is the order of the seasons, starting with Winter.
What is Winter, Spring, Summer, and Fall?
100
This is the celestial object in the center of our Solar System.
What is the Sun?
200
It takes the Earth 24 hours to complete this motion.
What is Rotation?
200
This is the movement of an object around another object.
What is Revolution?
200
During an equinox the Sun's rays are more direct on this part of the Earth.
What is the Equator?
200
This is how Earth's axis is tilted during summer in the Northern Hemisphere.
What is towards the Sun?
200
These are the 3 criteria required to be classified as a planet.
1. Revolve around the Sun 2. Clear its orbit/path 3. Spherical shape
300
This is the degree at which planet Earth is tilted.
What is 23.5?
300
This is an imaginary line going through the North and South Pole of our Earth.
What is Axis?
300
During the Winter Solstice the Sun's rays are more direct on this part of the Earth.
What is the Southern Hemisphere?
300
When the Southern Hemisphere is tilted toward the Sun, St. Louis will be in this season.
What is Winter?
300
One Astronomical Unit (AU) is equal to the distance between which two celestial objects?
What is the Sun and Earth?
400
This is the direction planet Earth rotates (Use North, South, East, or West).
What is West to East (counter-clockwise)?
400
These words describe the position of Earth's axis. If Earth did not have this, we would not have seasons in St. Louis.
What is Axial Tilt?
400
During an equinox every place on planet Earth experiences this.
What is 12 hours of daylight and 12 hours of night?
400
These are the two things that cause our Earth to have seasons.
What is Revolution and Axial Tilt?
400
These are the 8 planets in order, starting with the planet closest to the Sun.
What are Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, and Neptune?
500
This is the direction the Sun "seems" to move across our sky.
What is East to West?
500
This is the imaginary path a planet takes as it revolves.
What is Orbit?
500
During an equinox the axis of the Earth is pointed in this direction (in relation to the Sun).
What is neither toward nor away from the Sun?
500
This is the reason why the equator is always hot and the poles are always cold.
What is the angle at which Sunlight hits the Earth? (direct and focused at the equator...angled and spread out at the poles)
500
This is the streak of light seen when a space rock enters our atmosphere. This is also known as a "shooting star."
