Describe the Structure of the Earth

Mantle and core are the interior parts of the earth. 3core-it is the innermost layer of earth.

The thickness of the crust varies under the oceanic and continental areas.

. Structure of the Earth The crust is the outermost layer of the Earth. It is made mostly of oxygen silicon and the heavier element. Following is only an outline of major zones and shells of which the earth is believed to be made up.

The layer of the earth below the crust is called the mantle. The curst mostly consists of various kinds of rocks. It is mostly made of the lighter elements.

There are two types of crust continental and oceanic. It is composed of mainly nickel and iron. It is rich in silica.

Please mark as brainliest if you like it thank you. The Earth The structure of the Earth comprises of the crust mantle outer core and inner core. In preparing an answer for you I would refer to information on geodesy and geophysics and not Quora or Geography.

The mantle is hot and represents about 68 percent of Earths mass. Structure of the Earth. View the full answer.

Cutting the earth we would see. The structure of the Earths interior is divided into three layers namely the crust the mantle and the core. Crust mantle and core.

Describe how the structure composition and convection cycles of the Earth allows for tectonic plate movement a. Thin oceanic crust that underlies the ocean basins and thicker continental crust that underlies the continents. Core mantle and crust are divisions based on composition.

The mantle layer goes on till a depth of 2900 Km it extends from Mohos Discontinuity. The rubber ball represents the mantle below the crust and the steel ball inside is the earths core. Up to 24 cash back The Structure of the Earth The Earth consists of four concentric layers.

Earth has three main geological layers based on chemical composition crust mantle and core. The mud sticking unevenly on the outside of the ball represents the earths crust. Movement in the mantle caused by variations in heat from the core cause the plates to shift which can cause earthquakes and volcanic eruptions.

Of the Earth consists of the atoms silicon and oxygen. The structure of the earth is divided into four major components. Ridgid lithosphere moves independently of weak asthenosphere b.

Our planet is made up of three main layers. These two atoms are able to chemically react to form a number of molecules so not surprisingly the vast bulk of rocks on the surface of the Earth are made of silicates that is compounds formed from silicon. The Earths surface consists of a number of huge plates up to 100km thick which move at speeds between 2 and 15 cm a year.

The Earth is not flat spherical or ellipsoidal. The structure of the Earth. The ellipsoidal model is close to the shape but local variations due.

The following summarizes the Earths layers based on chemical composition or the chemical makeup of the layers. The crust and upper part of the mantle are broken into tectonic plates. The crust is a broad mixture of rock types with about 4 miles of thickness below the ocean and up to 40 miles below land.

Finally the core is mostly iron metal. Crust is the outer layer of the Earth where we live. Earth scientists have proposed that the Earth is constructed of layers.

Describe the structure of the Earth including the crust the mantle and the inner and outer cores. It is the skin of our Earth which ranges between 5 to 30 km. 1crust- it is the outermost layer of earth.

The crust is the outermost solid part of the earth. There are two types. Crust is the outermost layer of the earth.

Mantle drag resists plate subduction d. The outermost layer is the crust and is composed of mostly silicon oxygen aluminum iron and magnesium. Although the depth of continental crusts varies it averages around 30km in depth.

Volcanoes and earthquakes are largely the consequence of plate movement and often occur at the edges of these plates. Inner core outer core mantle and crust. Answer 1 of 3.

Earth is composed of many layers. 1 a very thin crust on the outside 2 a core of significant size in the center and 3 most of the mass of the Earth contained in the mantle. The crust makes up less than 1 percent of Earth by mass consisting of oceanic crust and continental crust is often more felsic rock.

The internal structure of the earth is like a steel ball that has been inserted into the middle of a rubber ball that has then been rolled around in the mud which sticks to it. It is the uppermost shell of the Earth that extends to variable depths below the mountains 75 km continents 35 km and oceans 5 km. Ridge push is a gravity-driven force that results from the elevated position.

It is the solid and rigid layer of the Earth. Each layer has a unique chemical composition physical state and can impact life on Earths surface. The structure of the earth can be divided into 3 parts crust mantle and core.

The outer part of the earth on which we live is called the crust. Oceanic crust is thinner as compared to the continental crust. Earths Crust There are two different types of crust.

The continental crust is thicker in. 2mantle- the layer below crust also called athenosphere. The uppermost part of the mantle.

Earthquakes and volcanoes are most likely to occur at plate boundaries. It is composed of molten rocks. The outermost structure of the Earth is defined as the Crust.

The Composition and Structure of Earth. This is high-density crust mo. It is made of solid rocks.

The crust mantle and core. Beneath the oceans the crust is at it thinnest extending only around 5km in depth. The crust the mantle the outer core and the inner core.

The mantle is the layer of the Earth right below the crust. The crust is thin and rigid. Friction between the overriding plate and the subducting plate resist plate motion c.

The structure of the Earth The Earth is made up of four distinct layers. The crust is made up of tectonic plates which are in constant motion. Contrast continental crust with oceanic crust.

While the earth was boiling in a molten form the lighter particles cooled at the top and formed the layer of crust. The internal structure of the Earth is divided into 3 parts ie. The Core The Crust.

The Mohorovicic discontinuity marks the lower boundary of the crust.
