What causes waves?
Wind’s energy
What causes tides?
The gravitational pull of the moon
What causes surface currents? What causes deep water currents?
Surface currents are caused by: the wind and earth’s rotation Deep water currents are caused by: temperature and salinity changes
Where can tides be seen and why?
At the shore because the land is not moving so you can see the water move in and out.

What is the ocean floor like?

How much salt is in something

Why is ocean water more dense than fresh water? What does that allow you to do in an ocean that you cannot do in a lake?

What do phytoplankton produce?
5o% of the world’s oxygen
How do scientists know what the ocean floor looks like?
They use sonar
What chemicals run off from farms into the ocean?
Fertilizers and pesticides
How can polluting the ocean affect people?
If the fish get sick and then we eat them, then we can get sick. If the plankton die, then ½ of our oxygen is gone.
Why do big cities develop along the coasts?
People use ships to carry and receive products from all over the world.
