Marine geology is a subset of geology focused specifically on the solid Earth beneath oceans (rocks, sediments, tectonics). Oceanography is a broader interdisciplinary science covering the physical, chemical, biological, and geological aspects of the entire ocean.
They use tools like sonar for seafloor mapping, coring devices to collect sediment and rock samples, remotely operated vehicles (ROVs), seismic reflection profilers to image subsurface layers, and various laboratory instruments for sample analysis.
No, it encompasses all submarine environments, including continental shelves, slopes, rises, abyssal plains, mid-ocean ridges, and even coastal and estuarine geology.
It is crucial for understanding Earth's history (climate records in sediments), locating natural resources (oil, gas, minerals), assessing geohazards (submarine landslides, earthquakes), and planning submarine infrastructure (cables, pipelines).
