What is most likely consequence of open-pit mining on plant life?
The soil looses it's fertility. This converts the mining site into a barren land. Therefore the complete loss of plant life in the area occupied by the surface mine is the most likely consequences of open pit mining on plant life.
What are 3 environmental problems caused by open-pit mining?
Some of these effects include erosion, formation of sinkhole, biodiversity loss and contamination of groundwater by chemical from the mining process in general and open-pit mining in particular. As such, a repeatable process to evaluate these effects primarily aims to diminish them.
What happens during open-pit mining?
Open-pit mines are used when deposits of commercially useful ore or rocks are found near the surface. To create an open-pit mine, the miners must determine the location of the ore. This is done through drilling of probe holes in the ground, then plotting each hole location on a map.
What are the disadvantages of open-pit mining?
1.1 Features, technical and economic indicators of open pit development
| Advantages | Disadvantages |
|---|---|
| High production rate (essentially unlimited, although small surface mines also possible) | Limited by stripping ratio |
| Lowest cost along with open cast mining | High capital investment associated with large equipment |

How does open-pit mining affect water?
The impact of mining on surface and groundwater is due to spill/tailing, erosion, sedimentation, acid mine drainage, lowering of water table, subsidence, disturbance on hydrological cycle and rainfall. Acid mine drainage is considered one of mining's most serious threats to water resources.
Why is open-pit mining so destructive?
This type of mining is particularly damaging to the environment because strategic minerals are often only available in small concentrations, which increases the amount of ore needed to be mined. Environmental hazards are present during every step of the open-pit mining process.
Why is open-pit mining devastating to the environment?
And thus, open-pit mining has a lot of devastating effects on the environment. According to a study, open pit mining exposes 8 to 10 times more waste materials to the environment than underground mining. These effects substantially affect the soil, water, air, and living beings near the mining area.
What kind of damage can mining do to the environment?
Mining can pollute air and drinking water, harm wildlife and habitat, and permanently scar natural landscapes. Modern mines as well as abandoned mines are responsible for significant environmental damage throughout the West.

These effects substantially affect the soil, water, air, and living beings near the mining area.
How does open-pit mining cause soil erosion?
Surface mining destroys landscapes, forests and wildlife habitats at the site of the mine when trees, plants, and topsoil are cleared from the mining area. This in turn leads to soil erosion and destruction of agricultural land. When rain washes the loosened top soil into streams, sediments pollute waterways.
What are the effects of mining on the environment?
Mining can pollute air and drinking water, harm wildlife and habitat, and permanently scar natural landscapes. Modern mines as well as abandoned mines are responsible for significant environmental damage throughout the West.
What are the consequences of excessive mining in an area?
Across the world, mining contributes to erosion, sinkholes, deforestation, loss of biodiversity, significant use of water resources, dammed rivers and ponded waters, wastewater disposal issues, acid mine drainage and contamination of soil, ground and surface water, all of which can lead to health issues in local …
How does mining affect the soil?
Mining activities severely damage the original geological formations and ecosystems, causing inevitable damage to the soil. In this study, the soils from mining areas were characterized by high pH, poor soil quality, and high level of trace metals contamination.
How does mining affect the environment quizlet?
Water-pollution problems caused by mining include acid mine drainage, metal contamination, and increased sediment levels in streams. Sources can include active or abandoned surface and underground mines, processing plants, waste-disposal areas, haulage roads, or tailings ponds.
How mining affect the soil?
Mining activities severely damage the original geological formations and ecosystems, causing inevitable damage to the soil. In this study, the soils from mining areas were characterized by high pH, poor soil quality, and high level of trace metals contamination.
How does mining affect vegetation?
Damage to Land Resources Strip mining eliminates existing vegetation and alters the soil profile, or the natural soil layers. Mining disturbs and may even destroy the beneficial micro-organisms in the topsoil.
Why is open pit mining so devastating to the environment?
It completely removes any available topsoil. Open pit mining is so devastating to the environment because it exposes dangerous chemicals buried in the earth's crust.
What are the three causes of harmful effects of mining?
- Respiratory complications.
- Injuries and fatalities.
- Cancers due to radioactive material exposure.
- Poisoning and organ damage due to heavy metals exposure.
How does open pit mining cause soil erosion?
Surface mining destroys landscapes, forests and wildlife habitats at the site of the mine when trees, plants, and topsoil are cleared from the mining area. This in turn leads to soil erosion and destruction of agricultural land. When rain washes the loosened top soil into streams, sediments pollute waterways.
Which of the following is a long term consequence of mining on Earth?
The effects can result in erosion, sinkholes, loss of biodiversity, or the contamination of soil, groundwater, and surface water by the chemicals emitted from mining processes. These processes also affect the atmosphere from the emissions of carbon which have an effect on the quality of human health and biodiversity.

Mining is the extraction of minerals and other geological materials of economic value from deposits on the Earth. Mining adversely affects the environment by inducing loss of biodiversity, soil erosion, and contamination of surface water, groundwater, and soil. Mining can also trigger the formation of sinkholes.
What are the risks associated with mining?
Cave-ins, explosions, toxic air, and extreme temperatures are some of the most perilous hazards observed to take place in underground mining. Valuable minerals are found all over the world. And most often the only way to get to them is by mining into the earth's ground.

What is the effect of mining to plants animals and humans?
When mining, extensive areas of land and vegetation are cleared. The viability of the land for farming activities deteriorate and animals loss their habitats. Biodiversity losses are, therefore, experienced in the area due to habitat modification in terms of factors such as pH changes and temperature changes.
