2,3,4 correct.
Question 1 makes no sense, are you certain you typed it correctly?
Question One does not make sense.
1. Coral reefs are only found in the euphotic zone, which is the shallowest zone of the ocean. The euphotic zone is the region where sunlight can penetrate and reach the photosynthetic organisms, such as the algae that live in the coral reefs. These photosynthetic organisms depend on sunlight for energy, and they are essential for the survival of the coral reefs. Additionally, the shallow waters in the euphotic zone provide the right conditions for the growth and development of the coral reefs.
To find the answer to this question, you can research the characteristics of coral reefs and their ecological requirements. Understanding the relationship between sunlight, photosynthesis, and the distribution of coral reefs will help you understand why they are only found in the euphotic zone.
2. The greatest challenge for human exploration of the Mariana Trench is the extreme pressure from the water pushing down. The Mariana Trench is the deepest part of the ocean, reaching depths of about 11 kilometers (6.8 miles). At such depths, the pressure is incredibly intense, and it can reach over 1000 times the atmospheric pressure at the surface. This pressure poses a significant risk to any human exploration or equipment that ventures into the trench.
To find the answer to this question, you can investigate the characteristics of the Mariana Trench, including its depth, pressure, and the challenges associated with exploring such extreme environments.
3. Dissolved carbon dioxide affects the ocean by making it more acidic. When carbon dioxide from the atmosphere dissolves in seawater, it undergoes a series of chemical reactions that lead to the formation of carbonic acid. This acidification process lowers the pH of the ocean, making it more acidic. Increased acidity can have detrimental effects on marine organisms, such as corals, shellfish, and other organisms that rely on calcium carbonate for skeletal structures.
To find the answer to this question, you can study the process of ocean acidification and its impact on marine ecosystems. Understanding the chemistry of dissolved carbon dioxide and its effects on seawater pH will help you grasp the role it plays in altering the acidity of the ocean.
4. Ocean temperatures are related to the weather because heat in the atmosphere can result in stronger hurricanes. Warmer ocean temperatures provide more energy to hurricanes, allowing them to intensify and become more powerful. This is because hurricanes thrive on warm ocean waters, which provide the necessary heat and moisture for their formation and development.
To find the answer to this question, you can research the relationship between ocean temperatures and weather patterns, particularly the impact of warm ocean waters on the formation and intensity of hurricanes. Understanding the concept of thermal energy transfer between the ocean and the atmosphere will help you grasp the connection between ocean temperatures and weather conditions.
