How Does Subduction Turn Sedimentary Rocks into Magma?

Discover how subduction transforms sedimentary rocks into magma through tectonic processes.

The process that turns sedimentary rocks into magma is called subduction. When tectonic plates collide, the denser plate is forced beneath the other into the mantle, where it melts due to high temperatures and pressures. This melted material can eventually rise to the surface, forming magma.

FAQs & Answers

  1. What is subduction in geology? Subduction is the geological process where one tectonic plate moves under another and sinks into the mantle.
  2. Can sedimentary rocks become magma? Yes, sedimentary rocks can become magma through the process of subduction, where they are subjected to extreme heat and pressure.
  3. What happens to rocks during subduction? During subduction, rocks are exposed to high temperatures and pressures, causing them to melt and form magma.
  4. How does magma rise to the surface? Magma rises to the surface due to its lower density compared to surrounding rock, often resulting in volcanic eruptions.
