Transcript of biosphere, hydrosphere, atmosphere & lithosphere

this presentation is about the biosphere, hydrosphere, atmosphere, and the lithosphere.
Biosphere: Isabella Rocca
Hydrosphere: Jill Kay
Atmosphere: Kylie Parr
Lithosphere: Hailey Foster
mining disrupts the lithosphere, coal and surface mining have the most impact because they require large areas of land and raise some environmental problems like soil erosion, dust, noise, and water pollution and local biodiversity.

- strip mining can cause deforestation which can kill plants and animal life.
- Definition of Atmosphere: the envelope of gases surrounding the earth or another planet.

biosphere, hydrosphere, atmosphere & lithosphere
the regions of the surface, atmosphere, and hydrosphere of the earth (or analogous parts of other planets) occupied by living organisms
-The biosphere is all about life. Physical geographers use the term biosphere to describe our living world. All of the microbes, plants, and animals can be found somewhere in the biosphere.
- People play an important part in maintaining the flow of energy in the biosphere. Sometimes, however, people disrupt the flow. For example, in the atmosphere, oxygen levels decrease and carbon dioxide levels increase when people clear forests or burn fossil fuels such as coal andoil. Oil spills and industrial wastes threaten life in the hydrosphere. The future of the biosphere will depend on how people interact with other living things within the zone of life.
Encyclopædia Britannica:

How humans affect the atmosphere: As human society has grown and advanced, its effects on the environment and the atmosphere have become more and more pronounced. One of the biggest issues regarding the effects of humanity on the atmosphere is the long-term nature of the changes. Smog hanging over cities is the most familiar and obvious form of air pollution. But there are different kinds of pollution—some visible, some invisible—that contribute to global warming Many human activities release trace amounts of gases or particulates that can result in a variety of impacts on human health and the environment.
Atmosphere effects: As solar radiation passes through the atmosphere, gasses, dust and
aerosols absorb the incident photons. Light is absorbed as it passes through the atmosphere and at the same time, it is subject to scattering.

Hydrosphere is the liquid water component of the Earth.
Includes oceans, seas, lakes, ponds, rivers and streams

- Pollution of the hydrosphere is a major problem. When we think of pollution, we sometimes only think of things like plastic, bottles, oil and so on. But any chemical that is present in the hydrosphere in an amount that is not what it should be is a pollutant.

- very small percentage of the hydrosphere's water is available as freshwater
- most common forms of pollution in the hydrosphere are waste products from humans and from industries, nutrient pollution e.g. fertilizer runoff which causes eutrophication (an excess of nutrients in the water leading to excessive plant growth) and toxic trace elements such as aluminium, mercury and copper
The outer part of the earth, consisting of the crust and upper mantle, about 100 kilometers (62 miles) thick.
What we can do as a solution:

- we can recycle
- don't throw any waste in the ocean to save
- don't litter near beaches
Solutions- less factories, less gas
powered cars, and people understanding
how important the atmosphere is
to us.
solutions :
-Be careful
making fires in the forest
so you don't burn them.
-Prevent killing animals and other living things.
-Don't cut down trees .
