Lithosphere is the layer clostest to the earths crust. It is the layer that contains the sial and sima. Asthenosphere is the next layer clostest to the earths crust. Mesosphere is the inner most layer of the mantle than it goes to the core... Outer core, and inner core.I learned about it in school XD
Oceanic crust, formed mostly of mafic rocks, or sima, is found on the ocean floor.
The earth's interior is called the core.
It's ... um, denser. The continents (largely SiAl, silicon-aluminium) essentially "float" on the denser SiMa (silicon-magneisum) layer.
Earths crust is the outer shell of our planet. The Earth has two types of crust. Continental crust contains igneous, sedimentary and metamorphic rocks that covers the continents. Oceanic crust contains igneous basalt rocks derived from the upper mantle that cover the all the ocean floors. The igneous rocks are covered with sediments carried into the oceans from large rivers like the Amazon and Mississippi Rivers.
The oceanic crust is made up of mafic rocks which is rich in magnesium and iron. These rocks are also referred to as sima. The oceanic crust is similar to the continental crust, except it is thinner yet denser.
sial and sima - sial is surface crust on land, made of silicate and aluminium. sima is the deep crust found in oceans, made of silicate and magnesium
Sial consists of the minerals silicon and aluminium and it is the outermost lighter part of the crust. while sima consists of the minerals silicon and magnesium and it is the lower part of the crust.

Earths outermost layer is the crust.Actually, the crust is divided into two parts,Sial and Sima.In that way, actually Sial is the outermost layer of the crust,as it lies above the Sima.
Oceanic crust, formed mostly of mafic rocks, or sima, is found on the ocean floor.
The oceanic crust composed of sima, mafic rocks and basalt. This is the top layer of the lithosphere which is found in the ocean floor.

The lowest spots in the Earth's crust are found in the Mariana's Trench. It is located in the floor of the western North Pacific Ocean
