Answer:
<u>Climate change as catastrophic, irreversible this article is taken from Guardian news</u>paper.
Explanation:
- As global warming is a long rise in the average temperatures of the earth climate it's a major aspect o climate change taking place all over the world. And it is measured by the rise in rising in surface temperature both on land and in oceans and measured continuously as its growth is continuous.
- According to the IPCC panel the the global rise in temperature form 2.8 degree to 4.8 degrees in 21st century and the possible costs associated to this event site migration of species from these place, along with the environmental impact of mass extinction or relocation natural ecosystems such as coral reefs, mountain chains and shrinking of arctic and antarctic poles.
- Various NGOs have come up that try to mitigate this change in the evolution of natural gases, either by climatic engineering or by adaptation of habitats. NASA, UNFCCC and G77 nations have taken this step towards the prevention of climatic change.
Answer:
c. Chemical weathering
Explanation:
One of the famous landmarks in New York City is "The Statue of Liberty." It was built in<em> 1886</em> as a gift to the Americans from France.
The statue is covered with<em> copper sheets</em>, thus, it used to have a brown color. However, over time, the color turned into greenish-blue. This is because<u> the copper sheets underwent chemical weathering</u>. Such process occurred as a result of the reaction of copper with Oxygen in the air and with water. It produced<em> "copper carbonate,"</em> which is<em> greenish-blue</em> in color. Such color was noticeable in<em> </em>1900<em>, </em>but it covered the entire statue in <em>1906.</em>
A biggie: the transcontinental railroad. Because it would economically improve wherever it was, both the North and the South competed for the railroad to be in their respective territory, evidenced by the Kansas-Nebraska Act and the Gadsen Purchase and induction of California as a free state in 1860.
In addition: people could get land cheap because it was abundant and might leave to start afresh economically.
There's other stuff I can't remember as clearly, but there's a little and I hope it helps :)
