There are a number of things that may happen to substances that are less dense than the surrounding material. In most cases, this is what will cause them to float on the surrounding material.

Is it true molten material in the asthenosphere rises in convection currents because heated materials become more dense?
Actually, hot, less dense material rises, and cold, denser material sinks. Denser material will be heavier (per unit volume) and gravity therefore pulls it down. Less dense material has buoyancy and rises. It's very logical.
Basketball net material is made of what?
high dense polymer fabric
What makes an object float rather than sink?
In general ... -- Density = mass divided by volume. -- If the object is less dense than the fluid surrounding it, it will float. -- If it's more dense than the fluid surrounding it, it will sink. This way of looking at it applies equally well to fish, battleships, birds, hot-air balloons, and air masses with different temperatures and densities.
Why substances have different melting points?
just because accept it ok!
Can a solid be less dense than a liquid?
Yes, there are many. For example, anything that floats on water is less dense than liquid water. A number of solids are less dense than liquids. The most common example is ice. Ice (frozen water) is less dense than its liquid counterpart for some very specific reasons. Many other solids are less dense than liquids, as well. Using water as the liquid, you'll find that cork, wood (most kinds) and styrofoam will all float on it. As the liquid becomes more dense, the range of items that will float on it increases. Mercury, for example, is a liquid metal at room temperature. Because it is so dense, many things will float on it. Lead is one example of something that will float on liquid mercury. For a question about substances that are less dense in their solid form than those same substances in their liquid form, use the link below to the related question.
What happens to the temperature and the density of the the material?
When the material gets closer to the core it gets hotter and more dense.
What happens to the temperature and density of the material in the earth?
When the material gets closer to the core it gets hotter and more dense.
Do convection currents form in the mantle when heated materials become more dense?
Yes, convection currents form in the mantle due to the heating and cooling of material, which causes density differences and drives the movement of material. When material in the mantle is heated, it becomes less dense and rises, while cooler, denser material sinks, creating a circulation pattern known as mantle convection.
Why did dense substances sinking into Earth's core heat Earth's interior?
Because of the friction created between rising and falling material.
How do hot air balloons use the principle of bouyancy?
Hot air balloons heat up contained air so that the density of it becomes significantly less than the outside air and thus the container (balloon) will rise of float in the surrounding air until the density difference is null. Buoyancy is just that, less dense substances floating or rising in more dense substances. The other approach is saying more dense substances sink in less dense substance.
Why will more dense water remain at the bottom of the cup?
The force of gravity acts to pull as much mass as possible to the lowest location possible; this happens when the denser substances or objects sink, and the less dense substances or objects rise, making room for the denser ones.
Why does sand oil and maple surup sink in water?
more dense substances sink, less dense substances float. oil will not sink in water, it will float, it is less dense.
What are three substances from most dense to least dense?
Lead, iron and water
Is an ice cube more dense or less dense than liquid water?
Less dense. For most substances, the solid form is more dense than the liquid form; water is a notable exception.Less dense.

Is magma less dense then the surrounding rock?
yes
Do plates become more dense or less dense when they become cooler?
Cooler material is more dense and hotter material is less. This means that plates become more dense as they cool.
When convection takes place in the mantle why does rock material sink and warm rock material rise?
This happens with all liquids which have varied heat through out it, in fact even in the air. This happens because when objects get hotter, they vibrate more, and thus take up more space. This means that the same mass takes up more space, meaning that the substance becomes less dense. Therefore, the hotter rock rises above the cooler rock because it vibrates more, so takes up less space, so is less dense. From there, denser substances fall to the bottom because the heavier objects can push the lighter substances out of the way, which in this case, is upwards.
