Sial, primarily composed of silica and alumina, is found in the Earth's crust, specifically in the continental crust. It forms the upper layer of the Earth's mantle and is prevalent in continental landmasses. The term "sial" often refers to the lighter, granitic rocks that make up the continents, contrasting with "sima," which refers to the denser, basaltic rocks of the oceanic crust. Sial is associated with various geological formations, including mountains and continental plates.

Why is the sima layer found beneath the sial layer?
The sima layer is found beneath the sial layer because it is denser and rich in magnesium and iron minerals, making it heavier. This difference in composition and density creates the stratification of Earth's crust, with sima underlying sial.
What is sial layer and where is it found?
The sial layer is the outermost layer of the Earth's crust, made up of sedimentary rocks and soil materials. It is typically found near the Earth's surface and varies in thickness depending on location.
Where do sial live?
Sial, or the "sial" layer, refers to the lighter, less dense part of the Earth's crust primarily composed of silicate minerals. This layer is found in continental crust, which underlies landmasses and is distinct from the denser oceanic crust known as "sim." Sial is primarily located beneath continents and mountainous regions, contributing to the formation of landforms and geological structures.
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 is Sial?
Sial is a surface glycoprotein found mainly in vertebrates, aiding in cell-to-cell recognition and immune response. It plays a role in various biological processes, including cell signaling, adhesion, and protection against pathogens. Sialic acid is a common component of mucins and is often targeted by pathogens for attachment and invasion.
