Solar Storms

The video discusses solar activity, focusing on phenomena like coronal mass ejections and solar flares. It explains how these events, driven by the sun's magnetic fields, can impact Earth by affecting technology and posing risks to astronauts. The video also highlights the challenges in predicting solar storms, despite scientific efforts.

What spacecraft was used to capture footage of solar activity?

• Chandra X-ray Observatory

• Hubble Space Telescope

• Voyager 1

• STEREO A

What happens to the sun's magnetic poles approximately every 11 years?

• They reverse

• They remain unchanged

• They become stronger

• They disappear

What is a coronal mass ejection?

• A solar eclipse

• A sunspot formation

• A large release of plasma from the sun's corona

• A type of solar flare

How can solar storms affect Earth?

• They can change the Earth's orbit

• They can disrupt power grids and communications

• They can increase global temperatures

• They can cause earthquakes

What was unusual about the solar activity prediction for 2010?

• It was expected to be a quiet year

• It was the year of the largest solar storm ever recorded

• It was predicted to be a major solar flare year but wasn't

• It was the first year without any solar activity
