Solar Phenomena and Experiments Quiz

What is the size comparison between sunspots and Earth?

• Sunspots are 5 to 10 times the size of Earth.

• Sunspots are about the same size as Earth.

• Sunspots are 100 times the size of Earth.

• Sunspots are smaller than Earth.

What is the main challenge in predicting solar storms?

• The distance of the sun from Earth.

• The speed of the sun's rotation.

• The size of the sunspots.

• The unpredictability of which sunspots will cause storms.

What is the primary focus of Professor Carrie Forest's research?

• Calculating the age of the universe.

• Studying the surface of the Earth.

• Understanding the dynamics inside stars.

• Measuring the distance to the sun.

What dangerous element is used in the experiment to mimic star dynamics?

• Liquid hydrogen

• Liquid helium

• Liquid sodium

• Liquid nitrogen

How are magnetic fields amplified in the experiment?

• By adding more liquid sodium.

• By creating flows that spin in opposite directions.

• By increasing the temperature.

• By using larger propellers.

What happens to the magnetic field as the speed of the experiment increases?

• It decreases.

• It takes a massive leap.

• It disappears.

• It remains constant.

What does the experiment reveal about the surface of the Sun?

• It is calm and stable.

• It is noisy and chaotic.

• It is cold and dark.

• It is smooth and uniform.

What is the potential threat of space weather?

• It can disrupt communication systems.

• It can cool down the Earth's atmosphere.

• It can change the Earth's orbit.

• It can cause earthquakes.

What is one way that magnetic energy finds its way to the Sun's surface?

• Through solar eclipses.

• Through solar flares.

• Through sunspots.

• Through solar winds.

Why is space weather considered a 'scary thing'?

• Because it is unpredictable and powerful.

• Because it is always visible.

• Because it is harmless.

• Because it is easy to control.
