Question

Hi. could someone please answer this properly, i'll give brainliest.

a. i. What is the crust and what are the two different types
ii. explain what the lithosphere is.

b. explain what the mantle is

c. explain what the core is

Answer 1

Answer:

Mark as brainlist, give a like to it and follow me

That will be really very sweet of you!

Explanation:

1 Earth's crust is divided into two types: oceanic crust and continental crust. The transition zone between these two types of crust is sometimes called the Conrad discontinuity. Silicates (mostly compounds made of silicon and oxygen) are the most abundant rocks and minerals in both oceanic and continental crust.

2 the rigid outer part of the earth, consisting of the crust and upper mantle.

3 The most well-known feature associated with Earth's lithosphere is tectonic activity. Tectonic activity describes the interaction of the huge slabs of lithosphere called tectonic plates. ... The division in the lithosphere between the crust and the mantle is called the Mohorovicic discontinuity, or simply the Moho.

4 At the center of the Earth is the core, which has two parts. The solid, inner core of iron has a radius of about 760 miles (about 1,220 km), according to NASA. It is surrounded by a liquid, outer core composed of a nickel-iron alloy.

Answer 2

Answer:

Earth's crust is divided into two types: oceanic crust and continental crust. The transition zone between these two types of crust is sometimes called the Conrad discontinuity. Silicates (mostly compounds made of silicon and oxygen) are the most abundant rocks and minerals in both oceanic and continental crust.

Earth's lithosphere includes the crust and the uppermost mantle, which constitute the hard and rigid outer layer of the Earth. The lithosphere is subdivided into tectonic plates. ... The lithosphere is underlain by the asthenosphere which is the weaker, hotter, and deeper part of the upper mantle.

The lithosphere is the outermost 'sphere' of the solid Earth, consisting of the crust and the upper part of the mantle.

The mantle is the mostly-solid bulk of Earth's interior. The mantle lies between Earth's dense, super-heated core and its thin outer layer, the crust. The mantle is about 2,900 kilometers (1,802 miles) thick, and makes up a whopping 84% of Earth's total volume.

Earth's core is the very hot, very dense center of our planet. The ball-shaped core lies beneath the cool, brittle crust and the mostly-solid mantle. The core is found about 2,900 kilometers (1,802 miles) below Earth's surface, and has a radius of about 3,485 kilometers (2,165 miles).
