What is the difference between divergent plate boundaries and convergent plate boundaries?
Okay this is going to be long :X IN GENERAL... Divergent Plate Movement (plates move away from each other)- Continental and continental, oceanic and oceanic -Constructive Plate Boundary Convergent Plate Movement (plates move towards each other)- Continental and Oceanic, Oceanic and Oceanic, Continental and Continental -Destructive Plate Boundary Transform Plate Movement (plates sliding past each other)- Continental and Continental -Conservative Plate Boundary DIVERGENT PLATE MOVEMENT When plates move apart, magma wells up from Earth's mantle to form a new ocean floor with mid-oceanic ridges. It is a constructive plate boundary because new land crust is being created. O & O (Oceanic and Oceanic) Oceanic Ridges and Submarine volcanoes are formed. Shallow earthquakes may occur and there may be volcanic activity. Magma from the deeper mantle wells up into the gap formed when two oceanic plates move away from each other, and some of it melts and is erupted on the surface as lava, while others are injected near the surface to crystallize as other igneous rocks. The seafloor may also spread, and magma rises to the floor and solidify, forming new crust. Therefore it is a constructive plate boundary as new crust is formed and added to the ocean floor. An example of the resulting landforms would be the Mid-Atlantic Ridge. C & C (Continental and Continental) When two continental plates move away from each other, a sea is formed. E.g. Red Sea. CONVERGENT PLATE MOVEMENT When plates move towards each other, they may collide. When 2 oceanic plates collide, plate edges are bent into a deep trench called the subduction zone. It is a destructive plate boundary because the subducted plate is destroyed in the process. O & O Subduction takes place, and the over-riding plate (the plate above) folds and form islands, whilst the heavier plate sinks into the mantle of the Earth and is melted away by the magma. The magma rises and forms volcanoes. E.g. Japan. C & O When an oceanic plate collide with a continental plate, the oceanic plate sinks as it has a larger density. Lithosphere materials from the oceanic crust are subducted in the trench whilst the continental border is fractured, folded and uplifted. Magma rises and a mountain accompanied by volcanic activity are formed. E.g. Andes Mountains. C & C When two continental plates collide, neither sinks because they have similar densities. The continental lithosphere buckles and is uplifted instead, forming fold mountains. Little volcanic activity occur as rocks from the lithosphere do not sink deep into the asthenosphere (upper mantle zone) Earthquakes, faulting and folding however, are common. E.g. Himalayas. TRANSFORM PLATE MOVEMENT Occurs when two plates slip past each other. Tear faults form, accompanied by earthquakes due to great amount of stress built up in these areas, but there is little volcanic activity and little crustal material is destroyed.
What are the major types of tectonic plate boundaries?
The major types of plate tectonic boundaries are:Divergent Plate Boundary: The area where two plates are moving in relatively opposite directions and new crustal material is being created. Examples would be the mid-ocean ridges, and the East African Rift.Convergent Plate Boundary: The area where two tectonic plates are moving toward each other and one of two things happens; either the more dense plate subducts under the lighter plate and heads toward the mantle, or, if the plates are of similar density, they cause uplift and mountain forming events. Examples would be the oceanic to continental crustal collision creating the Andes Mountains, and the continental to continental crustal collision creating the Himalayan Mountains.Transform Plate Boundary: The area where two plates are grinding past each other, snapping into place from elastic rebound as they go, causing numerous earthquakes. The San Andreas Fault is an example of a transform plate boundary between the North American and Pacific plates.Convergent (plates are crashing together), divergent (plates are spreading apart), and transverse (plates are grinding past each other.) There are key structures that you get at each: Convergent boundaries can produce subduction or uplift, resulting in mountains and volcanoes. Divergent boundaries form mid-oceanic ridges and rift valleys. Transverse boundaries create faults, and are prone to earthquakes.They are all boundaries between or fractures within the Tectonic Plates forming the Earth's crust.A convergent boundary is that between two approaching plates; usually an ocean-floor plate being subducted beneath the continental plate as the ocean closes. This is happening now to the Pacific Ocean.A divergent boundary is the opposite: the fracture of plate into two parts moving away from each other. The break is closed by upwelling magma. E.g. The Mid-Atlantic Ridge - the Atlantic is presently widening away from this subsea mountain-range at a mean rate of about 25mm/yr.Transform boundaries, or Transform Faults, are shear fractures across the plate at roughly right-angles to the spreading-ridge from which the emanate. They represent the effect of unequal spreading forces. If you look at a relief map of the Atlantic Ocean bed you will see many transform faults to E and W of the Mid-Atlantic Ridge
Are European goldfinch and pine finch convergent or divergent?
Im pretty sure they are divergent because they are both from the same bird family and follow common traits such as beak shape, colour but their body shape has been adapted to fit in both environments.
In what ways was the flowing lava model similar to the actual flow of lava on Earth?
The flowing lava model was similar to the actual flow of lava on Earth in terms of its movement and behavior, as it demonstrated how lava flows and spreads out in a similar manner to real volcanic eruptions.
Why fossils support the theory of continental movement?
Fossils found on different continents with similar characteristics suggest that these landmasses were once connected millions of years ago. As continents drift apart, similar fossils can only be explained by the movement of landmasses over time, supporting the theory of continental drift. This provides evidence that different continents were once part of a single supercontinent, such as Pangaea.
How are the movement at divergent boundaries and at transform boundaries similar?
They are not similar, divergent boundaries are where the move apart. transform boundaries are where the two plates rub together and move in opposite directions with great force.

How are the movement of plates at divergent boundaries and transform boundaries similar?
Both divergent and transform boundaries involve the movement of tectonic plates. At divergent boundaries, plates move away from each other, leading to the formation of new crust. At transform boundaries, plates slide past each other horizontally, causing earthquakes along the boundary. Both types of boundaries are associated with plate movement and the interaction between tectonic plates.
How are the movement of plates at divergent boundaries and at the transform boundaries similar?
The difference between transform and divergent boundaries is that transform boundaries occur when tectonic plates slide past each other, whereas at divergent boundaries they move away from each other. However in both cases the plates move horizontally (unlike at convergent boundaries where one plate may be pushed underneath another).
How is divergent convergent and transform plate boundaries similar?
Divergent, convergent, and transform plate boundaries are all types of interactions between tectonic plates. They all involve movement of the Earth's lithosphere and are associated with various geologic features such as earthquakes and volcanic activity. These boundaries play a crucial role in shaping the Earth's surface and influencing geological processes.
How is lava at divergent boundaries similar to lava at hot spot?
Yes.
How are the movement of plates at the divergent boundaries and at sliding boundaries similar?
There are three kinds of plate boundaries:spreading boundaries, colliding boundaries, and sliding boundaries. The platea move at amazing show rates, from about 1 to 24 centimeters per year. Thet have been moving for tens of millions of years.
How is similar divergent plate boundary and transform plate boundary?
They are similar because they both form volcanoes and earthquakes.

Occurs when species that were similar become increasingly distinct?
Divergent evolution:)
