Sun Features

Which part of the sun is best described by the characteristics listed below:

- extending more than one million kilometers from its surface.
- temperature can reach two million degrees
- solar winds originate

• prominences

• sunspots

• solar flares

• corona

The photo shows a bright, looping projection which extends from the surface of the sun. This projection is called the

• coronal mass ejection

• solar winds

• solar flare

• solar prominence

Dark spots that are visible on the surface of the sun that are caused by intense magnetic activity that disrupts convection forming areas of reduced surface temperature.

• solar winds

• solar flares

• solar prominences

• sun spots

This is the lowest layer of the sun's atmosphere, and emits the light we see. It is about 300 miles (500 km) thick, although most of the light comes from its lowest third.

• aurorae

• solar winds

• solar prominences

• photosphere

Why are sunspots darker than the surrounding areas?

• The hotter gas releases less light

• The Cooler gas releases less light

• They look that way because the light form the sun 

• They are created by shadows from the moon.

Maya noticed some dark spots on the sun through her telescope. Why are these sunspots darker than the surrounding areas?

• The hotter gas releases less light

• The Cooler gas releases less light

• They look that way because the light form the sun 

• They are created by shadows from the moon.
