Match each metamorphic rock with the correct parent rock. 1. quartzite limestone 2. marble sandstone 3. slate shale
vladimir1956 [14]

<u>Answer</u>:

  1. Quartzite - sandstone
  2. Marble - limestone
  3. Slate - shale

<u>Explanation</u>:

  • <em>Metamorphic</em> rocks are named after the term metamorphism, which means 'to change'. These rocks are called so because they change from one form to another due to several external factors.
  • <em>Parent rocks</em> are the original rocks from which the metamorphic rocks are formed after undergoing changes.
  • Sandstone, limestone, and shale are all sedimentary rocks which change their form due to high heat, pressure, temperature, and chemical activity and form their respective metamorphic rocks.
  • Thus, <em>sandstone, limestone, and shale are parent rocks and quartzite, marble and slate are the respective metamorphic rocks formed from them.</em>
