a. caymen islands
c. australia
b. florida keys
d. hawaiin islands

The correct answer is D. An example of a place formed by hot-spot volcanoes are the Hawaiian Islands.

Explanation:

The Hawaiian Islands form an archipelago of nineteen islands and atolls, plus other small barren islands, reefs and sand banks, in an alignment of the northwest to south-east along 2,400 km in the north Pacific.  

The islands of the archipelago are the peaks that stand out from a large underwater mountain range formed by volcanic activity. Located approximately 3,000 km from the nearest continent, America, it is the most isolated archipelago on Earth.

This archipelago developed when the Pacific plate moved slowly north-west on a hot spot in the Earth's mantle at a speed of about 51 km every million years. This is why, as they are more exposed to erosion, the islets of the north-west end of the archipelago are older and generally smaller.

Almost all the magma of the hot spot is composed of gleam and so the volcanoes of Hawaii consist almost exclusively of this igneous rock.

On the islands of Hawaii there are many earthquakes, generally caused by volcanic activity. The islands are also prone to tsunamis caused by earthquakes that occur in relatively distant locations in the Pacific.

from almost the creation of the first true maps of the earth, people started seeing how continents would be able to fit together.   in particular, people noticed that south america fits almost exactly into africa.

you should be aware that while world maps were around early in the 1600’s and better defined by the end of the 1700’s, those maps were not ‘public’ but were treated as state secrets.   and so it was not till much later that the broader ‘science’ community had access to good quality and accurate world maps.

get the whole story here…

it is now known that most of the major continental masses can be fit together in a jigsaw process.   in fact we now know that the continents were indeed once all joined together as one land mass – the supercontinent of pangaea.

if you look at most world maps you will ponder how this is evidence, as the continents really don’t appear to ‘fit’ together very well.   what you need to understand is that the vast majority of maps are drawn using a map projection that has the north and south poles (which are points) are a line the width of the map at the top and bottom.   this means that the map distorts the true shape of the earth’s land and oceans as you love closer to the poles.     some other map projections distort less, but have the map shape looking like segments of an orange.   see here for a range of map projections.   check out the way greenland changes size in each!

what is more remarkable, is the next piece of evidence when added to the shape of continents.

location of mountains and fossils

what is remarkable, when you reassemble all the continents together, the ancient mountain ranges (many now eroded to their cores) and the location of rock types and fossils all match up.
