Question

Lisa wrote the following steps in the formation of metamorphic rocks.

Step 1: Rocks pushed up onto Earth's surface due to movement of tectonic plates
Step 2: Rocks experience extreme heat and pressure
Step 3: Mineral composition of rocks changes
Step 4: Original rocks transform into a new rock

Which step contains an error?

Step 1
Step 2
Step 3
Step 4

Answer 1

The correct answer is Step 1: Rocks pushed up onto Earth's surface due to movement of tectonic plates.

The step 1 is the incorrect. It is because metamorphic rocks are formed on the surface of the Earth by the effect of heat and pressure on existing rocks. This can greatly affect the hardness, texture or layer patterns of the rocks. These rocks are changed by heat produced by nearby molten igneous rock. When the volcanoes erupt or release lava, the lava seeps inside the cracks of the rock and due to heat and pressure, forms a metamorphic rock.
