Which agents are necessary in the formation of metamorphic rocks? check all that apply. a. erosion b. heat c. lava d. pressure e. sediments

Metamorphic rocks are formed by the physical or chemical changes that occur in the existing igneous or sedimentary material. These are formed by process such as compression, shearing and stress forces, plate tectonics. These are formed by the erosional breakdown of the pre- existing rocks or because of the subduction of the sedimentary rocks under another plate or heat melting the rocks present in the earth's interior.

Therefore, agents which are necessary in the formation of metamorphic rocks are A. erosion, B.heat,  D.pressure and E. sediments.

Metamorphic rocks are formed as a result of heat and pressure.

a rain shadow is a dry region of land on the side that is protected against the prevailing winds of a mountain range. the prevailing winds are the winds that occur most of the time in a particular place of the earth

prevailing winds carry air toward the mountain range. as the air rises up over a mountain range, the air cools, water vapor condenses, and clouds form. on this side of the mountains, called the windward side, precipitation falls in the form of  rain  or snow. this dry air produces a  rain shadow.

its first and third is your answer i did the qustion the fourth isnt right
