The __________________ is the "visible" surface of the Sun, made of a thin layer of strongly ionized gas. This is where the sunlight is emitted.

• corona

• prominences

• sunspots

• photosphere

The _____________ is the outer atmosphere of the Sun. It extends many thousands of kilometers (miles) above the visible "surface" of the Sun, gradually transforming into the solar wind that flows outward through our solar system.

• corona

• prominences

• sunspots

• photosphere

_____________ are dark, planet-sized regions that appear on the "surface" of the Sun. Sunspots are "dark" because they are cooler than their surroundings.

• corona

• prominences

• sunspots

• photosphere

Large loop-like structures on the edge of the solar disk sometimes stand out brightly against the dark background of space. These enormous structures are called solar ____________________.
