How are the asthenosphere and the lithosphere different?
GeologySummary. The lithosphere is the brittle crust and uppermost mantle. The asthenosphere is a solid but it can flow, like toothpaste. The lithosphere rests on the asthenosphere. What is the difference between the Earth’s lithosphere and asthenosphere quizlet? The lithosphere and the asthenosphere are both parts of a mantle and parts of the interior earth.

What is the volcanic explosivity index vei of a Yellowstone super eruption?
Geology88, the largest recorded value on the index. What is the VEI of Yellowstone? Explosivity (Volcanic Explosivity Index) – 8. Top of the scale – Yellowstone has had three of the largest eruptions known over the past 3 million years; only beaten by Toba in Indonesia, which erupted about 74,000 years ago. Each of these
What is the movement of tectonic plates called?
GeologyThe heat from radioactive processes within the planet’s interior causes the plates to move, sometimes toward and sometimes away from each other. This movement is called plate motion, or tectonic shift. What are the three movements of tectonic plates? Movement in narrow zones along plate boundaries causes most earthquakes. Most seismic activity occurs at three
What are the three main types of sedimentary rocks?
GeologySedimentary rocks are formed from pieces of other existing rock or organic material. There are three different types of sedimentary rocks: clastic, organic (biological), and chemical. Clastic sedimentary rocks, like sandstone, form from clasts, or pieces of other rock. What is the difference between the 3 types of sedimentary rocks? Clastic sedimentary rocks are made
What is a quartz geode?
GeologyQuartz Geode Geodes are spherical rocks with hollow lines that are often associated with quartz crystals. The quartz geode is the most well-known form of geode. What are quartz geodes good for? It is also known as a purifying and recharging stone. Quartz crystals can also bring healing energy within yourself and into your home.

Why is magma formed from partial melting?
GeologyBecause the mantle is composed of many different minerals, it does not melt uniformly. As minerals with lower melting points turn into liquid magma, those with higher melting points remain as solid crystals. This is known as partial melting. How is magma formed from partial melting? The magma that is produced by partial melting is
What is the definition of a parent rock?
Geology and GeographyWhat is the definition of a parent rock quizlet? parent rock is the rock type that a metamorphic rock was before it was subjected to metamorphic conditions. You just studied 21 terms! What is a parent rock simple definition? In the earth sciences, parent rock, also sometimes substratum, is the original rock from which younger
What would happen if Mt Shasta erupted?
GeologyFuture eruptions like those of the past could endanger the communities of Weed, Mount Shasta, McCloud, and Dunsmuir, located at or near the base of Mount Shasta. Such eruptions will most likely produce deposits of lithic ash, lava flows, domes, and pyroclastic flows. What would happen if Mount Shasta blew? If Shasta erupted, it could
