What kinds of magmas forms at divergent boundaries?
Usually a dense basaltic magma with low water content.
What kinds of volcanoes form on converging plate boundaries?
Composite cone volcanos are the most common.. Shielding and other types are results from a divergent boundary.
What type of volcanic rock is generally found at divergent plate boundaries?
If the divergent boundary is located between two ocean plates, the lava that erupts will likely be called mafic. This lava is relatively low in silica but high in magnesium and iron.
What type of boundary is along ocean ridges?
Constructive or divergent. The ridge formed is of basaltic rock type (though this is a generalisation), and is a source of volcanic activity. Iceland was formed as a result of the sea-floor spreading.
What are the 3 plate boundaries describe each?
a) Divergent Plate Boundaries: Divergent plate boundaries are locations where plates are moving away from one another. This occurs above rising convection currents. b) Convergent Plate Boundaries: Convergent plate boundaries are locations where lithospheric plates are moving towards one another. The plate collisions that occur in these areas can produce earthquakes, volcanic activity and crustal deformation. c) Transform Boundary: Transform Plate Boundaries are locations where two plates slide past one another. The fracture zone that forms a transform plate boundary is known as a transform fault. Most transform faults are found in the ocean basin and connect offsets in the mid-ocean ridges.

What kinds of magmas forms at divergent boundaries?
Usually a dense basaltic magma with low water content.
What happened at divergent boundaries?
divergent boundaries happen when 2 plates move apart or divide
Characterized by basaltic volcanism and seafloor spreading?
divergent
Which would you expect to cause the greatest amount of contact metamorphism an intrusion of basaltic magma or an intrusion of rhyolitic magma?
Basaltic magma

What is the midatlantic ridge?
The Mid-Atlanic Ridge is the divergent boundary that is responsible for seafloor spreading. Consisting mostly of divergent boundaries, with transform faults as well, this is the site where new oceanic crust is added, increasing the size of the ocean. This location is dotted with underwater volcanoes as igneous basaltic magma is added to fill in the gap left as the oceanic plates drift away.
Three types of plate boundaries?
Convergent (or destructive): Where two plates are moving toward each other. Collisions between oceanic plates results in subduction of the more dense plate. Collisions between an oceanic plate and a continental plate may result in the subduction of the oceanic plate because oceanic plates are more dense than continental plates. Collisions between two continental plates results in uplift and mountain formation where neither plate subducts.Divergent (or constructive): Where two plates are moving away from each other. Divergent plate boundaries are the site of new crust formation, particularly at the mid-ocean ridges, where spreading plates are infilled with basaltic magma from the asthenosphere.Transform (or conservative): Where two plates slide (actually 'grind') alongside each other and neither plate subducts. Earthquakes are common at transform faults due to the grinding and snapping movements of the plates as they move.
