• Summer

• Fall

• Winter

What is upwelling?

• Movement of warmer, nutrient-poor water to the surface.

• Movement of deeper, colder water to the surface, bringing nutrients up.

• Replacement of surface water with water from the bottom.

• Increase in water temperature due to sunlight.

What effect does upwelling have on biodiversity?

• Decreases biodiversity due to nutrient depletion.

• Increases biodiversity due to increased producers.

• Has no effect on biodiversity.

• Decreases biodiversity due to increased temperature.

What is turnover in the context of lakes and ponds?

• Movement of surface water to the bottom.

• Replacement of surface waters with water from the bottom.

• Evaporation of water from the surface.

• Increase in water temperature.

How does upwelling affect water quality and nutrients?

• Decreases water quality and nutrients.

• Has no effect on water quality and nutrients.

• Improves water quality and nutrients.

• Decreases nutrients but improves water quality.

What is eutrophication in relation to upwelling?

• Decrease in algal growth due to nutrient loss.

• Increase in algal growth creating 'dead zones.'

• Stabilization of algal growth.

• Decrease in water temperature.

What is the role of upwelling in the Carbon Cycle?

• It releases carbon into the atmosphere as a gas.

• It absorbs carbon from the atmosphere.

• It prevents carbon from reaching the surface.

• It converts carbon into solid form.

How does upwelling affect the Nitrogen Cycle?

• It reduces nitrogen levels in the ocean.

• It brings in excess nitrogen, contributing to eutrophication.

• It stabilizes nitrogen levels in the atmosphere.

• It converts nitrogen into oxygen.

What is the effect of upwelling on the Water Cycle?

• It evaporates water from the ocean surface.

• It mixes water temperatures and nutrients from deep to surface layers.

• It freezes water at the ocean surface.

• It prevents water from circulating.
