Where is the Moho discontinuity?
GeologyMoho, or Mohorovičić discontinuity, boundary between the Earth’s crust and its mantle. The Moho lies at a depth of about 22 mi (35 km) below continents and about 4.5 mi (7 km) beneath the oceanic crust. Modern instruments have determined that the velocity of seismic waves increases rapidly at this boundary. Where is the Moho
What characterizes a divergent boundary?
GeologyA divergent boundary occurs when two tectonic plates move away from each other. Along these boundaries, earthquakes are common and magma (molten rock) rises from the Earth’s mantle to the surface, solidifying to create new oceanic crust. The Mid-Atlantic Ridge is an example of divergent plate boundaries. What is the characteristic of divergent boundary? When
Ist Basalt ein Naturstein?
GeologyBasalt gilt als der Naturstein, der am meisten verbreitet ist – sei es an der Erdoberfläche oder auf dem Meeresgrund. In den Tiefen des Meeres bestehen fast alle Böden aus dem Material, wobei sich die einzelnen Basalttypen in ihrer chemischen Zusammensetzung unterscheiden. Was ist Basalt für ein Stein? Basalt ist ein basisches (kieselsäurearmes) Ergussgestein. Es
What type of plate boundary caused the 1964 Alaska earthquake?
Geologyplate convergenceplate convergence: where the Pacific Plate is being overridden by the North American Plate, it descends, or subducts, into the Earth’s mantle along the Aleutian Trench. What boundary was the 1964 Alaska earthquake? The 1964 Alaska earthquake resulted from rupture along the thrust fault boundary bet- ween the downgoing Pacific Plate and the overriding
What is geo mapping Wikipedia?
GeologyFrom Wikipedia, the free encyclopedia. Geovisualization or geovisualisation (short for geographic visualization), also known as cartographic visualization, refers to a set of tools and techniques supporting the analysis of geospatial data through the use of interactive visualization. What is mapping in geography? Maps present information about the world in a simple, visual way. They teach
What does it mean when your hematite ring breaks?
GeologyAre hematite rings supposed to break? Third, you need to remember that hematite rings in general are very fragile; drop them and they shatter because hematite is that brittle. It’ll never scratch, which is a bonus, but remember to be careful anyway. All of that being said, this is an okay deal. What do you
What is meant by Mohra week discontinuity?
GeologyMoho discontinuity is defined as the boundary between Earth’s crust and the mantle, observed by a sharp increase in the velocity of the seismic waves passing through the Earth. The name Mohorovicic discontinuity was received from Croatian geophysicist Andrija Mohorovičič, in 1909. What is Mohra week discontinuity? The Mohorovicic Discontinuity marks the lower limit of
Was there an earthquake last night in San Jose?

What is the point on the surface nearest the earthquake?
Geology and GeographyThe hypocenter is the point within the earth where an earthquake rupture starts. The epicenter is the point directly above it at the surface of the Earth. What is the point on the surface where the earthquake is the strongest? Surface damage In most earthquakes, the epicenter is the point where the greatest damage takes
Why is it difficult for an organism living in the rainforest to become a fossil?
GeologyIt is difficult for an organism living in a rain forest to become fossilized. The large amount of rain throughout the year causes rapid decay of dead organisms. Also, many scavengers and decomposers work quickly to break down the tissues and structures of rain forest life. 6. What are three reasons why many organisms never
