non renewable resources with 1 ex. and explain the ex.
Answers
Nonrenewable resources are resources that have a limited supply. More than that, these resources can't be replaced by natural means at a pace that meets its consumption. A lot of our fossil fuels, such as oil, are nonrenewable resources. In other words, if we keep using them, they will eventually run out.
In many of the examples of nonrenewable resources below, the supply comes from the Earth itself. However, since it typically takes millions of years to develop, these resources are finite. Nonrenewable energy can generally be separated into two main categories: fossil fuels and nuclear fuels. Let's take a closer look.
Fossil Fuels
Fossil fuels are derived from organic matter which has been trapped between layers of sediments within the Earth for millions of years. Organic matter, typically plants, have decomposed and compressed over time, leaving what are known as fossil fuel deposits. These deposits, and the materials produced from them, tend to be highly combustible, making them a potent energy source. They're difficult to obtain because they're typically retrieved through drilling or mining. However, many consider fossil fuels to be worth the effort for the sheer amount of energy they produce.
Crude Oil/Petroleum
Crude oil is a nonrenewable resource that builds up in liquid form between the layers of the Earth's crust. It's retrieved by drilling into the ground and ocean floor, and pumping the liquid out. The liquid is then refined and used to create many different products. Crude oil is a very versatile fuel and is used to produce things like plastics, artificial food flavorings, heating oil, petrol, diesel, jet fuel, and propane. The top three oil-producing countries are Russia, Saudi Arabia, and the United States. Petroleum deposits that begin to form underground are known as oil sands, bitumen, or bituminous sands. Bitumen is too thick to be pumped under natural conditions. Scientists refer to it as cold molasses. With special machinery, much of this is being mined in Alberta, Canada, serving as a major energy source for Canadians as well as people all around the world.
