  3. UNIT6 Formation of the different types of rocks Formation of magmatic rocks Magma (very hot masses of molten minerals) rises up slowly through the lithosphere towards the Earth’s surface. The magma that does not reach the surface cools down slowly and forms plutonic rocks. The magma that reaches the surface through volcanoes cools down quickly and forms volcanic rocks. 3 1 2 Go back to the start menu Natural Science 2. Secondary Education

  4. UNIT6 Formation of the different types of rocks Formation of metamorphic rocks High pressure and temperatures cause changes in these rocks that turn them into metamorphic rocks. Some rocks inside the lithosphere are subjected to great pressures and high temperatures. 2 1 Go back to the start menu Natural Science 2. Secondary Education

  5. UNIT6 Formation of the different types of rocks Formation of sedimentary rocks Wind and moving water beat away fragments of rocks and transport them. The fragments sink to the sea floor as sediment. Over time they build up and form layers. When many layers are formed, the lower layers of sediment are compacted by the upper layers and are transformed into sedimentary rocks. 1 2 3 Go back to the start menu Natural Science 2.
