Answer:
Options (A), (B), (C), and (D)
Explanation:
The volcanic activity refers to the eruption of magma at the surface of the ocean floor and continental land areas, forming volcanoes.
Some of the tectonic settings that are associated with volcanic activity are as follows-
- Mantle plumes- These are the large uprising bodies of magma that are generated due to the formation of convection current in the mantle. These are localized body and are located away from the tectonic boundaries. For example, Hawaii is formed as the plates moved over the mantle plumes.
- Continental rifts- This refers to the eruption of magma at the surface of the continents, due to the divergent motion of two continental plates. It results in the formation of a rift, rift valley and then later forms an ocean.
- Island arcs- These are formed due to the collision of two oceanic plates, where the volcanoes are formed on the lighter oceanic plate due to the rising up of magma.
- Continental arcs- These are formed due to the collision between an oceanic and a continental plate, where the volcanoes are formed due to the uprising of magma in the lighter continental plates.
Answer:
the time of the lowest temperature.
Explanation:
Relative humidity simply talks about the ratio of the quantity of water the air contains at any given time, to the highest quantity of water the air could ever have. So when the water vapor content in air remains constant while the temperature falls, then the relative humidity tends to increase. This phenomenon usually takes place in the morning when the sun is yet to come out and the temperature is usually cooler. When sun peaks, afternoon sets in, the relative humidity then reduces.
Star dunes are mountains that can form in areas with relatively sparse sand and ever-changing winds.
<h3 /><h3>Where is the star dune easiest to find?</h3>
They are easily found in deserts, and will be formed with the transport of sediment by changing the direction of strong winds.
Therefore, the dunes are ecosystems formed by fine grains of sand from the action of the winds, forming mountains and hills of different shapes.

Answer:
D.
Explanation:
Its not c, maps didn't necessarily state there was a prime meridian, so i dont think it is a, and I don't think maps were ever based around a nation, they were made to see certain areas not to put their nation in the middle.
Answer:
They were colonized by different countries. Mainly Spain, France and Portugal.
Explanation:
The reason for the large differences in demographics has to do with the fact that there were different countries that colonized the various regions.
Spain originally colonized the Caribbean,Central America and many parts of South America while Portugal colonized what is now known as Brazil.
Eventually France became involved and had control of the Caribbean and Central America for a while.
This is why there is some French and some Spanish spoken in the islands. Central America and the majority of South America still speak Spanish.
Other factors in the demographics include the native inhabitants of the regions and their appearance along with the slaves brought from countries outside of those regions.
