Mining

Yes i is. Though some people say it is a renewable resource too. But, scientificly approved, it is considered a non-renewable resource because it takes too long to renew its self. Ask more questions if you need any more data! I am glad to help!

The most useful physical properties for identifying minerals are color, luster, hardness, cleavage, fracture, streak, and specific gravity. These properties help geologists distinguish between different minerals based on their unique characteristics.

underground mining is done when the rocks, minerals of gemstones are too far

underground to get out with surface mining some kinds of underground mining are

Borehole Mining

Drift Mining

Hard Rock Mining

Shaft Mining

Slope Mining

The sandstone is older because it must have been there first to provide the small pieces found in the granite. This relationship implies that the sandstone layer was already in place before the granite formed and incorporated fragments of the sandstone.

Mining: ores, precious metals and stones

Construction materials: sand, gravel, decorative stone (limestone, marble etc)

Energy: oil, natural gas, peat, uranium

Tourism & recreation: landscapes (Burren, Giant's Causeway etc) and activities (rock climbing, hill walking, caving etc)

· Iron ore fines (less than 6mm)

· Sized ore (size 5mm to 20mm)

· Lump ore (size 10mm to 40mm)

Iron ore fines are created as a result of mining, crushing and processing the larger pieces of ore.

The reason lump is preferred is that when it is fed into a blast furnace for steel-making, its particle size allows oxygen or air to circulate around the raw materials and melt them efficiently.

The fine iron ore products have first to be processed into what is called sinter, otherwise it will effectively smother the air flow in the blast furnace.

Hydraulic mining and dredging technologies gradually replaced placer mining in the late 1800s and early 1900s. These methods allowed for more efficient extraction of gold by using water to dislodge and transport material, increasing the scale and productivity of mining operations.

A hard substance composed of one or more minerals or mineral-like substances is known as a rock. Rocks are naturally occurring solid aggregates of minerals or mineraloids. They can vary in composition, density, color, and texture depending on the minerals present.

Diamonds are mined, not quarried. Diamond mining involves extracting diamonds from the earth's crust, typically through open-pit or underground mining operations. Quarries, on the other hand, are used to extract building materials like stone, sand, and gravel.

Love is often considered the hardest thing on Earth, as it requires vulnerability, sacrifice, and understanding to truly connect with another person on a deep emotional level.

Costs of surface mining can include equipment and machinery, labor, permits, environmental reclamation, transportation of materials, and ongoing maintenance. Additionally, there may be costs associated with mitigation of environmental impacts, such as water pollution or habitat destruction. Overall, the costs can vary depending on factors like the size of the operation, location, and regulatory requirements.

The mine that collapsed in Chile in August 2010 was called the San Jose mine.

A "brownfield site" is one that has previously been built on (including ex-industrial sites). They are targeted by the UK government for new building rather than building on fresh countryside ("greenfield sites").

The Earth is estimated to be around 4.5 billion years old, formed approximately 9 billion years after the formation of the universe. This age is determined through radiometric dating of rocks and meteorites.

Iron ore is considered a non-renewable resource because it is a finite material that is extracted from the Earth through mining processes. While new iron ore deposits may be discovered, the rate of extraction exceeds the rate of replenishment, making it unsustainable in the long term.

Granite is an Igneous rock, sandstone is a sedimentary rock, sandstone is made up of grains that are bonded together lightly, you can even rub some of the grains off with your hands.

Granite is not made from grains, they are deep into the mountains, and used for building materials, they even have crystals in them.

The methods used to extract minerals from ores vary; each ore has its own suitable method(s) of extraction. For example, iron can be extracted from its ore through the blast furnace method, while more reactive minerals (such as aluminum) may need to be extracted through electrolysis.

In Leadville, Colorado, both surface and subsurface mining were conducted. Surface mining involved open pit mining for materials like gold and silver. Subsurface mining involved digging shafts and tunnels deep underground to extract minerals like lead and zinc.

The world's chief diamond mining center is Botswana, particularly at the Jwaneng and Orapa mines. Botswana is one of the world's top diamond producers, known for its high-quality diamonds and efficient mining operations.

People can obtain water from an aquifer by drilling a well into the ground until it reaches the water table of the aquifer. A pump is then installed to lift the water to the surface for use. Proper management and monitoring of groundwater extraction is essential to ensure sustainable use of the aquifer's water resources.

A tornado can cause destruction by uprooting trees, damaging buildings, and throwing debris at high speeds. It can also result in injuries and fatalities due to its strong winds and flying objects.

The study of rocks is called petrology. It involves examining the composition, structure, and formation of rocks to understand their properties and geologic history. Petrologists use various techniques such as microscopy, chemical analysis, and field observations to study rocks.

The deepest point on land is in Antarctica. It is called the Bentley Subglacial Trench, and it reaches a depth of about 8,200 feet below sea level.
