Hydrothermal Vents occur along divergent plate boundaries on the ocean floor. Hydrothermal vent systems give off plumes of hot, mineral-laden water with temperatures as high as 350 degrees Celcius. The water is ejected through a spout known as black smokers. Metal-rich minerals precipitate out of the circling sea water and forms ores of copper, zinc and iron.
Theater
The presentation of written word, known as "theater," began in Athens and diffused to other parts of the ancient Greek empire.
Government
In 508 B.C. it also gave birth to the world's first democracy. Democracy is a system of government in which citizens elect representatives to advocate for them in the government.
Architecture and art- During the Classical and Hellenistic periods of Greek art, the ancient Greeks idolized the human form. During this time, advances in sculpting and painting techniques were made that would influence the Italian Renaissance centuries later. Once classical Greek art was rediscovered, Italian artists began depicting the beauty of the human body as the Greeks once did. Along with modern religion themes of the time, Italian painters also painted scenes of popular Greek myths and stories.
Answer:the environmental factor that influences the amount of sunlight that reaches the underwater plants and animals are abiotic factors. Aquatic biomes are influenced by a series of abiotic factors. However, these factors differ since water has different physical and chemical properties than does air. Even if the water in a pond or other body of water is perfectly clear (there are no suspended particles), water, on its own, absorbs light. As one descends into a deep body of water, there will eventually be a depth which the sunlight cannot reach. While there are some abiotic and biotic factors in a terrestrial ecosystem that might obscure light (such as fog, dust, or insect swarms), usually these are not permanent features of the environment.
