Properties of the Sun

What are sunspots?

• the layer of the

  sun where hot plasma rises, then

  falls as it cools near the surface

• cool, dark spots appearing in groups on the

  surface of the Sun

• appears to move from left to right due to the rotation of the sun

• A large, bright, gaseous feature extending outward from the Sun’s surface, often in a loop shape

What is the Sun's convection zone?

• the layer of the

  sun where hot plasma rises, then

  falls as it cools near the surface

• cool, dark spots appearing in groups on the

  surface of the Sun

• • Thermal energy generated

  from the interior of the sun

  is moved towards the outer

  region

• A large, bright, gaseous feature extending outward from the Sun’s surface, often in a loop shape

What is prominence?

• the layer of the

  sun where hot plasma rises, then

  falls as it cools near the surface

• cool, dark spots appearing in groups on the

  surface of the Sun

• • the scorching, swirling plasma

  and chaotic magnetic fields

  within the Sun

• A large, bright, gaseous feature extending outward from the Sun’s surface, often in a loop shape

What is a low mass star?

• a star that has high luminosity, short-lived, big radius, blue

• a star that has low luminosity, long lived, small radius, red

The sun rotates at different speeds because it is made up of

Thermal energy generated from the_​ ​ (a)   of the sun is moved towards the _​ ​ (b)   region.

• interior
• outer
