Along What Type Of Tectonic Plate Boundary Would You Expect To Find The Youngest Crust? – Micro B Life
Convergent boundaries where two plates are moving toward each other are of three types depending on the type of crust present on either side of the boundary — oceanic or continental . The types are ocean-ocean ocean-continent and continent-continent.
New ocean crust is created at a divergent boundary. Movement of plates away from each other at divergent boundaries typically shows which of the following average velocities?
Also it showed that the youngest rock was found near the mid-ocean ridge while the oldest rock was furthest from the ridge just off the coast of the continents. In areas such as the Pacific Ocean basin any rocks older than 200 million years had since been consumed by the subduction zones (trenches).
Where are the youngest sediments found compared to the Mid-Atlantic Ridge? It is youngest at the opening of the ridge.
The YOUNGEST seafloor rocks are found CLOSE TO the mid-ocean ridge. The OLDEST seafloor rocks are found FAR AWAY FROM the mid-ocean ridge.
The ocean crust is everywhere younger than 200 million years (for example less than 5% of the age of the earth). The crust is youngest (still being created by volcanic eruptions) along the axis of the mid-ocean ridges and increases in age down the flanks of the mid-ocean ridges and out onto the deeper basin floors.
Why is oceanic crust so much younger than continental crust where do you find the youngest oceanic crust the oldest oceanic crust How old is it?
The oldest oceanic crust is about 260 million years old. This sounds old but is actually very young compared to the oldest continental rocks which are 4 billion years old. … It is due to the process of subduction oceanic crust tends to get colder and denser with age as it spreads off the mid-ocean ridges.
What is the youngest type of rock?
Because sedimentary rock forms in layers the oldest layer of undisturbed sedimentary rock will be on the bottom and the youngest on top.
Which lettered rock layer is the youngest?
Layer D is the youngest rock and layer A is the oldest.
Which of the following best explains why the oceanic crust is youngest at the oceanic ridges?
Explanation: Mid Ocean ridges are the source of new crustal material. It is thought that convection currents brings fresh magma to the surface at the divergent boundaries The youngest part of the world crust is found in oceanic crust next to the mid ocean ridges.
Where are the youngest rocks in the Earth’s crust found Brainly?
Answer: The youngest crust on Earth is most likely located at the mid-ocean ridge.
Where are the newest rocks on Earth found?
An astonishing new rock formation has been revealed in the Colorado Rockies and it exists in a deeply perplexing relationship with older rocks. Named the Tava sandstone this sedimentary rock forms intrusions within the ancient granites and gneisses that form the backbone of the Front Range.
Where are the youngest rocks in the Atlantic Ocean?
The rocks that make up the crust on the ocean’s floor are youngest near the Mid-Atlantic Ridge.

Where would you most likely find the oldest rocks on Earth?
Bedrock along the northeast coast of Hudson Bay Canada has the oldest rock on Earth. Canadian bedrock more than 4 billion years old may be the oldest known section of the Earth’s early crust.
Which of the following best describes where the youngest and oldest crustal rocks can be found on the earth?
Which of the following best describes where the youngest and oldest crustal rocks can be found on the Earth? The oldest crustal rocks are found at the North and South Pole and the youngest at the Equator.
Why are the oldest rocks found in the Marianas Trench?
Subduction zones occur where one part of the seabed—in this case the Pacific plate—dives beneath another the Philippine plate. … One reason the Mariana Trench is so deep he added is because the western Pacific is home to some of the oldest seafloor in the world—about 180 million years old.
What two major plates affect Mediterranean?
The tectonic framework of the eastern Mediterranean and Middle East region is dominated by the collision of the Arabian and African plates with Eurasia (e.g. McKenzie 1970 Jackson and McKenzie 1988).
Is Greece a convergent boundary?
Greece is at the intersection of several different tectonic regimes and is spanned by a zone of increased seismic hazard evidenced by the GEAR seismic hazard model. The earthquake is related to the convergent plate boundary that spans the southern boundary of Greece.
Where is the Mediterranean Sea?
Mediterranean Sea an intercontinental sea that stretches from the Atlantic Ocean on the west to Asia on the east and separates Europe from Africa. It has often been called the incubator of Western civilization.

Frequently Asked Questions About along what type of tectonic plate boundary would you expect to find the youngest crust?
If you have questions that need to be answered about the topic along what type of tectonic plate boundary would you expect to find the youngest crust?, then this section may help you solve it.
What kind of boundary would have the most recent crust?
To find the youngest rock, where would you look along a tectonic plate?
ocean ridges in the middle
What region of the North American plate is the youngest?
The youngest portion of the North American Plate is found along its boundary with the Eurasian plate, which is roughly halfway between the North American and European continents and is situated beneath the Atlantic Ocean.
Where in a divergent boundary can you find the oldest crust?
The oldest portions of the open ocean are 180 Ma on either side of the north Atlantic, and the oldest oceanic crust is around 280 Ma in the eastern Mediterranean.
Which boundary’s crust is the youngest?
All three rock types in the earth’s crust—igneous, sedimentary, and metamorphic—can also be recycled back to their original molten magma form, which occurs when oceanic crust is pushed back into the mantle at subduction zones. The youngest crust (shown in red) is located close to mid ocean ridges and spreading zones.
Which plate boundary results in fresh crust?
Divergent plate boundaries, which form submarine mountain ranges known as oceanic spreading ridges, are formed when two plates are moving apart from one another. Along these boundaries, magma rises from deep within the Earth and erupts to form new crust on the lithosphere.
Where can one find the youngest plates?
As the plates separate, magma rises from below the Earth’s surface to fill in the empty void, resulting in the youngest crust of the ocean floor being found close to the seafloor spreading centers or mid-ocean ridges.
Where on the seafloor does the oceanic crust appear to be the youngest?
The age, density, and thickness of oceanic crust increase with distance from the mid-ocean ridge, which is the actual site of seafloor spreading, and the youngest, thinnest crust on Earth is found close to its center.
Where is the Earth’s youngest crust to be found?
Answer and explanation: The mid-ocean ridges, which are divergent plate boundaries, where the tectonic plates are separating, are where the youngest rock in the Earth’s crust is found.
Which crust is the youngest and oldest?
In the Atlantic and Indian oceans, the oldest crust is found at the continental margin. The crust is youngest (still being created by volcanic eruptions) along the axis of the mid-ocean ridges and increases in age down the flanks of the mid-ocean ridges and out onto the deeper basin floors.
What kind of crust is the newest?
The term “crust” refers to the outermost layer of a planet that is made up of older, thicker continental crust and younger, denser oceanic crust. Plate tectonics helps to explain the dynamic geology of the Earth’s crust.
Where is the most likely location for the youngest crust of the earth?
Explanation: The earth’s crust is the planet’s outermost layer, and it is generally divided into older, thicker continental crust and younger, denser oceanic crust. The youngest crust of the earth can be found close to the seafloor spread in the centers or mid-ocean ridges.
