Why is eastern region climate milder than Western region climate of Nepal

Due to the geographic location along the equator, and Greenwich meridian

The climate of the West is semi-arid, yet parts of the region get high amounts of rain or snow. Other parts are true desert which receive less than 5 inches (130 mm) of rain per year. The climate is unstable, as areas that are normally wet can be very dry for years and vice versa.

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
