Oceanic materials refer to the various substances and resources found in the ocean. These include minerals, sediments, and biological materials like coral and seaweed. Oceanic materials play a crucial role in marine ecosystems and can be harvested for various uses, such as construction, pharmaceuticals, and food. Additionally, oceanic materials are essential for understanding Earth's geology and climate. For example, the study of ocean sediments can provide insights into past climate changes. Researchers often explore these materials to develop sustainable practices and protect marine environments, highlighting the importance of preserving our oceans for future generations.
