What approximate percentage of land is used for housing worldwide A 2 B 26 C 52 D 100?
52% approximate percentage of land is used for housing worldwide.
What approximate percentage of land is used for housing worldwide Brainly?
The correct answer is option a. “2%”. It has been reported that approximately 2.7% of the land corresponds to cities around the world. Housing is the most important land usage in cities, therefore its use plus the contribution of housing in rural areas gives around 2% of land used for housing worldwide.
What was ultimately responsible for London’s Killer Fog in 1952?
Study lead author Renyi Zhang, an atmospheric scientist at Texas A&M University, said that sulfate was a big contributor to the deadly London fog. Sulfuric acid particles, which formed from the sulfur dioxide that was released from the burning of coal, were also a component of the fog.

What are the negative effects of mining?
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 …
What is the environmental impact of the mining industry?
Mine exploration, construction, operation, and maintenance may result in land-use change, and may have associated negative impacts on environments, including deforestation, erosion, contamination and alteration of soil profiles, contamination of local streams and wetlands, and an increase in noise level, dust and …
What is the 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.
Why is open pit mining cheaper?
The cost advantage of open pit mining to investors is a matter of scale. It is cheaper to operate an open pit mine because less manpower and equipment is required. Strip mining, or open pit mining is profitable sooner than a shaft mine because more ore can be extracted from an open pit mine and more quickly.
How does open pit mining affect the environment?
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 is the environmental impact of open pit mining?
The effects of open-pit mining and mineral processing plants on the environment include land degradation, noise, dust, poisonous gases, pollution of water, etc.
How does mining destroy the environment?
Mines are known to cause severe environmental problems. 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 pros and cons of strip mining?
List of Pros of Strip Mining
- It is much more efficient compared to underground mining. Those who advocate for strip mining believe that the recovery rate of materials is higher using the method.
- It is lower in cost.
- It is safer than underground mining.
- It is hazardous to human health.
- It is harmful to the environment.
Is strip mining safe?
On a production basis, comparing fatalities per million tons, strip mines are over four times safer than underground mines; and on an exposure basis, comparing fatalities per million man hours, strip mines are approximately twice as safe.
How does mining affect human health?
Health impacts due to inhalation of PM emission from surface mines—medical evidence. PM exposure to surface mining workers lead to some common diseases such as asthma, black lungs, silicosis, asbestosis, inflammation, bauxite fibrosis and siderosis (Singh et al., 2009).
Is strip mining effective?
Strip mining is the least efficient method of mining, AND you wear out your tools on mostly cobblestone, AND you are left with an enormous hole in the ground that just looks ugly. Then you can use a water bucket to turn the lava level into floors for your branch mine when you encounter them.
Is it better to mine at y11 or Y12?
If you mine y11 you see these coords (y9, y10,y11 and y12) diamond rates at Y12 is much lower than y8 so if you mine at y10 you see (y8, y9,y10 and y11) This way you will increase your diamond luck. And always mine the top block first so if there is lava you see it before it spreads all over you.
Why is strip mining bad?
Surface mining (another name for “strip mining”) can severely erode the soil or reduce its fertility; pollute waters or drain underground water reserves; scar or altar the landscape; damage roads, homes, and other structures; and destroy wildlife.
What is the best level to strip mine?
y11
What is the best y level to strip mine for diamonds?
Due to being the safest layers to mine where all ores exist in reasonable quantities (especially diamond), layer 10 to 15 are usually considered the best area in which to start mining.
Does TNT destroy diamond ore?
By placing TNT, you will end up destroying the resources, so don’t risk it. However, since it will wind up destroying most dropped items, it is of no use in breaking blocks to collect their resources. I suggest trying to find some iron and then mining it otherwise you will lose those precious diamonds.
How do you find diamonds fast?
A very effective way to find Diamonds is to branch mine. This involves covering a lot of surface area by making a 2×2 tunnel and digging individual “branches” out from it every third block. By doing this you’re covering a lot of ground quickly without breaking any unnecessary blocks.
At what coordinates can you find diamonds?
Diamonds occur between the Y-coordinates 5 and 16, though they occur most often between layers 5 and 12. You can check your Y-coordinates by opening your map (console and PE), or by pressing F3 (PC) or Alt + Fn + F3 (Mac).
What type of soil are diamonds found in?
Pockets of Minerals Diamonds are most abundant in stable layers of the Earth’s crust called cratons, and are usually found in cratons that are at least 570 million years old.
What’s the best level for diamonds?
Finding Minecraft diamonds is no easy task and for good reason – Minecraft diamonds create a whole bunch of durable weapons and armour. The Minecraft diamond level is anywhere below layer 16, but the optimum diamond level is between layers 5-12.
