WebIgneous rocks. The word ‘igneous’ comes from the Latin word ignis, meaning fire. At plate boundaries, or hot spots, some rocks get heated deep inside the Earth and melt into ‘molten rock’. Molten rock is called magma when it is inside the Earth and lava when it is on the surface. As it cools, it crystallises and solidifies to form igneous rock. WebJan 5, 2024 at 8:30.

So the first "rocks" on Earth must have been "igneous" (developed from a firey or molten state).
WebMetamorphic Rocks. Metamorphic rocks are any rock type that has been altered by heat, pressure, and/or the chemical action of fluids and gases. Metamorphic rocks are classified by their structure and their dominant minerals. Metamorphic rock structure is either foliated (has a definite planar structure) or nonfoliated (massive, without structure).
WebU-235 is found in most igneous rocks. Unless the rock is heated to a very high temperature, both the U-235 and its daughter Pb-207 remain in the rock. A geologist can compare the proportion of U-235 atoms to Pb-207 produced from it and determine the age of the rock. The next part of this exercise shows how this is done.
