Chuckran/Hill Solar Wind Quiz Based on what you have learned so far, answer these multiple choice and true/false questions on the solar wind. Image courtesy of NASA

Chuckran/Hill Wind on earth is moving air, made mostly of … A) nitrogen and oxygen B) hydrogen and helium C) water and methane D) pollen and pixie dust

Chuckran/Hill The highest wind speed ever recorded on Earth was A) 123 mph B) 231 mph C) 321 mph D) 3210 mph

Chuckran/Hill The solar wind is composed of… A) hydrogen and helium molecules B) protons, electrons and ions C) fire and flames D) nitrogen and oxygen

Chuckran/Hill How fast IS that? The solar wind averages 300 km/sec. How fast is that in miles per hour? A) 55 mph B) 300 mph C) 22,000 mph D) 670,000 mph

Chuckran/Hill True or False? The density of the solar wind is usually around 1 proton per cm 3. That is significantly lower than the density of air.

7 Chuckran/Hill 2007 True or False? Even traveling at 300 km/sec, the solar wind would NOT knock you over.

Chuckran/Hill The solar wind has the greatest effect on Earth’s ….. A) magnetic field B) core C) oceans D) winds

Chuckran/Hill The solar wind can cause…. A) Auroras B) Satellite disruptions C) Power failures D) Radiation expose to astronauts E) All of the above

Chuckran/Hill What does the solar wind carry with it? A) Sunspots B) Heat C) Light D) Sun’s magnetic field
