Pacific mountain system, series of mountain ranges that stretches along the Pacific Ocean coast of North America from northern British Columbia (Canada) to northwestern Mexico. They run for some 4,500 miles (7,250 km) in the United States and extend northward into Canada for another 1,000 miles (1,600 km).
Answer:
An effect of the Peloponnese war was that Macedonia invaded Greece.
Explanation:
The Peloponnese war was a war between Sparta and Athens, with Sparta coming out as a victor in it. The lack of political absence of Athens for some time in the region because of the engagement in the war with Sparta gave opportunity the Macedonians to be able to speed up their progress, implement reforms, and rapidly become a force to be reckoned with.
The Macedonians managed to reform their army and strengthen their economy, and for the Hellenic city-states, this was not a good sign. Phillip II of Macedon attacked the Hellenic city-states and defeated them all, causing a huge loss in military personnel. One city-state that saved itself was Sparta, and there are two reasons for it, one is that they were in good relations with the Macedonians and often allied, and the other because it was of interest to any of the two sides to go in war against each other and suffer losses unnecesarilly.
The idea of global cooling gained popularity about during the 1970s, <span>“There are ominous signs that the earth’s weather patterns have begun to change dramatically,” </span>Newsweek reported in 1975. At the time the highly influential source convinced <span>“drastic decline in food production.”, at that time climate scientists were convinced that a ice age was coming. Global temperatures falling between 1940 to 1975 drove the concern of global cooling, little did they know it was only a temporary fall of temperature.
That's as much as I know, hope it helped! :)</span>
It is igneous rock. When magma cools, it solidifies into a rock called an igneous rock. They are formed when the hot, molten rock rises to the surface, it undergoes changes in temperature and pressure that causes it to cool, solidify and crystalize. Hope this helped you :)!
Answer:
1.422
N/m²
Explanation:
pressure (P) = ρ g h
where ρ= density of continental crust
g= acceleration due to gravity
h is the depth given
density of continental crust is equal to 2.9 g/cm³
= 
g=9.81 m/s²
height = 50,000 m
now,
pressure (P) = ρ g h
pressure (P) =
=1.422 N/m²
