Answer 2

Answer:

The mantle is mostly composed of ‘silicate rocks’.

Explanation:

• The ‘mantle’ is the layer above the core and below the crust.
• It is characterized by ultramafic rocks peridotite that are silicate rocks mainly composed of magnesium and iron and also aluminium, calcium, potassium and sodium.
• Intense heat under the crust rises these rocks and later upon cooling, settles down in the sinks of the core.
• Silicates like olivine, pyroxene, and granite are found in the mantle.
