Title: The Interior of the Earth 1 The Interior of the Earth. By Crystal Mason; 2 The Layers of the Earth 3 The Crust. The crust is a very thin layer of earth when compared to the other layers. It is only five to twenty-five miles thick on. a continental plate and three to five miles on an ocean plate. The crust is divided into twelve plates. Mars' core has twice the concentration of lighter elements than the Earth, and is probably made from iron, nickel and sulphur (a lighter element) and is partially fluid. The mantle and crust are both made from silica rich rocks.; Mars crust is much thicker than Earth, between 50 - 125 km deep (compared to Earth's average of 40 km - see diagram below).

MANTLE second layer of the interior of the earth. Two sub - layers –1. Upper mantle. 2. Lower mantle. Thickness varies between 35km – 2900 km. Average density is 4.5 g/cm3 Upper portion of mantle and crust together known as Lithosphere. lower mantle – Aesthenosphere. 12.

Interior of the earth diagram. At the planet’s center lies a dense metallic core. Scientists know that the core is metal for a few reasons. The density of Earth’s surface layers is much less than the overall density of the planet, as calculated from the planet’s rotation. If the surface layers are less dense than average, then the interior must be denser than average. Complete the scale model slice of the Earth by drawing arcs at the appropriate radii corresponding to the Moho, Lithosphere-Asthenosphere, Transition Zone, Core-Mantle, and Outer Core-Inner Core boundaries as given in Table 1 and illustrated on the Earth’s Interior Structure diagram (Figure 2). A well-known and simplified diagram of the interior of the Earth: image courtesy of the Univ. Nevada Reno This diagram shows us how thin the crust is in relation to the rest of the Earth, along with relative sizes of the mantle and core. Interestingly, there are two cores noted (the inner

The interior of the earth can reveal the nature of lithosphere. A knowledge of earth’s interior is essential for understanding plate tectonics. Hence, this lesson is about the interior of the Earth. THE INTERIOR OF THE EARTH By Eugene C. Robertson ABSTRACT Evidence on the structure and composition of the earth's interior comes from (1) observations of surface rocks, (2) geophysical data from earthquakes, flow of heat from the interior, the magnetic field, and gravity, (3) laboratory ex This diagram shows the different layers found inside the Earth. Click on image for full size Windows Original. Structure of the Interior of Earth Earth has a diameter of about 12,756 km (7,972 mi). The Earth's interior consists of rock and metal. It is made up of four main layers:

• Meteors: These are not from the interior of the earth but the material and the structure observed in the meteors are similar to that of the earth. This make them another source of information about the interior of the earth. • Gravitation force: It is greater near the poles and less at the equator. A cut-away illustration of Earth's interior. At the heart of our planet lies a solid iron ball, about as hot as the surface of the sun. In this article (geography section), we discuss the interior of the earth. Understanding the basic structure of earth is very important to learn higher concepts well. Also, the origin of many phenomena like earthquakes, volcanoes, tsunami etc are linked with the structure of earth's interior. What should you understand about the interior of the earth?

The interior structure of the earth is composed of three main layers: Inner core, outer core, mantle and crust. The core is composed mostly of iron (Fe) and is so hot that the outer core is molten, with about 10% sulphur (S). The inner core is under such extreme pressure that it remains solid.

The Earth's interior Three major layers Three major layers inside the Earth interior are the crust, mantle and the core. Scientists divide the mantle into the upper and lower mantle. The core is divided into a liquid outer core and a solid inner core. Earthquake waves used to find Earth's interior layers It is impossible for drilling equipment. The Inner Earth is composed of three main parts, sometimes called the layers of the earth; the crust, the mantle, and the core as shown in the diagram of the earths interior below: The Crust - silicate rocks, primarily granite and basalt.

Geodesy, GE 202 Kutubuddin ANSARI kutubuddin.ansari@ikc.edu.tr Lecture 3, Oct 11, 2016 Interior of the Earth 2. •The Earth's mass is about 5.98 x 1024 kg. • Earth is the densest planet in our Solar System (mass/volume). •Earth is made of several layers with different compositions and physical properties.

Sesmic activity: This gives most important evidences of interior of earth. Earthquakes give a fair idea of interior of earth. We shall look into the details of Earthquake laters on. Structure of Earth. I. The Crust: It is the outermost solid and brittle part of the Earth. Oceanic crust is thinner – 5 km mean thickness. 2.2 STRUCTURE OF THE EARTH’S INTERIOR The above diagram (see fig. 2.1) shows the concentric layers of the earth’s inte-rior. The innermost layer surrounding the earth’s centre is called core, which is about 3500 kms in radius. Core is the most dense layer of the earth with its density The structure of the Earth is divided into layers.These layers are both physically and chemically different. The Earth has an outer solid layer called the crust, a highly viscous layer called the mantle, a liquid layer that is the outer part of the core, called the outer core, and a solid center called the inner core.The shape of the earth is an oblate spheroid, because it is slightly.

The Earth's crust ranges from 5–70 kilometres (3.1–43.5 mi) in depth and is the outermost layer. The thin parts are the oceanic crust, which underlie the ocean basins (5–10 km) and are composed of dense () iron magnesium silicate igneous rocks, like basalt.The thicker crust is continental crust, which is less dense and composed of sodium potassium aluminium silicate rocks, like granite. The Earth's interior is composed of four layers, three solid and one liquid—not magma but molten metal, nearly as hot as the surface of the sun. The deepest layer is a solid iron ball, about. Being so deep inside the earth, the temperature and pressure of the lower mantle are extremely high. Here in the lower mantle, the convection currents allow heat from the interior of the earth to rise to the surface. 4. Outer Core. Temperature: 4,300 K (4,030°C) in the outer regions to 6,000 K (5,730°C) closest to the inner core

Other important data on the Earth's interior come from geological observation of surface rocks and studies of the Earth's motions in the Solar System, its gravity and magnetic fields, and the flow of heat from inside the Earth. The planet Earth is made up of three main shells: the very thin, brittle crust, the mantle, and the core; the mantle.
