Which sequence would be possible for a rock going through the rock cycle?
sdas [7]

D. metamorphic -> melting -> igneous -> erosion

Explanation:

The sequence that would be the best possible for a rock going through the rock cycle is metamorphic rocks melting to produce igneous rocks that are eroded.

  • The rock cycle shows the pathway by which different rock types are formed.
  • The origin of the formation of rocks starts with the production of magma.
  • Igneous rocks are formed from cooling and solidification of molten magma.
  • Metamorphic rocks are formed from the subjection of igneous and sedimentary rocks to high temperature and pressure.
  • Sedimentary rocks are formed from weathering, erosion, transportation and deposition of rocks.
  • Option D shows a metamorphic rock melting to give igneous rocks and the igneous rock is eventually eroded to form sedimentary rocks.
