Did you know?

• 70 of our planet is ocean but as little as 1 is
  protected.
• All the continents were once a great big
  continent called Pangaea
• North America and South America are moving away
  from Eurasia and Africa because of ocean floor
  spreading.

• As little as 10 of the sea floor is known or
  explored.
• The youngest rocks found on the sea floor are
  found in the middle of the ocean because that is
  where new sea floor is added.

Sea-floor Spreading
Sea floor spreading occurs when the ocean floor
is extended as two plates spread apart. Magma
seeps from the opening forming an oceanic ridge
as the magma cools.

The mid Atlantic ridge is really an underwater
mountain range!
Do you wonder what the ocean would look like
without any water? It is not flat like a desert.
It is full of mountains, valleys, volcanoes, and
plains just like on dry land.

We all need to remember that we each are part of
this planet. Just because we dont see the ocean
floor doesnt mean its not there. That tin can
you throw away may be on the ocean floor one
dayMankind has probably done more damage to
the Earth in the 20th century than in all of
previous human history.(Jacques Yves Cousteau)
