Which types of rock are foliated metamorphic rocks? check all that apply. gneiss granite marble quartzite slate

((geneiss and slate))

ANSWER:

Gneiss and slate are foliated metamorphic rocks.

EXPLANATION:

Foliated metamorphic rocks are rocks with branded or layered appearance. It is formed as a result of direct and unequal pressure and exposure to heat. They usually have aligned texture and when break, they are found in layers and are parallel. Common examples may include gneiss, schist, phyllite and slate. Marble and quartzite are forms of non-foliated metamorphic rocks formed as a result of direct heat and pressure and are granular in appearance. Granite, though, granular in appearance is a form of igneous rocks.

Mantle convection is the process that drives plate tectonics. the theory of plate tectonics states that the crust is divided into plates that float on the semi molten mantle below. the circular motion of the magma as it slowly rises and falls or move though convection cells drags the plates along causing them to move. the heat source in the lamp would represent the earth's core. the core is the source of energy that drives convection in the mantle. the lava represents molten magma under the earth's surface. if the lava lamp had floating pieces they would move as the circular motion of the lava in the lamp as it rises and falls would move them along the surface. these floating pieces would represent pieces of the earth's crust.
