Why is oceanic crust always subducted underneath the continental crust?
Oceanic crust subducts under continental crust because it is denser. Continental crust's density is too low for it to be forced into the mantle.
Why is oceanic crust subducted under continental crust?
Continental crust is less dense and cooler than oceanic crust and less dense and cooler than the asthenosphere, therefore instead of subducting, it is pushed upward in a collision between continents, or floats over a subducting oceanic crust.
What are the two main types of crust on earth?
Oceanic crust-made up primarily of basalt-4-5 kilometers deepContinental crust-made up of granite-low density: allows it to "float" on the much higher density mantle below-20-30 miles deep
How is the difference in density between the oceanic crust and the continental crust important?
Oceanic crust is thin, dense and composed of mainly silicon and magnessium While the Continental crust is thicker but less dense in comparism with the oceanic crust and its composed mainly of silicon and aluminium.
Granite is a low-density rock that makes up the what crust?
Granitic rock forms the majority of the continental crust.

What methamorphic rock forms at very high pressures but moderately low temperatures associated with subduction of oceanic crust and sediments?
Biotite marble

How do changes in temperature of air affect its density?
if it is high the density is high so if the temperature is low the density is low.
Is an anticyclone high pressure?
yes, anticyclones are high density and high pressure and cyclones are low density and low pressure
Granite is a low-density rock that makes up the what crust?
Granitic rock forms the majority of the continental crust.
What Granite is a low-density rock that makes up what crust?
Granitic rock forms the majority of the continental crust.
Is oceanic lithosphere lighter than continental lithosphere?
no
Why does water have low density?
Water do not have a low density.It has a comparatively high density.
What is zoning density?
How high or low the density of your city is.
