Answer:
Crust
Explanation:
According to the recently given theory, The theory of Seafloor Spreading the magma or lower most part of the earth's surface which sometimes bursts as (molten lava) plays substantial role in the formation of new crust. This is because when magma or molten lava from the bottom most part of the earth reaches the surface of earth, it cools down and pushes the already existing surface of the earth like rocks from both directions. This pushing of rocks cause the formation of new crust by the molten materials when it cools down.

Surface mining, which is also known as strip mining, is when soil and rock overlaying mineral deposit is removed. It can cause habitat destruction, air pollution from dust particles, soil erosion and pollution. Subsurface mining is removing deposits from the Earth by drilling underneath layers of rock and dirt. To keep the pathways clear, <span>mining companies have to pump out large amounts of water, which go into surface ecosystems. That disrupts the ecosystem by changing the pH conditions of soil and water sources. Placer mining is mining of stream bed deposits for minerals, a way of obtaining minerals and metal resources. Although, because it is small, causes less damage to the surrounding environment it still can disrupt river ecosystems with pollution and sediments.

No they can... But if you talk to your plants it helps they stay healthy because of the oxygen you are giving them.
<span>The Left-sided Problem of the heart involves the lack of enough supply of oxygen induced blood and the blood which is unable to reach the heart goes to lungs causing breath issues. Another issue with this problem is that left side of the heart pumps blood into the body, so when it fails, less blood will be pumped into the arteries.</span>
