Look at maps of volcanoes, earthquakes and island chains like the Philippines and Japan, and you can see the rough outlines of what are called tectonic plates – the plates which make up the earth’s crust and mantle. The most dramatic of these is the Pacific ‘ring of fire’ where ...
Tectonic Plates: Large pieces of the Earth's crust that move and interact.构造板块Atmospheric Circulation: The movement of air within the Earth's atmosphere.大气环流Climate Change: Long-term shifts in global or regional climate patterns.气候变化Greenhouse Effect: The trapping of heat in Earth’s...
Essentially, this job is related to the core subjects related to ocean engineering. The fundamental task of these professionals is to handle the variety of equipment along with the construction of ocean-related structures. They will also be working on the research background to study and review s...

Local Tibetans have named Everest Chomolungma, which translates to “Goddess of the World or of the Valley.” Sanskrit calls it “Peak of Heaven”.” It was officially labeled the highest peak in 1852. Amazingly, Everest has not stopped growing, thanks to tectonic plates it reaches a little ...
It lies across the edges of 4 tectonic plates. Most earthquakes are born in such places. When two tectonic plates push together, the earthquake sends enormous amounts of energy up through the ocean. A series of waves expands in all directions. In deep water. these waves travel fast-up to...
Until 1970, scientists believed the Philippine Trench, which stretches southwest from Luzon to the island of Halmahera in Indonesia, was the deepest point on the planet. It's the result of a collision between the Eurasian plate, which is one of the Earths' seven major tectonic plates, and th...
plates kept moving apart and brought the 7 continents of the world into the present arrangement. Concerning tectonic plates, these are huge slabs of the earth’s crust floating on the hot melted rock below. A single tectonic plate can carry the whole continent along with a piece of an ocean...
Most volcanoes appear along the sides of the huge plates (known astectonic plates) that make up the surface of the world – either where the plates are moving apart, or where they are moving together and one plate is forced under another. ...
Eighty-three million years ago, south of Australia, seafloor spreading created a mid-ocean ridge of rising mantle. Later the ridge was compressed by colliding tectonic plates leading to uplift raising part of the ridge above the ocean surface creating Macquarie island. Here, remarkably, geologists ...
