Continents float because the rock beneath them is denser then the surface rocks The surface rocks are poorer in iron than the deeper layers. The continents are made mostly of silica rich rock, which is less dense than oceanic crust, so when the two come in
contact, the oceanic crust sinks beneath the continent.
What else can I help you with?
Why do heavy things float?
Any object will float if it has less density than the liquid.
What is the name of the force that makes things that are heavy float?
a dingaling
Does Antarctica float?
Antarctica is a continent: continents do not float.
How do you explain why things sink or float to a 5 year old?
Things sink if they are heavy and push the water down, and float if they are light and let the water hold them up like a balloon.
Will egg float in water?
no because they are too heavy to float .
Why is an object too heavy on the earth can be lifted easily on the moon give reasons?
Because in space its makes things float
Why do continents float high because they are?
Continents float high because they are less dense than the underlying mantle layer of the Earth's crust. This buoyancy allows them to "float" on top of the denser mantle, similar to how ice floats on water.
How do things float?
things float because they are less denser then the water. second things do not float, the molecules from the water support the molecules from the thing on the water. that is how something heavy can float. it just has to be boyent meaning it is spread out enough so there is more water molecules to hold it up. if you mean in the air it is the same concept.
Do the seven continents float on water?
No, they float on the mantle, which is made of ultramafic rock softened by intense heat.
Did larger continents broke through the oceanic crust?
No, they float on it.
How is salt important in making heavy objects float?
dissolved salt increases the density of solution than the density of heavy metal, which help the heavy substance to float
Continents float high because they are?
Continents float high because they are made of less dense materials compared to the underlying mantle, allowing them to "float" on top of it. This is similar to how ice floats on water due to its lower density.
