Is the Hawaii Volcano Still Erupting 2022?
GeologyAfter more than two years of quiescence, Kīlauea erupted again between December 2020 and May 2021 within Halemaʻumaʻu crater, where lava erupted from several vents boiled off a water lake that had been growing within the crater for more than a year, replacing it with a lava lake 229 metres (751 ft) deep. Is the
What is the difference between Slate and Quartzite?
GeologyIs Slate the same as quartzite? Slate has a fine to medium grained surface texture. It renders a very graceful, natural finish to any building or home. Quartzite can be cleft like slate, or can be smooth and more similar to marble and granite in appearance. What is the difference between slate and quartz? Quote
What are examples of divergent plate boundaries?
GeologyIn plate tectonics a divergent boundary is the boundary between two contiguous lithospheric plates that are separating. As the plates diverge, new material rises by magmatic processes from the Earth’s mantle, creating new lithosphere, so it is also called a constructive edge. The most active divergent edges are responsible for mid-oceanic ridges, where the mid-oceanic
What are you supposed to do in an earthquake?
GeologyIf you are able, seek shelter under a sturdy table or desk. Stay away from outer walls, windows, fireplaces, and hanging objects. If you are unable to move from a bed or chair, protect yourself from falling objects by covering up with blankets and pillows. What are the 5 things to do during an earthquake?
What forces magma upward?
GeologyA magma chamber is a large pool of liquid rock beneath the surface of the Earth. The molten rock, or magma, in such a chamber is less dense than the surrounding country rock, which produces buoyant forces on the magma that tend to drive it upwards. What causes magma to rise upward? Magma can rise

How do aretes cirques and horns form?
GeologyAn arête is a thin, crest of rock left after two adjacent glaciers have worn a steep ridge into the rock. A horn results when glaciers erode three or more arêtes, usually forming a sharp-edged peak. Cirques are concave, circular basins carved by the base of a glacier as it erodes the landscape. How are
Are Rocks always made of minerals?
GeologyNearly all rocks are made of minerals. A few are made of materials that do not fit the definition of minerals. Igneous rocks form from cooled magma or lava. Metamorphic rocks form as an existing rock is altered by high temperature or pressure. What rock is not made by minerals? Igneous rocks are rocks that
What are the different lithospheric plates?
GeologyThe lithosphere is divided into huge slabs called tectonic plates. There are eight major plates and several smaller plates, including the North American, Caribbean, South American, Scotia, Antarctic, Eurasian, Arabian, African, Indian, Philippine, Australian, Pacific, Juan de Fuca, Cocos, and Nazca plates. What are the 7 lithospheric plates? The World Atlas names seven major plates:
What rivers run through the Appalachian Mountains?
GeologyThe larger mountain streams to the south, dominated by the Tennessee River, follow this example. Exceptions are the rivers rising southeastward on the Blue Ridge, which flow into the Atlantic, and the Chattahoochee, rising in the northeastern corner of Georgia, which runs southwestward into the Gulf of Mexico. Is there a river near the Appalachian
