Question

which is the thinnest layer of the earth

Answer 1

Before moving one to answer our question, let's learn about the Earth's layers.

There are three layers of Earth. Which are as follows :

(i) Crust

(ii) Mantle

(iii) Core

$\boxed{\bold{\pink{Crust:}}}$

• Crust is the uppermost layer of the Earth.

• It's composed of many igneous, metamorphic and sedimentary rocks.

• It is just like a thin covering of the Earth 'bout 8 kilometres.

• It's thick 'bout 32 kilometres in oceanic crust and continental crust.

• But the Crust is thick in mountainous areas 'bout 70 kilometres.

$\boxed{\bold{\pink{Mantle:}}}$

• Mantle is the middle layer of the Earth.

• Mantle is made up of rocks and ices.

• Mantle is the largest layer and is most massive layer of the Earth.

• Mantle contains all the elements which are found on Earth.

Mantle is 'bout 2,900 kilometres thick which is found between Crust and Core.

 

$\boxed{\bold{\pink{Core:}}}$

• Core is the innermost part of the Earth.

• Core is a ball - like structure inside the Earth.

• Core is the hottest part of the Earth.

• Core is 'bout 1250 km thick.

• The radius of the core is approximately 1,220 kilometres.

Now, when we compare the thickness of all the three layers, we found that,

Thickness of Mantle > thickness of Core > thickness of Crust

Therefore, from the above relation we can conclude that,

$\boxed{\mathsf{\bold{\pink{Crust\:is\:2\:the\:thinnest\:layer\:of\:the\:Earth.}}}}$

Answer 2

Answer:

Crust is the thinnest layer of the Earth

Explanation:

"The Earth can be divided into four main layers: the solid crust on the outside, the mantle, the outer core and the inner core. Out of them, the crust is the thinnest layer of the Earth, amounting for less than 1% of our planet's volume."
