What elements primarily make up our Sun?

Gaseous helium (He) and hydrogen (H)

What is the difference between a solar flare and a coronal mass ejection (CME)?

Solar flares mainly emit radiation. CMEs emit both matter AND radiation.

Our atmosphere protects us from much of the Sun's most harmful radiation. How?

Air absorbs lots of the most harmful radiation

Which statement best explains how sunspots move across the Sun's surface?

The sunspots show us how fast the Sun spins (rotates).

How does Earth protect us from much of the Sun's most harmful radiation?

Earth's magnetic field deflects energetic particles to the poles

What is the solar wind made of?

Magnetic fields and charged particles (plasma)

This is a general "grab bag" of questions to test your knowledge of heliophysics and the solar activity that we call space weather. NOAA and NASA work closely together to forecast and warn about the impacts of space weather.

Answers

1
What elements primarily make up our Sun?
Molten iron (Fe) and tungsten (W)
Gaseous helium (He) and hydrogen (H)
A secret blend of 11 plasmas and types of gasoline
Solid sodium (Na) and chlorine (Cl)
2
What is the difference between a solar flare and a coronal mass ejection (CME)?
Solar flares mainly emit radiation. CMEs emit both matter AND radiation.
CMEs mainly emit radiation. Solar flares emit both matter AND radiation.
Solar flares come from the core of the sun while CMEs come from the mantle.
Solar flares can be seen from space but CMEs cannot.
3
How long does it take light to travel the 150 million kilometers (93 million miles) from the Sun to Earth?
About 8 months
About 8 seconds
About 8 minutes
About 8 business days (excluding weekends)
4
Our atmosphere protects us from much of the Sun's most harmful radiation. How?
Air absorbs lots of the most harmful radiation
Cold arctic air freezes radiation in place
Lightning intercepts ionic particles
Harmful radiation turns into glorious, colorful sunsets
5
Which statement best explains how sunspots move across the Sun's surface?
It's an optical illusion; nothing is happening on the Sun's surface.
The sunspots are shadows cast by nearby planets like Mercury.
The sunspots are bouncing around like hot water on a pan.
The sunspots show us how fast the Sun spins (rotates).
6
How does Earth protect us from much of the Sun's most harmful radiation?
Solar radiation cannot get through Earth's stainless steel armor
Earth's magnetic field deflects energetic particles to the poles
Radio waves flow from north and south poles and deflect harmful radiation
Magnetic asteroids suck up harmful radiation
7
How long does it take solar wind to travel the 150 million kilometers (93 million miles) from the Sun to Earth?
About 2 to 4 days
About 2 to 4 months
About 2 to 4 hours
About 2 to 4 minutes
8
What is the solar wind made of?
Charged particles (plasma) and magnetic monopoles
Solar surfers and sunspots
Hot air
Magnetic fields and charged particles (plasma)
