1. The right answer is B. Geosphere
The geosphere is usually called an earth's sphere. The word thus names a phenomenon of the earth, which often lays shell-like around the whole celestial body. Within a period of 150 years, the geosphere term experienced at least ten different definitions, of which five are still used today in the German-speaking world. As a result, there is currently no agreement on the content, extent and extent of the geosphere.
2. The right answer is A. Biosphere
The biosphere is the system formed by all living things on planet Earth and their interrelations that influence the environment, as a medium on organisms. This meaning of "living envelope" of the Earth is the most widely used, but it sometimes refers to the space in which life develops.
3. The right answer is A. Atmosphere
The atmosphere is, in the broad sense, a gaseous layer that envelops some stars. The Earth as well as other planets or stars are provided. An atmosphere may contain particles in suspension (dust, aerosols, etc.) or reach very high temperatures, as is the case for stars, thus generating a light emission.
