The Sun
What is the order of the layers of The Sun? (inside to outside)
Core, radiative zone, convection zone
What are the formulas to get wavelength, speed and frequency?
speed=wavelength x frequency
wavelength= speed/frequency
Frequency=speed/wavelength
What depends on The Earth's tilt?
Seasons depend on Earth's tilt and how the light hits The Earth.
Why does Jupiter have a stronger pull than The Earth?
Jupiter has more mass than The Earth.
What does Galileo do?
Galileo uses telescope to make observations.
How long does it take for light to travel from the surface of The Sun to Earth?
8 minutes
What are transverse and longitudinal waves?
Transverse waves don't need a medium and an example is light and longitudinal waves need a medium and an example is sound. Transverse waves are also electromagnetic waves and longitudinal waves are also mechanical.
How long does it take for The Earth to turn in a circle?
24 hours
Why do we have less weight when we are in space?
What does Copernicus do?
Copernicus makes a model that shows The Sun in the center of the solar system.
What is the energy that The Sun sometimes shoots out which is a solar storm?
A solar flare
What is a rarefraction and compression?
A rarefraction is an area where material through a longitudinal wave is spread apart and a compression is when its pressed together.
How many days is a circle around The Sun?
365 1/4 days
If you are far away enough, do we not have gravity with The Sun anymore?
We always have gravity with The Sun.
What does Aristarchus do?
Aristarchus is the first to say that The Sun is at the center of the solar system.
What happens to The Sun when it is more likely to create more solar storms? What is the time they appear more called?
Sunspots and the solar maximum.
What is amplitude?
Amplitude is when a wave is higher.
When a solar flare collides with The Earth's upper atmosphere and we see the Northern and Southern lights, what is that also called?
An Aurora
Why does satellites and the moon not crash into The Earth?
They are moving fast enough to stay in orbit.
What does Herschel do?
Herschel discovered how to use prisms to separate colors and see see their temperatures.
What does The Sun use nuclear fusion to do?
Uses nuclear fusion to create energy to turn hydrogen into helium.
What is the colorific scale and what is the heat and wavelength of them?
The colorific scale is when the light from The Sun shines on color lenses and you see that 1 color and red has a warmer temperature than violet and unlit colors above red are warmer but ultraviolet is also warmer.
What does The Sun give us energy for?
The Sun gives us energy for wind, ocean currents and the water cycle.
Do we get pulled to The Earth or does The Earth get pulled to us?
Both objects get pulled to each other but we get pulled more because The Earth has more mass.
What did Newton do?
Newton made his 3 laws of motion.
