Metamorphic rocks are formed when rocks are subjected to warmth, tension, or both heat and pressure. Metamorphic rocks typically form at plate boundaries and next to intrusions of magma. Sedimentary rocks are formed from weathered bits of rocks (sediments). These sediments are deposited into levels. The burden of overlying layers compact the layers of sediment beneath, and water flowing with the layers deposits minerals that cement the grains together.
An exciting and interactive way to bolster the identification of various types of rocks is thru a rock scavenger hunt. In this article’s tips on how to Manage this outside action: 1.

discusses the types of rock or the rock cycle and their near marriage to the theory of plate tectonics.

It's not at all shocking, then, that metamorphic rocks form at convergent and transform plate boundaries. Metamorphic rocks that sort in this way have commonly establish a foliated texture (wavy layers).
Metamorphic rocks are shaped from current rocks that go through a approach named metamorphism. This method includes making use of heat and stress to the existing rocks, creating them to change in texture, structure, and mineral composition.
