Tides, Waves, And Currents

Front 1

Neap Tide

Back 1

A tide with the least difference between low and high tide that occurs when the sun, moon pull at right angles to each other

Front 2

Spring Tide

Back 2

A tide with the greatest difference between high and low tide that occurs when the Earth, Sun, and moon are in a line

Front 3

Tide

Back 3

The daily rise and fall on shores caused mostly by the moon's gravity

Front 4

Gravitational Pull

Back 4

The force or attraction between the Earth, Sun, and the Moon that keeps Earth rotating on it's axis

Front 5

Tidal Bulge

Back 5

Results when the moon pulls Earth's waters , the ocean beneath the moon that keep the earth rotating on it's axis

Front 6

What causes tides?

Back 6

Gravity from the moon

Front 7

Current

Back 7

Like rivers that flow through the ocean

Front 8

Surface current

Back 8

Large circular streams kept in motion by prevailing winds and rotation of the Earth

Front 9

Subsurface current

Back 9

Generally travels at a much slower speed than surface currents and a substrate current is driven by daily density of water

Front 10

Gulf Stream

Back 10

Is an exMple of a current in the North Atlantic

Front 11

Kuroshio

Back 11

Is an example of a current in the North Pacific

Front 12

Upwelling

Back 12

Is a current created near the shore due to convection and causes deep cold currents to rise to the surface along some western coastline

Front 13

What causes currents?

Back 13

Rotation of Earth on it's axis and gravitational pull

Front 14

Wave

Back 14

Is the way in which energy travels from one place to another

Front 15

Crest

Back 15

The highest point the wave reaches

Front 16

Trough

Back 16

Lowest point the wave reaches

Front 17

Wavelength

Back 17

Is the distance from one crest to the next crest

Front 18

Breaker

Back 18

Is a wave whose crest falls forward and crashes into the trough

Front 19

Amplitude

Back 19

Is the measurement from the middle of the wave to the trough or crest

Front 20

What causes waves?

Back 20

Wind
Gravitational pull
Earthquakes
Landslides
Under water volcanos
