because pebbles are round they don't have pointy edge.

there are crabs in the sand of the see

Answer 2

Answer:

Walking on pebbles with bare feet doesn't hurt as much when you enter the sea because the contact area is smaller in pebbles and the pressure is high.

Explanation:

We know that,

• Pressure = Force/Area.

        that is, force is inversely proportional to area.

• Therefore, for the same amount of force on pebbles (like sand), pressure is high. This is because the contact of area is smaller.

• The upthrust of sea water on our feet reduces the force applied on the pebbles, resulting in less pain.

• Walking barefoot on stones can also be beneficial for better health, like less tension and lower blood pressure.
