3. softish, porous or crumbly rock, usually made from compacted grains of mineral material and often containing fossils

Below is a series of steps that produces a sedimentary rock like sandstone, but the steps are in the wrong order.
(1) grains of rock moved by water
(2) water squeezed out and the rock grains stick together
(3) rocks are weathered and eroded
(4) layers of sediment buried and compressed
(5) grains of rock laid down as sediment
