Is it true that the deeper a rock is buried in the crust the less pressure there is on that rock?

No. The deeper a rock is buried, the more pressure it is under.

Compared to the oceanic crust the continental crust is?
less dense and more felsic
Why would a certain thickness of continental crust displace less of the mantle than the same thickness of oceanic crust?
Because its less dense
How do temperature and pressure change with increasing depth in the earth?
They both increase because there is more matter pressing down on you and as you reach the inner core it gets hotter because the core is the hottest part of the Earth. When in the center of the earth, there is less and less air from the top of the earth. in the very center there is none. All of that nothingness of simple dirt in the core makes it very hard to not be heated and pressurized.
Which type of crust is thicker oceanic crust or continental crust?
I think it is the continental crust
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.
Is it true that deeper the rock is buried there is less pressure in the rock?
It matters in the middle of the lies the core which would make it hard to pressurize and heat
As ocean depth increases?
As wer gets deeper there is less oxygen and it gets colder.
Why would the pressure decrease from the core to the crust of Earth?
There is less weight pressing down from above as the distance toward the surface decreases.
Why does oceanic crust melt?
At mid-ocean ridges, such as the Atlantic Rise and Pacific Rise. As two plates move apart the crust is stretched and thinned, causing less pressure on the mantle immediately below. Due to this drop in pressure the mantle undergoes "decompressional melting" allowing magma to form. This magma is less dense than the surrounding mantle and rises at the mid-ocean ridges, cooling and forming new oceanic crust.
Why does the continental crust float higher on the athenosphere than oceanic crust?
The continental crust is less dense
What is happens to visibility the deeper you go in the ocean?
just alot of pressure but it would be pitch black down there that's why there are some fish with lights on them. !!!! watch finding nemo It gets worse, and becomes darker because less sunlight can penetrate the deeper you go.
Why is air pressure low on top Mount Everest?
Because the higher you go, the less amount of air is it above you, pushing down. Just like water pressure is no big deal at the Surface, but gets bigger the deeper you dive.
Compared to the oceanic crust the continental crust is?
less dense and more felsic
The mantle has less aluminum and less than the crust does.?
silicon
The mantle has less aluminum and less what than the crust does?
silicon
Why does magma in the mantle rise through the crust above it?
magma comes from the outer core and when an earthquake or something happends, a crack froms and the pressure of lava shoots up like a geyser.
What causes a magma chamber to rise?
Magma rises through the crust because it is less dense than the surrounding rock, and due to the enormous pressure inside the earth.
