divergent boundary
A divergent boundary occurs when two tectonic plates move away from each other. Along these boundaries, earthquakes are common and magma (molten rock) rises from the Earth’s mantle to the surface, solidifying to create new oceanic crust.
What is a complex plate boundary?
Continental convergent plate boundaries, where two continental slabs encounter each other, a more complex convergent plate boundary occurs. The interaction between these slabs causes intense deformation and mountain building, leading to the formation of a suture zone.
What would be found at a divergent boundary?
Effects that are found at a divergent boundary between oceanic plates include: a submarine mountain range such as the Mid-Atlantic Ridge; volcanic activity in the form of fissure eruptions; shallow earthquake activity; creation of new seafloor and a widening ocean basin.
What are the 3 boundaries of plate tectonics?
Tectonic Plates and Plate Boundaries
- There are three main types of plate boundaries:
- Convergent boundaries: where two plates are colliding.
- Divergent boundaries – where two plates are moving apart.
- Transform boundaries – where plates slide passed each other.
What are some examples of divergent boundaries?
Examples
- Mid-Atlantic Ridge.
- Red Sea Rift.
- Baikal Rift Zone.
- East African Rift.
- East Pacific Rise.
- Gakkel Ridge.
- Galapagos Rise.
- Explorer Ridge.
What landforms are created by Transform boundaries?
Linear valleys, small ponds, stream beds split in half, deep trenches, and scarps and ridges often mark the location of a transform boundary.
What happens when two plates meet at a convergent boundary?
Sometimes the molten rock rises to the surface, through the continent, forming a line of volcanoes. About 80% of earthquakes occur where plates are pushed together, called convergent boundaries. Another form of convergent boundary is a collision where two continental plates meet head-on.
Where do two tectonic plates grind against each other?
A transform boundary occurs where two tectonic plates _____. grind along each other convergent boundary area where tectonic plates meet and push against each other divergent boundary area where tectonic plates are moving away from each other transform boundary area where tectonic plates slide sideways past each other
What are the different types of plate boundaries?
There are three kinds of plate tectonic boundaries: divergent, convergent, and transform plate boundaries. This image shows the three main types of plate boundaries: divergent, convergent, and transform. Image courtesy of the U.S. Geological Survey. Download image (jpg, 76 KB).
What happens when two plates slide past each other?
Two plates sliding past each other forms a transform plate boundary. Natural or human-made structures that cross a transform boundary are offset—split into pieces and carried in opposite directions. Rocks that line the boundary are pulverized as the plates grind along, creating a linear fault valley or undersea canyon.
