Geoscience - concerns the study of geology, soil science, volcanoes, and Earth’s crust as they relate to the environment. The scientists who take part in this field of study are the soil scientists, physicists, biologists, and geomorphologists.

It analyzes the relation of the Earth’s atmosphere to the other systems. This encompasses a wide variety of scientific studies relating to space, astrology, and the Earth’s atmosphere: meteorology, pollution, gas emissions, and airborne contaminants.
