The Sun (and stars) appear to rise in the East and set in the West every day because of this.
What is the earth rotating on its axis?
100
This is the reason for the seasons.
What is the Earth's tilt that causes the intensity/directness of the light to change?
100
This is how the following objects are ordered Largest to Smallest. Earth Moon Sun Jupiter
What is Sun Jupiter Earth Moon?
100
This is the planet with the fastest orbit around the sun.
What is Mercury?
100
The distance from the Earth to the sun.
What is an astronomical unit?
200
Planet Earth ________________ once around its axis every ________________ hours. We call this period of time a _____________.
What is rotates, 24, and day (or rotational period)?
200
The Earth is not tilted toward or away from the sun during this season.
What is Spring or Fall?
200
This is the number of stars in our solar system.
What is one?
200
These are the two things that change the amount of gravitational force between two objects.
What is mass and distance?
200
We use this unit to measure distances between stars.
What is a light year?
300
The number of times the Earth rotates during one orbit of the Sun.
What is 365 and 1/4?
300
In the Northern hemisphere, the sun is high in the sky during this season.
What is summer?
300
This is the number of trips you have made around the sun.
What is (your age)?
300
This how your weight on Earth compares to your weight on the moon and why.
What is your weight on the moon is 1/6 of Earth because there is less gravity on the moon.
300
The best unit to measure the distance between Pluto and Mercury.
What is an astronomical unit?
400
If it is noon where I am, this is the time on the opposite side of the Earth.
What is midnight?
400
The seasons in the Northern Hemisphere are different than the Southern Hemisphere because of this.
What is the tilt of the Earth? The seasons are opposite of each other--when the Northern hemisphere is in summer, the Southern hemisphere is in winter.
400
The asteroid belt is located here.
What is between Mars and Jupiter?
400
Of the inner (terrestrial planets), this one has the longest year and why.
What is Mars? This is because Mars has the longest period of revolution since it is furthest from the sun.
400
The sun appears bigger than all the other stars in the sky because of this reason.
What is it is much closer than the other stars, so it appears to be much bigger?
500
If it is noon where you are in North America, this is the time would it be at a location directly south of you, below the equator.
What is noon, because the sun would still be shining on the same section of the Earth?
500
When the Northern Hemisphere is leaning away from the Sun, the season is __________ in the Southern Hemisphere and the month is ____________.
What is summer and December?
500
These are two of the reasons that Earth is more favorable to sustain life than other planets in the solar system.
What are: it's temperature range it's atmosphere it has water it's distance from the sun (2 chosen)
500
These are the two forces that keep satellites and planets in orbit and the explanation what you would need to do to put a satellite in a lower orbit around the Earth.
What is gravity and inertia? Inertia has an object wanting to keep doing what it's doing. Gravity is pulling the two objects together. These two forces work like a tug of war to keep a satellite in orbit. So, satellites in lower orbits have to go faster to stay in orbit.
500
Put these objects in the order from closest to furthest from Earth: Alpha Centauri, Saturn, moon, sun, asteroid
What is the moon, sun, asteroid, Saturn, Alpha Centauri? Note: The main asteroid belt lies between 1 and 4 AU from Earth--so, depending on where you are, the asteroids may be the same distance as the sun.
