Second Layer of Earth's 3 Concentric Layers
- Magnesium and silicon make up the majority of SIMA's second-layer components.
- Silica and aluminum are the two main components of SIAL, the earth's crust's outermost layer. Iron and nickel make up the majority of the earth's innermost core, known as the NIFE.
- The exterior layer of rock on which people, animals, and plants can all dwell.
- A layer of magma made up of silicon, magnesium, and iron is called the mantle.
- Inner core: a solid metal mass that is positioned in the center, and a liquid mass of iron and nickel (outer core).
- The intima (inner layer), media (middle layer), and adventitia (additional layer) are three concentric layers that can be seen (outer layer). Collagen-based components are present in all three layers, and muscle is present in the media layer (muscle cells and elastin).
What is the name of the second layer of the Earth's three concentric layers? (a) SIAL (b) SIMA (c) NIFE (d) No option is correct
The second of the Earth's three concentric layers is known as SIMA. Between SIAL (the crust) and NIFE, the second of the Earth's three concentrically structured layers, SIMA, also referred to as the "mantle," is located (core).
