Besides oil what else is found inside the earth

We have collated the detailed and accurate answers for all questions given in chapter 12 of class 5 EVS book. These solutions will give a pleasant learning experience to all students of class 5.

As each of us use the Earth's natural resources on a human time scale, it is important to consider that mineral resources form on geologic timescales, and the vast difference between the two. The items in this case are just a few of the ways that we use rocks and minerals in our everyday lives. Production of this gallery was generously supported by The Ford Family Foundation. Gypsum is ubiquitous in our lives as the basis for drywall. It contains water in its mineral structure, which it loses when heated, providing an initial line of defense against building fires. In the time before dry-erase boards, all education relied upon chalkboards made from slate, which is clay that has been cooked by heat and pressure deep within the earth.

Mining is the extraction of valuable geological materials and minerals from the surface of the Earth. Mining is required to obtain most materials that cannot be grown through agricultural processes , or feasibly created artificially in a laboratory or factory. Ores recovered by mining include metals , coal , oil shale , gemstones , limestone , chalk , dimension stone , rock salt , potash , gravel , and clay. The ore must be a rock or mineral that contains valuable constituent, can be extracted or mined and sold for profit. Modern mining processes involve prospecting for ore bodies, analysis of the profit potential of a proposed mine, extraction of the desired materials, and final reclamation or restoration of the land after the mine is closed. The exploitation of these deposits for raw materials is dependent on investment, labor, energy, refining, and transportation cost. Mining operations can create a negative environmental impact, both during the mining activity and after the mine has closed. Hence, most of the world's nations have passed regulations to decrease the impact; however, the outsized role of mining in generating business for often rural, remote or economically depressed communities means that governments often fail to fully enforce such regulations. Work safety has long been a concern as well, and where enforced, modern practices have significantly improved safety in mines. Unregulated or poorly regulated mining, especially in developing economies , frequently contributes to local human rights violations and environmental conflicts. Mining can also perpetuate political instability through resource conflicts. Since the beginning of civilization, people have used stone , clay and, later, metals found close to the Earth's surface. These were used to make early tools and weapons; for example, high quality flint found in northern France , southern England and Poland was used to create flint tools. The mines at Grimes Graves and Krzemionki are especially famous, and like most other flint mines, are Neolithic in origin c.

Iron and Aluminum It's hard not to experience iron and aluminum in our everyday lives.

There are many different sources of energy but they are all either renewable or nonrenewable energy sources. Renewable and nonrenewable energy sources can be used as primary energy sources to produce useful energy such as heat, or they can be used to produce secondary energy sources such as electricity and hydrogen. Nonrenewable energy sources account for most U. These energy sources are called nonrenewable because their supplies are limited to the amounts that we can mine or extract from the earth. Coal, natural gas, and petroleum formed over thousands of years from the buried remains of ancient sea plants and animals that lived millions of years ago, which is why we also call those energy sources fossil fuels.

What does mantle rock look like? You can't go to the mantle, but small pieces of the mantle can come to you. Kimberlite forms deep in the mantle and can emerge in the crust during violent eruptions. Kimberlite can contain diamonds. Most kimberlite reached the surface much earlier in Earth's history. Beneath the crust is the mantle. The mantle is made of hot, solid rock. Scientists know this because of seismic waves, meteorites, and the heat that comes from inside the planet.

Before you can learn about plate tectonics, you need to know something about the layers that are found inside Earth. These layers are divided by composition into core, mantle, and crust or by mechanical properties into lithosphere and asthenosphere. How do scientists know what is inside the Earth? Rocks yield some clues, but they only reveal information about the outer crust.

Uranium is a highly radioactive element. In both dramatic events, mountains depressed the North American continental margin and drove subsurface fluids toward the interior of the continent. The greatest dangers from oil spillage are found in the transportation phase—and tanker transportation is the most dangerous of all. When it reaches solid bedrock, water sustains weathering of minerals and carries away the residue. There, almost a million ounces of gold was recovered between and Retrieved 26 October The World Bank has been involved in mining since , mainly through grants from its International Bank for Reconstruction and Development , with the Bank's Multilateral Investment Guarantee Agency offering political risk insurance. Makeshift sails lead fresh air underground. Rocks and Hard Places. As the Earth evolved, the abundances of various types of mineral deposits also changed Figure 4.

Some people think the oil inside the earth is part of a support structure that helps keep the world round. How it got there and how humans get it out of there has a lot to do with the question of how much there is and what might be the consequences of future drilling.

In high wall mining, the remaining part of a coal seam previously exploited by other surface-mining techniques has too much overburden to be removed but can still be profitably exploited from the side of the artificial cliff made by previous mining. However, mineral deposits are generally more complex because there is not a single source material, as there is in petroleum formation. The instream flow requirement represents the minimum streamflow necessary to preserve aquatic and associated ecosystems. As these are unacceptable, the mining industry has developed approaches that can ameliorate the effects. Tile 15 Description. Since the advent of the Iron Age, miners have descended into shafts that invade the crust. Blasting was much faster than fire-setting and allowed the mining of previously impenetrable metals and ores. The chromite occurs in layers, which resemble sedimentary layers, except these layers occur within a crystallizing magma chamber. But many aspects of our water resources remain undefined or even unrecognized. Mining Techniques The mining style is determined by technology, social license, and economics. In North America every individual consumes or. Indications from wells and outcrops suggest that fluids may be present in significant amounts at most crustal levels, although they are locally sporadic, and that the surrounding rocks undergo chemical modification as a result of contact with migrating fluids. The rising sea levels of transgressions create onlapping sediments, regressions create offlapping. Various exploration approaches can be used in the search for economically viable deposits.
