South American Plate

The South American Plate is a continental tectonic plate which includes the continent of South America and also a sizeable region of the Atlantic Ocean seabed extending eastward to the Mid-Atlantic Ridge.

The easterly side is a divergent boundary with the African Plate forming the southern part of the Mid-Atlantic Ridge. The southerly side is a complex boundary with the Antarctic Plate and the Scotia Plate. The westerly side is a convergent boundary with the subducting Nazca Plate. The northerly side is a boundary with the Caribbean Plate and the oceanic crust of the North American Plate. At the Chile Triple Junction in Taitato-Tres Montes Peninsula, an oceanic ridge — the Chile Rise — is subducting under the South American plate.

The South American Plate is in motion, moving westward away from the Mid-Atlantic Ridge. The eastward-moving and more dense Nazca Plate is subducting under the western edge of the South American Plate along the Pacific coast of the continent at a rate of 77 mm per year. This collision of plates is responsible for lifting the massive Andes Mountains and causing the volcanoes which are strewn throughout them.

Famous quotes containing the words south american, south, american and/or plate:

    Indeed, I believe that in the future, when we shall have seized again, as we will seize if we are true to ourselves, our own fair part of commerce upon the sea, and when we shall have again our appropriate share of South American trade, that these railroads from St. Louis, touching deep harbors on the gulf, and communicating there with lines of steamships, shall touch the ports of South America and bring their tribute to you.
    Benjamin Harrison (1833–1901)

    ...I always said if I lived to get grown and had a chance, I was going to try to get something for my mother and I was going to do something for the black man of the South if it would cost my life; I was determined to see that things were changed.
    Fannie Lou Hamer (1917–1977)

    The American who has been confined, in his own country, to the sight of buildings designed after foreign models, is surprised on entering York Minster or St. Peter’s at Rome, by the feeling that these structures are imitations also,—faint copies of an invisible archetype.
    Ralph Waldo Emerson (1803–1882)

    Say “Yessum” to the ladies, an’ “Yessur” to the men,
    And when they’s company, don’t pass yer plate for pie again;
    But, thinkin’ of the things yer’d like to see upon that tree,
    Jes ‘fore Christmas be as good as yer kin be!
    Eugene Field (1850–1895)
