Solution
The correct option is D all of these
Our entire Earth’s land is divided into big pieces of landmass called continents. At present, seven continents are there. They are Asia, Africa, North America, South America, Antarctica, Europe, and Australia. Most of them are separated from each other by the sea. It is believed that the formation of Earth took place around 4.5 billion years ago (bya).
About 300 million years ago, Earth did not have seven continents, but instead one massive supercontinent called Pangaea, which was surrounded by a single ocean called Panthalassa was present.
About 200 million years ago, the forces that helped to form Pangaea started to break it apart. Therefore, the Pangaea started to become pieces of land. These pieces of land began to move apart. This was the beginning of formation of all the different continents that we have today. This moving apart of land masses and formation of different continents is called continental drift.
While the continents were breaking or moving apart, certain ecological niches were getting destroyed. This leads to the death of a huge number of plants and animals, i.e., mass extinction takes place. Once they die and get fossilised, their distribution gets altered depending on the location where the piece of land gets drifted due to continental drift.
Geographical upheavals imply upward displacement or changes happening in the Earth’s crust. Continental drift affects geographical upheavals as well as the type of climate, plants and animals inhabiting in a geographical area.
Hence, continental drift can result in mass extinctions, distribution of fossils on Earth and geographical upheavals.
