2 #1As magma cools, it forms igneous rock by the process of solidification.
3 Igneous rocks can form sediments, magma, and metamorphic rocks. #2Igneous rocks can form sediments, magma, and metamorphic rocks.
4 #3Sediments form sedimentary rocks by the process of deposition, compaction (burial), and cementation.
5 Sediments form from the process of weathering and erosion. #4Sediments form from the process of weathering and erosion.
6 Sedimentary rocks can form magma, sediments, and metamorphic rocks. #5Sedimentary rocks can form magma, sediments, and metamorphic rocks.
7 #6Which process changes igneous rock into metamorphic rock? heat and/or pressure also known as metamorphism
8 #7Which process changes sedimentary rock into igneous rock? melting into magma then solidification
9 #8Which process changes metamorphic rock into sedimentary rock? weathering and erosion into sediments and then compaction or cementation
10 #9Metamorphism involves the addition of heat and pressure to pre-existing rocks.
11 Compaction & cementation of sediments forms sedimentary rocks. #10Compaction & cementation of sediments forms sedimentary rocks.
12 #11Subjecting sedimentary rocks to extreme heat & pressure forms metamorphic rocks.
13 Solidification of molten materials forms igneous rocks. #12Solidification of molten materials forms igneous rocks.
14 Deposition and burial of sediments forms sedimentary rocks. #13Deposition and burial of sediments forms sedimentary rocks.
15 #14Deposited sediments may be particles of which types of rock? Metamorphic, sedimentary or igneous rocks
16 Heat & pressure acting on igneous rocks forms metamorphic rocks. #15Heat & pressure acting on igneous rocks forms metamorphic rocks.
17 Solid magma forms igneous rocks. #16Solid magma forms igneous rocks.
18 #17In order to form magma, what must happen to sedimentary, metamorphic or igneous rocks? They have to melt
19 #18For weathering & erosion to occur, what process will the rock usually go through first or at the same time? uplift
20 #19Can sedimentary rock form directly from metamorphic rock? Explain your answer.
21 #19 contd.No, it must either weather and erode to form sediments that are compacted or cemented into sedimentary rock OR follow through the cycle of melting into magma, solidifying into an igneous rock, breaking apart into sediments, then compacted or cemented into a sedimentary rock.
