In young mountainous regions the continental crust is .?
thicker
As the geology officer on an expedition to a newly discovered Earth like planet you must determine where to locate the first permanent settlement This planet has volcanoes and appears to have a crust?
apex!! a young mountain range along a continental coast. --------------------------------------------------------------------------------------------------- a chain of volcanoes parallel to a continental coast. :)
How would the age of the oldest rock on the continents compare with the age of the oldest rock on the seafloor?
The sea floor is young (the rocks are made at the mid oceanic ridges and spread out form there) while most of the continental rocks are older. This is because the continental crust floats on top of the oceanic crust and is therefore not recycled.
What is the main difference between continental plates and oceanic plates?
Oceanic crust is created on Mid ocean ridges and of basaltic composition. Oceanic crust is on average comparatively young as it is subducted into the mantle in subduction zones. Oceanic crust is denser and thinner than average continental crust.The composition and age distribution of continental crust is much more complicated than that of oceanic crust. It is on average less dense and much thicker than oceanic crust and its composition is roughly that of a tonalite (something similar to a granite but with less alkali feldspar). Apart from igneous rocks and metamorphic rocks, the sedimentary rocks add a lot to the variety of lithologies found on the continents (carbonates, evaporites, sandstones, shales, conglomerates, etc.).As opposed to oceanic crust, continental crust is not subducted into the mantle in large quantities but has been gradually accumulating over geologic timescales.
What is the difference between oceanic plate and continential plate?
Oceanic plates are young and made of basalt and recent sediments. Continental plates are old and contain continental crust made of old rocks and they are usually considerably thicker than the oceanic plates

Which area of Earth's crust is thickest?
Continental crust beneath a tall, young mountain
Is the oceanic crust a thick layer?
Continental plates are thicker and of lower density than oceanic plates. They float like giant rock icebergs deeply embedded in the upper part of the mantle, while oceanic plates form more of a surface skin on the top of the mantle.
How is the oceanic crust recycled?
Convection in the mantle helps to recycle the oceaniccrust, not all of Earth's crust. There are two different parts to the crust. Oceanic and Continental. The Oceanic gets recycled, so when Scientists measure the age of the rocks, they're young.

Why are the continents old and the seabeds are young?
Oceanic crust is constantly being recycled by subduction into the mantle at convergent plate zones and creation at mid-ocean ridges. Continental crust is not subducted, therefore its old age.

What are the young fold mountain ranges?
The fold mountains that formed less than about 25 million years back are considered young . These regions may be prone to Earthquakes and volcanic eruptions because the crust of the Earth is unstable
Oceanic crust is recycled where?
The recycling center would be at subduction zones associated with areas of plate collisions, where older, colder, more dense oceanic crust is being drawn into the asthenosphere, the uppermost layer of the mantle.
