Matching coastlines and land formation created by glaciers are the two evidence that suggests that Africa, Antarctica, South America, India, and Australia formed Gondwana land 200 million years ago
Further Explanation:
Earth is being marked by almost five ice ages namely Huronian, late Paleozoic, Andean- Saharan, Cryogenian, and the latest one Quaternary Ice age. Well established earliest ice age rocks are called Huronian that is expected to be formed around 2 billion years ago during Proterozoic eon. Cryogenian has existed around 700 million years ago while the late Paleozoic age existed around 300 million years ago. Though the glacial period ended 8,000 years ago its effect is felt still today as its weight was so great that it led to the deformation of earth’s crust and mantle. During deglaciation sea level also rose and that resulted in the sudden shifting of the hydration system and coastline.
