Lesson 6.7 The Sun

Question 5 • 26/27 EARTH & SPACE SCIENCE A

Carrie is making a presentation on solar winds. Her notes of the steps that must occur for solar winds to form are below.1. The stream of electrically charged particles collide with gas atoms, causing the latter to give off light.2. The electrically charged particles flow outward in all directions as far as Saturn.3. The stream of electrically charged particles flows outward from the corona.4. The particles of the solar wind flow along lines of the magnetic field.Which shows the correct sequence in the formation of solar winds?

Answer
A
1, 2, 3, 4
B
2, 3, 4, 1
C
3, 2, 4, 1
D
4, 2, 1, 3

Explanation

The solar wind begins when electrically charged particles flow outward from the Sun’s corona (step 3). They spread outward through space as far as Saturn (step 2), and the particles travel along magnetic-field lines (step 4). When they collide with gas atoms, those atoms give off light (step 1), so the sequence is 3, 2, 4, 1: choice C.
