Unit 2 - Week 2

Question 1

The center of the sun. This region is extremely hot and dense

Answer 1

Core

Question 2

The layer of the sun that gives off visible light. Part of the sun’s atmosphere.

Answer 2

Photosphere

Question 3

Areas of gas on the sun’s surface that are cooler than the gasses around them. This is caused by the sun’s magnetic field

Answer 3

Sunspots

Question 4

Reddish loops of gas that link parts of sunspot regions

Answer 4

Coronal loops / Prominences

Question 5

The layer of the sun’s atmosphere that looks like a halo during a solar eclipse. This region is responsible for generating solar wind.

Answer 5

Corona

Question 6

The layer of the sun’s atmosphere that has a reddish glow. Only visible during a solar eclipse.

Answer 6

Chromosphere

Question 7

The process where hygrogen atoms collide to form helium atoms, creating electromagnetic energy in the process

Answer 7

Fusion

Question 8

The layer of the sun’s interior where energy is transfered mainly by electromagnetic radiation.

Answer 8

Radiation zone

Question 9

A stream of charged particles produced by the corona. Responsible for creating the aurora borealis (northern lights)

Answer 9

Solar wind

Question 10

The outermost later of the sun’s interior where gasses circulate between hot and cold regions.

Answer 10

Convection zone

Question 11

Eruptions of particles and radiation from the surface of the sun.

Answer 11

Solar flare

Question 12

What is the hottest layer of the sun?

Answer 12

Core

Question 13
