The most striking example of solar sunspot variability was the -

Maunder Minimum from 1645-1715.

The correct order, from the center moving outward, for the major regions of the Sun is -

core, radiation zone, convection zone, photosphere, chromosphere, corona

The outer atmosphere of the Sun is called the -

corona

The term 'CME' is an acronym for -

coronal mass ejection

The pattern of rising hot gas 'cells' all over the photosphere of the Sun is/are called -

granulation.

Sunspots are regions with -

strong magnetic fields.

Solar flares usually erupt from -

sunspot regions

The temperature of the Sun's surface is approximately -

10,000 degrees F

About how long is the average 'solar' cycle?

11 years (says its 22 but no)

the core of the Sun is composed of what type of matter?

Plasma

Stellar composition is determined by which of the following?

Spectroscopy

How does the Sun's mass compare to the mass of the Earth?

The Sun's mass is about 300,000 times the mass of the Earth.

The light we actually 'See' from the Sun comes from which layer?

The photosphere

Why are solar storms dangerous to our way of life here Earth?

They can disrupt electrical grids and sensitive satellite electronics.

What happens to the magnetic fields of the Sun once every 11 years?

They experience a polarity flip.

The time between consecutive sunspot maxima is about -

a decade

month

Approximately how many Earth's could fit inside the Sun -

over 1,000,000

The majority of the solar wind escapes from the Sun through -

regions called coronal holes.

When taking into account all regions of the Sun, from the core to the corona, which regions contains the highest temperatures?

the core

Sunspots appear darker than the rest of the Sun's surface because -

the surrounding areas are much brighter.

What type of star is the Sun?

yellow dwarf
