Click on the type of rock you want to start with.
sedimentary
metamorphic
intrusive igneous
extrusive igneous
gneiss
basalt
granite
You are an extrusive igneous Rock
Resulting from the cooling of lava that exited a volcano and small or no crystals formed.
Weathering and erosion

basalt

obsidian
subduction
You subduct above the mantle
You subduct into the mantle
You are an intrusive igneous Rock
Resulting from the cooling of magma under the surface of the Earth and large crystals form.

You are a Sedimentary Rock
Built from layers of sediment that were compacted and cemented together under water.

subduction
You subduct above the mantle
You subduct into the mantle
convergent boundary
Uplift exposes you to weathering and erosion which uses mainly the energy of the sun
Weathering and erosion
Weathering is the breaking down or dissolving of rocks and minerals on the surface of the Earth. Water, ice, acids, salts, plants, animals, and changes in temperature cause weathering.
Erosion happens from the action of wind, water, and glaciers that move the rocks and sediment from one place to another.
How rock metamorphosis works
You are a metamorphic rock
Resulting from the effects of heat from the core and pressure from gravity which occurs far under the surface of the Earth.

gneiss
You subduct above the mantle
You subduct into the mantle
convergent boundary
You are magma
Resulting from the melting effects of heat from the core on the minerals in the mantle.
magma
You come out as lava and cool on the surface
You stay under the surface and cool
Now you are sediment
Resulting from the effects of heat from the sun which causes the weathering and erosion from wind, rain, and waves.
Sediment undergoes compaction and cementation
