​Solar Prominence

​A prominence is a bright, relatively dense, and relatively cool arched cloud of gas in the chromosphere and corona of the Sun. Looks like a Loop.

​

​

​Solar Flares

​A solar flare is a sudden, brief (typically lasting only a few minutes), and explosive release of solar magnetic energy that heats and accelerates the gas in the Sun's atmosphere.

Solar flares are brief explosions of solar magnetic energy.

​What is happening in space

​What we see

Multiple Choice

Prominences and sunspots are both:

• Jets of burning gas

• Patches on the Sun's surface

• Caused by the Sun's electromagnetic field

• Visible

Multiple Select

Which of the following correctly describes the rotation of the Sun?

• All parts of the Sun rotate together.

• The Sun rotates faster at its equator than at its pole.

• The Sun rotates slower at its equator than at its pole.

• The Sun does not rotate at all.

Earth's energy budget allows us to track how much energy is coming in and going out. ​Incoming solar energy is either: Reflected or Radiated back to space, or Absorbed.  About 71% of the total incoming solar energy is absorbed by the Earth system.
