Ocean Dynamics and Coriolis Effect

The video explains upwelling in the ocean, focusing on the Coriolis Effect and the Ekman Spiral. It describes how the Coriolis Effect causes objects to veer due to Earth's rotation, leading to the formation of the Ekman Spiral in ocean currents. Upwelling is then explained as a process where deep, nutrient-rich water rises to the surface, driven by wind and the Coriolis Effect, enhancing ocean productivity.

What is the Coriolis Effect primarily responsible for?

• Changing the color of ocean water

• Causing objects to veer right in the northern hemisphere and left in the southern hemisphere

• Increasing the temperature of ocean water

• Decreasing the salinity of ocean water

How does the Coriolis Effect influence wind movement?

• It causes wind to change direction due to Earth's rotation

• It stops wind from moving

• It makes wind move in a straight line

• It increases wind speed

How does the Coriolis Effect impact the direction of wind in the northern hemisphere?

• It causes wind to veer left

• It causes wind to veer right

• It causes wind to stop

• It has no effect on wind direction

What analogy is used to explain the Coriolis Effect?

• Drawing a straight line on a rotating sheet of paper

• Swimming in a pool

• Walking on a treadmill

• Throwing a ball in the air

What is the Ekman Spiral?

• A type of seaweed

• A spiral pattern of water movement caused by wind and the Coriolis Effect

• A method of measuring ocean depth

• A type of ocean current

What happens to water movement beneath the surface due to the Ekman Spiral?

• It moves in a spiral pattern

• It remains stationary

• It moves in the opposite direction of the wind

• It moves in a straight line

In the context of ocean dynamics, what does upwelling refer to?

• The rising of warm water to the surface

• The sinking of cold water to the bottom

• The upward movement of dense, nutrient-rich water from the ocean floor

• The horizontal movement of water across the ocean

What role does the Ekman Spiral play in upwelling?

• It prevents upwelling from occurring

• It helps in the upward movement of water

• It causes water to sink

• It has no role in upwelling

Why is upwelling important for ocean productivity?

• It decreases the temperature of the ocean

• It increases the salinity of the ocean

• It brings nutrients to the surface, supporting marine life

• It causes ocean currents to stop

What is the result of upwelling on marine ecosystems?

• Decreased ocean salinity

• Increased ocean temperature

• Increased nutrient availability and productivity

• Decreased marine life
