Earth science, also known as geoscience, encompasses various subfields such as geology, atmospheric science, meteorology, and oceanography. Geology analyzes materials like rocks and sand, while atmospheric science studies the atmosphere and related factors. Meteorology focuses on climate-related issues, and oceanography studies the planet’s bodies of water, including marine and freshwater habitats. Students learn about the types of water bodies, their salinity, and the organisms that can survive in them.
Earth science is a vast field devoted to the study of the earth and the various factors related to that study. Another name for this field of study is geoscience, made up of several subfields that include subjects such as geology, atmospheric science, and meteorology. It also involves the study of oceanography with the aim of applying the knowledge gained from studying the properties and behavior of the various bodies of water on Earth itself.
One of the areas of study in earth science is geology, a field focused on the analysis of materials such as rocks and sand found in the earth. These materials often contain information capable of telling a story to trained geologists or other professionals. For example, some large rocks contain striations that reveal a wealth of information ranging from the presence of water in deserts at some point in the distant past to other events that may have occurred as a result of climate or the age of the rock itself. Students will also learn about atmospheric science, a subject that is concerned with the atmosphere and other related factors, which is divided into other areas such as meteorology and atmospheric physics. Another topic that earth science students can expect to study is the area of meteorology, which focuses on the analysis and dissection of climate-related issues and factors.
Another area of concentration in the study of earth science is the area of oceanography, a topic that is based on the study of the main bodies of water on the planet. These bodies of water are broadly grouped into marine and freshwater, with further differentiations derived from size, content, location, and the type of life it supports. In the case of freshwater habitats, students will learn about the types of water bodies that make up this group, including ponds, rivers, streams, and lakes. They will also learn the fact that the salt content, or salinity, of these water sources is low or non-existent compared to the saltiest marine water. They will also learn about the types of marine habitats including seas, estuaries and oceans, the types of organisms that can survive in such salty environments, the effects of tides and currents and other phenomena that are peculiar to that habitat.
