Answer:
Most major rivers in Southeast Asia seem to flow in the same direction. By studying the physical geography of this region, we can tell that these rivers flow from north to south because the major mountain ranges run from north to south. The rivers formed naturally between them in valleys.
A continental volcanic arc created due to the subduction of the Nazca Plate beneath the South American Plate has lead to the formation of the Andes mountains and Cotopaxi Volcano.
Option B
<u>Explanation</u>:
Mountains and volcano are mainly created due to the movement of plate depending on type of plate when plates of converging nature the for folds which make them create mountainous topography or during subduction zone where the Andes mountain Cotopaxi volcano was created their reason for their formation was the movement of Nazca plate beneath the American plate which led to the mountainous formation along the volcanic formation. The movement in plates can really make all the difference in topography and that’s how all the mountains are formed by it Himalaya or any other mountain.
Answer:
1. giant impact forms moon
2. end of heavy bombardment
3. early life (based on fossil evidence))
4. oxygen buildup in atmosphere
5. earliest mammals
6. dinosaurs go extinct
7. earliest humans
Explanation:
The Earth has a very interesting past, with lot of changes and turnarounds in it. If we sum it up quickly, we can say that soon after the Earth formed and collided with another large space object, part of the Earth was torn away, which eventually formed the moon. The Earth was constantly bombarded by meteorites and asteroids, but that came to an end as the atmosphere was becoming denser and denser. The first life started to develop in the oceans in the form of cyanobacteria, which used photosynthesis, and were constantly releasing oxygen, building it up int he atmosphere. The oxygen changed the living conditions, enabling the life to thrive and diversify. The dinosaurs and mammals eventually came on the scene, with the dinosaurs coming first by around 20 million years, giving them the edge to become the dominant life form. The mammals lived in the shadows until the dinosaurs existed, but their reign ended with a large meteorite collision. This prompted the quick evolution and diversification of the mammals, quickly becoming the dominant life form, and just few million years ago they gave rise to the earliest human ancestors, the hominids.
Cost- benefit analysis is the method that is mostly used by businessman to see whether they have taken correct decision or not.
Explanation:
Suppose a doctor has suggested two same type of medicine to the patient. One of the medicine is expensive and the other medicine is less expensive. But both the medicine will have same utility that is both will be used as a preventive measure for the sickness. One extra quality that the expensive medicine is having is that it will provide the patient to access to more application.
Using the cost benefit analysis it will be beneficial if the patient go for the cheaper medicine because the main aim of the patient is to cure the disease. Extra application is not required. The cheaper medicine will be budget friendly as well.
The cost-benefit analysis is basically known as the evaluation method because it helps the company to identify the best possible option that will give a good return on investment.
