What are the 4 types of lava?
GeologyBecause of the role of silica in determining viscosity and because many other properties of a lava (such as its temperature) are observed to correlate with silica content, silicate lavas are divided into four chemical types based on silica content: felsic, intermediate, mafic, and ultramafic. What are the 3 main types of lava? There are
Does the earth open up during an earthquake?
GeologyDoes the earth open up during an earthquake? No! A common misconception is that of a hole in the ground that opens during an earthquake to swallow up unfortunate victims. This has nothing to do with reality but is Hollywood’s version of earthquakes. Can the ground open up during an earthquake? Shallow crevasses can form
What is made out of igneous rock?
GeologyIgneous rocks have a wide variety of uses. One important use is as stone for buildings and statues. Diorite was used extensively by ancient civilizations for vases and other decorative artwork and is still used for art today (Figure 1). Granite (figure 2) is used both in building construction and for statues. What are 5

Is volcanic ash a sedimentary rock?
GeologyVolcanic ash is, obviously, an igneous rock: it comes out of volcanoes, and you can hardly get more igneous than that. As such, you might be surprised to find an article on volcanic ash dropped into a chapter which is otherwise about sediment and sedimentary rocks. What type of rock is volcanic ash? Tuff Tuff
What type of plate boundary is the San Andreas Fault?
Geologytransform plate boundarytransform plate boundary that disrupts the topography of an ancient subduction zone. What plate boundary is the San Andreas Fault on? transform plate boundary Tectonic Plate Boundaries The Pacific Plate (on the west) slides horizontally northwestward relative to the North American Plate (on the east), causing earthquakes along the San Andreas and associated
What is cement to a geologist?
Geologycementation, in geology, hardening and welding of clastic sediments (those formed from preexisting rock fragments) by the precipitation of mineral matter in the pore spaces. It is the last stage in the formation of a sedimentary rock. What is the difference between cement and Matrix? Matrix is the relative finer grained sized sedimentary particles in
What is a geological resource?
GeologyBased on this definition, geological resources can be defined as the accumulation of rock, metal and non-metal mineral resources, coal, peat, solid bitumen, oil, natural gas, geothermal, and the environment (water and soil) existing in the earth’s crust, both on the surface and below the surface, and are able to be … What is a
How is a mid ocean ridge formed?
GeologyMid-ocean ridges occur along divergent plate boundaries, where new ocean floor is created as the Earth’s tectonic plates spread apart. As the plates separate, molten rock rises to the seafloor, producing enormous volcanic eruptions of basalt. How are mid-ocean ridges formed for kids? The mid-ocean ridge is formed where two tectonic plates meet under the
