What is the sequence of the layers in the Earth form the surface to the center?

The first layer is the crust, made up of both the Continental crust, which extends about 30 miles down from the surface, and the thinner Oceanic crust, at only 6 miles at its deepest. This layer is very cool and rocky, compared to the hot inner layers.
The Upper mantle is the next layer, extending from beneath the Continental and Oceanic crusts, and continuing down to the depth of 250 miles where it reaches the Transition region, or mesosphere.
This Transition region, which is extends from 250-400 miles below the surface of the Earth, is followed by the Lower Mantle, 1,275 miles thick, which contains chemicals such as Magnesium, Silicon, and Oxygen.
Beneath the Lower Mantle is the intensely hot, molten Outer core, 125-200 miles thick, and 3% of the Earth's mass.
The Inner core sits at the center of the Earth, where it reaches the final depth of 6,378 miles. This layer, unlike the boiling, liquid molten which comprises the Outer core, is solid and is suspended within the Outer core.

Which theory below explains why the Earth is composed of three layers of varying density?
When Earth was molten, heavier materials sank to the center as lighter materials rose to the surface.
How are earth layers formed?
sedimenatary rock create layers in the surface of the earth and eruptions from volcanoes also make layers of the earth.
Does the density increase or decrease in earth's layers?
Moving from the surface of the Earth toward the center, you will encounter increasing density. This is perfectly logical since denser matter will sink, and also because the weight of all the matter that is on top of the lower layers helps to compress them into an even denser form.
What is the distance from the surface of the earth to the center in km?
The average distance from Earth's surface at the equator its center is about 6378 km. The distance from near the north and south poles to the center is somewhat less.
What is the sequence where water passes through the atmosphere and on the earth's surface?
water cycle.
Is the sequence of earth's layers the same everywhere on the planet?
yes, the layers beneath earths surface are in the same sequence throughout earth, although certain parts of certain layers may be wider in certain places or slimmer, but they stay in the same sequence
Earth's layers can be defined by their chemical composition From surface to center what are these layers?
Crust, mantle, core
What is the order of the earth layers from the center to the surface?
crust, lithosphere,asthenosphere,lowermantle, outer core, inner core
What is the order of layers of earth from the surface to the center?
crust, lithosphere,asthenosphere,lowermantle, outer core, inner core
What theory explains why the Earth is composed of three layers of varying density?

Is the rocks layers near the surface of earth younger than rock layers further from the surface?
Yes.
What are the layers of the earth in order from the center to the outside of the planet?
What is the order of the center of the earth to the outside.

Compare and contrast the layers sun with of earth?
The earth's geological layers are (from center to outside)the core-which is mostly nickel and iron-, the mantle,-which is melted rock called magma-, and the crust, -which is composed of rocks, soil etc. The earth's atmospheric layers are (from surface out) the Troposphere, Stratosphere, Mesosphere, Thermosphere, and Exosphere. The sun's geological layers are (form center to outside) the inner core, the radiative zone, the convection zone, and the photosphere, which is the surface of the sun. The one atmospheric layer is the chromosphere, which contains the corona.
How does stress changes Earth's Surface?
stress changes the earth's surface by the way it looks and the layers.
What Circle on Earth's surface has the center of Earth as its center?
Any circle on the Earth's surface whose center is at the center of the Earth is called a "great circle". Any circle with its center anywhere else is called a "small circle". Spiritually, many consider the kaaba (Mecca) to be the center of the Earth's surface.
