B. oceans
An earth scientist studies various aspects of the Earth, which can include the oceans, atmosphere, geology, and other natural processes. While they may touch on related topics like farming methods or plant cells in environmental studies, their primary focus is on Earth's physical characteristics and processes.

C. radioactive dating
Radioactive dating, particularly through methods like radiometric dating, has provided earth scientists with precise evidence to determine the age of the Earth. By measuring the decay of radioactive isotopes in rocks and minerals, scientists can estimate the time that has passed since those materials formed, helping to establish the Earth's age with significant accuracy.

C. making hypotheses
Making hypotheses is a fundamental part of the scientific method. It involves formulating testable predictions or explanations based on observations, which can then be tested through experimentation and analysis. This step is crucial for advancing scientific knowledge.

A. to predict planetary changes
Studying earth science is essential for understanding the Earth’s processes, including geological, atmospheric, and oceanic changes. This knowledge allows scientists to predict changes in the environment, such as natural disasters or climate change, which is critical for preparedness and mitigation efforts. While the other options may relate to broader scientific knowledge, they are not the primary focus of earth science.

D. Scientists now think the earth is much older.
Since 1650, advances in scientific understanding, particularly through techniques like radioactive dating, have led scientists to estimate that the Earth is approximately 4.5 billion years old, which is significantly older than the 6,000-year estimate made in 1650.
