Name the following <br><br>he valve presents at the mouth of the pulmonary artery​
trapecia [35]

Explanation:

The pulmonary valve (sometimes referred to as the pulmonic valve) is a valve of the heart that lies between the right ventricle and the pulmonary artery and has three cusps. It is one of the four valves of the heart and one of the two semilunar valves, the other being the aortic valve. Similar to the aortic valve, the pulmonary valve opens in ventricular systole, when the pressure in the right ventricle rises above the pressure in the pulmonary artery. At the end of ventricular systole, when the pressure in the right ventricle falls rapidly, the pressure in the pulmonary artery will close the pulmonary valve.

The map shows an island arc in Alaska named the Aleutian Arc. What does the arc suggest about its surrounding geographic region?
nexus9112 [7]
We see that this is a region near the continents, so it is probable that there is the boundary of a tectonic plates around there. Since there are islands there, it is quite probable that there is a subduction zone near them which means that the oceanic crust is going below the continental one and the continental is slowly elevated. This also shows that the boundary is convergent, since transform boundaries do not lead to elevation. Near convergent boundaries, there are frequently volcanoes and shallow earthquakes. Finally, the climate near Alaska is cold and this does not depend on whether islands are near a boundary or not. So, 2 4 and 5 are correct.
