Answer:
the lower peace is portrayed ridiculously large in comparison to its actual size
Answer: c. Oxygen, silicon, and aluminium
Explanation:
The common elements in the Earth's crust in order of decreasing abundance are as follows:
Oxygen: Oxygen is the most abundant element on earth's crust. It makes up 46.6%. It exists as compound of the silicate minerals. It is used for industrial, commercial and medical purposes.
Silicon: Silicon is the second most common and abundant element on the earth crust. It makes up the concentration of 27.7%. It combines with the minerals of silica to form the silicate minerals. It is used for the purpose of ceramics, cosmetics, glass and other products.
Aluminium: Aluminium is the third most common and abundant element on the earth crust. It makes up the concentration of 8.1%. The aluminum exists in the form of aluminium oxide, potassium aluminium sulfate and aluminium hydroxide. It is used for the purpose of manufacture of rockets, machinery and automobiles.
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.
The answer is a) true
hope this helps ! :D
<span>the correct answer for this question is C - the currents responsible for powering the movement of tectonic plates are convection currents. Convection currents are those currents that occur due to a temperature exchange.</span>
