Answers
Answer:
2.Air is a mixture of nitrogen, oxygen, carbon dioxide, water vapors, and some other gases. It also contains dust particles.
Ans 1)The biosphere provides a base for the food chain, a food network in which material and energy are distributed through animals, contributing to complex systems that help to sustain the environment and the survival of species. ... -The biosphere is therefore important for the survival and life of living organisms
Ans 2 •)Air is mostly gas
The air in Earth's atmosphere is made up of approximately 78 percent nitrogen and 21 percent oxygen. Air also has small amounts of lots of other gases, too, such as carbon dioxide, neon, and hydrogen
Ans 3: The atmosphere consists of gases that envelop the Earth. The lithosphere refers to the rocks of the Earth's surface and upper mantle, or the depth of the plates
Ans 4:) Humans impact the physical environment in many ways: overpopulation, pollution, burning fossil fuels, and deforestation. Changes like these have triggered climate change, soil erosion, poor air quality, and undrinkable water
Ans 5 )) All the spheres interact with other spheres. For example, rain (hydrosphere) falls from clouds in the atmosphere to the lithosphere and forms streams and rivers that provide drinking water for wildlife and humans as well as water for plant growth (biosphere). ... Flooding rivers wash away soil.
