Explanation:
Answer: The ice has been melting and declining
Explanation:
Due to an increase in industrialization, global warming is occurring. This has increased the average temperature around the globe considerably.
As you probably know, ice needs to be in a cold environment to stay frozen. <em>Arctic sea ice</em>, which is ice that floats in the sea near the Arctic, <em>has been </em><em>melting</em> due to global warming.
In addition, the land ice on Antarctica and Greenland has <em>also been </em><em>melting</em> due to global warming. The increase in average temperatures around the globe has created an environment that is <em>too warm</em> for ice.
In conclusion, <em>global warming</em> has caused Arctic sea ice, and land ice on Antarctica and Greenland, to <em>melt</em>. The globe <em>is warmer than it once was</em>. This means that the water that once was frozen is now melting. If we don't stop heating the planet, <em>sea levels will rise </em>due to the melting ice, and catastrophe will occur. Tens of thousands of animals will die, homes will be lost, and storms will increase in intensity and frequency if we don't reverse the effects of global warming <u><em>now.</em></u>
Save the Arctic, please.
It is formed by plate tectonics
Answer:
It is important because:
Explanation:
It is one of the largest reserves of natural gas found in the country, and adds considerably to the natural gas supply. The reason the formation is so important lies in its economic significance. Shale gas is much cheaper than oil, and the Marcellus Shale significantly enhances our reserves.
Hope this helps!~
