How does magma turn into extrusive igneous rock? How do minerals form from magma? What are chemical sedimentary rocks? How does quartzite form? How are metamorphic and igneous rocks alike and different? Why do metamorphic rocks form from regional metamorphism?
How does groundwater cause erosion and deposition? How does the cryosphere interact with the hydrosphere? How does weathering produce sediment? How do eastern boundary currents influence coastal climate? How does a frontal boundary cause wind shear?
238 Words 1 Page Open Document Tectonic Plate Formation While Earth’s plates continuously create new ocean floor and continental land, but also makes it disappear. At divergent plate boundaries, the plates push together and magma rises to the surface. When this magma cools it creates new plate...
Igneous rocks form when magma (molten rock) cools and crystallizes, either at volcanoes on the surface of the Earth or while the melted rock is still inside the crust. All magma develops underground, in the lower crust or upper mantle, because of the intense heat there. What causes nonconfo...
What are Igneous Rocks?Igneous rocks are made from magma from the earth’s core or other rocks that have melted, crystalized, cooled, and hardened. Some examples of igneous rocks are basalt, pumice, and granite. What are Sedimentary Rocks?Sedimentary rocks are made up of sediment, small piece...
Where do valley glaciers form? What is the difference between erosion and deposition? What are large boulders deposited by glaciers called? How does geology affect the formation of coastal landforms? What happens to the ground underneath a glacier? How do landforms from magma form and become expos...
The magma creates a new section of sea floor, which explained why the oceanic crust looked so young: It was continually emerging as a new floor. The newest rock was closest to the mountain range, with older rock located farther away, and each new layer reversed the magnetic polarity, explai...
Oceans of magma, Moon formation and Earth’s ‘Year Zero’ Posted onAugust 12, 2016byRon Miksha Interesting piece by Steve Drury on the attempts to define Earth’sYear Zero. Accuracy of a new model narrows the date to a rather narrow window. Reblogged onThe Mountain Mysterysite. ...
When we look to see how the Pacific Plate has moved steadily north, we’d expect to find evidence of the past equatorial line of sediment to the north. But scientists have been surprised to find something unexpected: the equator was not where we’d expect–and the only way that the equat...
How long does it take for sedimentary rocks to form? How are sedimentary rocks named? What are chemical sedimentary rocks? What processes can transform metamorphic rock into sediment? What three processes transform metamorphic and sedimentary rocks into sediment? How can you distinguish a clastic frag...
