- 19. LESSON PROPER Rock cycle is a web of processes that outlines how each of the three major rock types—igneous, metamorphic, and sedimentary—form and break down based on the different applications of heat and pressure over time. For example, sedimentary rock shale becomes slate when heat and pressure are added.
- 20. Igneous (from the Latin word for fire) form when hot, molten rock crystallizes and solidifies. The melt originates deep within the Earth near active plate boundaries or hot spots, then rises toward the surface. Sedimentary these rocks often start as sediments carried in rivers and deposited in lakes and oceans. When buried, the sediments lose water and become cemented to form rock. Metamorphic started out as some other type of rock, but have been substantially changed from their original igneous, sedimentary, or earlier metamorphic form. Metamorphic rocks form when rocks are subjected to high heat, high pressure, hot mineral-rich fluids or, more commonly, some combination of these factors.
- 21. Cooling and Crystallization Deep within the Earth, temperatures can get hot enough to create magma. As magma cools, crystals grow, forming an igneous rock. The crystals grow larger if the magma cools slowly, as it does if it remains deep within the Earth. If the magma cools quickly, the crystals will be very small. Weathering and Erosion Weathering is the breaking down or dissolving of rocks and minerals on Earths surface. Once a rock has been broken down, a process called erosion transports the bits of rock and minerals away. Water, acids, salt, plants, animals, and changes in temperature are all agents of weathering and erosion Metamorphism the changes in mineral assemblage and texture that result from subjecting a rock to pressures and temperatures different from those under which the rock originally formed.

- 23. What processes create igneous rock? What processes create sedimentary rock? What processes create metamorphic rock? Cooling and crystallization Erosion, weathering, dissolution and lithification Forms when rocks are subjected to high heat, high pressure, some combination of these factors.

Form 4 groups with 5 member each, the paper has a corresponding sentence, the first student must relay the message to the members then the last student must write the message to the board then answer the sentence question. The team that relays and answer the message correctly gains a point. Relay the message D. APPLICATION
- 25. Summary The three main rock types are igneous, metamorphic, and sedimentary The three processes that change one rock to another are crystallization, metamorphism, and erosion and sedimentation. Any rock can transform into any other rock by passing through one or more of the processes. This creates the rock cycle.
- 26. Evaluation Get a ¼ sheet of paper and answer the following question. 1. Is a series of processes that create and transform the types of rocks in Earth’s crust? 2. _______ is the breaking down of dissolving of rocks and minerals on earth surface. Once a rock has been broken down, a process called ________transports the bits of rocks and minerals away. 3. Refers to the cycle processes by which the sediment is moved along 4. _______ is when sediment is pushed together by the weight of water and other sediment pushing down on it. _______ are the process whereby dissolved minerals in the water between the grains crystallize cementing the grains together. 5. Is the process where rocks are altered due to pressure and/or heat, changing their appearance entirely.
