These are a cooler, dark
areas on the sun’s surface
Sunspots
The “power source” of the
sun.
Core

layer” of the sun
Photosphere
The dark and lighter regions
of a sunspot are called
________ and ________.
Umbra and penumbra
Electrically charged particles
that affect Earth’s climate,
radio transmissions, and
create auroras.
Solar wind

becoming a giant star.
Cooler regions of the Sun’s
surface
Sunspots
Darkest region of a sunspot
