Question

question 2 (5 points) listen which statement about thunderstorms is correct? a) thunder can occur without lightning. b) thunder is heard before lightning is seen. c) lightning is seen before thunder is heard. d) lightning and thunder are not related to thunderstorms. question 3 (5 points) listen

Explanation:

Question 2

• Option A: Thunder is caused by lightning (the rapid heating and expansion of air due to lightning), so thunder cannot occur without lightning. Eliminate A.
• Option B: Light travels faster than sound. So lightning (light) is seen before thunder (sound) is heard. Eliminate B.
• Option C: Since light (from lightning) travels at a much higher speed (\(c = 3\times10^{8}\,m/s\)) than sound (from thunder, \(v\approx 343\,m/s\) in air), we see lightning before we hear thunder. This is correct.
• Option D: Lightning and thunder are both key components of thunderstorms (lightning causes thunder, and both are produced during thunderstorm processes). Eliminate D.

Answer:

C) Lightning is seen before thunder is heard.
