Question

which type is metamorphic rock formed from limestone?
clay
shale
sandstone
marble

Explanation:

Metamorphic rocks are formed from pre - existing rocks through metamorphism. Limestone is a sedimentary rock. When limestone undergoes metamorphism (due to heat and pressure), it changes its mineral composition and texture. Marble is the metamorphic rock that forms from limestone. Clay is a sedimentary material, shale is a sedimentary rock (formed from clay and silt), and sandstone is also a sedimentary rock (formed from sand - sized particles).

Answer:

marble
