To determine the difference in height between the highest and lowest points in Alabama, you simply subtract the elevation of the lowest point from the elevation of the highest point.
Highest point: 2,400 feet
Lowest point: 500 feet
To find the difference:
2,400 feet - 500 feet = 1,900 feet
Therefore, the highest point in Alabama is 1,900 feet higher than the lowest point.
