Earth is made up of iron, magnesium, nickel, and rock. The crust is the outer layer, only 5-40 km thick. Is has two parts, oceanic crust and continental crust. Continental is made up of granite, while oceanic is made of basalt.
The mantle is the second layer of the earth. It has three parts to it: lithosphere, mesosphere, and ionosphere. This layer is about 3,000 km thick and is made up of iron and magnesium as well as rock. The mantle has millions of convection currents inside of it, helping form the magnetic field around the Earth's atmosphere.
Finally, there's the core. It has only two parts, called the inner and outer core. They are both made of iron and nickel. The outer core is a liquid layer that covers the solid ball of iron we call the inner core. The inner core is solid because of all the pressure and heat applied to it from the layers above, making it unable to become a liquid layer. Also, the outer core is the only layer that's liquid. The rest are solid.

What is the earth made up name the 3 major layers?
The Earth is composed of three major layers: the inner core, outer core, and mantle. The inner core is solid and made mostly of iron and nickel. The outer core is liquid and also composed of iron and nickel. The mantle is a solid rocky layer that surrounds the outer core.
What makes up earth's three major layers and the biosphere?
Earth's three major layers are the crust (solid outer layer), mantle (semi-solid middle layer), and core (solid inner layer). The biosphere is made up of the lithosphere (solid outer part of the Earth), hydrosphere (all water on Earth), and atmosphere (layer of gases surrounding Earth), where living organisms exist.
Is earth made up of layers of gases?
No, Earth is composed of solid layers such as the crust, mantle, outer core, and inner core. The atmosphere, which is a layer of gases, surrounds Earth.
What are the names of other two layers of the earth and what are they made of?
The other two layers of the Earth are the mantle and the core. The mantle is primarily composed of silicate minerals, while the core is mostly made of iron and nickel.
How did scientists figure that the earth was made of layers?
Scientists inferred that the Earth is made of layers through the study of seismic waves generated by earthquakes. By analyzing how these waves travel through the Earth, scientists were able to identify different layers based on variations in density, composition, and rigidity. This led to the development of the Earth's layered structure known as the crust, mantle, outer core, and inner core.
What is the earth made up name the 3 major layers?
The Earth is composed of three major layers: the inner core, outer core, and mantle. The inner core is solid and made mostly of iron and nickel. The outer core is liquid and also composed of iron and nickel. The mantle is a solid rocky layer that surrounds the outer core.
What are the 3 major layers of the earth differentiate each?
The three major layers of the Earth are the crust, mantle, and core. The crust is the outermost layer and is composed of solid rock. The mantle lies beneath the crust and is made up of solid but flowing rock. The core is the innermost layer and is believed to be mostly composed of iron and nickel.
Why do you think earth have layers?
The Earth has layers because it is made up of materials of varying density.
Is earth made of layers of crust?
Yes it is
Why do scientists believe that the earth is made up of different layers?
for the same reason that if you pour oil on top of a jar of water the oil stays on top. the layers of the earth have different densities and so the heaviest stuff sank to the center while the lighter stuff rose to the top.
What makes up earth's three major layers and the biosphere?
Earth's three major layers are the crust (solid outer layer), mantle (semi-solid middle layer), and core (solid inner layer). The biosphere is made up of the lithosphere (solid outer part of the Earth), hydrosphere (all water on Earth), and atmosphere (layer of gases surrounding Earth), where living organisms exist.
