Question

what major climate system influenced ecosystems along the eastern margins of pangaea? powerful monsoons with alternating wet - dry cycles, trade winds, permanent drought conditions, polar vortex winds multiple choice 2 points

Explanation:

Pangaea's eastern margins were influenced by powerful monsoons with alternating wet - dry cycles that affected local ecosystems. Polar vortex winds mainly affect polar regions, trade winds have a different global distribution pattern and are not the main climate factor for Pangaea's eastern margins, and permanent drought conditions do not accurately describe the climate there.

Answer:

Powerful monsoons with alternating wet - dry cycles
