The surface area of earth is 510 ✕ 106 km2, and 71% of this is ocean. using the data from the sample exercise, calculate the average depth of the world's oceans in feet.

the average story is 10 feet and the car is below ground so it would be negative. i assume the answer would be -20 feet

sediment layers stop spreading when they reach a barrier or they run out of sedimentary material. lateral spreading is the movement of gently to steeply sloping, saturated soil deposits caused by earthquake-induced liquefaction. i hope this . : )
