The asthenosphere consists of many varieties of rock which is mostly in a semi molten condition. The temperatures in the asthenosphere reach levels high enough for most of the rock to become soft and plastic, capable of slowly moving while remaining in a solid state, while only about 10 percent is totally molten. The soft, plastic, but solid quality of the asthenosphere allows lithospheric plates to slide on top, resulting in the many earthquakes which occur in this region.
What else can I help you with?
What are earth's physical layers in sequence?
The Lithosphere, Asthenosphere, Mesosphere, outer core and Inner core.
What is the composition of the asthenosphere?
The asthenosphere is composed of partially molten rock material, mainly consisting of peridotite and basalt. It is located beneath the lithosphere and is responsible for the movement of tectonic plates due to its semi-fluid nature.
Are the Earth's 5 physical layers these Inner Core Outer Core Mesosphere Asthenosphere and Lithosphere?
The Earth's five physical layers are actually the Inner Core, Outer Core, Mantle, Asthenosphere, and Lithosphere. The Mantle is an additional layer between the Outer Core and the Asthenosphere, which plays a crucial role in Earth's structure and dynamics.
What is the difference between compositional layers and mechanical layers of the earth?
Compositional layers refer to the different layers of the Earth based on their chemical composition, such as the crust, mantle, and core. Mechanical layers, on the other hand, are based on the physical properties and how they behave under stress, like the lithosphere, asthenosphere, and mesosphere. The crust, mantle, and core are compositional layers, while the lithosphere, asthenosphere, and mesosphere are mechanical layers.
List the layers of earth by their chemical composition and by their physical properties?
by the chemical composition is: the crust, the mantle (upper mantle and mantle), and the core. (you can put inner or outer) by the physical property is: lithosphere, asthenosphere, outer core, inner core. hope i helped
How do physical properties of the asthenosphere support the ideas of continental drift and sea floor?
The asthenosphere allows tectonic plates to move
Does the athenosphere and core have the same density?
No, the asthenosphere and the core do not have the same density. The core is denser than the asthenosphere due to its composition of mostly iron and nickel. The asthenosphere is less dense because it is made up of partially molten rock.
How do the physical properties of the asthenosphere support the ideas of continental drift and sea floor spreading?
The asthenosphere allows tectonic plates to move
What are the two physical layers of earth?
The two densest physical layers of the earth are the lithosphere and the asthenosphere.
What type of rock is in the asthenosphere?
Matter in the Asthenosphere is in the molten or semi-molten state. This is because its temperatures can peak at 3,000 degrees Celsius. Its composition consists of magnesium and iron silicates. The Asthenosphere plays a key role in the movement of tectonic plates.
What are the two physical layers of the earth are densest?
The two densest physical layers of the earth are the lithosphere and the asthenosphere.
What are earth's physical layers in sequence?
The Lithosphere, Asthenosphere, Mesosphere, outer core and Inner core.
What are the 5 sub-layers of the earth?
The five sub-layers of the Earth are, from outermost to innermost: the lithosphere, asthenosphere, mesosphere (also known as the lower mantle), outer core, and inner core. These layers vary in composition, temperature, and physical properties, playing distinct roles in the Earth's structure and dynamics.
What best describes the physical nature of the earth's lithosphere and the asthenosphere?
The lithosphere is rigid and commonly deforms in a brittle manner; the asthenosphere tends to flow slowly and deform in a plastic manner.
What are the 5 physical layers of the earth?
Inner core, outer core, asthenosphere, lithosphere, and crust.
What is the composition of the asthenosphere?
The asthenosphere is composed of partially molten rock material, mainly consisting of peridotite and basalt. It is located beneath the lithosphere and is responsible for the movement of tectonic plates due to its semi-fluid nature.
What is the density of the asthenosphere?
The asthenosphere has a density that is slightly less than the overlying lithosphere. It is composed of hot, semi-fluid rock that allows the lithosphere to move and deform over it due to its lower density and viscosity. The exact density can vary depending on temperature, pressure, and composition of the material.
