By mass, the Earth is composed of mostly iron (35 percent), oxygen (30 percent), silicon (15 percent), and magnesium (13 percent). It is made of distinct layers: a thin crust, upper mantle, lower mantle, outer core, and inner core, as well as transition zones. The crust is thinner under the oceans but thicker under the continents. While the inner core and crust are solid, the outer core and mantle layers are semi-fluid.
Most of the mass of the Earth is in the mantle, which is mostly made of the minerals olivene and pyroxene (iron and magnesium silicates). The elements calcium and aluminum are abundant in the upper mantle and while silicon, magnesium, and oxygen are major components of the lower mantle. The core is probably composed mostly of iron (perhaps with some nickel), where the temperature may be as high as 7227 °C (13,040 °F) at the center -- which is hotter than the surface of the Sun

What is the location of other layers of earth?
The Earth is composed of several layers, including the crust, mantle, outer core, and inner core. The crust is the outermost layer, located above the mantle, which extends to about 2,900 kilometers (1,800 miles) deep. Beneath the mantle lies the outer core, a liquid layer composed mainly of iron and nickel, followed by the inner core, a solid sphere at the Earth's center, reaching temperatures similar to the surface of the Sun.
What is The layer of gas surrounding earth composed mainly of nitrogen and oxygen?
The layer of gas surrounding Earth is called the atmosphere. It is primarily composed of nitrogen (about 78%) and oxygen (about 21%), with trace amounts of other gases such as argon, carbon dioxide, and water vapor. The atmosphere plays a crucial role in supporting life by providing oxygen, regulating temperature, and protecting the planet from harmful solar radiation.
Is the biosphere composed of all water on earth?
No it is not im not exactly sure where its from but i no its no fron the Biosphere
Why is Earth called the '' Blue Planet ''?
That's because it looks mainly blue, from space. With the clouds it looks like a blue marble.The Earth is called the "blue planet" because the surface is composed mostly of water. Over 70 % of the Earth's surface is water.Water looks blue from space mainly because it reflects the blue atmosphere.However, the full explanation is quite complicated.(A clear sky in daylight looks blue from the Earth's surface, because of the way white light is scattered by the air molecules.)
What zone or the earth is made up of liquid iron?
The Earth's outer core is composed of liquid iron & nickel
What gas covers most of the Earth?
Earth's atmosphere is composed mainly of nitrogen.
What is the Earth's core mainly composed of?
The Earth's core is mainly composed of iron and nickel. The outer core is in a liquid state, while the inner core is solid due to high pressure despite being at extremely high temperatures.
Inner planets that are composed mainly of rock and metal are called?
The inner planets composed mainly of rock and metal are Mercury, Venus, Earth, and Mars. These planets are also known as terrestrial planets due to their Earth-like composition.
Layer of gases surrounding earth composed mainly of nitrogen and oxygen?
The layer of gases surrounding Earth composed mainly of nitrogen and oxygen is called the atmosphere. It plays a crucial role in supporting life by providing the air we breathe and regulating the planet's temperature. The atmosphere also acts as a shield, protecting Earth from the harsh effects of radiation from the sun.
What is each layer of earth composed of?
Tectonic Plates
Which layer of the earth is composed mainly of solid iron?
The inner core of the Earth is composed mainly of solid iron. It is the innermost layer of the Earth, located beneath the outer core. The immense pressure at the center of the Earth causes the iron in the inner core to be solid despite its high temperature.
Is diatomaceous earth similar to limestone?
Diatomaceous earth and limestone are both sedimentary rocks composed of the remains of ancient organisms. However, they are chemically different. Diatomaceous earth is mainly composed of the silica cell walls of diatoms, while limestone is mainly composed of calcium carbonate from the shells and skeletons of marine organisms.
What are the two types of meteorites that hit earth?
The two main types of meteorites that hit Earth are stony meteorites and iron meteorites. Stony meteorites are composed mainly of silicate minerals, while iron meteorites are composed mainly of metallic iron-nickel.
What part of the Earth is rocky inorganic and mainly composed of different kinds of minerals?
The lithosphere is the rocky, inorganic outer layer of the Earth that is composed primarily of different minerals. It includes the Earth's crust and the upper part of the mantle.
What 2 chemicals was the Earth's first atmosphere composed of?
The Earth's first atmosphere was composed mainly of hydrogen and helium. These gases were eventually lost to space due to the Earth's gravity not being strong enough to hold on to them.
What section of earth is composed primarily of liquid metal?
The outer core of the Earth is composed primarily of liquid metal, mainly iron and nickel. This layer is responsible for generating Earth's magnetic field through the movement of this liquid metal.
What the difference between inner and outer core?
The inner core of the Earth is solid and composed mainly of iron and nickel. It is the Earth's innermost layer. In contrast, the outer core is a layer beneath the rocky mantle and is liquid in form. It is also composed mainly of iron and nickel, but its state allows for movement and generates the Earth's magnetic field.
