Answer: The correct option is D: Is alloyed with carbon and chromium to make stainless steel.
Explanation: Because of its physical characteristics, iron is a material that tends to oxidize easily. With the chromium alloy stainless steel is created, which for its quality can be used in the manufacture of structural steels.
The answer is b an astronomical unit
<span>Nasal conchae and meatuses Nasal conchae, also known as nasal turbinates, are curved shelves of spongy bones forming in the walls of human nose. The nasal conchae function is to regulate the airflow through the nasal passages to provide rapid warming and humidifies air as it passes to the lungs. The nasal conchae divides the nasal cavity into ducts or meatuses, this are <span>the passages in the nasal cavity formed by the projections of the nasal conchae.</span></span>
<em>The convergence between a continental plate and an oceanic plate</em><em> is subduction process where the denser oceanic plate force the </em><em>thinner continental plate to sink into the mantle.</em>
<u>Answer:</u><em> Option (D)</em>
<u>Explanation:</u>
The<em> type of volcanism formed the Andean Mountains in South America</em> is due to subduction process. It is due to the converging of Nazca Plate over Antarctic Plate due to gravity and made them to sink below the <em>South American Plate. </em>
This process still continues today and due to the activity, it causes volcanic eruptions and earthquakes in that region. It was reported about <em>150 - 160 (approx.) active volcanoes in the Volcanic Belt of Andes.</em>
The amount of time it takes Earth to rotate on once on its axis would be 24 hours.
