Vocabulary
100
Nuclear fusion produces this in the sun.
What is energy?
100
photosphere, chromosphere, and the corona
What are the three layers of the sun?
100
This is known as the dark spots on the sun's surface
What are sun spots?
100
These are reddish loops of gas that are groups of sunspots.
What are prominences?
100
The process by which hydrogen atoms join together to form helium, releasing energy
What is nuclear fusion?
200
Nuclear fusion occurs only under these conditions.
What is extremely high temperature
200
When you look at the image of the sun, this is what your are looking at.
What is photosphere
200

Why do sunspots look darker than the rest of the photosphere?

What is because they are cooler than the surrounding gasses?

200

Streams of particles/gas ejected from sunspots

What are solar flares?

200
The center of the sun
What is the core
300
Nuclear fusion occurs here.
What is the core?
300
This is a reddish glow around the photosphere.
What is the chromosphere?
300
The amount of energy produced on the sun (increase or decrease) causes more or less of these.
How do the number of sunspots vary over time?
300

Huge amount of material ejected when from a prominence?

What is coronal mass ejection (CME)?

300

The "surface" layer of the sun

What is photosphere?

400
Light that gradually moves from the sun's core to it's atmosphere, and is then heated before it moves to space produces this for the Earth.
What is energy?
400
Looks like a white halo. It also means "crown" in Latin.
What is the corona?
400
The amount of energy the sun produces may be linked to the number of these.
What is the number of sunspots?
400

How does solar wind affect the Earth's atmosphere?

What are cause magnetic storms, electrical problems for homes and businesses?

400

Chromosphere

What is the layer surrounding the photosphere?

500

Plasma heats up and rises, then cools and sinks in a repeating cycle in this zone of the sun

What is the convective zone?

500
Solar wind enter the Earth's atmosphere here.
What are the North and South poles?
500
The number of these may cause changes to the Earth's temperature.
How do sunspots affect the Earth's climate?
500

The stream of particles constantly ejected from the corona

What is solar wind?

500

This is the element that hydrogen fuses into in the core

What is Helium?
