A theory stating that the earth's surface (lithosphere) is broken into large slabs of rock (plates) that are continually moving and interacting with each other. Mid-Ocean Ridges are mountains that form on the ocean floor and with a total length over forty thousand miles. The third type is transform boundaries, or boundaries where plates slide past each other, forming strong earthquakes. Geological features of Convergent Plate Boundaries. In basic terms, the earth's crust (lithosphere) is broken up into tectonic plates which float on a liquid mantle beneath and move due to convection currents producing features such as volcanoes, earthquakes, rift valleys and ocean trenches at plate boundaries. A San Andreas fault С. Мt. 1. This PowerPoint is a lesson, especially for grade 10 students and teachers. Earthquakes are a common feature associated with divergent plate boundaries and can occur by several processes including: magma making its way through the brittle lithosphere, movement along transform featurex, divergence or normal faulting as the plates spread apart and cooling, and contraction of the lithosphere as it moves away from the ridge. These boundaries can be found on continental or oceanic lithospher e. Tensional stress operates between the tectonic plates at a divergent boundary, which causes the lithosphere at these locations to stretch and pull apart. Plate Tectonics - Learning Outcomes; 2. Himalayas D. Rift Valley 14. Some divergent boundaries are on the ocean floor where the lithosphere is thin; others are on land.

Elizabeth Johnson. Most seismic activity occurs at three types of plate boundaries—divergent, convergent, and transform. 21.12). Oceanic crust divergent plate boundary features: new oceanic crust. The Earth's crust is pulled apart to create a new pathway for rising hot magma to flow on to the surface. Now come to the main point: Geological Features When two oceanic plate diverge then new sea floor is created by a process called sea floor spreading and features like Mid oceanic ridges, volcanoes & Young lava flows forms. Divergent Boundary. Khan Academy is a 501(c)(3) nonprofit organization. Compare rift valley from mid-ocean ridge. Chapter 10 Plate Tectonics. In the western part of the continent, divergent plate boundary forces are beginning to rip the continent apart, forming the Basin and Range Province and its adjacent eastern arm, known as the Rio Grande Rift. The vast majority of divergent boundaries are found in the ocean, where they were not mapped or understood until the mid-to-late 20th century. Plate tectonics begin at mid-oceanic ridges where plates are moving apart.Because plates pull apart from each other at divergent plates, lava spews out to create the youngest geological rocks on Earth.. Another example of a divergent plate is at the African major plate where it's in the process of rifting apart into two . East Pacific Rise, Mid-Adlantic Ridge. Created by Sal Khan.Watch the next lesson: https://www.khanacademy.org/science/cosmolog. The East African Rift is an example of a single tectonic plate being ripped in two. At divergent boundaries, sometimes called constructive boundaries, lithospheric plates move away from each other. Deep ocean trenches, volcanoes, island arcs, submarine mountain ranges, and fault lines are examples of features that can form along plate tectonic boundaries. Plate Boundaries 1. And in particular, I want to focus on the features we see at divergent plate boundaries, where the plates are moving away from each other, or where new . In plate tectonics, a divergent boundary or divergent plate boundary (also known as a constructive boundary or an extensional boundary) is a linear feature that exists between two tectonic plates that are moving away from each other. 14 What features would you expect to find at an ocean ocean divergent plate boundary? 32 Geologic Structures and Plate Tectonics .

Facts about the Divergent Plate Boundary. Because the new crust formed at the plate boundary is warmer than the surrounding crust, it has a lower density so it sits higher on the , creating the mountain chain. Divergent boundaries within continents initially produce rifts, which eventually become rift . 2. The processes and landforms associated with movements within the lithosphere and asthenosphere. This process results in the formation of a trench. widened ocean basins. Difference between Crust and Lithosphere; 3. The majority of divergent plate boundaries are underwater, forming submarine mountain ranges known as . As these plates slowly move about, they interact with each other, forming boundary zones. This pushing creates frequent and severe earthquakes, like the famous San Francisco earthquake. Plate tectonics: Geological features of divergent plate boundaries. Most divergent plate boundaries are underwater and form submarine mountain ranges called oceanic spreading ridges. 6 Which plate boundary is formed between the Philippine plate and the Eurasian Plate?

