Maria wrote the following steps in the formation of igneous rocks. Step 1 : Rocks pushed under earth due to movement of tectonic plates step 2: rocks melt Step 3: molten rocks are heated step 4: rocks solidify Which step contains an error?

I think is the step 4

Step 3 is wrong

Explanation:

According to Maria molten rocks are heated up. This statement is incorrect because molten rocks are already heaten up. In the formation of igneous rocks, these molten rocks must be cooled to form igneous rocks. Igneous rocks are formed through the cooling and solidification of magma or lava. So rocks are pushed into the earth then they are melted. Once melted they come out of the earth through volcanoes and the lava then colds itself to form igneous rocks.
