Text and Images from Slide

Text Box: 3.1 How and where do rocks form?

Bits of shell, calcite and aragonite

But what else can we tell from observing?

The quartz grains are small, and very round

Even the dark grains are round-ish, if small

and the shell fragments, while flat, have rounded edges. What processes are involved? Watch the waves moving the sand
