Answer: I dont understand you question
Explanation:
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 :)
Global warming impacts terrestrial biomes since it brings about <span>decreased precipitation and longer winter seasons. Global warming refers to the increase in temperature of the Earth's atmosphere. This is brought about by release of greenhouse gases (e.g. carbon dioxide, methane) in the air which trap heat in the Earth's atmosphere. As a result, there is increased variability of weather and climate patterns. </span>
Answer:
Continental drifting
Explanation:
Continental drifting talks about the movement of continents . The process was first discovered by Alfred Wegener. Alfred Wegener noticed the great similarities of the Atlantic coastline of Africa and the south America. He noticed the edge of each continents fits like a puzzle. The idea that the continents were once joined together and have split apart was born out of the observation of the similarities of the continents.
The similarities of fossil found in different continents also proved that the continental has been drifting . The similar fossils found in different continents were better explained if the continents were once joined together. Fossils like the Mesosaurus , a fresh water reptile were found in different continents.
The similarities in rock structure also proved the continents have been drifting .
Answer:
The Andes were formed by tectonic activity whereby Earth is uplifted as one plate (oceanic crust) subducts under another plate (continental crust). To get such a high mountain chain in a subduction zone setting is unusual, which adds to the importance of trying to figure out when and how it happened.
