according to the map above, which of the following statements about tornado frequency in oklahoma is true?
a. all oklahoma counties are equally at risk for tornado activity.
b. oklahoma has received more tornadoes since 1950 than in the previous 50 years.
c. no oklahoma county has had more than 100 tornadoes since 1950.
d. every county in oklahoma has had at least 10 tornadoes since 1950.

Explanation:

• Analyze each option based on the map. The map shows different counties with varying numbers of tornadoes since 1950. Option a is incorrect as colors vary by county indicating unequal risk. Option b has no information about tornado numbers before 1950. Option c - the map doesn't give exact numbers above 91 so we can't be sure no county has had over 100. Option d is correct as the lowest - range on the map is 11 - 20, meaning every county has had at least 10 tornadoes since 1950.

Answer:

d. Every county in Oklahoma has had at least 10 tornadoes since 1950.
