time according astronomers. The planet has no signs of any type of weather such as clouds, rivers, and dust storms. The planet of Mercury closely resembles Earth's Moon. Mercury's surface shows intercrater plains, basins, smooth plains, craters, and tectonic features. Many of the smooth plains located on Mercury seem to be a result from flood volcanism. Some other features of Mercury geology are vents that are a result from magma-carved valleys and "hollows" that are believed to be from collapsed magma

Mercury is a very rocky planet, its surface is like the Earths moon. It lacks an atmosphere, but experiences extreme temperature anywhere between 90 to 700 Kelvin. It is geologically dead, however it does have a magnetic field which is generated inside the planets core, it magnetic field is only around one 500th of Earths. Mercury is dominated by its core, it has a radius of around 1800 Kilometres and has a less dense mantle which has a depth of 500-600 kilometres. 60 percent of Mercury's mass in

ejected during an eruption. Volcanoes are generally found where tectonic plates are diverging or converging. A mid-oceanic ridge, for example the Mid-Atlantic Ridge, has examples of volcanoes caused by divergent tectonic plates pulling apart; the Pacific Ring of Fire has examples of volcanoes caused by convergent tectonic plates coming together. By contrast, volcanoes are usually not created where two tectonic plates slide past one another. Volcanoes can also form where there is stretching

Antarctic, Eurasian, North American, South American, Pacific and Indo-Australian, as well as numerous smaller ones. While the plates that is moving the fastest are the Oceanic and Pacific plates, the Eurasian plate only moves about 21 mm per year and is therefore the slowest one. Generally, movement paces can differ between 0 and 100 mm in a year. These tectonic plates consist of oceanic lithosphere and rather thick continental lithosphere, and are surrounded by an individual crust

“The 1980 Mt Saint. Helens eruption will go down infamously as one of the Nation’s worst natural disasters to ever occur. ”This volcano killed 57 people in its 1980 eruption. The volcano is a stratovolcano, what is plate tectonics, how was it formed and relation with plate tectonics, finally it’s eruption in the 1980s. Also, how to prepare and be safe of a volcanic eruption. Mt St. Helens is a stratovolcano also known as a composite cone. A stratovolcano is the deadliest of all other volcanoes

Mercury: Surface Geology Mercury, the closest planet to the sun, is covered in craters, like, there are craters everywhere. There's also a lot of dust and boulders all over the place. In short, Mercury is like if you go fill an empty fish tank with rocks and sand, then dig some holes in there. Mercury has a magnetic field that's about 1/100th that of Earth's, it was discovered by Mariner 10, a Muggle space contraption. The field is generated from inside the planet, just like with Earth, as opposed

Characteristics Contributing on Canyon Evolution Kelly Neubauer FTS: Evolution October 14, 2014 The Grand Canyon is one of the largest canyons on Earth, spanning 277 miles and measuring up to 18 miles wide (National Park Service, 2014). This natural wonder is viewed by millions of tourists every year who come to see the remarkable views (National Park Service, 2014). While its beauty is impressive, so is the story behind the formation and evolution of the canyon. Every canyon in the world

features relate to plate tectonics. Bathymetry is the depth of water relative to sea level. Bathymetry measurements can show that the sea floor varies and is ever changing. They can show active and extinct volcanoes, mountain ranges, and canyons. Additionally, they can show deep sea trenches and subduction zones. Plate tectonics theory stated that the outermost layer of the earth was divided into lithospheric plates. The interaction of these plates are the process called plate tectonics. Bathymetry gives
