Sun vocab

Question 1

Core

Answer 1

Nuclear core size of Jupiter but a lost denser it is 27 million degrees hot and is the center of the sun. Nuclear fusion occurs in the core.

Question 2

radiative zone

Answer 2

Energy from the core that radiates from the radiative zone it is 4.5 million degrees hot. Middle layer of the sun’s interior. Region that is very tightly packed where gas where energy is released in electromagnetic radiation

Question 3

convection zone

Answer 3

Sun is so dense it takes 1,000,000 years from energy from the core to reach surface. the convection zone is 2 million degrees hot. Outermost layer of sun’s interior. Hot gas rise from the bottom and gradually cools as it reaches the top of the zone. cooler gas sink, forming loops of gas that move heat towards the sun surface.

Question 4

photosphere

Answer 4

The layer of the sun the we can see and the layer that gives out light. It is 340 mile deep and is 10,000 degrees hot. Inner layer of sun’s atmosphere

Question 5

sunspots

Answer 5

When heat is rising to the surface magnetic field gets stirred up which created dark patches. It is 7,800 degrees hot. Areas of gases in the sun that is cooler than the gases around the spots. They occur in groups. they are about 7,8000 degrees

Question 6

Granules

Answer 6

A line that is 600 miles across the sun that occur because of when the gas rises and falls this line lasts for about eight minutes.

Question 7

Solar happenings

Answer 7

The solar activities that happens such as flares prominences and coronal loops, etc occur every day

Question 8

Corona

Answer 8

The outer layer of the sun atmosphere. Made up of thin gases and is about 1,000,000 miles high corona can only be seen in a solar eclipse. Temperature is about 4 million degrees hot.

Question 9

solar wind

Answer 9

Charged Particles that flies from the core in all direction. These particles can go as fast as 1,000,000 mph. These particles is essential for the corona to expand into space.

Question 10

chromosphere

Answer 10

A layer in the sun’s atmosphere that have a reddish glow which gives the sun it’s color. thickness is about 6,000 miles. Middle layer of sun’s atmosphere. Temperature is 50,000 degrees.

Question 11

Solar Flares

Answer 11

Outburst of energy that occur around sunspots as magnetic field tear apart and reconnect. Explosions from prominences. One can release 40 billion atomic bombs. They can greatly increase the solar wind

Question 12

Prominences

Answer 12

Arches of gas that releases between sunspots and link them. Leaps and leaps eventually off the sun’s surface and lasts for days until it disappears. Sometimes loops connect which releases a large amount of energy. The energy heats gas onto millions of celsius which causing gas to explode in space.

Question 13

Coronal Loops

Answer 13

Magnetic loops that contains very strong magnetic fields. They contain dense hot gas that sends x-ray radiation

Question 14

Coronal mass ejection

Answer 14

Solar eruptions CME grow larger than the sun and when directed towards earth it blocks communication and can damage satellites

Question 15

Nuclear fusion.

Answer 15

Hydrogen atoms combine to create helium which releases a massive amount of energy.
