How Heat and Pressure Transform Igneous and Sedimentary Rocks

Discover how heat and pressure can change igneous and sedimentary rocks into metamorphic rocks.

Heat and pressure can transform igneous and sedimentary rocks into metamorphic rocks. Under intense heat, rocks can melt partially, altering their mineral composition and texture. Pressure from tectonic forces causes rocks to recrystallize without melting, creating new minerals and textures.

FAQs & Answers

  1. What are the main types of rocks in the rock cycle? The main types of rocks are igneous, sedimentary, and metamorphic.
  2. How do sedimentary rocks form? Sedimentary rocks form from the accumulation and compaction of mineral and organic particles.
  3. What types of pressure affect rock formation? Burial pressure from overlying sediments and tectonic pressure from tectonic plate movements affect rock formation and transformation.
  4. Can igneous rocks become sedimentary rocks? Yes, igneous rocks can erode into sediments which may eventually become sedimentary rocks.
