Why is Earth’s crust broken into pieces?
GeologyAnswer and Explanation: The Earth is broken into plates to allow recycling materials amid the crust and the mantle. Earth crust and the top part of the mantle are broken into enormous pieces known as tectonic plates. Why is the crust broken into pieces? Because large convection cells of hot magma in the mantel keep
How are continental glaciers different from Valley?
GeologyValley glaciers can flow in all directions as they move, while continental glaciers move down slopes already cut by rivers. Valley glaciers cover much of a continent, while continental glaciers cover a small area of mountains. Continental glaciers are long and narrow, while valley glaciers are wider in size. How are valley glaciers different from
Where can igneous rocks be found?
GeologyIgneous 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. Where can you find igneous rocks? Where Igneous Rocks
What is the parent rock of basalt?
GeologySome metamorphic rocks form due to contact metamorphism, as a result of heat from a nearby intrusion of magma.… Foliated Metamorphic Rocks Crystal Size medium to coarse Mineralogy biotite, muscovite, quartz, garnet, plagioclase Parent Rock shale, basalt Metamorphism medium grade regional Rock Name schist What is the parent rock of granite? Metamorphic Rock Classification Parent
What does Mercalli mean?
GeologyWhat is the definition of a Mercalli scale? Definition of Mercalli scale : a scale of earthquake intensity ranging from I for an earthquake detected only by seismographs to XII for one causing total destruction of all buildings. What is a Mercalli wave? The Mercalli intensity scale is a seismic scale used for measuring the
Does the San Andreas Fault run through Palmdale?
GeologyThe San Andreas runs deep near and under some of California’s most populated areas. The cities of Desert Hot Springs, San Bernardino, Wrightwood, Palmdale, Gorman, Frazier Park, Daly City, Point Reyes Station and Bodega Bay rest on the San Andreas fault line. Where does the San Andreas Fault run in Palmdale? Running along the north
What is a Belemnite fossil?
GeologyDelaware State Fossil (Belemnitella americana) Belemnite is the common name applied to an extinct order (Belemnoida) of mollusks belonging to the cephalopod class. Modern cephalopods include the squid, octopus, and pearly Nautilus. What did belemnites look like? Belemnites are probably the most common fossils found on the beaches, especially around Charmouth. When the animal was
How does the Moho relate to the asthenosphere?
GeologyHow does the Moho relate to the asthenosphere lithosphere? The MOHO is a place where seismic P-waves suddenly increase in velocity, presumably because they are able to travel faster through the denser mantle rocks. … The MOHO is NOT the lithosphere-asthenosphere boundary. Rather, the MOHO is the crust-mantle boundary. Is Moho and asthenosphere same? No.
How are metamorphic rocks classified quizlet?
GeologyHow are metamorphic rocks classified? Metamorphic rock is classified by texture and composition. The texture can be foliated or nonfoliated. How are metamorphic rocks classified? Metamorphic rocks are broadly classified as foliated or non-foliated. Non-foliated metamorphic rocks do not have aligned mineral crystals. Non-foliated rocks form when pressure is uniform, or near the surface where
What is angularity in geology?
GeologyRounding, roundness or angularity are terms used to describe the shape of the corners on a particle (or clast) of sediment. Such a particle may be a grain of sand, a pebble, cobble or boulder. What is the definition of angularity of soil? Angularity describes the aggregate particle with regard to changes of the corner
