Planets (Terrestrial vs Jovian)
Which planet is the smallest in our solar system?
Mercury
What is the Axis?
An imaginary line going straight through the North and South poles.
What is Mass? And does is change on different planets?
The amount of matter (or "stuff") in an object. No it does not change, you are always made of the same amount of stuff/matter.
What does ISS stand for?
International Space Station
What is the hottest planet is our solar system?
Venus, due to its extremely thick atmosphere.
List all 8 planets in order (closest-farthest)
Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, Neptune
What is a Revolution?
A revolution is earth completely travelling around the sun. Take 365 days (1 year) Works with earths tilt to create our seasons.
What is Weight?
Weight is the force of gravity pulling down on an object.
In what year did humans first land on the moon?
Humans first landed on the moon in 1969 (Apollo moon landing)
Which planet is the largest? Which Planet rotates on its side, like a barrel rolling through space.
Jupiter and Uranus.
What is the difference of Terrestrial and Jovian planets?
Terrestrial Planets; Rocky surfaces, smaller in size, closer to the sun. Jovian Planets; Massive Gas Giants, Made of gas/ice (not solid), Further from the sun.
How many degrees is earth tilted?
23.5 Degrees
On which planet would you weight the most?
Jupiter
Why do scientist keep sending rovers to mars?
Mars is too dangerous for humans right now. Rovers are sent to test soil and search for signs of life, scientist believe life may have once existed on Mars.
Which two Planets Atmospheres are made up mostly of Hydrogen, Helium, and Methane
Uranus and Neptune
Which Planet has a very thick, hot and toxic atmosphere with sulphuric acid clouds?
Venus
What is a roatation?
A rotation is earth spinning on it axis. Takes 24 hours. Creates day and night.
What unit is Mass and Weight measured in?
Mass - Kg
Weight - N (Newtons)
What is the ISS? (International Space Station)
A giant orbiting space lab where astronauts from around the world live while in space.
Explain the difference between weight and mass.
Mass is the amount of matter/stuff something is made up of. While weight is the force of gravity pulling down on that matter.
What are the two main components that make up Jupiter and Saturns atmosphere?
Hydrogen and Helium
Explain how earth tilt and revolution creates our season.
As earth revolves, this tilt causes different hemispheres to receive more (or less) direct sunlight. This is why we have Winter, Spring, Summer, and Fall.
Does you weight change on different planets? Explain.
YES, your weight does change on different planets. The reason for this is because each planet has a different force of gravity pulling on you. (Jupiter have the most gravity, so you weigh the most there)
What is the Hubble Space Telescope? And what is its purpose?
Hubbles is a massive telescope launched into earth orbit. It takes perfectly clear pictures of deep space, helping discover new galaxies.
How do we measure Mass and Weight?
Mass - Balance Scale
Weight - Spring Scale
