Igneous rock is formed by the cooling and solidification of molten earth materials. igneous rock forms when magma or lava cools. if underground pockets of magma and solidify, igneous rock is formed, such as granite.

If underground pockets of magma __cools and solidify, intrusive igneous rock is formed, such as granite.

The correct answer is cools and intrusive.

Intrusive  igneous rock is formed when magma cools slowly below the Earth's surface. The slow look cooling allows for the formation of large crystals which are visible to the naked eye, such as the large crystal seen in granite.

Extrusive  igneous rock is formed when magma cools rapidly above the Earth's surface. The quickly cooling leads to the formation of very small crystals.

we can conclude that the melting point of table salt is above room temperature (it's actually 801 deg c). the melting point of mercury must be below room temperature (- 39 deg c).
