What is ocean acidification?

• Ocean acidification is the process of the ocean becoming less acidic due to the absorption of carbon dioxide from the atmosphere.

• Ocean acidification is the process of the ocean becoming more alkaline due to the absorption of carbon dioxide from the atmosphere.

• Ocean acidification is the process of the ocean becoming more acidic due to the absorption of oxygen from the atmosphere.

• Ocean acidification is the process of the ocean becoming more acidic due to the absorption of carbon dioxide from the atmosphere.

Ethan, Abigail, and James are having a debate about the properties of water. Ethan says water is polar, an excellent solvent, and has high surface tension. Abigail says it's nonpolar, a poor solvent, and has low surface tension. James thinks it's ionic, an average solvent, and has medium surface tension. Who is correct?

• Ethan: polar, excellent solvent, high surface tension

• Abigail: nonpolar, poor solvent, low surface tension

• James: ionic, average solvent, medium surface tension

• None of them

Explain the nitrogen cycle.

• The nitrogen cycle is the process by which oxygen is converted between its various chemical forms in the environment.

• The nitrogen cycle is the process by which carbon dioxide is converted between its various chemical forms in the environment.

• The nitrogen cycle is the process by which water is converted between its various chemical forms in the environment.

• The nitrogen cycle is the process by which nitrogen is converted between its various chemical forms in the environment.

Describe the carbon cycle.

• The carbon cycle is the process by which carbon is exchanged between the atmosphere, land, oceans, and living organisms.

• The carbon cycle is the process by which carbon is exchanged between the atmosphere, land, oceans, and nitrogen.

• The carbon cycle is the process by which carbon is exchanged between the atmosphere, land, oceans, and non-living organisms.

• The carbon cycle is the process by which carbon is exchanged between the atmosphere, land, oceans, and water.

What is coral bleaching?

• Coral bleaching is the process by which corals grow at an accelerated rate due to excess nutrients in the water.

• Coral bleaching is the process by which corals lose their color due to stress caused by changes in environmental conditions such as temperature, light, or nutrients.

• Coral bleaching is the process by which corals become more resistant to changes in environmental conditions.

• Coral bleaching is the process by which corals gain more color due to increased exposure to sunlight.

Abigail, Aiden, and Liam are studying the impact of ocean acidification on marine life for their science project. They are particularly interested in how it affects marine organisms. What conclusion might they reach based on their research?

• They might conclude that ocean acidification only affects large marine animals, not smaller ones.

• They might conclude that ocean acidification has no impact on marine life.

• They might conclude that ocean acidification makes the water more acidic, harming marine organisms' shells, skeletons, growth, and reproduction.

• They might conclude that ocean acidification improves the health and growth of marine organisms.

Samuel, Charlotte, and Kai are working on a science project about the ocean. They are trying to understand what influences the properties of seawater. What are the primary factors they should consider?

• wind speed, humidity, and altitude

• gravity, magnetic field, and sunlight

• temperature, pressure, and the presence of dissolved substances

• pH level, salinity, and color

Nora, Mia, and Evelyn are studying the role of nitrogen in their school garden. What role does nitrogen play in their garden ecosystem?

• Nitrogen is essential for the growth and development of plants and animals in their garden, and it plays a vital role in the nitrogen cycle.

• Nitrogen is only found in the atmosphere

• Nitrogen is harmful to the plants and animals in their garden

• Nitrogen has no role in their garden ecosystem

How does carbon cycle through the environment?

• Carbon cycles through the environment through processes such as transpiration, infiltration, and runoff.

• Carbon cycles through the environment through processes such as evaporation, condensation, and precipitation.

• Carbon cycles through the environment through processes such as photosynthesis, respiration, decomposition, and combustion.

• Carbon cycles through the environment through processes such as erosion, weathering, and sedimentation.

What are the main causes of coral bleaching?

• Changes in water temperature, pollution, overexposure to sunlight, and ocean acidification.

• Excessive fishing, volcanic eruptions, and deforestation

• Alien invasion, supernatural forces, and divine intervention

• Lack of sleep, excessive caffeine intake, and bad luck
