Answer: True
Explanation:
Sedimentary rocks are, in average, 1800m thick, where 1m = 3.28084 ft
so 1800 meters are equivalent to 1800*3.2 ft = 5760 ft.
But this is the average, there are some areas with no sedimentary rocks at all, and some areas, like the Texas and Lousiana Gulf coasts, that have around 20,000m of sedimentary rock, and knowing that 1m = 3.2ft
20,000m is a lot more than 10,000 feet, so the statement is true.
