It causes the seafloor and outermost crust (the lithosphere) to bend and form a steep, V-shaped depression.
Answer:
The crust broke up because of the convection currents, formed tectonic plates, and is slowly pushed on the surface until it collides with another plate and subducts.
Explanation:
This image gives us the basics of how the plate tectonics theory works. The material in the upper mantle is cooler and denser than the material in the lower mantle, so it drops down and it pushes the hotter and less dense material up. This creates a circular motion in the mantle, and this motion creates enormous pressure on the crust above it and breaks it up.
As the crust is broken up, magma is rising constantly for millions of years, so the new magma pushes the old solidified one further away. This also pushes two pieces of crust away from each other. As the crusts move away, they eventually collide with another plate, and either gradually merge with it, or a subduction zone is created. In the latter, the crust moves below another crust and into the mantle, where it gets melted and recycled.
Answer:
वायुमण्डल में एक निश्चित मात्रा में पाई जाने वाली गैसों- नाइट्रोजन, ऑक्सीजन तथा कार्बन-डाई-ऑक्साइड की मात्रा क्रमशः 78 प्रतिशत, 21 प्रतिशत और 0.3 प्रतिशत है और शेष असक्रिय गैसें पाई जाती हैं।
Answer:
Densidad.
Explanation:
The greater the density of an oceanic lithosphere plate, the greater the weight of that plate. This will affect the degree of subduction of that card. The higher the density, the greater the degree of subduction and the ability of the plate to descend, forcing the creation of prominent and well-defined trenches on the ocean floor.
The density of the plaque increases as the age of the plaque increases, so we can consider age, another factor in the formation of these trenches.
