Seismologists discovered that most of the Earth's mantle is solid by analyzing seismic wave data generated by earthquakes. When seismic waves travel through the Earth, their speed and behavior change depending on the material they pass through. The observation that primary (P) waves, which can travel through solids, move faster than secondary (S) waves, which can only travel through solids, indicated that the mantle is primarily solid. Additionally, the reflection and refraction patterns of these waves provided further evidence of the solid nature of the mantle.
What else can I help you with?
What part of the mantle is most solid?
The most solid part of the mantle is the lower mantle, which extends from about 660 kilometers to 2,900 kilometers beneath the Earth's surface. In this region, the immense pressure causes the rocks to behave more like a solid than a liquid, despite being composed of semi-solid materials. The lower mantle is characterized by its high density and rigidity, contrasting with the more ductile behavior of the upper mantle, where the asthenosphere allows for some flow.
What is the layer that makes up most of the earth's mass and vloume is the is what?
The layer that makes up most of the Earth's mass and volume is the mantle. It is located between the Earth's crust and core and is composed of solid rock that is capable of flowing over long periods of time. The mantle is divided into the upper mantle and the lower mantle, with the upper mantle being partially molten and the lower mantle being solid.
What is most of the earths mass in?
Most of the mass of the Earth is in the mantle, most of the rest in the core; the part we inhabit is a tiny fraction of the whole
Which of earths spheres have the most mass?
The core of the Earth. This is because it is molten iron.
Which of earth's layers is the thickest and contains most of earth's mass?
The mantle is the thickest layer of Earth, consisting of solid rock that makes up about 84% of the Earth's total volume. This layer is also where most of Earth's mass is concentrated, as it extends from the crust to the outer core.
Which part of earth's mantle is the most solid?
The most outer solid portion of the planet Earth is the crust.
What part of the mantle is most solid?

Which layers of the earth contains rocks?
The rocks are primarily found in the Earth's crust, mantle, and core. The crust is the outermost layer and consists of solid rock. The mantle is composed of solid and semi-solid rock, while the core is mostly made of metal.
Where are most seismologists found?
Universities and the USGS.
Most of Earth's volume is contained in the?
Most of Earth's volume is contained in the mantle, which is the layer between the crust and the core. The mantle makes up about 84% of Earth's volume and is composed of solid rock that can flow slowly over long periods of time.
Which layer contains most of the earths mass?
The Mantle
Who were some famous seismologists?
Some famous seismologists include Charles Richter, who developed the Richter magnitude scale for measuring earthquakes, and Inge Lehmann, who discovered Earth's inner core. Hiroo Kanamori is also renowned for his contributions to understanding earthquake mechanisms.
Why is the Earth's mantle solid?
Yes, the mantle is techincally a solid. If you want to get techincal, however, it is a viscoelastic material, meaning that over short invertvals it behaves as an elastic solid, but over the course of tens of thousands to millions of years it flows like a viscous liquid.
What types of rock is in the mantle?
the mantle is made up of solid hot rock.
What is the most expansive layer of the Earth?
The most expansive layer of the Earth is the mantle, which makes up about 84% of the Earth's volume. It is located between the Earth's crust and the core and consists of solid rock that can flow slowly over long periods of time.
What are three layers of the earth from the most outer to the most inner?
The three layers of the Earth from the outermost to the innermost are the crust, the mantle, and the core. The crust is the Earth's outer shell, the mantle is a semi-solid layer beneath the crust, and the core is the Earth's innermost layer, consisting of a solid inner core and a liquid outer core.
