2.Oceanic crust
3. The innermost layer
4. The uppermost layer
5. Core has high pressure and
6 The layer beneath the crust​

Answer 1

Answer:

1.crust and mantle, thecore is made almost entirely of metal—specifically, iron and nickel. The shorthand used for thecore's iron-nickel alloys is simply the elements' chemical symbols—NiFe. Elements that dissolve in iron, called siderophiles, are also found in thecore.

2.Oceanic crust is the uppermost layer of the oceanic portion of a tectonic plate. It is composed of the upper oceanic crust, with pillow lavas and a dike complex, and the lower oceanic crust, composed of troctolite, gabbro and ultramafic cumulates. The crust overlies the solidified and uppermost layer of the mantle.

3.The innermost layer of the earth is known as the core. It is divided intoinner core and outer core. It comprises of a high concentration of nickel and iron.

4.The Earth's crust is not a huge single piece. It is fragmented into pieces.

5.The inner core is a hot, dense ball of (mostly) iron. It has a radius of about 1,220 kilometers (758 miles). ... The innercore's intense pressure—the entire rest of the planet and its atmosphere—prevents the iron from melting. Thepressure and density are simply toogreat for the iron atoms to move into a liquid state

6.The crust and the upper layer of themantle together make up a zone of rigid, brittle rock called the Lithosphere. The layer below the rigid lithosphereis a zone of asphalt-like consistancy called the Asthenosphere . Theasthenosphere is the part of themantle that flows and moves the plates of the Earth.
