PRESENTATION OUTLINE
RENEWABLE AND NON-RENEWABLE RESOURCES
Non-Renewable Resources.
💎Non-Renewable resources are natural resources that can be depleted or used to the point that they are no longer available.
EXAMPLE OF NON-RENEWABLE RESOURCES:
- Coal
- Oil
- Natural gas
- Diamonds
- Metals
- Other minerals.
Coal.
coal comes from energy that was stored in giant plants that lived hundreds of millions of years ago.
Diamonds.
Are nonrenewable because they form over millions of years. So once there destroyed, it will take a great amount of years to form a diamond again.
💧Freshwater💦
Depletion of freshwater in an area caused by increased demand by population living there, by wasteful use of water, or by pollution, can result in water not being available in needed quantities or being unfit for natural gas.
Living Resources.🐼
Depletion of living resource, such as trees being removed without being replanted, can contribute to environmental changes in the land, air, and water in the area.
As the number of people on Earth gets larger, the need for natural resources increases. The terms reduce, reuse, recycle and protect are important ways that people can be involved in conservation of natural resources.
Reducing.
Involves making a decision to not use a resource when there is an alternative, such as walking or riding a bicycle rather than traveling in a car.
Reusing.
Involves finding a way to use a resource again without changing it or reprocessing it, such as washing a drinking glass rather than throwing away plastic or styrofoam.
Recycle.
Involving reprocessing a resource so that the materials can be used again as another item, such as metals, glass plastics being remade into new metal or glass products or into fibers.
Protecting.
Involves preventing the loss of a resource, usually living things, by managing their environment to increase the chances of survival, such as providing wildlife preserves for endangered animals.
Renewable resources.
Renewable resources are replaced through natural processes at a rate that is equal to to greater than the rate at which they are being used. Air, freshwater, soil, living things, and sunlight are renewable resources.
Photosynthesis.
Air can be cleaned and purified by plants during the process of photosynthesis as they remove carbon dioxide from the air and release oxygen.
Water cycle.
Allows earth's water to be used over within environment
Topsoil is formed to replace soil that has been carried away by wind and water.
Trees and other new plants grow to replace those that have been cut down or died.
Animals are born to replace animals that have died.
Sunlight,or solar energy, is considered a renewable resource because it will continue to be available for billions of years. It provides a source of energy for all processes on earth.
