";s:4:"text";s:3897:"Volcanoes on Mars appear to be dormant, but scientists aren't sure about that, either. However, UCLA scientist An Yin discovered evidence of plate… The largest canyon in the solar system, Valles Marineris, cuts a wide swath across Mars and extends more than 1,864 miles (3,000 kilometers) long and 372 miles (600 kilometers) across. It gives us a glimpse of how the early Earth may have looked and may help us understand how plate tectonics began on Earth," said An Yin, a UCLA professor of Earth and space sciences and the sole author of the new research. An Yin, a professor at UCLA, recently discovered that Mars has tectonic plates similar to those that we have on Earth. (Image credit: USGS) On Earth, plate tectonics build up mountains, set off tsunamis and form volcanoes. Tectonic plates interact with each other repeatedly, and the location where they do is called plate boundaries. Tectonic plates on Earth cause activity such as earthquakes and volcanoes as well as mountain-building as they move atop the asthenosphere and recycle geological materials. At least, until recently, Earth was the only planet known to have plate tectonics – it looks as if we can now add Mars to that list. Scientists can study how those waves bounce off layers deep underground, to help … Quakes on Earth happen many times a day, largely due to continental plates shifting as they float on the mantle below. This is thought to be due to the fact that Venus is hot and dry. Theorists expect the gradual cooling of Mars would have slowed tectonic … Alternate explanations for the banded structure may involve the fracturing and breakup of an ancient, uniformly magnetized crust due to volcanic activity or tectonic stresses from the rise and fall of neighboring terrain. Does Mars have plate tectonics? Mars is in a sense a rump version of Earth. However, both the ways this change has happened and the properties of the planet's lithosphere are both very different when compared to the Earth. Venus does have tectonic activity: faults, folds, volcanoes, mountains, and rift valleys.
An Yin, a professor at UCLA, recently discovered that Mars has tectonic plates similar to those that we have on Earth. Based on the nature of this interaction, plate boundaries can be classified into three types; divergent, convergent, and transform.
