Answer:
C) They are along a plate boundary in which plates are currently converging, causing uplift and steep slopes.
Explanation:
The Andean Mountain Range is by far the longest and highest mountain range in South America, and one of the largest in the world as well. Its formation is due to the convergent plate boundary between the South American plate and the Nazca plate. The Nazca plate is an oceanic plate, while the South American plate is a continental plate. The Nazca plate subducts bellow the South American plate, causing uplift in the area near the subduction zone. This has resulted in lifting up of the land, slowly creating the steep and very high Andes. The plate boundary is still active in the same way, so the process still continues.
It lies on the Indian Ocean side of the continent, almost entirely within the Eastern Hemisphere – hence the name “East Antarctica”. The region includes the South Magnetic Pole, the Geographic South Pole, the Ross, Scotia and Weddell Seas and the Shackleton Ice Shelf.
Answer:
The most likely explanation is that the star is a member of an eclipsing binary star system.
Explanation:
An eclipsing binary star system takes place when two stars which are close to each other move in an orbit in which sometimes, one star can hide the light behind the other.
There are two types of eclipses depending on the orientation of the orbit and the size of the stars: the totals or the annular ones. It may also be the case that the eclipses are partial.
<em>Algol </em>is the best known eclipsing binary star, and the first of this kind to be discovered. Its interval between eclipses is 173 hours (2.9 days).
When this type of eclipses happens, the brightest star provides 92% of the light of the system, while the eclipsed only contributes less than 8%, and there is a third star, which is not eclipsed.
Therefore, if there is any star that has been bright most of the time, and during certain time intervals it becomes dimmer, that star is being overshadowed.
It is called a river basin
