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.
Greenhouse effect, Latitude, heat transport in the biosphere.
Answer:
The current amount of the Potassium-40 sample is approximately 37.521 grams.
Explanation:
The amount of the sample of the radioactive isotope decays exponentially in time, the amount of mass of the sample as a function of time (
), in grams, is described below:
(1)
Where:
- Initial mass, in grams.
- Time, in years.
- Time constant, in years.
The time constant can be found from half life (
), in years, described in statement:
(2)
If we know that 
, 
and 
, then the current amount of the sample is:
The current amount of the Potassium-40 sample is approximately 37.521 grams.
