Question

which is true about thunderstorms?
a they can not occur in the winter.
b all produce tornadoes.
c 1/2 produce tornadoes.
d all thunderstorms produce lightning.

Explanation:

To determine the correct answer, we analyze each option:

• Option A: Thunderstorms can occur in winter (e.g., in some regions with winter thunderstorms), so A is false.
• Option B: Not all thunderstorms produce tornadoes; tornadoes are a less common, more intense outcome, so B is false.
• Option C: The "1/2 produce tornadoes" claim is incorrect as most thunderstorms do not produce tornadoes.
• Option D: By definition, a thunderstorm is a storm with thunder and lightning, so all thunderstorms produce lightning. This is true.

Answer:

D. All thunderstorms produce lightning.
