When you take a cake out of the oven, it slowly cools. Plate tectonics requires more than a molten core.
It requires a core which is hot enough to produce convection currents.
B. Indeed, the pattern of faults on Venus suggests that plate-tectonics-like movement struggled to begin but never quite succeeded. Mars is a smaller planet than Earth; it has cooled more, much like a small glass of hot water would cool faster than a … But Venus has no evidence of plate tectonics, so this theory states that the interior of the planet heats up (due to the decay of radioactive elements) until material … Update: So water is like a lubricant? These plates can also cause sudden destructive earthquakes that reshape entire regions.
Answer to: Does Mercury have plate tectonics? Answer Save.
Mercury is just no longer tectonically active, "...Each planet has a unique history and unique tectonic features.
Large planets, such as Venus, Earth, and Mars, are large enough to have remained hot inside and still have active tectonism. comments. However, it does not have global tectonics as there is on Earth—plate tectonics. Curiously, though, some of the moons of Jupiter and Saturn appear to exhibit tectonic features. To have true plate tectonics, you need to have subduction zones so that one plate can ride over the other.
Favorite Answer. These currents cause the plates … Mercury Is Tectonically Active, Making It Uniquely Like Earth A whole new picture of Mercury’s geologic history emerges, showing its crust is being thrust up and its surface is changing over time Why doesnt Mercury have plate tectonics? To have true plate tectonics, you need to have subduction zones so that one plate can ride over the other. Does Mercury Have Plate Tectonics?. While their surfaces show evidence of recent deformation — tectonism — neither planet has plate tectonic activity because neither planet has a surface divided into plates. Does mercury have plate movements? Asked in Plate Tectonics, Geology Where can the result of plate movements be seen at?
6. Heat! Plate tectonic motion causes some of the most spectacular geological events you may never see. Images obtained by NASA’s MESSENGER spacecraft reveal previously undetected small fault scarps— cliff-like landforms that resemble stair steps.
By signing up, you'll get thousands of step-by-step solutions to your homework questions.
by Gemma Lavender, 27 September 2016 New imagery shows geologic features that indicate the tiny planet is still contracting today, joining Earth as a tectonically active planet in our Solar System. Through time, they have cooled. Why does Earth have plate tectonics?
Venus, which does not have tectonics, shows the results: an atmosphere that is 96 percent carbon dioxide.
D) They were produced by the stress of a large upwelling on one side of the planet that produced a bulge with canyons and cliffs. Related Questions .
Timothy. The Jovian planets consist mostly of gas, so they cannot possibly have a rigid lithosphere.
8 years ago. New NASA-funded research suggests that Mercury is contracting even today, joining Earth as a tectonically active planet. B) They were produced when the interior cooled and the entire planet shrank. Transform boundaries usually do not have volcanos, but they are marked by severe earthquakes.
Thomas Watters is a senior scientist at the National Air and Space Museum in Washington, D.C. Planetary tectonics are one of his research interests. Venus does have tectonic activity: faults, folds, volcanoes, mountains, and rift valleys. It has a molten core the same as Earth does so why isnt there any plate tectonics?
2 Answers. The planet Mercury, which is much smaller than the Earth, doesn’t have tectonic plates (plural)—it has one tectonic plate. Mercury found to have active plate tectonics. C) They were produced by plate tectonics, much like cliffs on Earth.
This is thought to be due to the fact that Venus is hot and dry. This means Mercury's surface cannot undergo plate tectonics as we know them. The theory of plate tectonics is based on a broad synthesis of geologic and geophysical data.
In an email, he says that while Earth has at least 15 moving plates, all the evidence suggests Mercury is a one-plate planet.. This happens on Earth, but not on Venus. Wiki User 2011-05-07 16:34:27. Because Mercury DID have plate tectonics. A) The cliffs are rims of large impact basins. Why does Mercury have large cliffs?
Earth, and the other terrestrial planets, started out very hot.
No. Continents, for example, drift slowly apart because the plates that form the Earth's crust move. It's toxic. Without plate tectonics, carbon would build up in the atmosphere.
It is now almost universally accepted, and its adoption represents a true scientific revolution, analogous in its consequences to quantum mechanics in physics or the discovery of the genetic code in biology. This happens on Earth, but not on Venus.
