Divergent boundaries are when two tectonic places are moving away from each other. In the current configuration of Earth, that happens in the ocean.
When plates move away from each other, they leave a gap. That gap is filled with lava that solidifies quickly and forms now crust. If the ocean floor is relatively shallow, and the lava pressure is big enough, that can lead to the formation of new islands, mountains/volcanoes on top of the gap. That's basically how the Galapagos islands were created.
<u>It has good credit because it has large, well-managed financial reserves. This means it can borrow money at low interest rates from capital markets all over the world to then lend money to developing countries on very favorable terms.</u>
Calderas are depressions in the earth that have been made after a volcano erupts and then collapses. While Mountains could be an answer but Calderas makes more sence
Tundras and deserts have a number of similarities such as their lack of water or how organisms that inhabit them are have special features to survive their extreme weather. Both are nearly unsustainable for human life and have just like the tundra, deserts have freezing temperatures at night.
