Answer:
(1)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 mant
(2)Two parts of the upper mantle are often recognized as distinct regions in Earth's interior: the lithosphere and the asthenosphere. The lithosphere is the solid, outer part of the Earth, extending to a depth of about 100 kilometers (62 mile
(3)The core–mantle boundary of the Earth lies between the planet's silicate mantle and its liquid iron-nickel outer core. This boundary is located at approximately 2891 km depth beneath the Earth's surface.
(a)Earth's inner core is the innermost geologic layer of the Earth.
(b) crust
(c)Although the core and mantle are about equal in thickness, the core actually forms only 15 percent of the Earth's volume, whereas the mantle occupies 84 percent. The crust makes up the remaining 1 percent.
(d)
The crust is the uppermost layer over the earth's surface which is about 35 km on the continental masses and only 5 km on the ocean floors. The mantle has been just beneath the crust, which is extended up to a depth of 2900 km. below the crust. The innermost layer is the core, with a radius of about 3500 km.
Answer:
Ocean crust is the upper most layer...
