Most common currents that you see such as rainwater moving down the streets are currents caused by gravity(the force of an object upon earth). Ocean currents are driven by the gravitational attraction(an object that is attracted by one or two large forces) of the sun and moon of the earth's ocean. Ocean currents are driven by many factors such as wind, thermohaline circulation. Ocean currents are most commonly measured in meters per second or in knots. Thermohaline circulation is a process caused by density differences in water due to temperature and salinity(the amount of salt in the ocean) in different parts of the ocean.

Tidal currents occur in conjunction with the rise and fall of the tide  The vertical motion of the tides near the shore causes the water to move horizontally, creating currents. When a tidal current moves toward the land and away from the sea, it floods. When it moves toward the sea away from the land it ebbs.

* Tides: The rising and falling of sea level
* Tidal currents: they are the only type of current that are affected by the interactions of the sun, moon, and earth.
* Spring currents: Tidal currents occur when the moon is full and very strong.
* Neap currents: occurs the moon is at its first or third quarter and the tide has week velocity.

Summary- Tidal currents occur in conjunction with the rise and fall of the tide.When the vertical motion of tides get closer to shore it causes water to move horizontal making currents. When tidal currents move closer to land  and away for the sea it floods. When it moves closer to seas and away from land it ebbs. The Tidal Currents that ebbs and flood in opposite direction is called rectilinear or reversing currents.]]> 2018-02-20 19:14:48 UTC https://padlet.com/srsimmons/2p9inu9zh0p3/wish/233463867 Tidal Currents 1- Jovanna, Seraj https://padlet.com/srsimmons/2p9inu9zh0p3/wish/233464171 Tidal currents occur in conjunction with the rise and fall of the tide.

- Thermohaline circulation
 A process driven by density differences in water due to temperature and salinity in different parts of the ocean

- Salinity
The concentration of dissolved salts in water

- Gravitational attraction
A factor in Oceanic Currents and making the rise and fall of the sun and moon on Earth's oceans 

- Tidal currents
Tides create a current in the ocean, near the shore, in bays, and estuaries along the coast. Only type of currents that change in a very regular pattern and can be predicted for future dates. 


Summary
 Current describes the motion of the water when associated with water. Oceanic currents are driven by several different factors such as gravitational attraction, Thermohaline circulation, and the wind. The speed and direction of currents are able to be measured. Winds drive currents near coastal areas on a localized scale, and in the open ocean on a global scale. Currents driven by thermohaline circulation occur at both deep and shallow ocean levels and move much slower than tidal or surface currents.

  The conveyor belt begins on the surface of the ocean near the pole in the North Atlantic. Here, the water is chilled by arctic temperatures. It also gets saltier because when sea ice forms, the salt does not freeze and is left behind in the surrounding water. The cold water is now more dense, due to the added salts, and sinks toward the ocean bottom. Surface water moves in to replace the sinking water, thus creating a current . Thus, the conveyor belt gets "recharged." As it moves around Antarctica, two sections split off the conveyor and turn northward. One section moves into the Indian Ocean, the other into the Pacific Ocean.

recharge - re do, reapply
conveyor- begins on the surface ]]> 2018-02-20 19:26:52 UTC https://padlet.com/srsimmons/2p9inu9zh0p3/wish/233472756 Coastal Currents- Jovanna, Seraj https://padlet.com/srsimmons/2p9inu9zh0p3/wish/233474505 Waves: Coastal currents are intricately tied to winds, waves, and land formations.
Key Words:
- Breaking Waves: waves that become too steep and unstable
- Large waves: occur only when all three factors combine
Longshore Currents: When a wave reaches a beach or coastline, it releases a burst of energy that generates a current, which runs parallel to the shoreline.
Key Words:
-  Longshore drift: As a sheet of water moves on and off the beach, it can capture and transport beach sediment back out to sea.
Rip Currents: May form around low spots or breaks in sandbars, and also near structures such as jetties and piers.
Key Words:
- Perpendicular: a straight line at a angle of 90 degrees
Upwelling: Winds blowing across the ocean surface often push water away from an area. When this occurs, water rises up from beneath the surface to replace the diverging surface water
Key Words:
- Subsurface water: rises to the surface as a result of upwelling is typically colder, rich in nutrients, and biologically productive. ]]> 2018-02-20 19:29:30 UTC https://padlet.com/srsimmons/2p9inu9zh0p3/wish/233474505 Surface ocean currents - Kada & Christina https://padlet.com/srsimmons/2p9inu9zh0p3/wish/233476601 Vocabulary
+ Coriolis effect - instead of circulating in a straight pattern, the air deflects towards the right i n the northern hemisphere and the left in the southern hemisphere
+  Intertropical Convergence Zone (also called the doldrums) - between 5 degrees North and 5 degrees South latitude, where the winds are calm.
+  gyres -  major spirals of ocean-swirling currents
+  Ekman spiral -   When surface water molecules move by the force of the wind, they, in turn, drag deeper layers of water molecules below them
Summary
If the earth did not rotate the atmosphere would circulate between the poles and equator. Trade winds  meet at the intertropical convergence zone between 5 degrees north and 5 degrees south latitude. Global winds drag on the water surface causing it to move and build up in the direction that the wind is blowing. Deeper layers of water moves slower than the shallower layers. ]]> 2018-02-20 19:33:05 UTC https://padlet.com/srsimmons/2p9inu9zh0p3/wish/233476601 Tidal Currents 2- Kyra, Felipe kyrcro7131 https://padlet.com/srsimmons/2p9inu9zh0p3/wish/233479800 Key Terms

 Rectilinear/Reversing Currents: Tidal currents that ebb and flood in opposite directions

Summary
Tidal currents are the only type of currents that is affected by the interactions between the Earth, sun, and moon. The moon’s force is much greater than that of the sun because it is 389 times closer to the Earth than the sun is. Tidal currents are affected like tides are by the different phases the moon goes through. Tidal currents occur similarly with the rise and fall of the tide. After slack water occurs the currents switch directions and increase their velocity.

