Which type of rock forms when molten material cools and hardens inside earth?
an igneous rock
an extrusive rock
a rock with fine texture
a rock with small crystals

Igneous rock

Explanation:

The answer is An igneous rock

Explanation:

Igneous rocks are those that form when magma (molten rock) cools and solidifies. If cooling occurs slowly below the surface, rocks with large crystals called plutonic or intrusive rocks are formed; Where magma, surrounded by pre-existing rocks, cools slowly, allowing minerals to form large crystals, visible to the naked eye.

there are mainly three domains in biological classification namely; archaea, bacteria, and eukarya.

archaea includes all the prokaryotic cells which are characterized by their lipid membranes. they have branched hydrocarbon which is attached to glycerol through an ether linkage.

bacteria includes all the prokaryotic cells, the cell membrane of which are made up of the unbranched fatty acid chain. in addition, they are attached to glycerol through an ester bond.

eukarya includes all the eukaryotic cells, that is, the cells contain a nucleus and other membrane-bound cell organelles.

they can be autotrophic as well as heterotrophic, unicellular as well as multicellular

they include kingdoms like protista, plantae, animalia, fungi et cetera.
