Question

question 1 of 10
which would most likely trigger a climate change that could lead to a mass
extinction?

a. formation of a supercontinent

b. glacier movement

c. earthquakes

d. volcanic outgassing

Explanation:

To determine the answer, we analyze each option:

• Option A: Formation of a supercontinent can cause significant climate changes (e.g., changes in ocean currents, wind patterns, and temperature distributions) over long periods, which can disrupt ecosystems and potentially lead to mass extinctions.
• Option B: Glacier movement primarily affects local or regional areas, like shaping landscapes, and is less likely to trigger global climate change leading to mass extinction.
• Option C: Earthquakes are mostly local geological events, affecting small areas, and do not directly cause global climate change for mass extinction.
• Option D: Volcanic outgassing, while it can affect climate, large - scale supercontinent formation has a more profound and long - term impact on global climate systems related to mass extinction events in geological history.

Answer:

A. Formation of a supercontinent
