22.214.171.124.2.1 Sediment is solid material that is moved and deposited in a new location. Sediment can consist of
rocks and minerals, as well as the remains of plants and animals. It can be as small as a grain of sand
or as large as a boulder. Sediment moves from one place to another through the process of erosion.
126.96.36.199.3 Sedimentary rock
188.8.131.52.3.1 Sedimentary rocks are made when sand, mud and pebbles get laid down in layers. Over time, these
layers are squashed under more and more layers. Eventually, the layers are lithified – turned to rock.
Sedimentary rocks can be formed in deserts , lakes, rivers and seas .

6.1 Hydraulic fracturing, or 'fracking', is a technique used to get a type
of gas found deep underground in shale rock. Shale gas is trapped
inside tiny pockets of rock - which makes it hard to reach.

when fracking is done.
