What determines the type of volcanic eruption?
GeologyThe 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
How are minerals and rocks alike and different?
GeologyA mineral is a naturally occurring substance with distinctive chemical and physical properties, composition and atomic structure. Rocks are generally made up of two of more minerals, mixed up through geological processes. How are rocks and minerals similar and different? Rocks do not have a definite chemical composition whereas minerals do. Sometimes a rock may
What is a real life example of erosion?
GeologyExample of erosion: Wind carries small pieces of rock away from the side of a mountain. Chemical Weathering: – Decomposition of rock and soil due to chemical reactions. Mechanical Weathering: – Decomposition of rock and soil due to mechanical forces (pushes and pulls). What are erosion 5 examples? Agents of erosion include rainfall; bedrock wear
What makes a good reservoir rock?
GeologyGood reservoir rocks, by implication, must possess high porosity and permeability. A high proportion of open pore spaces enhances the capacity of a reservoir to… What kind of rock is good for reservoir? sedimentary rocks All types of rock (igneous, sedimentary, metamorphic) can act as reservoir rocks if it can accommodate and drain hydrocarbons. Reservoir
What is spodumene used for?
GeologySpodumene is an important source of lithium, for use in ceramics, mobile phone and automotive batteries, medicine, Pyroceram and as a fluxing agent. As of 2019, around half of lithium is extracted from mineral ores, which mainly consist of spodumene. What are the uses of spodumene? Spodumene is an essential supply of lithium to be
How does paleomagnetism relate to seafloor spreading?
GeologyThe symmetric banding is the result of seafloor spreading on both sides of a mid-oceanic ridge. This explanation of magnetic striping by paleomagnetism convinced scientists that new oceanic crust was being continually formed at mid-oceanic ridges. Seafloor spreading was accepted as a reality. How is paleomagnetism used to study ocean floor? Mapping of the seafloor
Is there a volcano in Los Angeles California?
GeologyIs there a real volcano in Los Angeles? There are no volcanoes in Los Angeles. The closest volcanic activity is the Lavic volcanic field and Coso volcanic field. Are there any volcanoes in Los Angeles County? The closest volcanic area to Los Angeles is the Coso Volcanic Field that lies just north of Ridgecrest, California,
Is basalt smooth or rough?
Geology‘A’a basalts have rough surfaces (that make barefoot people cry, “Ah! Ah!” as they walk across it). They form from fast flowing lava. Pahoehoe basalts have a smooth glassy surface that looks like many ropes. What is the texture of basalt? Basalts show, almost always, aphanitic or fine-grained mineral texture resulting from rapid cooling of
What is mined in subsurface mining?
GeologyUnderground mining (or subsurface mining) Underground mining is best suited to extract minerals that are located deep under the surface of the earth. Common minerals extracted using underground mining include gold, lead and silver. What are three resources that can be mined using subsurface mining? The deepest mine on Earth are up to 3.5 km
What is the absolute dating method?
GeologyAbsolute dating methods measure the physical properties of an object itself and use these measurements to calculate its age. One of the most useful absolute dating methods for archaeologists is called radiocarbon dating. It works by measuring carbon isotopes, which are versions of the element carbon. What are 3 methods of absolute dating? Absolute dating
