Plate tectonics – the slow movement of Earth’s continents around the world, and their interactions with one another – is a relatively new discovery, having not been widely accepted in the geological community since the mid-1960s. In addition to studying the seven large plates that make up the main continents on Earth, some scientists are studying the remnants of the vanishing plates that slipped under the edge of the continent and fell into the mantle. Now, a group studying northwestern North America has discovered what it believes to be the remains of a now-vanished plate that slid under the Pacific Northwest millions of years ago.

Geologists agree that the west coast of North America was shaped by a complex interaction of multiple plates. Two of the split panels now below this region of the US and Canada are the Farallon and Kula panels. The existence of a third plate – dubbed the Resurrection – has been assumed controversially, with some geologists arguing that it explains some of the features of the terrain (and terrain) in certain areas. Now that new evidence has emerged, it appears that the Ba’athists have won.

pyramid. Perhaps this name should not be used.

The “pro-resurrection” side of the debate appears to have won. After isolating the crowd that appeared to belong to Cola and Farallon, the team rose up Reports There are gaps in the reconstruction in the registry, which:

… correlate spatially with magma near the diffused NW Cordillera trench, even considering the possibility of translating the terrain. We attribute these gaps to thermal erosion associated with subduction of ridges and mid-ocean ridge patterns within the midpoints of this reconstruction gap. Our reconstructions show two ridge intersections with a trench bordering an additional “resurrection” plate along the NW Cordillera before 40 Ma. In this embodiment, the Yukon plate is a thermally corroded remains of the Resurrection board.

Now, I’m sure no one will Need Subtitles for that, but in case that helps, here’s a YouTube video showing how the process happened.

When “raised” back to Earth’s surface and rebuilt, the boundaries of this ancient tectonic plate of resurrection coincide perfectly with the ancient volcanic belts in Washington state and Alaska, providing a much-desirable association between the ancient Pacific Ocean and the geologist in North America says geologist Johnny Wu From the University of Houston.

There are a few interesting things about relationships that really have down-to-earth things. Mountain ranges form at plate boundaries, but they do not form at anything like constant velocity. One Explanation Because this rapid mountain formation is caused by pieces of falling plates that separate and push (very slowly) across the mantle, towards the core / mantle boundaries. Imagine throwing a bowling ball into a bathtub, then freezing the water the moment it reaches its maximum height, and you have an idea of ​​how these events occurred over the course of geological time.

Plate subduction is not the only thing reshaping the continents. After the last ice age, continents around the world began to rise as the ice layers melted. This is thought to have had a side effect that made local volcanic eruptions more likely because there was not much weight pressing on the continents. Static isothermal recoil still occurs to this day, although it is much slower than current rates of sea level rise and is not helpful in solving the problem due to the timelines involved.

Understanding where these hidden plates are located under our feet can aid our understanding of geological events at the surface, such as volcanoes. If volcanoes and earthquakes ever become predictable, it is likely thanks to a greater understanding of the deeper layers of Earth.
