How are the asthenosphere and the lithosphere different?

Summary. 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?

88, 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?

The 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?

Sedimentary 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

Why is magma formed from partial melting?

Because 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?

What would happen if Mt Shasta erupted?

Future 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
