Could you show me a example of it
Subheadings give the reader an idea of what will be discussed in the section. For example, 'How Did WWII Shape Daily Life?' This subheading shows the reader that it will be about how WWII changed the daily lives of people. By the end of the section, the reader should have a firm answer to the question.
Answer:
biosphere interacting with the hydrosphere.
Explanation:
Since a woman is a living being, she belongs to the system of biosphere, where all other living things, such as animals, plants, etc. belong. On the other hand, a glacier belongs to the system of hydrosphere. Hydrosphere has to do with water - and since glacier is made of ice, or frozen water, it is obvious why it belongs to this system and not, let's say, geosphere (solid parts of the Earth) or atmosphere (gas parts of the Earth).
