1}What are the inner igneous rock ?
2} Where are the rocks used?
3}Which minerals are mainly composed in SiAL layer?
​

Answer 1

Answer:

1-igneous rock forms when magma is trapped deep inside the Earth.

2-Making Cement (Limestone) (Sedimentary Origin) Writing (Chalk) (Sedimentary Origin) Building Material (Sandstone) (Sedimentary Origin) Bath Scrub (Pumice) (Igneous Origin)

3-The main mineral constituents of the continental mass are silica and alumina. It is thus called sial

Answer 2

Questions:-

1}What are the inner igneous rock ?

2} Where are the rocks used?

3}Which minerals are mainly composed in SiAL layer?

Answers:-

1}Intrusive, or plutonic, igneous rock forms when magma is trapped deep inside the Earth. ... Intrusive rocks have a coarse grained texture. Extrusive Igneous Rocks: Extrusive, or volcanic, igneous rock is produced when magma exits and cools above (or very near) the Earth's surface.

• Making Cement (Limestone) (Sedimentary Origin)
• Writing (Chalk) (Sedimentary Origin) Building Material (Sandstone) (Sedimentary Origin)
• Bath Scrub (Pumice) (Igneous Origin)

3} The main mineral constituents of the continental mass are silica and alumina. It is thus called SiAl (Si - Silica and Al - alumina or aluminum).
