When and how do earthquakes occur?
Regional SpecificsThe tectonic plates are always slowly moving, but they get stuck at their edges due to friction. When the stress on the edge overcomes the friction, there is an earthquake that releases energy in waves that travel through the earth’s crust and cause the shaking that we feel. When and where do earthquakes usually occur?
What is a plate science?
Regional SpecificsWhat is a plates in science? A tectonic plate (also called lithospheric plate) is a massive, irregularly shaped slab of solid rock, generally composed of both continental and oceanic lithosphere. Plate size can vary greatly, from a few hundred to thousands of kilometers across; the Pacific and Antarctic Plates are among the largest. What is
Is Yellowstone about to explode?
Regional SpecificsAlthough another catastrophic eruption at Yellowstone is possible, scientists are not convinced that one will ever happen. The rhyolite magma chamber beneath Yellowstone is only 5-15% molten (the rest is solidified but still hot), so it is unclear if there is even enough magma beneath the caldera to feed an eruption. Is Yellowstone going to

What events happened during Cenozoic Era? What major events happened in the Cenozoic Era? Cenozoic Era major
Which type of foliation does phyllite have?
Regional SpecificsPhyllite has good fissility (a tendency to split into sheets). Phyllites are usually black to gray or light greenish gray in color. The foliation is commonly crinkled or wavy in appearance. Does phyllite have foliation? Phyllite is a foliated metamorphic rock rich in tiny sheets of sericite mica. It presents gradation in degree of metamorphism
What are the main parts of a glacier?
Regional SpecificsGlaciers have two main sections: the accumulation area and the ablation area. The accumulation area is where temperatures are cold and snow collects, adding mass to the glacier. The ablation area is where temperatures are warmer, so some of the glacier melts. What are the 3 parts of a glacier? Glaciers are classifiable in three
