7.1 Ocean Dynamics

Front

What is ocean acidification?

Back

Ocean acidification refers to the process by which the ocean becomes more acidic due to the absorption of carbon dioxide (CO2) from the atmosphere, primarily from the burning of fossil fuels.

Front

What causes ocean acidification?

Back

Ocean acidification is primarily caused by carbon dioxide released from combustion/burning fossil fuels.

Front

Why is upwelling important in ocean dynamics?

Back

Upwelling is important because it brings nutrient-rich water from the bottom of the ocean to the surface, supporting marine life.

Front

What role do ocean currents play in the ocean?

Back

Ocean currents are primarily responsible for the distribution of heat in the ocean, affecting climate and weather patterns.

Front

How does increased salinity affect ocean water density?

Back

Increased salinity increases the density of ocean water, making it heavier.

Front

What are spring tides?

Back

Spring tides occur when the Earth, moon, and sun are aligned, resulting in higher high tides and lower low tides.

Front

What are neap tides?

Back

Neap tides occur when the moon is in its first or third quarter phases, resulting in lower high tides and higher low tides.

Front

What is the difference between spring and neap tides?

Back

The main difference is that spring tides occur when the Earth and sun are aligned with the moon, while neap tides occur when the moon is at a right angle to the Earth-sun line.

Front

What is the effect of ocean currents on marine ecosystems?

Back

Ocean currents help distribute nutrients and heat, which are essential for the survival of marine ecosystems.

Front

What is the significance of nutrient-rich water in the ocean?

Back

Nutrient-rich water supports the growth of phytoplankton, which forms the base of the marine food web.