This underwater mountain range is constantly growing as new crust is formed. Structure of the Earth; 4. Divergent boundaries occur along spreading centers where plates are moving apart and new crust is created by magma pushing up from the mantle. This lateral flow causes the plate material above to be dragged along in the . 10 What is an oceanic oceanic convergent boundary? Trenches are geological features formed by convergent boundaries. Adapted from Physical Geology, First University of Saskatchewan Edition (Karla Panchuk) and Physical Geology (Steven Earle) Figure 4.1: Iceland is known for its volcanoes, which are present because Iceland is located on the Mid-Atlantic Ridge, where the Atlantic Ocean is spreading apart and new crust is forming. A divergent plate boundary occurs when two plates move away from each other. Divergent plate boundaries are where two plates are moving apart from one another (Ritter, 2012). The topographic features that develop at this boundary are due to extension of the plate boundaries which causes rifting in continental and oceanic crusts (Strahler, 2011, 419). When two tectonic plates converge, the heavier plate is forced downward, creating a subduction zone. convergent boundary is formed where two tectonic plates collide with each other. transform fault earthquakes Divergent boundaries shield volcanos and rift valleys. Divergent boundaries occur along spreading centers where plates are moving apart and new crust is created by magma pushing up from the mantle. Divergent boundaries exist where tectonic plates move apart from each other. Check out a sample Q&A here.

Divergent plate boundaries are where two plates are moving apart from one another (Ritter, 2012). 2) Differentiate between divergence in a continental plate and divergence in an oceanic plate. 2. What do divergent boundaries form? Picture two giant conveyor belts, facing each other but slowly moving in opposite directions as they transport newly formed oceanic crust away from the ridge crest. Réponse publiée par: nila93 Subduction is a geological process that takes place at convergent boundaries of tectonic plates where one plate moves under another and is forced to sink due to high gravitational potential energy into the mantle. Basalt is both fluid and dry (low volatile content) Therefore, non-explosive. Divergent boundaries. Convergent boundaries form strong earthquakes, as well as volcanic mountains or islands, when the sinking oceanic plate melts. •The word, tectonic, refers to the deformation of At a convergent plate boundary, one plate dives ("subducts") beneath the other, resulting in a variety of earthquakes and a line of volcanoes on the overriding plate; Transform plate boundaries are where plates slide laterally past one another, producing shallow earthquakes but little or no volcanic activity. underwater volcanoes. The rising current pushes up on the bottom of the lithosphere, lifting it and flowing laterally beneath it. When plates collide with each other = Convergent boundary 2. What are the Geological features of divergent? As the plates move past each other, they sometimes get caught and pressure builds up. Volcanoes are one kind of feature that forms along convergent plate boundaries, where two tectonic plates collide and one moves beneath the other. . Unlike convergent boundaries, divergence occurs between only oceanic or only continental plates, not one of each. Deep ocean trenches, volcanoes, island arcs, submarine mountain ranges, and fault lines are examples of features that can form along plate tectonic boundaries. Divergent plate boundaries form other unique geological, chemical and biological features described in more detail, below. Watch this video to learn about plate tectonic stresses and types . 3. After carefully reading this chapter, completing the exercises within it, and answering the questions at the end, you should be able to: Discuss some of the early evidence for continental drift and Alfred Wegener's role in promoting this theory. The Nazca Plate contains several very noticeable hotspots that have helped create numerous interesting geologic features. When the plates finally give and slip due to the increased pressure, energy is released as seismic waves, causing the ground to shake. 19 What are the types . deep-sea vents.
