What is a coral reef?
  • A coral reef is a reef that is composed mainly of
    coral and other organic matter of which parts
    have solidified into limestone. The resulting
    structure provides a critical habitat for a wide
    variety of fish and marine invertebrates. Coral
    reefs also protect shores against erosion by
    causing large waves to break and lose some of
    their force before reaching land.

3
Which is the biggest?
  • The Great Barrier Reef off the northeastern coast
    of Australia extends for some 2,000 km (1,240
    mi), making it the world's largest coral reef.

Why are we worried?
  • A lot of organizations are worried about coral
    reefs around the world for many reasons! One is
    because of oil spills that can wipe out a whole
    reef!
  • Coastal development
  • Overfishing
  • Global climate change.

Is there more than one?
  • There are actually three different types of
    reefs!
  • Barrier reefs- Barrier reefs grow parallel to
    the shoreline. They are separated by water from
    the mainland. Fringing reefs- Fringing reefs are
    permanent with the landmass
  • Atolls- Atolls are islands. These are made of
    coral surrounding a central lagoon.
