Sun and Auroras
How does the sun make energy?
The smallest planet that is also closest to the sun.
Mercury
What is the name of the force that keeps the moon in orbit around the earth?
Gravity
I am made of rock and ice and get a tail when I approach the sun.
Comets
What is the stream of small particles and radiation that is emitted by the sun called?
Solar Winds
Known as the red planet. Closest planet to earth.
Mars
True or False. The force of gravity is stronger on earth than it would be on Jupiter.
False
Which planets are larger: Terrestrial or Jovian?
Jovian
What are shooting stars?
Meteors.
What protects our planet from the solar winds?
The Magnetosphere
The planet known for having rings.
Saturn
Why do we feel the force of gravity caused by the earth more than the force of gravity caused by the sun?
We are closer to the earth.
Name of the belt of asteroids found at the edge of our solar system.
Kuiper Belt
When a meteor hits the ground it is called a __________ and makes a ___________.
Meteorite; crater or astrobleme
Name the 2 auroras found on our planet.
Aurora Borealis and Aurora Australis
This planet is the largest in the solar system and has a giant storm that has lasted hundreds of years.
Jupiter
True or False. There is a small force of gravity between you and the book on the table.
True.
Name of the asteroid/comet field that surrounds our solar system.
Oort Cloud
True or False. A comet's tail points towards the sun.
False. It points away because solar winds destroy the comet.
Describe how polar auroras are formed starting from the sun.
Solar wind emited by the sun is redirected to the poles by the magnetoshphere. Here it interacts with particles in the thermosphere creating light.
This planet takes longer to complete one rotation than it takes to go around the sun once. (Days are longer than years)
Venus
Who is the scientist who came up with the theory of gravity?
Newton
Write the planets in their correct order.
Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, Neptune
Asteroid, Meteoroid, Meteor, Meteorite
Asteroid = big rock in space
Meteoroid = Smaller rock in space
Meteor = Small rock in the atmosphere
Meteorite = Small rock that hit the ground
