The ocean covers more than half
of the surface of our planet, and it The Sunlight Zone
is very deep. It is made up of ive
di ferent zones, and the names
of these zones tell us how much
sunlight reaches those areas. The Twilight Zone
When you travel deeper into the ,
ocean, it gets colder and darker,
and there is less oxygen. For this
reason, not many sea creatures The Midnight Zone
can live there. Di ferent sea ,
creatures live in each zone; some
of them look unusual, but their
appearance helps them deal with The Abyssal Zone
the di icult conditions. Many ,
of them travel from one zone to
another to ind food. The Hadal Zone
