Currents | Flowing streams of water that move continuously throughout he ocean in a specific direction |
Surface Currents | These currents are caused by the movement of the Earth and by the force and direction of the wind |
Warm Surface Currents | These currents are driven by Earth's rotation from the tropics to higher latitudes |
Cold Surface Currents | These currents are driven by Earth's rotation from the polar latitudes toward the equator |
Tides | The regular rise and fall of waters in oceans and seas; they are caused by the pull on the Moon's gravity on Earth |
Natural Resources | Water, Oil and Wood |
Pollution | Examples include careless dumping of trash on land; oil spills in oceans and smoke and fumes from burning fuels that ruins the air |
