Has the pacific plate sped up or slowed down
WebThe Pacific Plate subducts beneath Tonga and appears in Figure 9.1.8 as a 100 kilometre thick slab of cold (blue-coloured) oceanic crust that has pushed down into the surrounding hot mantle. The cold rock is more rigid than the surrounding hot mantle rock, so it is characterized by slightly faster seismic velocities. WebHeiko Pälike, ...

But the... WebThe rate of spreading along the Mid-Atlantic Ridge averages about 2.5 centimeters per year (cm/yr), or 25 km in a million years. This rate may seem slow by human standards, but because this process has been going on for millions of years, it has resulted in plate movement of thousands of kilometers.

They are dramatically amplified C. They slow down so the seismic velocity decreases D. They cannot be transmitted so the velocity goes to zero. The Pacific Plate is an oceanic tectonic plate that lies beneath the Pacific Ocean. At 103 million km (40 million sq mi), it is the largest tectonic plate. The plate first came into existence 190 million years ago, at the triple junction between the Farallon, Phoenix, and Izanagi Plates. The Pacific Plate subsequently grew to where it underlies most of the Pacific Ocean basin. Thi…
