In Congo’s sun-scorched and dusty south, thousands of miners scour underground tunnels hunting for cobalt. Many of them work by hand. That’s why they are known as creuseurs — French for diggers.
They don’t use power tools. They don’t wear face masks and often no gloves. They do it because they live in one of the poorest countries in the world, and cobalt is valuable. The mineral is essential for the lithium-ion batteries found in smartphones and many electric vehicles. Most of the world’s cobalt supply comes from the Congo region. These cobalt-laden chunks of rock leave the country destined for refineries in Europe and China, where they enter the complex supply chains of some of the largest technology and automotive firms.
Creuseurs know their work is physically dangerous. Death and injury from tunnel collapses are not uncommon. Children sometimes join their older brothers and fathers in the mines
Was that detail enough ??eh??
Btw the answer was from google
Answer:
The first theory is: as the cloud collapsed to form a galaxy, it's spin is what determined what type of galaxy it became. Some theorists believe that spiral galaxies were formed from clouds that had a significant spin. ... The second theory is that elliptical galaxies were formed from collisions of spiral galaxies
Answer:
1384.83 miles .
Explanation:
1 .
Conversion of kilometer to mile ,
1 kilometer is equal to 0.621 mile ,
The lower mantle is 2230 km can be converted to miles , by simply multiplying by the value 0.621 .
Hence ,
the conversion is done as follows ,
2 .
Lower mantle = 2230 km = 2230 * 0.621 = 1384.83 miles
hence , the value of lower mantle is 2230 km and in terms of mile is equal to 1384.83 miles .
