Question

which piece of evidence suggests that africa and south america formed gondwana 200 million years ago? coal fields a shared ocean folded mountains land formations created by glaciers

Explanation:

The question is about geological evidence for the formation of Gondwana (including Africa and South America) 200 million years ago. Land formations created by glaciers (glacial landforms) can be used to show past continental connections. Glacial striations and tillite deposits in matching patterns across Africa and South America support the idea they were once joined. Coal fields, a shared ocean, or folded mountains don't directly relate to glacial evidence of continental drift here. So the correct option is land formations created by glaciers.

Answer:

land formations created by glaciers
