SCIENCE WEEK 3 - LANDFORMS AND PROCESSES ALONG PLATE BOUNDARIES Flashcards
worldwide or local distribution of earthquakes in space, time, and magnitude; measure of frequency of earthquakes in a region
Seismicity
is associated with two of the plate boundary types
Volcanism
manifest themselves along volcanic rifts mostly in the ocean basins
Volcanism in Divergent Boundary
make individual volcanoes on the plate on the collission process
Volcanism in Convergent Boundary
4 Basic Landforms found along Plate Boundaries
Fold Mountains
Ocean Trenches
Volcanoes
Mid-ocean Ridges
are large mountain ranges where the layers of rock within them have been crumpled as they have been forced together; they are formed at destructive or collisional plate boundaries.
Fold Mountains
are deep water areas that run along a coastline which has a destructive plate margins; are created by subduction, and mark the point where the ocean crust is being pushed under the oceanic crust.
Ocean Trenches
they created more than 80 percent of our planet’s surface,
laying the foundation that has been allowed life to thrive
Volcanoes
volcanoes from here occur along oceanic-oceanic and oceanic-continental plates
Convergent Boundary
as the Earth’s crust is pulled apart to create a new pathway for rising hot magma to flow onto the surface
Divergent Boundary
form above a column of superheated magma called a mantle plume; is also known as intraplate volcanism
Hot Spot Volcanism
a continous range of underwater volcanoes that looks like a seams on a baseball that wraps around the globe.
