Layers of earth?

Crust, lithosphere, mantle, outer core, and inner core. or oceanic crust, continental crust, lithosphere, mantle, molten core (outer), and solid core (inner).

What are the layers of the Earth?

Earth's Layers (All depths are from the surface of theEarth.) 1. The Crust--The outer skin of the planet is composed of igneous,metamorphic, and sedimentary rock. The crust is divided intocontinental or oceanic based on composition and formation. Continental Crust: Comprised predominantly of roc (MORE)

What is the middle layer of the earth called?

This question is somewhat vague! The middle or centre of the whole Earth is the core. However the middle of the layers from the surface to the centre of the Earth is known as the mantle.

What is the layer of air surrounding the earth called?

The air surrounding Earth is our atmosphere. The atmosphere is bound to Earth by gravity. Dry air contains (by volume) 78% nitrogen, 20.95% oxygen, .9% argon, 0.04% carbon dioxide, and other gasses in small amounts. Water vapor can vary, displacing these, and is typically 1% but can be several (MORE)

The top layer of the leaf thaat is waterproof is called what?

uhhhm. peanut butter?! (this question wanst answered before anyways, so don't be disspaointed.) First of all, this is NO help whatsoever. You don't need to be doing this, these are serious questions, and immature idiots like you don't need to be on here answering questions like this, this make (MORE)

Why does the earth have layers?

Looking at the whole earth is is layered with the densest materials in the core and the lightest materials forming the surface. This is because it was once molten and was therefore able to differentiate into density stratified layers. Looking in finer detail at the surface of the planet, the proce (MORE)

What is the layer of air that surrounds the Earth called?

The air surrounding Earth is our atmosphere. The atmosphere is bound to Earth by gravity. Dry air contains (by volume) 78% nitrogen, 20.95% oxygen, .9% argon, 0.04% carbon dioxide, and other gasses in small amounts.

Top layer of soil is called?

The top layer of soil where grass grows is called Humus. The nextlayer is the topsoil, and the layer after that is the subsoil.

What is in the layers of the earth?

minerals and such. each layer has different elements. crust: oxygen, silicon, aluminum, iron, calcium, sodium, potassium, magnesium mantle: magnesium, silicon, iron, and oxygen outer core: super-heated liquid molten lava, which is mostly made of iron, and nickel inner core: mostly of iron, a (MORE)

What is earth's top layer called that supports plant life?

The crust. but if you are talking upwards, it is the troposphere. the word part "tropo-" could be related to the word "tropical," which contains much life. the word part "-sphere" could be related to the geometric shape, which is the shape of the earth, and surrounds it.

Why is earth layered?

Heavier, more dense material, tended to sink in the early molten mass, while lighter, less dense material, rose toward the surface. Separation into layers was based on density. The separation seems to have taken place shortly after the formation of the planet in an event called the "Iron Catastrophe (MORE)

The top layer of soil is called what?

Layers of soil are called horizons and labeled as O, A, E, B, C,and R. The top layer or horizon is O. It is made up of organicmatter, and can be called topsoil.

Why earth has layers?

Geologists believe that Earth's layers separated because of their different densities. Shortly after Earth formed, 4.6 billion years ago, it was bombarded with meteorites. The impact of the meteorites created enough heat to melt some of Earth's rocks. Once these rocks melted, the densest materia (MORE)

What are layers of earth called?

In geology and related fields, a layer of rock or soil with internally consistent characteristics that distinguishes it from contiguous layers is a stratum (plural: strata).

The planet we call earth has how many layers?

there are 7 layers.. this is the following: Biosphere troposphere stratosphere mesosphere thermosphere ionosphere exosphere The boundaries between them are: Tropopause mesopause thermopause exopause

What is the center layer of earth called?

The very center of the Earth consists of the solid inner core(Ni-Fe alloy) and the liquid outer core (Ni, Fe) that spins and asa giant dynamo gives rise to the existence of the Earth magneticfield.

What are the layers are the earth?

The layers of the earth are the Crust, Mantle, Outer Core and the Inner Core. There is also a lithosphere in the mantle 100km below the Earth's Crust (top layer). Crust 0-40km below the surface Lithosphere 40-100km below the surface Mantle 40-2800km below the surface Outer Core 2800-5200km below th (MORE)

Why do people only live on the top layer of the earth?

W only live on the top layer because we werent placed on the earth any lower and it is way to difficult to dig that deep when we are perfectly fine where we are. Humans only live in a small band on the surface of the Earth because it is the most hospitable area to live in. You can't go too deep (MORE)

Where are the layers of the earth?

Layers of the Earth include the crust, mantle, outer core, andinner core. The inner core is made up of iron, nickel, and sulfurwhile the outer core is liquid.
