Marine geology is the study of the ocean floor and the geological processes that shape it. This field examines features like submarine volcanoes, ocean trenches, and continental shelves. By understanding these structures, scientists can learn about Earth's history, including how continents have moved and how ocean currents have changed over time. Researchers in marine geology also investigate sediment layers and fossils found on the ocean floor. These sediments can reveal information about past climates and ecosystems. By studying these materials, scientists can better understand the impact of climate change and human activities on marine environments, helping to protect our oceans for future generations.
