Earth is a planet that has numerous spheres. All of the spheres are constantly interacting with each other, depend on each other, and have big influence on each other, making one very complex interconnected system.
The lithosphere is the sphere that contains all of the landforms on Earth. This sphere is solid, and it is the one that forms the landmasses on our planet.
The biosphere is the sphere that contains all of life forms on Earth. Animals, plants, bacteria, fungi, humans, all are part of this sphere, and make this planet unique in its surroundings in the universe.
The atmosphere is the sphere that contains the air. This sphere is located between the surface of Earth and the space. It is the sphere that provides suitable conditions for life, creates weather, and protection.
The hydrosphere is the sphere that contains all of the water on Earth. It is the sphere that forms all of the oceans, seas, lakes, rivers, marshes etc. This sphere can be found as freshwater, saline water, and as frozen (often also put into separate sphere, cryosphere).
Honestly I just looked at the prefixes and determined the correct answers based off of those. biosphere goes to life as bio means life. Hydrosphere goes to water because hydro means water. Atmo means air and litho means land.
"<em>Big Apple</em>" is a nickname for New York City. It was first popularized in the 1920s by John J. Fitz Gerald, a sports writer for the New York Morning Telegraph. Its popularity since the 1970s is due in part to a promotional campaign by the New York tourist authorities.
