Determine which characterisitics produce metamorphic rock vs sedimentary (1 point)
Sedimentary Metamorphic
Heat and pressure
Weathering and erosion
Igneous rocks under heat and pressure
Compaction and sedimentation
Heat and pressure: These characteristics produce metamorphic rocks. When pre-existing rocks are subjected to high temperatures and pressure, their mineral composition and structure can be altered, resulting in the formation of metamorphic rocks.
Weathering and erosion: These characteristics produce sedimentary rocks. When rocks are weathered (broken down into smaller fragments) and eroded (transported and deposited), the sediments can become compacted and cemented together over time to form sedimentary rocks.
Igneous rocks under heat and pressure: This characteristic does not produce either sedimentary or metamorphic rocks. Instead, it describes the process of forming metamorphic rocks from existing igneous rocks through the application of heat and pressure.
Compaction and sedimentation: These characteristics produce sedimentary rocks. Compaction refers to the squeezing together of sediments to reduce pore space, while sedimentation refers to the settling and accumulation of sediments over time, both of which contribute to the formation of sedimentary rocks.
