Which statement best explains why gneiss is composed of layers but there are no layers in granite? a. gneiss is a sedimentary rock and granite is a metamorphic rock. b. gneiss is a metamorphic rock and granite is a sedimentary rock. c. granite is formed due to the slow cooling of magma below earth's surface and gneiss is formed due to metamorphosis. d. granite is formed due to the accumulation of sediments and gneiss is typically formed due to intense heat and pressure.

The granite rocks are formed by the slow crystallisation of the magma below the earth surface, due to slow crystallisation of the magma, the rocks formed are uniform, and have no layers.

The gneiss rocks are formed by the metamorphosis of the granite and the sedimentary rocks. They are formed by the action of high temperature and high pressure. The gneiss rock is layered caused by the segregation of different types of rock, mainly made up of light and dark silicates.

Hence, the correct answer is option

C. Granite is formed due to the slow cooling of magma below Earth's surface and gneiss is formed due to metamorphosis.

it would be the percentage of food eaten by the flock

i remember doing this lab

characterization of nanoparticles is a critical step in nanomaterial production as it provides information of dimension, morphology, surface charge, distribution and degree of surface functionalization.
