Which is the best example of a convergent plate boundary? Answer: The Washington-Oregon coastline of the United States is an example of this type of convergent plate boundary. Here the Juan de Fuca oceanic plate is subducting beneath the westward-moving North American continental plate. The Cascade Mountain Range is a line of volcanoes above the melting oceanic plate.
What are examples of convergent?
Convergent evolution is when different organisms independently evolve similar traits. For example, sharks and dolphins look relatively similar despite being entirely unrelated.
What are the similarities between convergent divergent and transform boundaries?
The similarities are that a boundary of any kind marks the line between two tectonic plates. Similarities between divergent and convergent boundaries include magma or lava flows, formation of new topographic features and re-shaping of landmasses.
How do convergent boundaries affect humans?
If we choose to live near convergent plate boundaries, we can build buildings that can resist earthquakes, and we can evacuate areas around volcanoes when they threaten to erupt. Yes, convergent boundaries are dangerous places to live, but with preparation and watchfulness, the danger can be lessened somewhat.
Do convergent boundaries cause volcanoes?
Volcanoes are most common in these geologically active boundaries. The two types of plate boundaries that are most likely to produce volcanic activity are divergent plate boundaries and convergent plate boundaries. At a divergent boundary, tectonic plates move apart from one another.
What are 2 examples of convergent evolution?
An example of convergent evolution is the similar nature of the flight/wings of insects, birds, pterosaurs, and bats. All four serve the same function and are similar in structure, but each evolved independently.
What are examples of coevolution?
Coevolution occurs when species evolve together. Coevolution often happens in species that have symbiotic relationships. Examples include flowering plants and their pollinators.
Is convergent evolution rare?
When multiple taxa independently evolved the same trait to cope with the same, or similar, environmental pressures, the trait is likely adaptive in that environment. … As each paper in this issue shows, convergent evolution at the phenotypic level is rather common.
What do convergent boundaries cause?
When two plates come together, it is known as a convergent boundary. The impact of the colliding plates can cause the edges of one or both plates to buckle up into a mountain ranges or one of the plates may bend down into a deep seafloor trench.
What is an important difference between transform plate boundaries and convergent and divergent plate boundaries?
Divergent boundaries — where new crust is generated as the plates pull away from each other. Convergent boundaries — where crust is destroyed as one plate dives under another. Transform boundaries — where crust is neither produced nor destroyed as the plates slide horizontally past each other.
Is it safe to live near divergent boundaries?
Most of the hazards that characterize a divergent plate boundaries lie under the ocean but on land the hazards are faults, volcanoes , and the most obvious one; earthquakes. The history of any one part of the Earth, like the life of a soldier, consists of long periods of boredom and short periods of terror.
How are convergent boundaries formed?
If two tectonic plates collide, they form a convergent plate boundary. Usually, one of the converging plates will move beneath the other, a process known as subduction. … The new magma (molten rock) rises and may erupt violently to form volcanoes, often building arcs of islands along the convergent boundary.
What are the dangers of living near a plate boundary?
Some of the most destructive natural hazards that occur on Earth—earthquakes, tsunamis and volcanic eruptions—are associated with tectonic plate boundaries.
Do convergent boundaries cause tsunamis?
Most large tsunamis occur at convergent plate boundaries where two tectonic plates are crashing into each other. As the two plates collide one plate is forced down underneath the other. … When these megathrust earthquakes occur under water large amount of water is displaced and a tsunami wave occurs.
Why do convergent boundaries cause volcanoes?
If two tectonic plates collide, they form a convergent plate boundary. Usually, one of the converging plates will move beneath the other, a process known as subduction. … The new magma (molten rock) rises and may erupt violently to form volcanoes, often building arcs of islands along the convergent boundary.
How does convergent evolution occur?
Convergent evolution occurs when species occupy similar ecological niches and adapt in similar ways in response to similar selective pressures. Traits that arise through convergent evolution are referred to as ‘analogous structures’. They are contrasted with ‘homologous structures’, which have a common origin.
Are Darwin’s finches an example of convergent evolution?
Darwin’s Finches are an example of. A. Convergent evolution. … All species of Darwin’s finches were closely associated with each other, having derived recently (in geological terms) from a common ancestor.
What is difference between convergent and divergent evolution?
Convergent Evolution vs.
Whereas convergent evolution involves unrelated species that develop similar characteristics over time, divergent evolution involves species with a common ancestor that change to become increasingly different over time.
What are the two types of coevolution?
Two Types of Coevolution
- Predation is when one organism kills and eats another organism. The prey is the species that gets eaten by the predator, which is of course the species that eats the prey.
- Parasitism is when one organism benefits by damaging, but not killing, another organism.
What is coevolution in simple terms?
Coevolution, the process of reciprocal evolutionary change that occurs between pairs of species or among groups of species as they interact with one another. The activity of each species that participates in the interaction applies selection pressure on the others.
What are the 5 types of coevolution?
A few different categories of coevolution are often discussed by scientists in ecology and evolutionary biology: pairwise coevolution, diffuse coevolution, and gene-for-gene coevolution. Pairwise coevolution (or ‘specific’ coevolution) describes tight coevolutionary relationships between two species.
When would convergent evolution occur?
Convergent evolution occurs when species occupy similar ecological niches and adapt in similar ways in response to similar selective pressures. Traits that arise through convergent evolution are referred to as ‘analogous structures’.
Is convergent evolution common?
Convergent evolution occurs in all biological kingdoms, and it is particularly noticeable in plant species and animal species. The only requirement is that two species, lacking a common ancestor, undergo independent evolution that results in similar body forms or similar useful traits.
What are the 3 types of convergent boundaries and what do they cause?
Three types of convergent boundaries are recognized: continent‐continent, ocean‐continent, and ocean‐ocean.
- Continent‐continent convergence results when two continents collide. …
- Ocean‐continent convergence occurs when oceanic crust is subducted under continental crust.
Why does magma form at a convergent boundary?
At convergent boundaries magma is formed where water from a subducting plate acts as a flux to lower the melting temperature of the adjacent mantle rock. … The higher viscosity prevents gases from escaping from the magma, and so felsic magmas are more pressurized and more likely to erupt explosively.
What are the 4 types of tectonic plate movement?
What are the major plate tectonic boundaries?
- Divergent: extensional; the plates move apart. Spreading ridges, basin-range.
- Convergent: compressional; plates move toward each other. Includes: Subduction zones and mountain building.
- Transform: shearing; plates slide past each other. Strike-slip motion.
