Answer:
True
Explanation:
The Cordilleras have one major factor that distinguishes them from the other mountain ranges, the three phases of its orogeny. Unlike most of the mountains in the world that have been created by a single orogenic process, that is not the case with the Cordilleras. There have been three consecutive orogenies, the Nevadan, Sevier, and Laramide orogenic process that created the Cordilleras, thus making them a unique mountain range.
The correct answer is - With full, red line.
The circum-pacific belt is represented with a full red line. The line marks all of the belt uninterruptedly, starting from New Zealand, through the islands of Southeast Asia, along the coast of East Asia, bellow the Bering Strait, and along the western coasts of North and South America, ending at Patagonia.
This line, roughly represents the tectonic plate boundaries of the Pacific plate with the other plates with which it is in contact, or rather getting submerged bellow them. Because the plate boundaries are convergent, with the Pacific plate submerging bellow the others, there's intense geologic activity, manifested through earthquakes, volcanic activity, tsunamis.
The term is upwelling that is the answer to your question.
A net population decline resulting from an "excess of deaths over births".
Option: A
<u>Explanation</u>:
Demographic transition is a shift from higher to lower level of fertility and mortality.Rapid development in industrialization and urbanization in 
century resulted into enormous population growth. But decline in early 
century covered many reasons like consequences of two calamitous wars, where Europe suffered large population declination due to battle death and civilian causalities in World War I and II. Hence the acceleration of population growth in 19th century but downfall in 20th is also considered as balance.
