Question

which explanation provides support for continental drift theory? dinosaurs lived on many continents. coal fields match up across continents. tropical plant fossils were found in warm areas. mountains formed where earth cooled and shrank.

Explanation:

The continental drift theory states that continents were once joined as a single landmass and have moved apart. Matching coal fields across separate continents indicates these landmasses were once connected, as coal forms in specific ancient environmental conditions that would only be continuous if continents were united. The other options do not support this: dinosaurs living on multiple continents does not require continental connection, tropical fossils in warm areas is expected, and the shrinking Earth mountain formation is an outdated, unrelated idea.

Answer:

Coal fields match up across continents.
