How do you make sea floor spreading?
Regional Specificssea-floor spreading — a hypothesis, proposed in the early 1960s, that new ocean floor is created where two plates move away from one another at mid-ocean ridges. subduction zone — a long, narrow zone where one lithospheric plate descends beneath another. How do you make a model of seafloor spreading? Quote from video:Hello my students

What is not a clastic sedimentary rock?
Regional SpecificsNon-clastic textures are found chiefly in rocks that have precipitated chemically from water (chemical sedimentary rocks), such as limestone, dolomite and chert. Other non-clastic sedimentary rocks include those formed by organisms (biochemical rocks), and those formed from organic material, such as coal. What are examples of non-clastic sedimentary rocks? Non-Clastic Sedimentary Rock Examples include rock

What do sedimentary rocks have lots of?
Regional SpecificsOrganic-rich sedimentary rocks have significant amounts of organic material, generally in excess of 3% total organic carbon. Common examples include coal, oil shale as well as source rocks for oil and natural gas. ), typically as chert, opal, chalcedony or other microcrystalline forms. What can only be found in sedimentary rocks? So most fossils are

Why is the continental crust important?
Regional SpecificsImportance. Because the surface of continental crust mainly lies above sea level, its existence allowed land life to evolve from marine life. Why is it important to know the two types of crust? There are two kinds of crust: continental crust, and ocean crust. Continental crust is thicker, and predominantly felsic in composition, meaning that

What determines the type of volcanic eruption?
Regional SpecificsThe style of eruption depends on a number of factors, including the magma chemistry and content, temperature, viscosity (how runny the magma is), volume and how much water and gas is in it, the presence of groundwater, and the plumbing of the volcano. What determines the type of volcanic eruption quizlet? The type of volcanic
