The difference in weight causes the ocean plate to subduct beneath the continental plate. The ocean plate melts in the upper mantle and it is recycled into new rocks. This clarifies what is plate tectonics theory of convergent boundaries.What is a transform boundary?
The third type of plate boundary is called a transform boundary. Here, two plates slide past one another. As this happens, rocks and sediment located on the boundary are crushed between the plates, which results in an undersea canyon or a linear fault valley. As with the other two types o...
I'm doing a project on plate tectonics. What was the type of plate boundary that India and Africa had while joined with Pangaea? I know this isn't part of this topic, but please, I'm terribly desperate! Byanon150948— On Feb 09, 2011 ...
This map shows the seafloor and deformation below it at a fracture in the Wharton Basin in the Indian Ocean. This fracture likely formed when the ocean crust was formed, but now it is being turned into a new plate boundary. The depressions are indicative of a strike-slip fault, which is ...
According to plate tectonics, the Earth's crust is comprised of over a dozen rigid slabs, or plates. As these plates move over the Earth's fluid mantle, they interact with each other, forming plate boundaries or zones. Areas where plates are colliding fo
The Aleutian Trench, which has formed along the convergent boundary and has been produced by the subduction of the oceanic plate, extends for 2,000 miles. At its widest point, the trench is 50 to 100 miles across. Even more impressive is the tremendous depth of the Aleutian Trench, which ...
But some volcanoes occur not at the edges, but in the middle of a continental or oceanic plate. The Hawaiian Islands, for example, are thousands of kilometers away from any plate boundary, and yet you have vast amounts of magma, molten rock or lava, flowing up through the earth's crust...
What Are Challenges to Quantum Memory? What is the Quantum Critical Point? What Are the Quantum Mechanics of Photosynthesis? What Are Some Tests for Quantum Gravity and the Theory of Everything?
things such as volcanoes and earthquakes are more common because the Earth is moving, leaving openings formagmato rise up and because the movement between the plates generates friction. A lot of the boundary areas are near the shoreline of the ocean, which is one reason why those areas are ...
