It doesn't. That only happens with a small amount of oil dropped onto a quiet body of water.
Wind, waves, currents, forces on the oil and/or the water all cause other shapes.
But if all is quiet, then you get a circle because the surface tensions of both the water and the oil act to form the most "efficient" shape.
What else can I help you with?
What is the shape of a drop of oil placed in the surface of water?
A drop of oil placed on the surface of water will typically form a near-perfect circle due to surface tension forces that minimize the surface area of the liquid.
Will the shape of a drop of water and a drop of isopropyl alcohol on a piece of wax paper be the same or different?
The shape of a drop of water and a drop of isopropyl alcohol on wax paper will likely be different due to differences in surface tension and polarity between the two liquids. Water typically forms a more rounded shape with a higher contact angle, while isopropyl alcohol spreads out more easily due to its lower surface tension.
Why does a drop of water stay in a circle when you put water on a surface?
because of its molecular structure. hey wanna go out with me? i can show you my molecular structure!
How can you capture the perfect moment of a water drop splash in a photograph?
To capture the perfect moment of a water drop splash in a photograph, use a fast shutter speed to freeze the motion of the drop as it hits the water surface. Adjust the lighting to highlight the details of the splash and use a macro lens to capture the intricate patterns created by the water droplets. Experiment with different angles and compositions to create a visually striking image.
Why the drop of water is always circular in shape?
Surface tension ; see relevant link .
Why would it be very difficult to drop a note in a bottle off of a boat into the waves and have it reach shore?
the bottle will move with the water in a circle
Why do water droplets always form one huge drop on a penny?
Surface tension of water draws it into a larger drop. It will do that on any nonporous surface- metal, glass, smooth plastic, etc.
How do you make the perfect water balloon?
to make the perfect water balloon, simply use a regular water balloon rather than a water balloon. regular water balloons can get as big as a human head. the down side is they don't pop easily. you can drop them on the floor and they wont pop.
What monster on perfect world drop legendary weapon?
No monsters drop legendary weapons, you have to make them from molds.
When was A Drop of Water created?
A Drop of Water was created in 1987.
How do you drop goal in rugby league ps2?

What shape looks like a tear drop?
A circle with a triangle at the top
