How many tectonic plates are composed of only continental crust?
Some geologists believe there are no tectonic plates composed solely of continental crust, as plates typically consist of both continental and oceanic crust. The concept of a plate composed entirely of continental crust is not widely accepted in the field of plate tectonics.
Does Uranus have any active plate tectonics?
Uranus doesn't have any active plate tectonics. Uranus is made out of gas and does not contain any solid surfaces.
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
Does the earth's plates each contain a continental crust and an ocean crust?
yes
Why are continental plates less dense than oceanic plates kids answer?
Continental crust and continental crust are made of different types of rock. The rocks in the continental crust do not contain as many of the heavier elements as the ones in the oceanic crust do.
Is the Nazca Plate oceanic or continental?
The Oceanic plate denser than the continental plat because it contain magnesium,which is denser than aluminum found in continental plates.
Does the continental slope contain rich oil fields?
The continental slope can contain oil fields, but not always. Oil deposits form in specific geological conditions, and while some continental slopes may have rich oil reserves, others may not have significant amounts of oil. It ultimately depends on the history and characteristics of the sedimentary basins associated with that particular continental slope.
Which mountain range contains the continental divide?
The Rocky Mountains contain the continental divide, which runs along the spine of the range from Alaska to Mexico.
How do magnetic reversals provide evidence for sea-floor spreading?
The presence of magnetic domains of alternating orientation parallel to the plate boundaries.
The thick sedimentary rocks which are located off the continental margins may contain commercial quantities of?
gas and petroleum
How mountains on land can be composed of rock that contain fossils of animals that lived in ocean?
Mountains on land can be composed of rocks that contain fossils of oceanic animals through the process of plate tectonics. When tectonic plates collide, the oceanic plate may be forced beneath the continental plate in a process called subduction. The pressure and heat from this process can transform the oceanic rocks containing fossils into mountainous structures.
Which plates have continental crust?
The plates that have continental crust include the North American Plate, South American Plate, Eurasian Plate, African Plate, Australian Plate, and Antarctic Plate. These plates contain mostly granitic rock, which is characteristic of continental crust.
