Draw a Convergent Plate Boundary. Draw a Divergent Plate Boundary. Draw a Transform Boundary. Name 2 Types of Plates and what material are they mostly made of? What is the theory of plate tectonics? Plate Boundaries Divergent Boundaries Describe what is rifting and where rifting will be found....
What is Plate Tectonics The Earth’s crust and upper mantle are broken into sections called plates Plates move around on top of the mantle like rafts What is the Lithosphere? The crust and part of the upper mantle = lithosphere 100 km thick Less dense than the material below it so it “...

plate tectonics, Theory that the Earth’s lithosphere (the crust and upper portion of the mantle) is divided into about 12 large plates and several small ones that float on and travel independently over the asthenosphere.
板块的岩石密度低于熔融岩石,因此构造板块,包括承载大陆的板块,漂浮在地幔上。构造板块对大陆漂移的解释的一个重要部分是,地幔中的熔融岩石被迫通过两个板块交汇的大洋中山脊的海底。这种熔融物质为山脊两侧的板块添加了新的海洋地壳。海底从洋中脊向两个方向伸展,脊两侧的构造板块随着新的海洋地壳的增加而相互分离。与...
Plate tectonics is a theory in geology. This theory primarily explains the proof of the large movements of the earth’s lithosphere. The lithosphere is the outermost layer of solid rock of a planet. The lithosphere consists of the uppermost mantle and the crust. These two are joined together ...
