Earthquakes, volcanic activity, mountain-building, and oceanic trench formation
occur along plate boundaries in zones that may be anything from a few kilometres to a few hundred kilometres wide.
What 2 geologic events are caused by the plate movement?
The theory of
plate tectonics
revolutionized the earth sciences by explaining how the
movement
of
geologic plates causes
mountain building, volcanoes, and earthquakes.
What geologic events occur at each plate boundary?
Movement in narrow zones along plate boundaries causes most
earthquakes
. Most seismic activity occurs at three types of plate boundaries—divergent, convergent, and transform. As the plates move past each other, they sometimes get caught and pressure builds up.
What are two geological processes that happen at convergent plate boundaries?
Tectonics. 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
.
What 2 geologic features are associated with plate boundaries?
Deep ocean trenches, volcanoes, island arcs, submarine mountain ranges, and fault lines
are examples of features that can form along plate tectonic boundaries. Volcanoes are one kind of feature that forms along convergent plate boundaries, where two tectonic plates collide and one moves beneath the other.
What are the boundary types?
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. … A divergent boundary occurs when two tectonic plates move away from each other.
What are the characteristics of transform plate boundaries?
Transform boundaries are
places where plates slide sideways past each other
. At transform boundaries lithosphere is neither created nor destroyed. Many transform boundaries are found on the sea floor, where they connect segments of diverging mid-ocean ridges. California’s San Andreas fault is a transform boundary.
What are the 3 causes of plate movement?
Mantle dynamics, gravity, and Earth’s rotation taken
altogether causes the plate movements. However, convectional currents are the general thought for the motion.
How does living near plate boundaries affect people’s lives?
Occasionally,
big eruptions or earthquakes kill large numbers of people
. … If we choose to live near convergent plate boundaries, we can build buildings that can resist earthquakes, and we can evacuate areas around volcanoes when they threaten to erupt.
What are the 4 plate boundaries?
There are four main types of plate boundary. These are
constructive, destructive, conservative and collision margins
.
In which two places do divergent boundaries occur?
Divergent boundaries are typified in the oceanic lithosphere by the rifts of the oceanic ridge system, including
the Mid-Atlantic Ridge and the East Pacific Rise
, and in the continental lithosphere by rift valleys such as the famous East African Great Rift Valley.
What landforms are created by divergent boundaries?
At DIVERGENT boundaries the plates move apart allowing molten magma to rise and form new crust in the form of ridges, valleys and volcanoes. Landforms created by divergent plates include
the Mid Atlantic Ridge and the Great African Rift Valley
.
What type of boundary is depicted in the image below?
What kind of boundary or zone is shown in the image below? Explanation: The plates are moving away from each other. This type of boundary is called
a divergent boundary
.
What are examples of convergent boundaries?
Examples. The
collision between the Eurasian Plate and the Indian Plate that is forming the Himalayas
. Subduction of the northern part of the Pacific Plate and the NW North American Plate that is forming the Aleutian Islands. Subduction of the Nazca Plate beneath the South American Plate to form the Andes.
Do convergent boundaries cause volcanoes?
Destructive, or convergent, plate boundaries are where the tectonic plates are moving towards each other. Volcanoes form here in two settings where either oceanic plate descends below another oceanic plate or an oceanic plate descends below a continental plate.
What are three types of convergent boundaries answers?
There are three types of convergent boundaries:
Oceanic-Continental Convergence
. Oceanic-Oceanic Convergence. Continental-Continental Convergence.
