Which movement of the Earths crust implies that the continental crust is less dense than the oceanic crust?
Plate tectonic movement and subduction zones.
Which portion of earths crust is more dense. oceanic or continental?
Oceanic
What theory explains the processes that shape the Earths surface into mountains deep sea trenches and oceanic ridges?
the theory of sea floor spreading or continental drift
What is the thickness in miles of the earths crust?
Oceanic and continental combined is approximately 25 miles.
What are plates within earths crust?
Tectonic plates which may be either oceanic or continental in nature.
Compared to earths continental crust earths oceanic crust is?
Earth's oceanic crust is thinner, denser, and younger than Earth's continental crust. It is primarily composed of basaltic rock, whereas continental crust is made up of less dense granitic rock. Oceanic crust is constantly being formed at mid-ocean ridges and destroyed at subduction zones.
What portion of the earths crust is more dense oceanic or contenintal?
Oceanic crust is denser than continental crust. Oceanic crust has a density of about 3 g/cm^3, while continental crust has a lower density of about 2.7 g/cm^3.
What makes up a typical plate that moves across the earths surface?
a section of both continental and oceanic lithosphere
What makes up a typical plate that moves across earths surface?
a section of both continental and oceanic lithosphere
What is the largest layer of earths surface?
The largest layer of Earth's surface is the crust, which is divided into oceanic and continental crust. The continental crust is thicker and less dense than the oceanic crust, covering about 40% of the Earth's surface.
Why does water float on Earth's surface?
Oceanic crust is denser than continental crust, it floats lower in earths mantle.
What is tactonic plates?
PLATE TECTONICS is the study of the movement of the earths continental plates
