How do you think magma turns into extrusive igneous rock?
Regional SpecificsMagma that cools quickly forms one kind of igneous rock, and magma that cools slowly forms another kind. When magma rises from deep within the earth and explodes out of a volcano, it is called lava, and it cools quickly on the surface. Rock formed in this way is called extrusive igneous rock. How does

What forms at a convergent subduction boundary?
Regional SpecificsIf two tectonic plates collide, they form a convergent plate boundary. Usually, one of the converging plates will move beneath the other, a process known as subduction. Deep trenches are features often formed where tectonic plates are being subducted and earthquakes are common. What does a subduction boundary form? Oceanic crust is denser than continental

What are the 4 ways minerals are formed?
Regional SpecificsThe four main categories of mineral formation are: (1) igneous, or magmatic, in which minerals crystallize from a melt, (2) sedimentary, in which minerals are the result of sedimentation, a process whose raw materials are particles from other rocks that have undergone weathering or erosion, (3) metamorphic, in which … What are the 3 ways

Is sandstone clastic or non clastic?
Regional Specificsclastic sedimentary rocksclastic sedimentary rocks are sandstone and conglomerate. Some clastic sedimentary rocks (such as shale and mudstone) are fine enough that the individual grains cannot be distinguished. These fine-grained rocks are said to have an aphanitic texture. Is sandstone a clastic? Sandstone Basics The sediment particles are clasts, or pieces, of minerals and fragments

When was Continental Drift accepted?
Regional SpecificsThe first truly detailed and comprehensive theory of continental drift was proposed in 1912 by Alfred Wegener, a German meteorologist. Bringing together a large mass of geologic and paleontological data, Wegener postulated that throughout most of geologic time there was only one continent, which he called Pangea. When did continental drift become accepted? Wegener first
