The rapid drift of the indian tectonic plate
Webb印度板塊（英語：Indian Plate）為次級的大陸板塊，屬於印度-澳洲板塊的一部分，包括印度次大陸和印度洋。 印度板塊形成於九千萬年以前的白堊紀，自非洲東部的馬達加斯加分離，每年向北漂移15厘米，大約在五千到五千五百萬年以前的新生代的始新世時期和亞洲撞合，這一時期，印度板塊移動了約2,000-3,000公里距離，比已知的任何板塊移動的速度要 … WebbThe motion of tectonic plates colliding, separating, or just sliding along next to one another is responsible for a range of tectonic activities including earthquakes, volcanoes, and the formation of mountains.

WebbPlate reconstructions based on palaeomagnetic data suggest that the Indian plate attained a very high speed (18–20 cm yr-1 during the late Cretaceous period) subsequent to its breakup from Gondwanaland, and then slowed to ∼5 cm yr-1 after the continental collision with Asia ∼50 Myr ago1,2.

WebbThe Indian Plate, along with modern-day Africa, Australia, Antarctica, and South America, constituted part of the supercontinent Gondwana until around 140 million years ago. As these continents drifted apart at various speeds, Gondwana disintegrated, resulting in the opening of the Indian Ocean. Webb19 mars 2024 · The rapid drift of the Indian tectonic plate[J].

Webb14 mars 2024 · In the 1960s, the theory of plate tectonics revolutionized the Earth sciences by explaining how geologic plates drift apart and into each other, causing mountain building, volcanic eruptions and earthquakes. But researchers understand little about why plates move the way they do.

WebbBy 1965, investigations led to the proposal that Earth's surface was broken into seven large plates and several smaller plates. It was further suggested that Line these plates are rigid, and that their boundaries are Line 5 marked by earthquakes and Volcanic activity.
