- Evolutionary biology. Convergent evolution is the independent evolution of similar features in species of different lineages. Convergent evolution creates analogous structures that have similar form or function but were not present in the last common ancestor of those groups. The cladistic term for the same phenomenon is homoplasy.

- Also, a synonym for; that is, an instance of a convergently evolved character, or a similar character in two species that was not present in their common ancestor. Examples include wings (convergent in birds, bats, and insects) and camera-type eyes (convergent in vertebrates and cephalopod mollusks).

- Summary of the study The goal of this convergent study was to use a larger sample of physics instructors from various higher education institutions to refine and expand an initial explanatory model of physics instructor’s conceptions about the problem-solving process in introductory calculus-based physics.

Convergent evolution In cultural evolution, convergent evolution is the development of similar cultural adaptations to similar environmental conditions by different peoples with different ancestral cultures. 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.

Convergent Boundary: Definition, Facts & Examples A convergent boundary (or destructive boundary) is where two plates are moving towards each other -- where they're colliding. The pressure and friction is great enough at these boundaries that the material in the Earth's mantle can melt, and both earthquakes and volcanoes happen nearby.xamples of Convergent Boundaries. The west coast of South America is a convergent boundary between the Nazca plate and the South American plate. The collision of this oceanic and continental plate was how the Andes mountains were formed.

- Divergent - when two plates pull away from each other. Convergent - Also known as subduction zones, where volcanoes and mountains are often found, crust is destroyed and recyc…led back into the Earth's interior as one plate goes under another. Oceanic-Continental - An oceanic plate will push against a continental plate and is subducted under it. 6 people found this useful.

Describe the three types of tectonic plate boundaries and motion that occurs at each type of boundaries? In plate tectonics, a convergent boundary, also known as a destructive plate boundary (because of subduction), is an actively deforming region where two (or more) tectonic plates or fragments of the lithosphere move toward one another and collide.escriptions [edit]. The nature of a convergent boundary depends on the type of plates that are colliding. Where a dense oceanic plate collides with a less-dense continental plate, the oceanic plate is typically thrust underneath because of the greater buoyancy of the continental lithosphere, forming a subduction zone.

- In plate tectonics, a convergent boundary, also known as a destructive plate boundary (because of subduction), is an actively deforming region where two (or more) tectonic plates or fragments of the lithosphere move toward one another and collide. subduction zone is formed at a convergent plate boundary when one or both of the tectonic plates is composed of oceanic crust. The denser plate, made of oceanic crust, is subducted underneath the less dense plate, which can be either continental or oceanic crust.

Jet Streams The two jet streams that directly affect our weather in the continental US are the polar jet and the subtropical jet. They are responsible for transporting the weather systems that affect us. The polar front is the boundary between the cold North Pole air and the warm equatorial air. The polar jet sits at roughly 60°N latitude because this is generally where the polar front sits. The subtropical jet is at roughly 30°N latitude.

Convergent Boundaries Convergent Boundaries. Convergent boundaries form when two crustal plates are colliding. The plates form a subduction zone with one plate descending beneath the other plate. One of the converging plates must be an oceanic plate to form a subduction zone. When two continental plates collide mountain ranges like the Himalayas form.

Convergent Evolution One way species change over time is called convergent evolution. Convergent evolution is when two species, that are not related via a recent common ancestor, become more similar. Most of the time, the reason behind convergent evolution occurring is the build up of adaptations over time to fill a certain niche. When the same or similar niches are available in different geographical locations, different species will most likely fill that niche.

Limit Comparison Test Limit comparison test is a test to decide whether the given series is divergent or convergent. Here, we consider two series and we will check how fast this series grow. We consider the limit here. If the limit is zero, then the term below grows faster than the other. So, the series below converges.

Eye convergence Convergence is the power of directing the visual axes of the two eyes to a point nearer than infinity, and is brought about by the action of the internal recti muscles. When the eyes are completely at rest, the optic axes are either parallel, or more usually slightly divergent.

Convergent Boundaries Convergent Boundaries. Converge is a large word that scientists use to describe two objects that come together. In the case of plate tectonics, the two objects coming together are large plate-like pieces of the Earth’s crust. As these two plates push against each other, one is ultimately forced down beneath the other.

Convergent boundary A convergent boundary is where two or more tectonic plates collide with each other causing massive earth movements. The Himalayas were formed by such a collision. Earthquakes and volcanoes are common near convergent boundaries. This is because of pressure, friction, and plate material melting in the mantle. Oceanic-continental

In plate tectonics, a convergent boundary, also known as a destructive plate boundary (because of subduction), is an actively deforming region where two (or more) tectonic plates or fragments of the lithosphere move toward one another and collide.n a subduction zone, the subducting plate, which is normally a plate with oceanic crust, moves beneath the other plate, which can be made of either oceanic or continental crust. During collisions between two continental plates, large mountain ranges, such as the Himalayas are formed. Oceanic-continental.

Earthquakes: tectonic plates 3. Convergent boundaries (also called transform faults) Convergent boundaries are the place where two tectonic plates converge (i.e. two plates move toward each other). These zones tend to be where compressional stresses are active and this results in thrust or reverse faults being common. Converging plate boundaries are of two types:

Answer help reset a c b lowest density highest Convergent boundaries occur where two plates collide into each other, and are associated with compressional stress. What type(s) of stress is associated with transform plate boundaries? Recall that strike­slip faults are what enable plates to slide past each other at transform boundaries. The three diagrams below show the three types of stresses: tension, compression, and shear.

What Is âConvergence and Divergenceâ? Convergence is the tendency of group members to become more alike over time. This is what’s known in business terms as “company’s culture.”. Divergence is the tendency of group members to become less like other group members over time. Convergence is useful if you consciously choose to spend time with people you’d like to become more like. At the same time, breaking away from groups that aren’t serving you is painful but necessary to grow.
