Fossil fuels like oil and coal are made when
dead plants and animals are under high heat and
pressure for millions of years.The kind of heat
and pressure it takes are deep underground.
Sometimes fossil fuels come to the surface on
their own, but most of the time we have to drill
or dig into the ground to get them. People can
drill into the sand and rock that makes up the
bottom of the sea in order to get oil and natural
Drilling under the sea bed is harder
to do because the drilling rigs have to be on
platforms that either float in the water or stand
on the ocean floor. These platforms are huge and
expensive. A drilling rig can cost $500 million.
It can be dangerous for the people on the rig and
to the living things around the rigs.
gas and oil may be under enough pressure that they
will come to the surface on their own. If not,
the drillers can force sea water down the hole.
Water and gas are lighter than water, so the will
come to the top.

there in order to keep you safe and comfortable?
