Solar flare

The video explains how the sun affects its atmospheric layers by heating plasma to extreme temperatures, leading to explosive events that occur over a few minutes. These events release charged particles that travel to Earth's atmosphere, causing aurorae a few days later.

What is the effect of the sun on its atmosphere?

• It causes the atmosphere to shrink.

• It cools the atmosphere.

• It heats the plasma to millions of degrees.

• It makes the atmosphere transparent.

What happens to the plasma in the sun's atmosphere?

• It freezes

• It evaporates

• It solidifies

• It heats to tens of millions of degrees

How quickly do solar events occur?

• Over several days

• In a few hours

• Within a few minutes

• Over a month

What causes aurorae on Earth?

• Charged particles from solar explosions

• Volcanic eruptions

• Earth's magnetic field

• Sunlight reflecting off the moon

When do charged particles from solar explosions reach Earth's atmosphere?

• Immediately

• Within a year

• A few days later

• After a month
