Environmental scientists study the interactions between organisms and their environment, known as ecology, and the interactions between human activities and the environment, including pollution and resource consumption.
The two main types of interactions studied in environmental science are abiotic interactions (involving non-living factors like temperature, water, and soil) and biotic interactions (involving living organisms and their relationships with each other and their environment).
The main interactions between molecules of hydrogen chloride are dipole-dipole interactions. Hydrogen chloride is a polar molecule with a partially positive hydrogen end and a partially negative chlorine end. These partial charges attract neighboring hydrogen chloride molecules, resulting in dipole-dipole interactions.

Some interactions between the geosphere and the atmosphere include weathering of rocks releasing minerals into the atmosphere, volcanic eruptions emitting gases and ash into the atmosphere, and dust storms carrying sediment from the geosphere into the atmosphere. These interactions play a role in shaping both the geosphere and the atmosphere.
