A Continental Craton Is Best Described as

1 continental crust is more bouyant than oceanic crust by virtue of composition hence continental crust is more difficult to subduct in the oceanic trenches. These zones have important consequences and geological features and if the rifting is successful lead to the formation of new ocean basins.

Its lithosphere that puts the plates into plate tectonics its a rigid layer on the earths surface as opposed to the hot flowing mantle that lies beneath the asthenosphere.

. The term craton is used to distinguish the stable portion of the continental crust from regions that are more geologically active and unstable. -3800 m -12470 ft. New continental crust is formed essentially in the same many as oceanic.

A craton is the oldest part of a continental plate. An earthquake is best described as. The distance from the spreading center to a trench is the lifespan of oceanic crust In a given ocean basin.

A craton is a stable part of the continental lithosphere which has survived several cycles responsible for the merge and the dislocation of supercontinents. Cratons can be described as shields in which the basement rock crops out at the surface and platforms in which the basement is overlaid by sediments and sedimentary rock. Large basin-shaped depressions that form when summit materials on a volcanic mountain collapse inward after an eruption or loss of magma are known as.

Eroding away of surface material to expose a craton continental shield. The Zimbabwe Craton is an area in Southern Africa of ancient continental crust being a part of the ancient continent of Western Gondwana with rocks dating back to the early Archean Eon possibly as early as 346 billion years ago Ga. Stable continental crust is an end product of intense magmatic tectonic and metamorphic reworking.

The term craton is used to distinguish the stable portion of the continental crust from regions that are more geologically active and unstable. A craton is a stable part of the continental lithosphere which has survived several cycles responsible for the merge and the dislocation of supercontinents. Continental crust is the upper portion of continental lithosphere.

Continental Volcanic Arc Hot Craton Ocean Basin Spot Mafic Divergent Convergent 1Chert is a key rock that tells us about the history of rocks typically found around San Francisco. A craton is a stable part of the continental lithosphere which has survived several cycles responsible for the merge and the dislocation of supercontinents. A Continental rift is the belt or zone of the continental lithosphere where the extensional deformation rifting is occurring.

Hence cratons consist of. 2 new oceanic crust is being created at the oceanic spreading centers. The formation of continental crust involves the entire sequence of seafloor spreading subduction remelting of oceanic crust and subsequent rise of the remelted material.

The oldest continental rocks are found in cratons. This answer has been confirmed as correct and helpful. The yellow and green shows material added accreted to the western edge of North America during the past 200 million years.

A continental craton is best described as A The product of active folding and faulting B The surface accumulation of molten rock C The inactive remains of ancient tectonic activity D A landform undergoing constant tectonic activity. A general thinning of the crust. What is an example of a continental rift.

Cratons can be described as shields in which the basement rock crops out at the surface and platforms in which the basement is overlaid by sediments and sedimentary rock. After surviving cycles of merging and rifting of continents cratons are usually found in the interiors of tectonic plates. According to the web pages provided above where did the chert form.

The North American Craton refers to the continent that existed prior to that time. ˈkreɪtɒn ˈkrætɒn or ˈkreɪtən123 from Greek. κράτος kratos strength is an old and stable part of the continental lithosphere where the lithosphere consists of the Earths two topmost layers the crust and the uppermost mantle.

The average elevation of the depth of the oceans is graph shows ocean hitting continental land with a depth graph True. 1 The craton is named after the country of Zimbabwe where the majority of the craton is. The general term for a mountain building episode that thickens continental crust An earthquake is best described as the sharp release of energy in the Earths crust that creates seismic waves.

A craton is a large coherent domain of Earths continental crust that has attained and maintained long-term stability having undergone little internal deformation except perhaps near its margins due to interaction with neighbouring terranes. Cratons are therefore always found within continents. The term craton is used to distinguish the stable portion of the continental crust from regions that are more geologically active and unstable.

It is an old and stable part of the continental lithosphere. Cratons are therefore always found within continents. Cratons can be described as shields in which the basement rock crops out at the surface and platforms in which the basement is overlaid by sediments and sedimentary rock.

A general term for a mountain-building episode that thickens continental crust. They are composed of ancient crystalline basement rock which may be covered by younger sedimentary rock.
