Exam 2 review

• Metamorphic rocks are formed from the transformation of pre-existing rocks through heat and pressure.
• Sedimentary rocks are formed from the accumulation and lithification of sediments, such as sand, silt, and clay.
• Metamorphic rocks are formed from the transformation of pre-existing rocks through heat and pressure.
• Sedimentary rocks are formed from the accumulation and compaction of sediments, such as sand, mud, and organic matter.
• Igneous rocks are formed from the solidification of molten material, either magma or lava.
• Rocks can be classified into three main types: igneous, sedimentary, and metamorphic.
• Metamorphic rocks are formed when existing rocks undergo intense heat and pressure, causing them to change in composition and texture.
• Weathering and erosion break down rocks into sediments, which can then be transported and deposited to form sedimentary rocks.
