Question

The word ‘Igneous’ is derived from the Latin word ‘ignis’ which suggests ------------.
A)- Soil
B)- Cold
C)- Magma
D)- Fire

Answer 1

Hint:Igneous rocks form when hot, molten rock crystallizes and solidifies. The melt originates deep within the world near active plate boundaries or hot spots, then rises toward the surface. Igneous rocks are divided into two groups, intrusive or extrusive, depending upon where the molten rock solidifies.

Complete answer:
Igneous rocks form when magma (molten rock) cools and crystallizes, either at volcanoes on the surface of the world or while the melted rock remains inside the crust. When lava comes out of a volcano and solidifies into extrusive rock, also called volcanically, the rock cools very quickly.
The melt originates deep within the world near active plate boundaries or hot spots, then rises toward the surface. The origin of fine-grained rock is magma or molten rock that erupts from a volcano within the sort of lava.
When molten lava cools down then igneous rocks are formed. Two sorts of igneous rocks are intrusive and extrusive.
Igneous rocks also are referred to as magmatic rocks. Igneous rocks are formed from the Latin word fire.

Hence, option D is the correct answer.

Note: Igneous rocks are formed from the solidification of magma, which may be a hot (600 to 1,300 °C, or 1,100 to 2,400 °F) molten or partially molten rock material.
• Most of the igneous forms include quite one mineral deposit.
• They are often either glassy or coarse.
• These usually don't react with acids.
