Answer:
The plate boundary is a convergent one where a subduction zone is created.
Explanation:
The Andes are the longest and highest mountain chain in South America, and among the largest ones in the world as well. It is a mountain chain created because of the collision between two tectonic plates and the process is still not over, so the Andes are still growing in size and elevation.
The plates that collide are the Nazca Plate (not the Pacific as it is stated in the question) and the South American plate. The Nazca Plate is a smaller plate and it is mostly made up of oceanic crust, while the South American plate is much larger and is mostly made up of continental crust. The lower and denser Nazca plate moves below the South American plate, thus it subducts, and as it does so, the crust near the plate boundary is pushed up, creating a mountain chain, in this case, that being the Andes.
Answer:
When these forests are cut down, the plants and animals that live in the forests are destroyed, and some species are at risk of being made extinct. Further, as the large-scale harvesting of lumber from the rain forests continues, the balance of the earth's eco-system is disrupted.
Explanation: did that help? hope it does.
"A pair of scissors consists of two pivoted blades. In lower-quality scissors, the cutting edges are not particularly sharp; it is primarily the shearing<span> action between the two blades that cuts the material. In high-quality scissors, the blades can be both extremely sharp, and tension sprung - to increase the cutting and shearing tension only at the exact point where the blades meet. The hand movement (pushing with the thumb, pulling with the fingers) can add to this tension. An ideal example is in high-quality tailor's scissors or shears, which need to be able to perfectly cut (and not simply tear apart) delicate clothes such as chiffon and silk."</span>
Question 2:
<span><u>slow, steady evolution of a small isolated population</u></span><span>
This evolutionary theory suggests that a species slowly and continuously evolved over a long period of time. This selection and variation happens more gradually. It is hard to notice over a short period of time. The change is slow, constant and consistent. In punctuated equilibrium, the changes come in spurts. There are periods wherein a huge change occurs and there are also periods with very little change. The mutation is at random. Genetic drift is the change in the frequency of a gene variant due to a random sampling of organisms. </span>
