The four major divisions of earth inside the earth are: the crust, the mantle, the outer core, and the inner core. Some of these have sub-divisions as well. Below the crust is the mantle which is a flowing plastic material between solid and liquid that continuously reshapes the crust through earth quakes, volcanoes, and shifting entire continents.
The outer core is a mass of molten metal, mostly iron which spins around the inner core, resulting in the earth's magnetic field, which keeps us safe from bombardment by cosmic rays. The inner core is the dynamic solid center of the earth that maintains our steady daily rotation and tilt that results in our seasons. What are the four major divisions of Earth?

Scientists working in these fields must combine various scientific disciplines physics, chemistry and biology with math, geography and natural history. Subdivisions of earth science include environmental science, which studies populations of animals and plants in connection with their ecosystems; geology, which is the study of the Earth's crust; water science, which includes oceanography and hydrology; and atmospheric science, including climatology and weather. Environmental science is the study of how populations of animals and plants are affected by their ecosystems.
Environmental science often addresses the effects of human activities -- such as pollution, deforestation and industrialization -- on ecosystems and organisms. Other environmental fields include environmental policy, natural resources management, pollution management, hazardous materials policy and marine and wildlife management.
Geology is the study of the Earth's crust, specifically the rocky portions of the crust. When used more broadly, the term geology can also refer to the study of the natural history and structure of the earth.
