Answer:
Oceanography- “scientists study the physical and chemical properties of sea waters” and “scientists observe changes to marine life and aquatic ecosystems”.
Geology- “scientists examine the type of rocks found on earths surface” and “scientists learn about Earths landforms using historical records”.
Step-by-step explanation:
The definition of oceanography is “the branch of science that deals with the physical and biological properties and phenomena of the sea.” So the options involving the sea will go into the oceanography category.
The definition of geology is “the science that deals with the earth's physical structure and substance, its history, and the processes that act on it.” So the options involving Earth and the land will go into the geology category.
