The statement is - True.
After the discovery of the oil reserves in the Middle East, the more powerful countries of Europe started to intensify their interest about the region a lot.
Until the oil reserves were discovered, the Middle East was not a zone of interest for the super powers of the European continent, so the region was kind of of put aside. But than, the oil reserves were discovered, and just that, but it turned out that they are enormous, the biggest in the world, and that changed the way the Middle East was looked at.
After the oil reserves were discovered and started to be exploited, all of the stronger and more influential countries had their focus on this region, and they still have it.
ITS B because the temp changes so it becomes cold
I think the one that can impact the climate of an area based on its geographical relief would be : B. Elevation
Mountain exist in a higher elevation lands and ocean exist on the lower elevation. The areas in higher elevation tend to have lower temperature compared to those in lower elevation
hope this helps
Answer:
a) Yes! the American chestnut tree is a native species. The American chestnut tree was present before the Europeans arrived in North America in the 1600s. Since a native species has been defined as any species that was present in North America before the arrival of the Europeans, then it is a fact that the North American chestnut tree is a native species.
b) The chestnut blight is an invasive species that is native to east East Asia, and was accidentally introduced into North America around the early 1900s, when the Japanese chestnut was commercially cultivated in the United States.
c) Invasive species tend to proliferate at a very high rate because they lack some natural constraints in the new environment such as natural predators, competition, and as in the case of this chestnut blight; the host has no natural defense mechanism against them. These conditions allow them thrive more than they would in their natural environment, unchecked
d) Yes, I agree with this idea, albeit to some extent. The development of hybrid chestnut resistant to the chestnut blight will possibly return the forests back to how it was before the Europeans arrived in the 1600s, but the genetic conservation will be altered, since these new trees will be an hybrid of the old trees, and the forest won't truly be as it was before the 1600s
