What Are The 3 Compositional Layer Of The Earth? The earth is made up of three different layers: the crust, the mantle and the core. This is the outside layer of the earth and is made of solid rock, mostly basalt and granite. There are two types of crust; oceanic and continental. What are the
What Is Another Name For A Spreading Center? The first sort of plate boundary is called a divergent boundary, or spreading center. At these boundaries, two plates move away from one another. What happens at a spreading center? Spreading centers occur where two plates are moving away from each other, and deep cracks are opened
Is The Continental Crust Solid Or Liquid? The crust is made of solid rocks and minerals. Beneath the crust is the mantle, which is also mostly solid rocks and minerals, but punctuated by malleable areas of semi-solid magma. Is the oceanic crust solid liquid or plastic? The crust is an outer solid layer where life
Where Is A Oceanic To Oceanic Convergent Boundary? Examples of ocean-ocean convergent zones are subduction of the Pacific Plate south of Alaska (creating the Aleutian Islands) and under the Philippine Plate, where it creates the Marianas Trench, the deepest part of the ocean. What is oceanic to oceanic convergence? Oceanic – oceanic convergence In collisions
Where Is Africa Splitting Apart? The East African Rift system made up the western and eastern continental rifts, and stretches from the Afar region of Ethiopia down to Mozambique. It is an active continental rift that began millions of years ago, splitting at 7mm annually. Which part of Africa is getting separated? But the Somali
Which Process Is Involved When The Oceanic Crust Plunges Down Into The Mantle? This process, called subduction, occurs at the oceanic trenches (figure 6). The entire region is known as a subduction zone. Subduction zones have a lot of intense earthquakes and volcanic eruptions. The subducting plate causes melting in the mantle. What is it
What Are 4 Pieces Of Evidence For Continental Drift? The four pieces of evidence for the continental drift include continents fitting together like a puzzle, scattering ancient fossils, rocks, mountain ranges, and the old climatic zones’ locations. What are 6 pieces of evidence that support continental drift? Fossils. Continents fit like Puzzle Pieces. Matching fossils
Can A Plate Have Both Oceanic And Continental Crust? Tectonic plates can transport both continental crust and oceanic crust, or they may be made of only one kind of crust. Oceanic crust is denser than continental crust. At a subduction zone, the oceanic crust usually sinks into the mantle beneath lighter continental crust. Which tectonic
At What Type Of Plate Boundary Is Oceanic Crust Created? Oceanic crust is created at divergent boundaries, such as the mid-ocean ridge. Oceanic crust is destroyed at convergent boundaries where subduction results in a trench, such as the Mariana Trench or Cayman Trough.] At which type of boundary is new oceanic crust created quizlet? The
Which Term Is Described As A Flat Expanse Of The Ocean Floor? Which term is described as a flat expanse of ocean floor? Abyssal Plains. Which feature of the ocean floor is the continental shelf? The continental shelf is an area of relatively shallow water, usually less than a few hundred feet deep, that surrounds
