Can oceanic crust sink?
It is denser than continental crust.
Why does the oceanic sink beneath continental crust at convergent boundaries?
The continental crust is less dense than the oceanic crust. That's the reason we find that the oceanic crust sinks (subducts) beneath the continental crust.Continental crust is less dense than oceanic crust and so cannot sink below it.
If new rocks are always forming why is the Earth not getting bigger?
The new rocks don't form from nothing. They form either from material from older rocks that were broken down, or magma that originates inside Earth. As magma rises and erupts as lava from volcanoes the crust will sink down slightly, filling in the space left behind. New oceanic crust is formed as lava erupts at mid-ocean ridges, but at the same time old oceanic crust slides down into the mantle at subduction zones.
What happen to the crust when the molten rock sink to lower mantle?

Can some of the crust sink under the ocean during an earthquake?
TRUE
What is water that doesn't sink in but runs across earths surface?
runoff
Is the earths crust hard?
Earth's crust is very hard because it is made of rock. If it wasn't hard you would sink down into the Earth's core.
How were the earth's layers formed?
To begin with the Earth was like a ball of hot bubbling liquid of rocks made from different elements and compounds. Some rocks were heavier than others. The heavy rocks started to sink and moved towards the center of the earth. Lighter rocks moved towards its surface. This separation of layers took millions of years. The present day Earth comprises the crust, the mantle and the core.
How do plants affect earths landform?
the plants roots sink into the rock and cracks the rock.
What do you call water found in cracks and pores in sand below earths surface?
A sinkhole, also known as a sink, shake hole, swallow hole, swallet, doline or cenote is a natural depression or hole in the surface topography caused by karst processes which involves the chemical dissolution of carbonate rocks.
Can oceanic crust sink?
It is denser than continental crust.
Why is the oldest oceanic crust is considerably than the oldest continental rock?
Oceanic crust is more dense than continental crust. As a result, over time, continental crust is harder to "recycle". Rocks are recycled when they are subducted and remelted. Since continental crust is harder to subduct (it wants to keep floating), it is not recycled as much as oceanic crust, which is dense and will sink and remelt.
Why does ocenaic crust sink beneath the continental crust at a subduction boundary?
The oceanic crust is denser than the continental crust.
Why does the oceanic crust sink beneath the continental crust at the subduction zone?
density
Why might molten rock rise and sink beneath the earths surface?
changes in buoyancy due to changes in density differences between the magma and surrounding rock.
Why does the oceanic sink beneath continental crust at convergent boundaries?
The continental crust is less dense than the oceanic crust. That's the reason we find that the oceanic crust sinks (subducts) beneath the continental crust.Continental crust is less dense than oceanic crust and so cannot sink below it.
