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

What is a quartz geode?

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 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

Why do earthquakes occur in certain areas?

Why do so many earthquakes originate in this region? The belt exists along boundaries of tectonic plates, where plates of mostly oceanic crust are sinking (or subducting) beneath another plate. Earthquakes in these subduction zones are caused by slip between plates and rupture within plates. Why do earthquakes occur in certain areas and not everywhere?
