A part of the eurasian plate is named.

Tectonic plates near me.

Plates which do not longer exist are not listed. Major tectonic plates by size pacific plate 103 300 000 sq km the pacific plate is estimated to be 103 300 000 square kilometers in size. According to the theory earth has a rigid outer layer known as the lithosphere which is typically about 100 km 60 miles thick and overlies a plastic moldable partially molten layer called the asthenosphere the lithosphere is broken up into seven very large continental and ocean sized plates six or seven medium sized regional. The concept of plate tectonics was formulated in the 1960s.

This is a list of tectonic plates on earth s surface. Convergent colliding boundaries are shown as a black line with teeth divergent spreading boundaries as solid red lines and transform sliding alongside boundaries as solid black lines. It is the longest. Here are two plate tectonics maps which show more detail than the maps above.

Shaded relief map of the u s. The list of tectonic plates consists proved and proposed tectonic plates of the earth. As they move only inches every year and depending on the direction of that movement they collide forming deep ocean trenches mountains volcanoes and generating earthquakes. Many of the mountains and some of the valleys in southern california were formed by the san andreas fault system the tectonic boundary between the pacific and north american tectonic plates which runs to the east of san diego county from the gulf of california up through the salton sea and into the los angeles region.

Oceanic crust also called sima from silicon and magnesium and continental crust sial from silicon and aluminium. The earth s plates jostle about in fits and starts that are punctuated with earthquakes and volcanic eruptions. There are a total of seven major tectonic plates which cover nearly 95 of the earth s surface. A map of global tectonic and volcanic activity over the last one million years showing.

The crust of our planet is cracked into seven large and many other smaller slabs of rock called plates averaging about 50 miles thick. There are a few handfuls of major plates and dozens. Highlighting different tectonic settings. Geological survey map of tectonic plates show 21 of the major plates as well as their movements and boundaries.

Other plates the southern tip of the juan de fuca plate is often considered a separate plate called gorda plate. Letter codes are abbreviations for parks on tectonic settings pages and the tectonic settings master list on the plate tectonics our national parks page. The northern tip of the juan de fuca plate is sometimes considered to be the separate explorer plate. Found underneath the pacific ocean it is the largest of all tectonic plates.
