What are ocean motions?
The answer is ocean currents. Ocean currents are continuous movements of water in the ocean that follow set paths, kind of like rivers in the ocean.
How do particles move in an ocean wave quizlet?
The nearly friction free transfer energy from water particles to water particles in these circular paths, or orbits, transmits wave energy across the ocean surface and causes the wave form to move. This kind of wave is the orbital wave, a wave in which particles of water move in closed circles as the wave passes.
When denser seawater sinks under less dense seawater a current is formed?
Cards
| Term Salinity | Definition is a measure of the amount of solids, or salts, dissolved in seawater |
|---|---|
| Term density current | Definition forms when more dense seawater sinks beneath less dense seawater. |
| Term upwelling | Definition is a current in the ocean that brings deep, cold water to the ocean surface. |
What has the greatest influence over the creation of waves?
Waves are moving energy and most ocean waves are initiated by the wind. The three factors that influence the height, wavelength, and period of a wave are (1) wind speed, (2) length of time the wind has blown, and (3) fetch, the distance that the wind has traveled across open water.
What are the three motions of the ocean?
A Waves.
Why do the oceans motion?
More salt makes water heavier and therefore denser. These two factors, temperature and salinity, are the main driving forces behind Earth’s ocean conveyor belt, which is a huge water circulation system in the deep ocean that moves water around the globe.
How do particles move in an ocean wave?
Water waves are an example of waves that involve a combination of both longitudinal and transverse motions. As a wave travels through the waver, the particles travel in clockwise circles. The radius of the circles decreases as the depth into the water increases.
What is the typical particle motion in an ocean wave?
Instead, the water particles move in circular orbits, with the size of the orbit equal to the wave height (Figure 10.1. 3). This orbital motion occurs because water waves contain components of both longitudinal (side to side) and transverse (up and down) waves, leading to circular motion.
What causes water to become denser when it is carried to the polls by surface currents?
What causes water to become denser when it is carried to the poles by surface currents? … Wind direction the spin of Earth and differences in temperature contribute to currents.
How does the rotation of the earth influence the direction of the ocean currents?
Our planet’s rotation produces a force on all bodies moving relative to theEarth. Due to Earth’s approximately spherical shape, this force is greatest at the poles and least at the Equator. The force, called the “Coriolis effect,” causes the direction of winds and ocean currents to be deflected.
What factors affect the movement of ocean water?
Temperature, winds, gravitational pull of the sun, the earth and the moon, warm and cold currents are the factors that effects the movement of ocean water.
Which factors play a role in creating ocean waves?
Waves are most commonly caused by wind. Wind-driven waves, or surface waves, are created by the friction between wind and surface water. As wind blows across the surface of the ocean or a lake, the continual disturbance creates a wave crest.
What do you call ocean motion?
The term “current” describes the motion of the ocean. Ocean currents are driven by wind, water density differences, and tides.
What is the movement of ocean waves called?
A large movement of water in one general direction is a current. Currents can be temporary or long-lasting. They can be near the surface or in the deep ocean.
Which are the three main types of movements that occur in oceans?
A Waves.
How does ocean water move globally?
The ocean is not a still body of water. There is constant motion in the ocean in the form of a global ocean conveyor belt. This motion is caused by a combination of thermohaline currents (thermo = temperature; haline = salinity) in the deep ocean and wind-driven currents on the surface.
Why does water in the ocean move?
What makes ocean currents flow? Tides contribute to coastal currents that travel short distances. Major surface ocean currents in the open ocean, however, are set in motion by the wind, which drags on the surface of the water as it blows. The water starts flowing in the same direction as the wind.
What is the movement of the waves?
Wave motion is the transfer of energy and momentum from one point of the medium to another point of the medium without actual transport of matter between two points.
What sort of motion happens in water?
This orbital motion occurs because water waves contain components of both longitudinal (side to side) and transverse (up and down) waves, leading to circular motion. As a wave passes, water moves forwards and up over the wave crests , then down and backwards into the troughs , so there is little horizontal movement.
What are the characteristics of ocean waves?
Wave Characteristics
- Crest = Highest point of the wave.
- Trough = Lowest point of the wave.
- Wavelength = Distance from one crest/trough to the next (m)
- Wave Height = Height from trough to crest (m)
- Wave steepness = ratio of wave height to wavelength.
