Question

Which of the following is the correct order as we move towards the interior of the earth.

विकल्प

• SIAL - SIMA - NIFE

• NIFE - SIMA - SIAL

• NIFE - SIAL - SIMA

• None of the above

Answer 1

SIAL - SIMA - NIFE

Explanation:

The correct order as we move towards the interior of the Earth is:

• SIAL (Silica and Aluminium) forms the continental crust and is the outermost layer.
• SIMA (Silica and Magnesium) forms the oceanic crust and is located beneath the SIAL layer.
• NIFE (Nickel and Iron) forms the core, which is the innermost part of the Earth.

Thus, the correct sequence from the Earth's surface to the core is SIAL - SIMA - NIFE.
