NASA | Scientists Answer Top Space Weather Questions, Part II

The video explains solar events, their effects on Earth, and how we are protected from them. It covers the impact of space weather on technology and the importance of forecasting solar events. The solar activity cycle and its phases are discussed, highlighting the need for understanding solar maximum and its effects.

What determines whether a solar event will impact Earth?

• The distance of Earth from the sun

• The size of the solar event

• The location on the sun where it occurs

• The time of day on Earth

Which of the following is NOT a direct effect of space weather on Earth?

• Creation of dangerous radiation in space

• Disruption of communication systems

• Damage to satellites in orbit

• Direct harm to humans on Earth's surface

How long does it take for a solar flare to reach Earth?

• 8 minutes

• 20 to 30 minutes

• 1 to 4 days

• 1 week

What is the role of Earth's magnetosphere in protecting us from solar events?

• It amplifies solar flares

• It increases the speed of solar particles

• It deflects magnetic fields and energetic particles

• It absorbs all solar radiation

Why is it important to forecast solar events?

• To increase the sun's activity

• To protect technology and power grids

• To prevent solar flares from occurring

• To predict weather changes on Earth
