Select all that applySelect all of the effects of increased CO2 accumulation due to human activities.Multiple select question.Ocean water becomes more acidic.Shells of mollusks and exoskeletons of corals dissolve.Ozone levels in the ocean increase and block light for photosynthesis.Harmful UV radiation from the sun reaches deeper ocean zones.

In simple terms, explain the effect that increased atmospheric carbon dioxide has on the ocean.

An increase in the amount of carbon dioxide in the atmosphere can cause atmospheric temperatures to increase.  Which statement explains how this could affect the ocean as a carbon sink?ResponsesLess atmospheric carbon dioxide would be available to phytoplankton.Less atmospheric carbon dioxide would be available to phytoplankton.Dissolved carbon dioxide gas in the ocean would increase because surface winds would cause a deeper circulation pattern, making more room for the gas. Dissolved carbon dioxide gas in the ocean would increase because surface winds would cause a deeper circulation pattern, making more room for the gas. Less carbon dioxide gas would be contained in the ocean because increasing precipitation would dilute the carbon entering the ocean. Less carbon dioxide gas would be contained in the ocean because increasing precipitation would dilute the carbon entering the ocean. Less carbon dioxide would be dissolved in the ocean because increasing atmospheric temperatures would cause ocean temperatures to increase.

1. (8 pts) Take a breath and exhale. Describe how the CO2 you exhaled gets into the ocean, is used by phytoplankton to make sugars, is used by phytoplankton to make shells, and can eventually wind up on the seafloor.2. (4 pts) Consider what you learned in the Ocean Acidification Lab: An increase in atmospheric carbon dioxide is causing an increase in what ion in the world’s oceans? How is this affecting shell building organisms such as phytoplankton?

What process in the carbon cycle has increased carbon dioxide in the atmosphere and in the ocean, causing damage to ecosystems?Multiple ChoiceCompressionDecompositionPhotosynthesisBurning fossil fuels

Which of the following is UNLIKELY to be a consequence of the build-up of carbon dioxide in the upper atmosphere that is being caused by human activities?AGlaciers and polar ice caps meltingBGradual breakdown of ozone layer in the upper atmosphereCWeather patterns becoming more severeDGlobal temperatures increasing
