What are 3 of Earth's layers are found in 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.I learned about it in school XD
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.
What are the division of lithosphere?
Upper lithosphere, containing the continental crust/plate, known as the SiAl, and the Lowwer lithosphere composed of the oceanic crust/plate also reffered to as SiMa.
What is obtained by studying earths interior?
The earth's interior is called the core.
How is the density of ocean crust different that continental crust?
It's ... um, denser. The continents (largely SiAl, silicon-aluminium) essentially "float" on the denser SiMa (silicon-magneisum) layer.
What is the ocean's crust made up of?
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.
In earth's crust what are two types of crust?
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
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 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.

Earth's outermost layer is the?
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.
What is the difference between sima and sial?
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.
The lower boundary of earth's crust is called what?
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
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.
The oceans crust is composed of what?
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.
