Understanding Solar Storms and Their Impact

What role does the Sun play in supporting life on Earth?

• It controls the Earth's gravity.

• It supplies energy that fuels life.

• It creates the Earth's atmosphere.

• It provides oxygen for breathing.

What are solar storms primarily caused by?

• The Moon's gravitational influence.

• The Sun's magnetic activity.

• The Sun's gravitational pull.

• The Earth's magnetic field.

What is a coronal mass ejection (CME)?

• A decrease in the Sun's magnetic activity.

• A sudden increase in the Sun's temperature.

• A massive eruption of plasma and magnetic fields from the Sun.

• A type of solar flare.

Which observatory provides a 3D view of solar activity?

• Solar Terrestrial Relations Observatory

• Chandra X-ray Observatory

• James Webb Space Telescope

• Hubble Space Telescope

How do scientists predict the impact of CMEs on Earth?

• By measuring the Sun's temperature.

• By analyzing the Sun's magnetic field changes.

• By observing the Earth's atmosphere.

• By tracking the Moon's orbit.

What recent change in solar activity has been observed?

• A reduction in the Sun's magnetic field.

• A decrease in the frequency of CMEs.

• A significant increase in sunspot count.

• A decrease in solar flares.

What can a geomagnetic storm trigger when it hits Earth's atmosphere?

• An increase in Earth's temperature.

• A reduction in solar activity.

• A decrease in Earth's gravity.

• A geomagnetic storm.

What is a potential consequence of geomagnetic storms on power grids?

• Increased power efficiency.

• Fluctuations and outages.

• Improved satellite communication.

• Enhanced radio signals.

How can geomagnetic storms affect satellites?

• By increasing their speed.

• By causing surface charging and potential malfunctions.

• By improving their communication capabilities.

• By reducing their operational lifespan.

What happens to auroras during intense geomagnetic storms?

• They become brighter and more vivid.

• They disappear completely.

• They change color to red.

• They become less visible.