 *Thermohaline circulation: Drives a global-scale system of currents called the global conveyor belt.
* Conveyor belt:  may be affected by climate change
*  polar regions:  ocean water gets very cold, forming sea ice.
*global warming: results in increased rainfall in the North Atlantic, and the melting of glaciers and sea ice, the influx of warm freshwater onto the sea surface could block the formation of sea ice, disrupting the sinking of cold, salty water.
Summary:   when sea ice forms, the salt is left behind.  the seawater gets saltier, its density increases, and it begins to sink. Surface water is pulled in to replace the sinking water, which in turn eventually becomes cold and salty enough to sink. Thermohaline circulation drives a global-scale system of currents called the global conveyor belt. The conveyor belt begins on the surface of the ocean close to the pole in the North Atlantic.

Long shore winds: Winds that blow along the shoreline and affect waves and currents

Breaking waves: Waves that become too steep and unstable

Fetch: the distance over water that the wind blows in a single direction

Summary
Coastal currents are twistedly tied to winds, waves and land formations. Long shore lines, wind that blows along the shore can affect the waves and currents. Wind speed, wind duration, and fetch can affect the wave height. If the winds are slow, only small waves are going to happen, despite the wind duration or fetch. Large waves only occur when all three factors (wind duration, wind speed and fetch) come together.

Long shore drift: As this sheet of water moves on and off the beach, it can “capture” and taken back to beach sediment back out to sea.

Sheet formation: water in a long shore current that flows up onto the beach, and back into the ocean

Angle of wave Approach: Waves that arrive in a slight angle

Summary
The speed when waves approach the shore depends on the seafloor, the shoreline features, and the depth of the water. When a wave is moving towards the beach, the wave slows down because of the different segments of the wave hit the shore before others. The result from this, the wave tends the come together and uphold the general shape of the coastline. Waves usually don’t reach the beach perfectly in line to the shoreline. As a wave reaches the beach or coastline, it releases energy that generate the currents, which runs in line the shoreline.

Rip currents:  a localized current that flows away from the shoreline toward the ocean, perpendicular or at an acute angle to the shoreline

Sandbars: a long, narrow sandbank, especially at the mouth of a river

Summary
Rip currents usually reach speeds of 1 to 2 feet per second. Some rip currents have been looked at and have been measured to 8 feet per second, that is faster than an Olympic swimmer. A rip current breaks up not that far from the shore and is not more than 25 meters wide. When long shore currents keep on moving off and on the beach, which is called rip currents can form around low spots or splits in sandbars. ]]> 2018-02-21 19:28:41 UTC https://padlet.com/srsimmons/2p9inu9zh0p3/wish/233946739 What are tides - David and Seth https://padlet.com/srsimmons/2p9inu9zh0p3/wish/233946976 *Tides:  are one of the most reliable phenomena in the world.

Upwelling: Winds blowing across the ocean surface often push water away from an area. When this occurs, water rises up from beneath the surface to replace the diverging surface water

Summary
When winds blow across the ocean surface, water gets pushed away from an area and subsurface water rises up to take the place of the diverging surface water, this is when an upwelling occurs. Upwellings happen in the ocean and along the coastline. Subsurface water that rises to the surface, this upwelling is rich in nutrients, and very productive. A good fishing spot is where there is an upwelling, because of the nutrients the fish will be there.

Coriolis effect: when going left will go to the right, when going right will go to the left.

Poles: on either side of the earth north & south

Equator: Low pressure area

Summary
Coastal currents get affected by local winds. Surface ocean currents, that occur at the open ocean, are leaded by the global wind system. If the Earth didn’t rotate and stayed still, the atmosphere would circulate between the poles and the equator in a back and forth pattern. The the Earth rotates circulating air is punctured. Instead of circulating in a straight pattern, the air is void.

Trade winds:  prevailing winds from north and southern hemisphere

summary 
In the Northern Hemisphere, warm air that is around the equator rises and head towards the north pole. When air moves away from the equator, the Coriolis effect let it out to the right. In the Southern Hemisphere, winds blow from the southeast in the direction of the northwest and go down near 30 degrees South latitude. Trade winds are known as prevailing winds. The air that doesn’t descend at the 30 degree south or north continues toward the poles.

Summary
The Ekman spiral is named after a Swedish scientist names Vang Walfrid Ekman. He first theorized the Ekman spiral in 1902, which is a consequence of the Coriolis effect. When surface water is forced by the wind, they change and drag deeper layers of water molecules. Each water molecule is moved by friction from the shallow water. Like the surface water, the deeper the water is deflated by the Coriolis effect.

Long-period waves: waves that move through the oceans in response to the forces exerted by the moon and sun

Tidal current: A horizontal movement of water often accompanying the rising and falling of the tide.

Summary
Tides are one of the most reliable phenomena in the world. Tides are long period waves moving through oceans. This is a response to the forces of exerted by the moon and the sun.  They progress towards coastlines and appear as a regular rise and fall of the sea surface. Depending on the location tides height can create high tides.
