Final answer:
Earth scientists study a variety of subjects including oceans, planets, weather, and glaciers, all of which are integral to understanding Earth's systems. This multidisciplinary field encompasses both the physical properties and processes of our planet and extends to the study of other celestial bodies.
Step-by-step explanation:
Earth scientists may study various subjects that encompass diverse aspects of the Earth's physical properties and processes. Four subjects that earth scientists might focus on include:
- Oceans: This includes the study of marine ecosystems, ocean circulation, and coastal geography, among other topics.
- Planets: Planetary geology is a field that extends beyond Earth, examining the geology of other planets and celestial bodies in our solar system.
- Weather: This pertains to climatology and the study of atmospheric conditions that define the short-term state of the atmosphere.
- Glaciers: Glaciology is the branch that specializes in the study of glaciers and ice ages, which covers both current and historical periods of cooling.
All of these subjects are integral to understanding the planet's past, present, and potential future, making Earth science a multidisciplinary and dynamic field.
