Strong winds, I think! :)
Answer:
The natural resources of the Arctic are the mineral and animal resources within the Arctic Circle that can provide utility or economic benefit to humans. The mineral resources include major reserves of oil and natural gas, large quantities of minerals including iron ore, copper, nickle, zinc phosphates and diamonds.
Explanation:
The Arctic resources race refers to the competition between global entities for newly available natural resources of the Arctic. Under the United Nations Convention of the Law of the Sea, five nations have the legal right to exploit the Arctic’s natural resources within their exclusive economic zones: Canada, Russia, Denmark, Norway, and the United States (though the U.S. has yet to ratify the treaty, it considers the treaty to be customary international law and abides by it).
The Arctic region and its resources have recently been at the center of controversy and pose potential conflicts between nations that have differing opinions of how to manage the area, including conflicting territorial claims. In addition, the Arctic region is home to an estimated 400,000 indigenous people. If the ice continues to melt at the current rate, then these indigenous people are at risk of being displaced. The acceleration of ice depletion will contribute to climate change as a whole: melting ice releases methane, ice reflects incoming solar radiation, and without it will cause the ocean to absorb more radiation (albedo effect), heating up the water causing more ocean acidification, and melting ice will cause a rise in sea level.
Answer: a. algal bloom
Explanation:
The availability of food in the systems can tell the types and numbers of organisms in the systems by checking which types of organisms eat the food available as well as the quantity available to see the number of organisms.
Temperature and dissolved oxygen levels also play a huge part in determining the feasibility of organisms staying in the system. The availability of nutrients goes hand in hand with the availability of food in determining the organisms present.
Algal bloom is not a factor in determining the types and numbers of organisms found in a system because the conditions that caused this bloom might not be suitable for other organisms as well.
Answer:
Carbon dioxide and water vapour concentrations will lead to change in temperatures.
Explanation:
- Most of the common volcanic gases include carbon dioxide, sulphur dioxide and hydrogen sulphide along with small quantities of volatile compound and elements present such as hydrogen, helium and chloride etc.
- The carbon dioxide and water vapour alter the temperature During the experiment the concentration of carbon dioxide goes up and the temperature goes down. Thus volcanic eruption often leads to global cooling.
