The Story of Rocks
Long after Earth formed its layers,the planet began to cool.

The surface hardened. Melted rock slowed and settled. 
The very first rocks were born.

Deep inside Earth, heat still flowed.
Rock melted into glowing liquid called magma.

When magma pushed upward and cooled slowly underground ,it hardened into rock.
When magma burst onto the surface as lava and cooled quickly in the open air, it hardened there, too.

These were the first kind of rock:
igneous—rocks born from fire.

As time passed, wind began to blow. 
Rain began to fall.
Ice cracked stone apart.
Mountains wore down, grain by grain.

Tiny pieces of rock: things like sand, silt, and clay
Were carried by rivers, settled in lakes, and spread across the land.
Layer stacked upon layer.
The weight pressed down.
Water seeped through. The pieces stuck together.
These became sedimentary rocks—rocks made from pieces of other rocks
Holding stories of ancient rivers, deserts, and seas.

Deep underground, nothing stayed the same forever.
Heat rose. Pressure squeezed.
Rocks bent without breaking. Minerals shifted and rearranged.
Without melting,old rocks transformed into something new.
These were metamorphic rocks—rocks changed by heat and pressure,
They were shaped by Earth’s slow strength.

Fire-born rocks.
Layered rocks.
Changed rocks.
Three kinds, woven together in a great cycle.

Igneous rocks could break apart and become sediment.
Sedimentary rocks could sink deepand be transformed.
Metamorphic rocks could meltand begin again.

The ground beneath your feet is not still.
It is a story written in stone: of fire, water, time, and change
A story Earth has been telling for billions of years.
