Which one of these results is possible when two oceanic plates collide?
ESci Unit3 Flashcards, Matching and Concentration, Word Search
|This results when divergence occurs between two oceanic plates.||*seafloor spreading|
|This kind of plate boundary occurs where two plates grind laterally past each other parallel to the boundary without destroying or producing lithosphere.||transform fault|
What type of boundary occurs where to plates move together causing one play to descend into the mantle beneath the other plate?
Subduction takes place in convergent borders, where the denser oceanic plate falls into the mantle below the plate. Convergent boundaries can also produce curved and linear mountain belts. Transform boundaries are more likely to have low earthquakes than volcanoes.
Which list places the locations in correct sequence with initial seafloor spreading first followed by more advanced stages in the process?
Answer Expert Verified. The correct sequence for the initial seafloor, followed by the advanced stages of the seafloor spreading process, is (1) formation of African red sea (2) Red Sea (3) Atlantic ocean.
What is the difference between rifting and seafloor spreading?
Continental Drift is very similar to seafloor spreading. Continental drift refers to the gradual movement over time of continental plates across the Earth’s surface. Seafloor spreading refers to the formation of new areas in the oceanic crust as a result of the upwelling magma, which is caused by the oceanic aparts pulling apart.
How do you know seafloor spreading?
Seafloor spreading takes place at the boundaries of divergent plates. The crust becomes more plastic as the tectonic plates move away from one another. The less dense material rises and forms mountains or higher areas of the seafloor.
How do scientists make detailed maps of the seafloor?
Echo sounding remains the most important method used by scientists to map the seafloor. The technique, first used by German scientists in the early 20th century, uses sound waves bounced off the ocean bottom. Transducers are components that transmit and receive sound waves from ships.
Which is the largest zone in the ocean?
The next deepest zone, or the lower open ocean, is called the bathypelagic. This zone starts at the bottom of the mesopelagic and stretches down to 4000 m (13,000 feet). The bathypelagic is much larger than the mesopelagic and 15 times the size of the epipelagic. It is the largest ecosystem in earth.
What are scientists doing to find out more about deep sea creatures?
A new paper in PLOS One last week describes how scientists can track deep-sea creatures using DNA found in seawater. Each organism has its own unique genome. Many animals lose bits of DNA when they shed skin cells, poop, or other bodily fluids.
Do Satellites use sonar?
Satelites measure the depth in a completely different way. Satellites measure depth using the ocean surface. These data can also be used, just like sonar, to create detailed ocean floor maps. A submersible, a small craft that can be used to deep-sea research, is called.
How deep in the ocean can satellites see?
Among the new features they’re now able to detect, Sandwell says, are thousands of previously unknown seamounts between 1000 and 2000 meters tall dotting the ocean floor.
How accurate are satellites?
Satellites transmit location information to your device via radio waves. It’s accurate for 7.8 meters, 95% of the time.
Why does the ocean look bumpy on Google Maps?
Unusual grid patterns on maps of the oceanfloor are created by ships using higher-resolution sonar readings – to create better maps! These lines show the paths that ships used to map smaller sections of the ocean floor using sonar.
How far can satellites see?
Although many details remain classified about this class, it is known there are many of them overhead at any one time. Their imaging resolution is 5-6 inches. This means that they can see objects 5 inches and larger from the ground.
