Explain how are the boundaries established by european colonization a long-term cause of ethnic conflict in the region today.

  The boundaries set by the European colonial powers are causing a continuous ethnic conflict in the countries that were granted independence. This is due to the borders being set by the will of the European countries, and very often they include multiple ethnic groups that have a history of bad blood between them, and they are in the same territory, so there's very often use of violence.

  This has led to multiple parts of multiple countries to be controlled by paramilitary units, where people from certain ethnicity are not allowed to go, and if they do, usually end up dead.

i am a little confused myself with what goes with the letters and what goes with the numbers but ill do my best to you

the cordillera states and grand canyon are along the southwest u.s. and northern mexican pacific.

the great plains and southwest desert are also the prairie and home to many earthquakes too .

the coastal plains have poor soil and many factories started in the south.

is this what u needed? if not i can see what i can do

the climate of each region is different from one another.
