Do rocks grow
.-. this is what the human race has come to..
Crystals can grow they are a type of rock :)
Most rocks erode into sand or dust.
No, they come from the ocean though. There's a crack deep in the ocean with hot magma or lava and it pushes up onto the ocean floor. The process continues and eventually, the rocks reach the surface. The size varies
Not bigger but smaller yes they can error
newbuddah13 and batgirl3737 are right. Most rocks get smaller over time. They are where sand and inorganic soil matter come from.
Some can get larger, sedimentary rocks can accumulate layers. sometimes if you put them in lemon juice or vinegar you can see layers.
