Solar flares

• cause Earth's auroras at the poles.

• can cause damage to the ISS and satellites.

• increase charged particles in gases creating magnetic storms in Earth's atmosphere.

• can disrupt radio, telephone and television signals.

Moving areas of magnetic activity with temperatures that are cooler than the area of the photosphere

• Photosphere
• Corona
• Sunspots
• Prominence

What is a solar wind?

• The surface of the sun

• Darker, cooler areas of the sun

• Outer layer of the sun

• Constant flow of tiny, fast, electrically charged particles

The solar wind can interact with Earth’s magnetic field to create powerful electric currents that cause        near the poles

• auroras 
• nuclear fusion 
• sun flares
• sunspots

Which of the following best describes the Sun's corona?

• Cooler areas on the Sun
• Bright arch-like loops that erupt from the photosphere
• Intense explosions that release magnetic energy
• Outermost layer of the Sun's atmosphere that emits a halo of light during a solar eclipse
