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.

lord [1]

Answer:

Some areas of the Everglades have dried up.

Explanation:

These changes have caused some areas of the Everglades to have dried up. The everglades were known as the wetlands due to the massive flooding that occurred often but these canals made it so that water would not flow into some of the areas in the Wetlands. Therefore, since water never reached these areas they quickly began drying up and making the ground infertile due to the lack of water which the plants need to survive.
