We dont have your requested question, but here is a suggested video that might help. Q. Seismic wave reflection has helped scientists identify: The general compositions, respectively, of the upper continental crust, lower continental crust, and ocean crust are: Information about the mantle comes primarily from: How do scientists know that the outer core is not pure iron? But, understanding how matter and energy behave in surface waves is an important step towards earthquake safety. (a) Within what distance from the speaker would the sound be painful to the ear? A. Lithosphere is made of molten rocks. (Source: US . A surface wave is a wave that moves along the interface of two different materials, like air and water. Which factor does the moment magnitude scale estimate? This radiative ground wave is known as Norton surface wave, or more properly Norton ground wave, because ground waves in radio propagation are not confined to the surface. An error occurred trying to load this video. However, earthquakes are also defined as the shaking that such an event produces.

They can travel through outer space. Surface waves can travel around the globe many times from the largest earthquakes. The cosmic microwave background ( CMB, CMBR) is microwave radiation that fills all space. Surface waves only travel through the crust level while S waves travel through the core of the earth (hence called body waves). der Physik und Chemie, vol. A wave transfers its energy to a material. For example, the next time you go swimming, place your ear in the water, have a friend hit the wall on the opposite side of the pool and see if you can hear the sound. Correct answers: 1 question: Which statements describe surface waves? Which strategy do geologists use to locate the center of an earthquake? c.
