Question

How can seafloor spreading be detected?

Answer 1

Hint: Seafloor spreading is a geologic cycle wherein tectonic plates, enormous sections of Earth's lithosphere separates from one another. It happens at dissimilar plate boundaries.

Complete answer: Seafloor spreading happens when magma emits from the lift valley that runs the length of the edge. At the point when the magma gushes and solidifies, the seafloor is driven away on one or the other side of the edge. The solidified magma frames new seafloor. Researchers brought these perceptions in the mid-1960s to make the ocean bottom spreading theory. For example, the Mid-Atlantic Ridge isolates the North American plate from the Eurasian Plate and the South American plate from the African Plate.

Seafloor spreading is the component for Wegener's drifting continents. Alfred Wegener, a meteorologist and geophysicist in 1912 put forward the theory of how continents shift their position, also known as the continental drift theory. Seafloor spreading is only one part of plate tectonics while subduction is another. Subduction happens where tectonic plates collide with one another as opposed to spreading separated. Subduction destroys old crust whereas seafloor creates new crusts.

Note: Seafloor bottom spreading is not reliable at all mid-sea ridges. Gradually spreading edges are the sites of tall, restricted submerged cliffs and mountains. Quickly spreading ridges have substantially more delicate inclines.
