Which piece of evidence suggests that Africa and South America formed Gondwanaland 200 million years ago Brainly?
Answer: The existence of Gondwana was first hypothesized in the mid-1800s by Eduard Suess, a Viennese geologist who dubbed the theoretical continent “Gondwanaland.” Suess was tipped off by similar fern fossils found in South America, India and Africa (the same fossils would later be found in Antarctica).
What formed Gondwanaland 200 million years ago?
According to plate tectonic evidence, Gondwana was assembled by continental collisions in the Late Precambrian (about 1 billion to 542 million years ago). Gondwana then collided with North America, Europe, and Siberia to form the supercontinent of Pangea. The breakup of Gondwana occurred in stages.
What evidence is there that Gondwanaland once existed?
Plant evidence: Fossil evidence suggests that temperate rainforest was widespread in Australia, Antarctica, South America and New Zealand around 45 million years ago. Such fossils and the surviving species in Tasmania provide evidence of the ancient link to Gondwana.
Which coastlines most closely match each other and are therefore used as evidence?
The coastline of Africa and South America, India, Antarctica and Australia fit one another, Eurasia and North America also fit together. Among the choices given, the coastline most closely match each other and are therefore used as evidence to support Wegener’s theory is South America and Africa.
When were Earth’s landmasses first recognizable as the continents we know today?
Pangaea existed about 240 million years ago. By about 200 million years ago, this supercontinent began breaking up. Over millions of years, Pangaea separated into pieces that moved away from one another. These pieces slowly assumed their positions as the continent we recognize today.
What continents made up Gondwana?
Gondwana included most of the land masses in today’s southern hemisphere, including Antarctica, South America, Africa, Madagascar and Australasia, as well as the Arabian Peninsula and the Indian subcontinent, which have now moved entirely into the northern hemisphere.
What two major landmasses broke apart from Pangaea?
Pangaea begins to break up and splits into two major landmasses — Laurasia in the north, made up of North America and Eurasia, and Gondwana in the south, made up of the other continents.
Are Gondwana and Pangea the same?
Pangea, the most recent supercontinent, attained its condition of maximum packing at ~250 Ma. At this time, it consisted of a northern part, Laurasia, and a southern part, Gondwana. Gondwana contained the southern continents—South America, Africa, India, Madagascar, Australia, and Antarctica.
How many supercontinents were there before Pangaea?
You’ve probably heard of Pangaea, the enormous supercontinent that formed 300 million years ago and broke apart into the continents we know today. But did you know scientists believe that a total of seven supercontinents have formed over the course of Earth’s history?
