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

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.


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.
