Day and Night Seasons Solar System Gravity Distances

100

What is the earth rotating on its axis?
The Sun (and stars) appear to rise in the East and set in the West every day because of this.

100

What is the Earth's tilt that causes the intensity/directness of the light to change?
This is the reason for the seasons.

100

What is Sun Jupiter Earth Moon?
This is how the following objects are ordered Largest to Smallest. Earth Moon Sun Jupiter

100

What is Mercury?
This is the planet with the fastest orbit around the sun.

100

What is an astronomical unit?
The distance from the Earth to the sun.

200

What is rotates, 24, and day (or rotational period)?
Planet Earth ________________ once around its axis every ________________ hours. We call this period of time a _____________.

200

What is Spring or Fall?
The Earth is not tilted toward or away from the sun during this season.

200

What is one?
This is the number of stars in our solar system.

200

What is mass and distance?
These are the two things that change the amount of gravitational force between two objects.

200

What is a light year?
We use this unit to measure distances between stars.

300

What is 365 and 1/4?
The number of times the Earth rotates during one orbit of the Sun.

300

What is summer?
In the Northern hemisphere, the sun is high in the sky during this season.

300

What is (your age)?
This is the number of trips you have made around the sun.

300

What is your weight on the moon is 1/6 of Earth because there is less gravity on the moon.
This how your weight on Earth compares to your weight on the moon and why.

300

What is an astronomical unit?
The best unit to measure the distance between Pluto and Mercury.

400

What is midnight?
If it is noon where I am, this is the time on the opposite side of the Earth.

400

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.
The seasons in the Northern Hemisphere are different than the Southern Hemisphere because of this.

400

What is between Mars and Jupiter?
The asteroid belt is located here.

400

What is Mars? This is because Mars has the longest period of revolution since it is furthest from the sun.
Of the inner (terrestrial planets), this one has the longest year and why.

400

What is it is much closer than the other stars, so it appears to be much bigger?
The sun appears bigger than all the other stars in the sky because of this reason.

500

What is noon, because the sun would still be shining on the same section of the Earth?
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.

500

What is summer and December?
When the Northern Hemisphere is leaning away from the Sun, the season is __________ in the Southern Hemisphere and the month is ____________.

500

What are: it's temperature range it's atmosphere it has water it's distance from the sun (2 chosen)
These are two of the reasons that Earth is more favorable to sustain life than other planets in the solar system.

500

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.
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.

500

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.
Put these objects in the order from closest to furthest from Earth: Alpha Centauri, Saturn, moon, sun, asteroid
