LUNAR ECLIPSE : A lunar eclipse occurs when the Moon passes directly behind the Earth into its umbra. This can occur only when the sun, Earth and moon are aligned exactly or very closely so, with the Earth in the middle.
SOLAR ECLIPSE : A solar eclipse is a type of eclipse that occurs when the Moon passes between the Sun and Earth, and when the Moon fully or partially blocks the Sun.
MINING : Mining is the extraction of valuable minerals or other geological materials from the earth, usually from an orebody, lode,vein, seam, reef or placer deposits. These deposits form a mineralized package that is of economic interest to the miner.
If this helps you please mark as the brainliest

Well, thank you..... i'll talk to you tomorrow as I have to sleep....I'm in school.....thank you for your time
Ores recovered by mining include metals, coal, oil shale, gemstones, limestone, chalk, dimension stone, rock salt, potash, gravel, and clay. Mining is required to obtain any material that cannot be grown through agricultural processes, or created artificially in a laboratory or factory. Mining in a wider sense includes extraction of any non-renewable resource such as petroleum, natural gas, or even water.
Thank you
Mining of stones and metal has been a human activity since pre-historic times. Modern mining processes involve prospectingfor ore bodies, analysis of the profit potential of a proposed mine, extraction of the desired materials, and final reclamation of the land after the mine is closed.
Mining operations usually 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. Work safety has long been a concern as well, and modern practices have significantly improved safety in mines.
Levels of metals recycling are generally low. Unless future end-of-life recycling rates are stepped up, some rare metals may become unavailable for use in a variety of consumer products. Due to the low recycling rates, some landfills now contain higher concentrations of metal than mines themselves
So here you go
Thank you
hope you do well in your exam best of luck then.
I will..... i'll be sure to do my very best..... thank you
