The crust, is the surface of the Earth; therefore on the top.
The above is true, however it is slightly more complicated than this!
Crust is formed at mid ocean ridges where magma rises to the surface as tectonic plates move apart. It is also formed (perhaps counter-intuitively) at destructive plate margins where volcanism occurs and the lava adds to the overlying crust.
Oceanic sediments build up at the boundary of the continental crust as the oceanic slab scrapes against the overlying continental crust as it subducts (this is known as an accretionary prism).

Compared to Earth's continental crust Earth's oceanic crust is?
thinner and denser
What are the two crusts found on earth?
The earth's crust is comprised of the oceanic crust and the continental crust. Bread has the crunchy and the sofy crust.
What two crusts make up the Earth's crust?
Continental crust and Oceanic crust.
What is the geothermal gradient in the Earth's continental crust?
Varies obviously, but the average geothermal gradient in the Earth's continental crust is 25 degrees Centigrade/kilometre
What compose most of Earth's continental crust?
Silicate minerals compose the crust.
What is the continental crust of the earth?
what is the continental crust
What caused the first land masses to form on earth?
Granitic crust, a.k.a continental crust, began to form, which happened to be less dense than oceanic crust. Therefore, the continental crust went on top of the oceanic, thus creating the first land mass on Earth.
What layer of the Earth's crust that is not covered by ocean water is called the crust?
continental crust
Where is the crust on earth?
In general the Earth's oceanic crust is thinner then the continental crust
This layer of the earth's crust is the thickest?
continental crust
Compared to Earth's continental crust Earth's oceanic crust is?
thinner and denser
What layer of crust averages 25 miles in thickness?
Continental crust.
Is Earth's oceanic crust thicker or the continential crust?
the Continental crust is thicker
What is the state of matter in the earth's crust?
the state of matter for the earth's crust is continental and oceanic.
Which of Earth's layers form rigid and mobile tectonic plates?
The outer layers, the continental and oceanic crust.
What are the two types of crust on the earth?
There are two types of crust, and they are the oceanic crust and the continental crust. Oceanic crust is thinner yet more dense than continental crust, and continental crust is on average older than oceanic crust :)
What are the two crusts found on earth?
The earth's crust is comprised of the oceanic crust and the continental crust. Bread has the crunchy and the sofy crust.
