Crude oil is less dense than water. This is apparent after oil tanker accidents where the oil floats on the surface of the ocean.

In fact, most oil is less dense than water (ever seen salad dressing that's separated? It's split into it's oil and water components!)

Examples of buoyancy?
An egg floating in salt water. The salt makes the water more dense. Since the egg is less dense it floats!
What forms when more dense seawater sinks under less dense seawater?
Density current
Where would you find the lowest density in seawater?
Answer 1) At the Surface. Answer 2) I disagree with the above answer. For practical purposes water is not compressible. Therefore the density is the same all over. The difference in density at the surface and at the bottom is so small that it is negligible. However, fresh water is less dense than seawater, since the salts dissolved in the seawater makes it more dense. For that reason, if you consider seawater near the mouth of a river, that water will be less dense than the seawater in general.
How does the density of seawater vary with changes in temperature?
As seawalter gets colder it becomes more dense, so cold sea water is more dense than warmer water.
What is the comparative and superlative form for the word crispy?
Comparative: More crude Superlative: Most crude 'Cruder' and 'crudest' are perfectly acceptable, and indeed more idiomatic than 'more crude' and 'most crude'.
Is ice less dense or more dense than water?
no
Is water less or more dense than water?
Ice is less dense than water
Is chlorine less dense or more dense than water?
more dense
How can you determine whether solid object is more dense or less dense than water?
If more dense, it will sink when put into water; if less dense it floats.
How call you tell if a substance is more or less dense then water?
if it sinks its more dense if it floats its less dense
Is very salty water more or less dense than more dense?
More Dense.
Is the earth less dense or more dense than water?
Earth is more dense.
Is water more or less dense than gasoline?
More dense.
Is a ice cube more or less dense than liquid water?
Ice cubes are less dense than liquid water, which is why they float.
Is zinc less or more dense than water?
zinc is more dense than water
Is chalk less dense than salty water?
No, it is more dense. If it were less dense it would float.
How can you determine weather a solid substance is more dense or less dence than water?
put them both in a tub of water and if one floats its not as dense as the other if it sinks its more dense
