Let’s discuss the question: how does seafloor crust differ from continental crust. We summarize all relevant answers in section Q&A of website Linksofstrathaven.com in category: Blog Finance. See more related questions in the comments below.
How does it explain the differences between seafloor and continental crust?
Seafloor crust is thinner, younger, and higher in density. … Continental crust is made from volcanic rock called basalt, which is lower in density than what the seafloor crust is made from.
What is continental crust and oceanic crust?
It is the solid rock layer upon which we live. It is either continental or oceanic. Continental crust is typically 30-50 km thick, whilst oceanic crust is only 5-10 km thick. Oceanic crust is denser, can be subducted and is constantly being destroyed and replaced at plate boundaries.

Why is continental crust lower intensity the seafloor crust?
Why is Earth’s continental crust lower in density than seafloor crust? Continental crust is made as the lowest-density seafloor crust melts and erupts to the surface near subduction zones. … Seafloor crust is younger than continental crust, so it has had less time in which to suffer impacts.
Why is continental crust lower in density than seafloor crust quizlet?
Why is continental crust lower in density than seafloor crust? Continental crust is made from remelted seafloor crust and therefore only the lower-density material rises to form it. How fast do plates move on Earth? one plate slides under another, returning older crust to the mantle.
What is differentiation in planetary geology quizlet?
What is differentiation in planetary geology? The process by which gravity separates materials according to density.
Which statement about IO is true?
Which statement about Io is true? It is the most volcanically active body in our solar system. Which of the following moons is considered likely to have a deep, subsurface ocean of liquid water? Which statement about planetary rings is not true?
What are 3 differences between continental crust and oceanic crust?
What are three differences between continental and oceanic crust? Continental crust is low in density whereas oceanic crust has a higher density. Continental crust is thicker, on the contrary, the oceanic crust is thinner. Continental crust floats on magma freely but oceanic crust floats on magma scarcely.
What are the differences between continental and oceanic plates?
Continental plates are much thicker that Oceanic plates. At the convergent boundaries the continental plates are pushed upward and gain thickness. The rocks and geological layers are much older on continental plates than in the oceanic plates. The Continental plates are much less dense than the Oceanic plates.
Why continental and oceanic crusts differ in their density?
Because continental crust is less dense than oceanic crust it floats higher on the mantle, just like a piece of Styrofoam floats higher on water than a piece of wood does. The mantle, oceanic crust and continental crust have different densities because they are made of different kinds of rock with different densities.
What drives the motion of the continental plates on Earth?
Earth’s tectonic plates are in constant motion. Their movement is driven by heat within the Earth. The deep Earth is very hot, while its surface is quite cool. This causes hot material within the Earth to rise, until it reaches the surface where it moves sideways, cools, then sinks.
What do we conclude if a planet has few impact craters of any size?
What do we conclude if a planet has few impact craters of any size? geological processes have erased craters. How many of the five terrestrial worlds are considered “geologically dead?”

In what ways is Earth different from the other terrestrial planets?
It differs from the other planets because it has liquid water on its surface, maintains life, and has active plate movement. It rotates on its axis every 24 hours (a day) and revolves around the Sun every 365 days (a year). The Earth has one moon.
Why do asteroids and comets differ in composition?
The main difference between asteroids and comets is their composition, as in, what they are made of. Asteroids are made up of metals and rocky material, while comets are made up of ice, dust and rocky material. Both asteroids and comets were formed early in the history of the solar system about 4.5 billion years ago.
Which of the following is a general difference between a planet and a star?
Planets are brighter than stars. Planets are larger than stars. Stars glow in infrared and visible light, while planets glow only in the infrared. Stars glow in infrared and visible light, while planets glow only in the infrared.
What is the main factor that makes Earth more geologically active than the other terrestrial planets?
Why is the Earth geologically active? Earth is Geologically active because it still has heat within the core. What is particularly unique about the Earth’s atmosphere? It protects the surface against solar radiation, makes our planet warm enough for liquid water to exist, and it is very thin.
What is differentiation and planetary geology?
Moon, Mercury, Mars, Venus, Earth. What is differentiation in planetary geology. the process by which gravity separates materials according to density. Under what circumstances can differentiation occur in a planet? the planet must have a molten interior.
What is differentiation in planetary geology group of answer choices?
In planetary science, planetary differentiation is the process of separating out different constituents of a planetary body as a consequence of their physical or chemical behavior, where the body develops into compositionally distinct layers; the denser materials of a planet sink to the center, while less dense …
When can differentiation occur in a planet?
When planets begin to melt, the materials in them begin to separate from one another. The heaviest materials, such as metallic iron, sink to form cores. Low-density magmas rise, forming crusts. This process is called differentiation.
Why is Io so geologically active?
With over 400 active volcanoes, Io is the most geologically active object in the Solar System. This extreme geologic activity is the result of tidal heating from friction generated within Io’s interior as it is pulled between Jupiter and the other Galilean moons—Europa, Ganymede and Callisto.
Why is Io yellow?
Composite image of Io and Jupiter (Jupiter image from the Cassini spacecraft, Io image from the new research). Sulfur dioxide plumes from Io’s volcanoes are seen in yellow.
Why is Jupiter’s moon Io not tidally locked?
Jupiter’s Moons
Jupiter is larger than all of its moons, so its gravitational pull is stronger than that of the moons. Since Jupiter is larger than its moons and has a stronger gravitational pull, this means the moons will be tidally locked to Jupiter, but Jupiter will not be tidally locked to the moons.

How continental and oceanic crust differ quizlet?
The oceanic crust is thinner and denser, and is similar in composition to basalt (Si, O, Ca, Mg, and Fe). The continental crust is thicker and less dense, and is similar to granite in composition (Si, O, Al, K, and Na). The mantle is made of magnesium, iron and silicon.
How do continental crust and oceanic crust differ quizlet?
Continental crust is thicker than oceanic crust; continental crust is less dense than oceanic crust; the oldest continental crust is older than the oldest oceanic crust; plus the continental crust is composed of a variety of rock types, whereas oceanic crust is composed of basalt and gabbro.
