The H-R diagram is a comparison between: O A star's size and distance from the Sun
O Astar's static levels and its brightness
O Astar's life span and its size
O Astar's absolute magnitude and temperature

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

so whats the answer? ?

none of the above because millions of people die in a year(also depends on where you live)
