2. A rock with folds and interlocking crystals is likely to be a __________________________ rock. Group of answer choices Igneous intrusive Igneous extrusive Sedimentary Metamorphic
Igneous rock
Igneous rocks are formed from the solidification of magma either above the surface or below it. Igneous rocks are characterised by an interlocking grain texture.
The absence of fossils, bedding planes and layerings qnre characteristic features of an igneus rock.
Sedimentary rocks-
Sedimentary rocks are formed from the deposition of the broken fragments in the ocean basin. The deposition of the sediments and their digenesis produces sedimentary rocks. Sedimentary rocks are layered and bedding planes are present.
They are characterised by having fossils.
Metamorphic rocks-
These are solid state transformations of pre-existing rocks. Here temperature and pressure play an important role in the formation of metamorphic rocks. They are devoid of any fossils and bedding plants.
