Stars

Question 0

Chromosphere

Answer 0

• The layer of the sun atmosphere located above the photosphere.
• Hotter than photosphere, the presence of more helium gives it a red color.

Question 1

Photosphere

Answer 1

• Lowest layer of the suns layer, appears as the visible surface of the sun.
• Most of the light from the sun comes from this layer.

Question 2

Corona

Answer 2

The outermost layer of the sun.

Question 3

Core

Answer 3

The center of the sun. Where the energy is produced.

-despite density, the suns interior remains gaseous because if it’s high temps.

Question 4

Radiative zone

Answer 4

The region above the core where Energy is transferred from gas particle to gas particle.

Question 5

Convective zone

Answer 5

Lies above the radiative zone,

-where the suns energy is carried the rest of the way to its surface by convection currents.

Question 6

E=mc squared

Answer 6

Albert einstiens equation that explains that matter can be converted into energy.

Question 7

Fusion

Answer 7

The combining of lightweight nuclei, into heavier nuclei.

• in the suns core, helium is the product of fusion of hydrogen nuclei.
• the helium that’s formed with the hydrogen nuclei has a mass that’s less than the mass of the hydrogen.

Question 8

Sunspots

Answer 8

Dark, cooler patches on the surface of photosphere.

• They are located in areas where the suns magnetic field prevents hot gases from rising to the surface,
• maximum number of the occur every 11.2 years

Question 9

Solar flares

Answer 9

Violent eruptions of particles and radiation from the suns surface.

Question 10

Solar winds

Answer 10

Made up of gas flowing outward from the corona.

-carry solar flares charged solar particles to all planets in the solar system

Question 11

Auroras

Answer 11

A spectacular light display that occurs when the sun and the charged particles from the sun collide

Question 12

Prominence

Answer 12

An arc of gas that shoots up from the chromosphere.
