Water is a renewable resource in the sense that it replenishes itself through rain. However, it is possible to use water in ways that render it a non-renewable resource.Continue Reading
A renewable resource is any natural resource that replaces itself given enough time. The rate of replenishment must be equal to or faster than the rate of usage. As water continuously evaporates from the Earth's surface, it collects in the atmosphere to later come back to the Earth as rain. On the Earth itself surface water replenishes groundwater, and groundwater replaces surface water. With careful management and responsible usage, water is a renewable resource.
There are increasing concerns about water scarcity in many parts of the world, particularly in developing nations or regions of high population density. Only 3 percent of the Earth's water is fresh water, and only one-third of that amount is usable for drinking water. The rest of Earth's fresh water is part of ice caps and glaciers. In many of the world's most populous regions, potable water is a scare commodity because of overuse, mismanagement and pollution.
Hydroelectric power is one important use of water as a renewable resource. Water power is efficient, produces very little waste comparative to other energy sources and the water is reusable.Learn more about Natural Resources
The effects of natural resource depletion vary depending on the type of resource. Reduced water quality affects humans and animals by reducing the amount of healthy and safe drinking water, while the rapid use of fossil fuels introduces foreign and harmful toxins into waterways, the ground and the atmosphere, and affects human populations by increasing the cost of transportation.Full Answer >
A natural resource map shows the expanse of natural resources found on and in the surface of the Earth. Natural cover of the worlds, world map of natural vegetation and world map of minerals are examples of natural resource maps.Full Answer >
Petroleum is a non-renewable resource, because the natural petroleum deposits are finite and, once exhausted, there is no way to restore them. As of 2014, the Earth possesses several decades of petroleum resources to meet its needs.Full Answer >
The term nonrenewable resource is generally used to refer to the energy-providing resources of oil, coal, natural gas and uranium. Nonrenewable resources are any resources comprised solely, or in part, from elements on the periodic table and that were created through chemical reactions that either required conditions no longer found on Earth or that took millions of years to complete, making them nonrenewable in a practical sense.Full Answer >
