When two plates are moving away from each other, we call this a
divergent plate boundary
. Along these boundaries, magma rises from deep within the Earth and erupts to form new crust on the lithosphere. Most divergent plate boundaries are underwater and form submarine mountain ranges called oceanic spreading ridges.
What geologic features are formed when two plates slide past each other?
When oceanic or continental plates slide past each other in opposite directions, or move in the same direction but at different speeds,
a transform fault boundary
is formed. No new crust is created or subducted, and no volcanoes form, but earthquakes occur along the fault.
What geologic features are formed through each type of plate boundaries?
As these plates slowly move about, they interact with each other, forming boundary zones. Each of these different types of plate boundaries produces unique geographical features on the surface, including
fault lines, trenches, volcanoes, mountains, ridges and rift valleys
.
What features form when two plates diverge?
When two oceanic plates diverge,
underwater ridges and mountain ranges form
, such as the mid-Atlantic Ridge. … Eventually these mountain ranges can rise above the water to form islands. When two continental plates diverge, great rift valleys can form.
What geologic feature is are formed?
Geologic features created by the influence of tectonic forces include folds, which are bent or tilted layers in sedimentary rocks and faults that offset rock layers and fractures in rocks as well as mountains. Plate tectonics creates
mid-ocean ridges
and deep ocean trenches at subduction zones.
What geological features are created at convergent divergent and transform plate boundaries?
Convergent boundaries form
strong earthquakes
, as well as volcanic mountains or islands, when the sinking oceanic plate melts. The third type is transform boundaries, or boundaries where plates slide past each other, forming strong earthquakes.
What happens when two plates move away from each other?
A divergent boundary
occurs when two tectonic plates move away from each other. … Magma rises into and through the other plate, solidifying into granite, the rock that makes up the continents. Thus, at convergent boundaries, continental crust is created and oceanic crust is destroyed.
What happens when two plates move toward each other?
When two plate move towards each other they
converge or come together
. The collision between two plates that are moving towards each other is called a convergent boundary. … The collision results in large damaging earthquakes. When two continental plates converge the result is the formation of large folded mountains.
What geologic feature will be formed if the continents riding on top of two convergent collide?
When two plates carrying continents collide, the continental crust buckles and rocks pile up, creating
towering mountain ranges
. The Himalayas were born when the Indian subcontinent smashed into Asia 45 million years ago.
What geologic events take place with the convergence of two oceanic plates?
An oceanic-to-oceanic plate boundary
occurs when two oceanic plates converge, causing the older, denser plate will subduct into the mantle. An ocean trench marks the location where the plate is pushed down into the mantle. The line of volcanoes that grows on the upper oceanic plate is an island arc.
What geological features occur in 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.
Which geologic features are associated with divergent boundaries?
Divergent Plate boundaries are associated with
Very long underwater mountain ranges known as ridges
. Between the Ridges is a Rift Valley. This is where Sea Floor Spreading occurs. There are underwater hydrothermal vents and paleomagetic banding.
What are two geological features?
There are
peaks, valleys, jagged edges, rolling hills, and everything in between
. In general, we call these geological features, but this term is very broad and refers to any of the physical features on Earth’s surface. You might also hear them referred to as landscapes, topography, and landforms.
What happens when two oceanic plates collide?
When two oceanic plates collide
one oceanic plate is eventually subducted under the other
. Where one plate slides under the other is referred to as the ‘subduction zone’. As the subducting plate descends into the mantle where it is being gradually heated a benioff zone is formed.
What is formed after the plates has moved?
When the plates move they collide or spread apart allowing the very hot molten material called
lava
to escape from the mantle. When collisions occur they produce mountains, deep underwater valleys called trenches, and volcanoes. … The Earth is producing “new” crust where two plates are diverging or spreading apart.
What geologic forces drive tectonic movements?
Heat and gravity are fundamental to the process
The energy source for plate tectonics is Earth’s internal heat while the forces moving the plates are the
“ridge push” and “slab pull” gravity forces
.
