CURRENTS
- Currents are influences by weather, the Earth's rotation, and the position of the continents
- two types of currents are ocean and surface currents. An ocean current is the movement of ocean water that goes in a pattern. A surface current is the same but with a horizontal movement.
- There is also deep currents which are like surface currents but near the bottom of the ocean.
- Then there is the Coriolis effect that helps make these currents. The definition is(from earth science book) : the apparent curving of the path due of an otherwise straight path due to the Earth's rotation.
- CURRENTS AND CLIMATE
- Suface currents affect climate ALOT, in many parts of the world.
- Warm water currents make the surrounding air warmer, while cold currents make it colder.
- Upwelling: process where cold nutrient rich water comes to the surface - Earth science book page 423
- Every two to twelve years El Nino occurs. El Nino is a change in the water temperature in the Pacific Ocean. (earth science book pg 424)
- Sometimes after El Nino, La Nina occurs. La Nina is like the opposite of El Nino and only occurs in the eastern Pacific Ocean and the waters become cold.

- Waves are made of two parts, the crest and the trough, this is how you measure wave length.
- Waves form by gravity of the move and energy from the water.
- There are several different types of waves such as deep-water waves, shallow-water waves, and breakers.
- undertow is pretty much what it sounds like. It is a subsurface current that is near shore and that pulls objects out to sea.
- Longshore current is what it sounds like also. It is a water current that travels near and parallel to the shoreline, so it is literally a LONG-shore current.
- Have you ever walked on the beach and saw those BIG white waves in the ocean? Well those are whitecaps. They are the bubbles in the crest of a breaking wave.
- The rolling waves you might see at the shore of the ocean are swells. They are a group of waves that have traveled steadily along the ocean since when they were first created.
- A tsunami is like a white cap just much much larger and much much bigger. They are a giant ocean wave that forms after a volcanic eruption, submarine earthquake, or landslide.
TIDES
- To start off with tides here is the definition. The periodic rise and fall of the water level in the oceans and other large bodies of water.
- The timing of tides depends on the rotation of the earth and the moon's revolution around the Earth.
- There are two different types of tides, spring and neap tides.
- To say what these tides are you have to know what tidal range is. It is the difference in the levels of ocean water at high tide and low tide...................................................................................................................................................................
- Spring tides are tides of increased range and happens two times every month on the new and full moon.
- Neap tides are tides with minimum range and happens at the first and third quarters of the moon.
