The crust is the outermost layer of the earth making up 0.5-1.0 per cent . The rock in the asthenosphere is low density and partially molten. Asthenosphere: The "weak sphere" - is the soft layer of the mantle where pieces of the lithosphere move. David is passionate about quality-focused journalism and has worked in the publishing industry for over 10 years. See Answer Question: Question 19 (1 point) Which of the following best describes the asthenosphere? It sits above the boundary between the upper and lower parts of the mantle. Approximately how long ago did the Big Bang take place? Oil briefly rose after a Reuters news alert on Saudi Arabia extending a voluntary output cut. 1. Which of the following is not one of the four inner planets? The asthenosphere is mostly solid, but its able to flow. The Earth can be divided into four main layers: the solid crust on the outside, the mantle, the outer core and the inner core. It is a layer of solid rock where the extreme pressure and heat cause the rocks to flow like a liquid. The asthenosphere is about 180 km thick. So the convection currents in the asthenosphere are assumed to be responsible for these relative motions. melting, crystallization, heat and pressure hot and weak, transform fault The asthenosphere is hot and weak hot and strong cool and. Sedimentary rocks, which are made from bits of other rocks that have been cemented together, can be any color depending on what minerals are present. The material in the asthenosphere is thought to be partially molten, meaning that it consists of both solid and liquid phases. When did geologists develop the theory of plate tectonics. Heat from deep within Earth is thought to keep the asthenosphere malleable, lubricating the undersides of Earths tectonic plates and allowing them to move. all of the above, can form by life-processes -- organic igneous This website helped me pass! gravitational attraction and collisions All other trademarks and copyrights are the property of their respective owners.

The asthenosphere is the layer of the Earth that lies below the lithosphere. The asthenosphere is the hot, viscous layer of the Earth that lies beneath the lithosphere. As the temperature of the material increases or as the pressure exerted on the material increases, the material tends to deform and flow. metamorphism At the top of the asthenosphere, the low-velocity . The asthenosphere is thought to be the source of magma for volcanoes. Features useful in defining plate boundaries include all except: The age of the Earth is currently thought to be. The name asthenosphere comes from the Greek word for weak, because this layer is weaker and more pliable than the lithosphere above it. The motions of the three types of plate boundaries would be described as divergent, convergent, and static.

The lithosphere includes Earth's crust and the uppermost mantle. OPTION B IS CORRECT. none of the above, the recognition that processes still active today could produce almost any known rock type. The upper mantle is made of many different minerals, but the most common ones are olivine and pyroxene.The temperatures in the upper mantle range from about 700 degrees Celsius near the crust to over 4000 degrees Celsius near the core-mantle boundary. D) A hypothesis cannot predict the outcome of scientific experiments. Two mechanisms of formation of asthenospheric layers., Your email address will not be published. Its like a teacher waved a magic wand and did the work for me. The upper boundary is usually around 1300 degrees Celsius. The asthenosphere is also known as the low velocity zone of the mantle because seismic waves slow down as they pass through it. During this movement of plates, pressure on the asthenosphere is reduced, melting occurs, and molten materials flow upward to Earths surface. Molten Earth cools, Earth aggregates, giant impact(s) occurs, Earth differentiates. Discuss with the whole class what the relative thicknesses of the layers are that the inner core and outer core together form the thickest layer of the Earth and that the crust is by far the thinnest layer. It is solid, but can flow like toothpaste. 2023 Caniry - All Rights Reserved The asthenosphere is a liquid layer in the mantle. subduction zone cool and weak combine to form helium. The reason why the Earths crust appears to be dark from space is because it is covered with a thick layer of atmosphere.The atmosphere blocks out most of the sunlight, making it appear dark from above.

The word asthenosphere comes from the Greek words for weak and sphere.The name reflects the fact that this layer of the mantle is weaker than the layers above and below it. These conditions make it difficult for scientists to study the composition and properties of this layer directly.Instead, they must use indirect methods such as seismology to infer its nature. The asthenosphere is a mechanically weak layer beneath the lithosphere characterized by low seismic wave velocities and high attenuation (Karato, 2012) (Fig. What is an interesting fact about the asthenosphere? - Designs & Definition, Lens Types: Simple, Compound & Other Types, Diffraction: Definition, Equation & Examples, Arthur B. McDonald: Biography & Nobel Prize, Working Scholars Bringing Tuition-Free College to the Community. It is much thicker than the crust and makes up most of the Earths mass.The mantle has a deep red color because of its iron content. This layer is around 1,800 miles (2,900 kilometers) thick and makes up a large portion of the Earths overall volume. Most of the earths mantle is rocks that are regarded as silicates. It is a layer of solid rock where the extreme pressure and heat cause the rocks to flow like a liquid. Asthenosphere: lower mantle, composed of plastic solid akin to playdoh. . several centimeters per second, convergent 100-150 million years ago The asthenosphere is the hot, viscous layer of the Earth that lies beneath the lithosphere. The asthenosphere is important for plate tectonics because it is where convection currents occur. hot material flows upward and displaces cool material divergence The asthenosphere is thought to be aout 60-200 miles (100-300 kilometers) thick.
