What is the main difference between the two layers of the mantle?
Chances are, you're on land right now. Scientists would say you are living on the sial. The sial is the part of the crust that is above water. It's a continental plate floating over the globe. Right underneath the sial is the sima. The sima is the layer of the Earth's crust that covers the entire planet. The sial is different in that it can begin and end where the plates do. You can think of the sima as the ocean floors. Under the sima is the mantle. When you consider the mantle is when you really start talking about the inner workings of the planet.
Why is the sima layer found beneath the sial layer?
The sial layer has a lighter density than the sima layer, which is due to increased amount of aluminium, and decreased amount of iron and magnesium.
What 2 layers make up the Earth's crust?
the earths crust and the rigid upper mantle
The earths crust is made of?
The Earth crust is made up with two layers known as " sial"and "sima". "sial" is the uppermost layer which composition is silica(si) and aluminum(al), that's why it is call "sial" and this layer comprises all the three rock types i. e. Igneous, sedimentary and Metamorphic rock. The second layer "sima" is formed with silica(si) and magnesium(ma). "sima' is generally composed of Basaltic rock.
What are the three layers of the mantle?
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
What is the abbreviation of SI MA?
The term SiMa and SiAl are now outmoded terms (usually just Sima and Sial) relating to the crust materials. Concepts dating from before sea floor spreading, and tectonic plates. Sial indicates rich in silica and aluminium, and with a specific gravity of about 2.7. Sima rocks contain silicon and magnesia, with an s.g. from 2.8 to 3.0. But including some ultrabasic rocks with an s.g. up tp 3.4. Sial will be lighter, and float on the heavier sima.

Where is the shield volcano located at?
Mid-oceanic ridges, at the divergance of 2 SiMa plates. Hawii is an example of a shield volcano.

What is the main type of rock oceanic plates are made from?
it is a mixture of volcanic rock or "cooled lava" and sedative rock

What is the type of crust formed on the ocean floor?
Oceanic crust, formed mostly of mafic rocks, or sima, is found on the ocean floor.
