Layers of the sun
What are the First 3 layers of the sun and a bit about them
Core: inner most layer, nuclear fusion takes place, the hottest layer.
Radiative zone: Energy travels through VERY slowly
Convection: Heated particles rise and cooler particles fall
Where does it takes place
The core of the sun
Where are all stars born
The Nebula
What is the Big Bang?
Everything that is now in the Universe was squeezed into a point. a single, hot, chaotic mass. Then an enormous explosion took place. The big bang caused the Universe to start expanding rapidly. All the matter and energy, even space itself, came out of this explosion
What are the molecules in the sun?
Hydrogen and helium
What are the next 3 layers of the sun and something about them?
Photosphere: Coolest layer and the one we see
Chromosphere: thinnest layer and it glows red
Corona: outer most layer, thickest layer, and visible during the solar eclipse
What two molecules combine to make helium
Hydrogen and hydrogen
What does a star become after it is in the nebula?
A Main sequence star
In the first few moments after the Big Bang, the Universe was unimaginably hot and dense. it became less dense and began to cool. protons, neutrons, and electrons could form. After a few minutes, hydrogen came together. There was so much energy that nuclear fusion began. This created helium. Clumps of matter were held together by gravity. The
What is the first layer and last layer of the sun?
The core and the corona
What layer of the sun is the biggest
The Corona
What two molecules combine to make energy
Hydrogen and helium
What is the life cycle of a small-medium star?
Nebula ➡️ Main sequence ➡️ Red giant ➡️ White dwarf. Ran out of hydrogen to burn off of
What is back ground radiation?
The little amount of heat left over from the Big Bang
Did everyone immediately agree with the Big Bang theory?
No
What are the 6 layers of the sun in order
Core
Radiative
Convection
Photosphere
Chromosphere
Corona
How does energy get to Earth
It goes through the layers
What is the life cycle of a Large star?
Nebula ➡️ Main sequence star ➡️ Red super giant ➡️ super nova ➡️ Nebula
What does background radiation have to do with the Big Bang?
the space between objects should have no heat at all. The temperature should measure 0 Kelvin. But two researchers at Bell Laboratories used a microwave receiver to measure the background radiation in the Universe. They discovered that it is not 0 K, but 3 K.
Does everyone currently agree with the Big Bang theory?
No
What happens in the Radiative and Convection zone layers of the sun
Radiative: Energy travels VERY slowly
Convection: hotter particles rise and cooler ones fall
How often does nuclear fusion occur? Why?
A LOT. Because of the small space and many fast pace molecules moving around and colliding
What are some things about Large stars that small stars don’t have?
Iron, gold, silver, uranium, and carbon. It burns faster because it is bigger. Turns into a Nebula. super nova.
How many years ago is it estimated that the universe started?
13.7 billion years ago
How many layers of the sun are there?
Six
