Ean Transport and Ocean Dynamics

The video explains the Ean transport phenomena, where wind blowing parallel to the coastline causes water to move perpendicularly, creating a spiral effect known as the Ean spiral. This movement is influenced by the Coriolis force, causing each water layer to move at a 45-degree angle to the one above it. The video also discusses Egman's observations in Greenland, which led to the development of Ean Theory. The effects of Ean transport include upwelling and downwelling, which impact nutrient distribution and fisheries. The video concludes with a discussion on global ocean currents and a call to action for viewers.

What is the primary direction of net water transport in relation to the wind according to the Ean transport theory?

• At a 30° angle to the wind

• Parallel to the wind

• Perpendicular to the wind

• Opposite to the wind

What observation led Egman to develop the Ean transport theory?

• Icebergs moving parallel to the wind

• Icebergs remaining stationary despite the wind

• Icebergs moving at a 30° to 40° angle to the wind

• Icebergs moving faster than the wind

How does friction affect the movement of water layers under the influence of wind?

• It has no effect on water movement

• It causes each subsequent layer to move slower and cover less distance

• It causes each subsequent layer to move faster

• It causes all layers to move at the same speed

What angle does each water layer move in relation to the layer above it due to the Coriolis force?

• 60°

• 45°

• 30°

• 90°

What is the Ean spiral?

• A pattern of water movement where all layers move in the same direction

• A spiral of wind currents in the atmosphere

• A pattern of water movement where each layer moves at a 45° angle to the one above

• A spiral of ocean currents moving in opposite directions

What is upwelling and why is it important?

• The movement of water towards the coast, important for erosion

• The rise of deep, nutrient-rich water to the surface, supporting marine life

• The sinking of surface water, reducing nutrient availability

• The horizontal movement of water, affecting weather patterns

How does Ean transport affect nutrient distribution in the ocean?

• It evenly distributes nutrients throughout the ocean

• It prevents nutrient movement in the ocean

• It brings nutrients from the ocean floor to the surface

• It depletes nutrients from the ocean surface

What is the effect of Ean transport on oceanic gyres?

• It has no effect on gyres

• It causes gyres to move in a straight line

• It causes gyres to rotate in the opposite direction

• It leads to the accumulation of water in the center of gyres

What happens during downwelling?

• Water remains stationary, with no vertical movement

• Surface water is pushed downwards, reducing surface nutrients

• Deep water rises to the surface, increasing surface nutrients

• Water moves horizontally along the coast

How does the Ean transport phenomenon contribute to fisheries?

• By reducing the availability of plankton

• By causing fish to migrate away from coasts

• By creating nutrient-rich areas that support marine life

• By depleting fish populations
