What tectonic plate are the Sierra Nevada mountains on?
The Sierra Nevada Mountains are near the western edge of the North American plate.
Where tectonic plates collide, the intervening crust can be folded or pushed up to form mountains. In the case of the Sierra Nevada, an ancient collision forced magma from an oceanic plate beneath the western part of North America. After millions of years, erosion and glaciation has exposed these underground rocks, or plutons, which form the bases of the mountains of the range.
The Sierra Nevada Mountains formed by a thinning of the North American Plate which then cracked as a result of upward pressure. Huge blocks of rock containing huge chunks of granite welled up at this crack and tilted up along it. The upward tilting edges became the Sierra Nevada ridge line less than 4mya. Erosion exposed granite at places such as Yosemite's Half Dome. A 2004 study of the Southern Sierras concluded that a massive…
What would be the best explanation for the existence of the andes mountains along the west coast of south america?
The Andes Mountains formed because two tectonic plates (a tectonic plate is a piece of the Earth's crust), the Nazca Plate and the Antarctic Plate, pushed into the western edge of South America. This compressed the western edge of the South American plate, and folded it, creating the Andes Mountains. A few of the mountains were formed by volcanic activity. which is also the result of the collision between this plates.
What is the name of the tectonic process that has created many of the mountains in Middle and South America?
When tectonic plates converge together at the bottom of the ocean the oceanic plate goes under the continental plate because the oceanic plate weighs more and then the oceanic plate pushes up the continental plate which forms mountains and sometimes the tectonic plates let magma through which goes up through the continental plate and then opens a hole at the top of the mountains called a vent which is where the steam, volcanic ash, debris…
Every place on earth is on a tectonic plate as the earth crust consists of tectonic plates. And every tectonic plate is constantly in motion (as they float on magma, beneath the crust). Places which suffer most of earthquakes are in between two tectonic plates. an example of such a place is the City of Los Angeles in California. Mid Oceanic ridges and rifts and mountains are also results of plate tectonics.
