The Pros And Cons Of Active Plate Tectonism

1244 Words 5 Pages
The continuous movement of the heated substances in the planet’s interior causes tectonism to proceed, and some planets in modernity still have active tectonism, such as Mars, Earth and Venus. Planets that are miniscule are found to cool off quicker due to to the proportion of volume to area, which causes smaller planets to desist to have plate tectonics faster than larger planets. The absence or presence of tectonism on a planet circumducts around the capacity of the planet and the amount of water on the planet. The outer planetary layer is limited of heat due to the brittle deformation caused by liquids, and can further expand the knowledge on the mechanics of rocks.

Tectonism is the moving and deformity of the exterior layer of a planet

After taking photos of Venus on a spacecraft called the Magellan in 1979 (Kerr, 1992), low-resolution photo-graphs of the planet have caused researchers to determine that Venus has indeed gone through the proposition of active plate tectonics by confirmation of newly formed crust on the planet compared to the trenches of the ocean bottom on planet Earth. These images were compared to the crust of planet Earth after an emasculated submarine called GLORIA that uses sonar radiation to examine the seafloor correlated to how Magellan traced the ridges on Venus. Photographs of the plates on both Earth and Venus have been determined to angle upwards on one side while the other side curves down into the mantles of the planets, exemplifying how the plate tectonics of both planets appear to be similar. Even though the plates on Venus were thought to be thinner than the tectonic plates of planet Earth, the bulges in the plates have implied that Venus’ plates are estimated to be around 40 to 50 kilometers thick, just as on Earth (Kerr, 1992). This further demonstrates how the internal structures of Earth and Venus share similarities in how their planets manage …show more content…
The relation be-tween size and planets influence that the likeliness of plate tectonics increases with increasing planet size, usually with in-creasing density to also be a factor. Scientists such as (Heck and Tackley, 2011) agree that although the data they gathered seemed reliable and correct, further care should have been put into interpreting the values of friction coefficients and yield stresses, because the values are dependent on the overall conclusion of the tectonic behavior. Other scientists have come to conclusion that Venus and super-Earths have encountered tectonism in antiquity (Valencia et al.,
