There are three kinds of plate tectonic boundaries: divergent, convergent, and transform plate boundaries. This is a particularly interesting area to study because we can observe two types of plate boundaries (divergent and convergent) and their processes in very close proximity. A divergent boundary occurs when two tectonic plates move away from each other.here 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.

Why do tectonic plates move? If a plate with oceanic lithosphere meets another plate, the dense oceanic lithosphere dives beneath the other plate and sinks into the mantle: this process is called subduction. The sinking oceanic lithosphere drags the rest of the tectonic plate: this is the main cause of plate motion.

What is the shortest distance between stations on the london underground? The shortest distance between two stations is 250 metres (0.16 miles), between Leicester Square and Covent Garden on the Piccadilly line. Also if anyone wanted to know: The longest distance between two stations is 6.26 km (3.89 miles), between Chalfont & Latimer and Chesham on the Metropolitan line. Well I agree with you Kangkid.

- Rockhound. Plate tectonics cause earthquakes, and volcanoes. When the plates move they built up stress and when the faults release the fault cause and earth quake. There are different types of earthquakes that happen when plate collide. The main force that makes the earth move and tectonics plates form is the outer layer of the earth called lithosphere. They are what creates mountains to become higher a … nd the oceans to become wider because of the earth faults and folds. Sarahroxoutofhersox1.

What are tectonic plates and how do they move? The Earth's plates are riding on top of the currents caused by these processes. The main features of plate tectonics are: 1  The Earth's surface is covered by a series of crustal plates. 2  The plates are composed of crustal rock and solid upper mantle which is called the lithosphere.* 3  Plates are composed of continental and oceanic crust. The plates are composed of crustal rock and solid upper mantle which is called the lithosphere. * 2  Plates are composed of continental and oceanic crust. 3  The oceanic crusts are continually moving, spreading from the center, sinking at the edges, in a process of recycling.

astronomy ch 6-11 o Asthenosphere has convective motion. o This motion pushes lithosphere plates around. Plate tectonics is the movement of large portions of the crust. The movement is caused by magma squeezing out along the mid-oceanic ridges pushing the plates apart in a process called seafloor spreading.

What Are the Three Types of Plate Movement? The three types of plate movement are divergent, convergent and transform plate boundaries. Divergent occurs when two tectonic plates move away from the other. A convergent boundary is when two plates collide. A transform plate boundary occurs when two plates slide past each other.

Why do tectonic plates move? Tectonic plates move because they are floating on top of the liquid mantle. The mantle itself moves due to convection currents: hot rock rises, gives off some heat, then falls. This creates vast swirls of moving liquid rock under the crust of the earth, which jostles the plates of crust on top. Nobody really knows the details of the convection cells.

What are tectonic plates and how do they move? The movement of the plates is caused by the convection currents of heat from the Earth's interior. This heat, rising toward the surface through the mantle causes movement of plastic like rock in the asthenosphere, the layer of Earth directly below the lithosphere.he Earth's plates are riding on top of the currents caused by these processes. The main features of plate tectonics are: 1  The Earth's surface is covered by a series of crustal plates. 2  The plates are composed of crustal rock and solid upper mantle which is called the lithosphere.

When plates move 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. 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.

- Where the plates meet, their relative motion determines the type of boundary: convergent, divergent, or transform. Earthquakes, volcanic activity, mountain-building, and oceanic trench formation occur along these plate boundaries.The lateral relative movement of the plates typically ranges from zero to 100 mm annually. Convergent boundaries (Destructive) (or active margins) occur where two plates slide toward each other to form either a subduction zone (one plate moving underneath the other) or a continental collision.

Causes of Tectonic Plate Movement Thermal Convection. Scientists believe that one of the primary forces behind plate movement is thermal convection. Thermal convection is when heat from the core of the Earth is transferred to the surface of the Earth by the mantle. The mantle is the thick, mostly solid layer of the Earth between the crust and the core.

There are three kinds of plate tectonic boundaries: divergent, convergent, and transform plate boundaries. A divergent boundary occurs when two tectonic plates move away from each other. Along these boundaries, lava spews from long fissures and geysers spurt superheated water.Frequent earthquakes strike along the rift. Beneath the rift, magma—molten rock—rises from the mantle. divergent boundary occurs when two tectonic plates move away from each other. Along these boundaries, lava spews from long fissures and geysers spurt superheated water.

Plate Tectonics Plate Tectonics. Plate tectonics describes the motions of the 15 to 20 large rigid and brittle tectonic plates into which the Earth's outermost layer (called the lithosphere) is broken.his is a map of the main tectonic plates that comprise the Earth's surface: In the Pacific Northwest movement of three tectonic plates drive our earthquake hazard. The Pacific Plate is moving to the northwest at a speed of between 7 and 11 cetimeters (cm) or ~3-4 inches a year.

Plate Tectonics Notes 4. Another type of boundary neither creates nor consumes crust. This type of boundary is called a transformation boundary because two plates move against each other, building up tension, then release the tension is a sudden jerk of land called an earthquake. A. The boundary where two plates meet and trenches are formed. Oceanic and continental convergence. B. The plates move away from each other allowing magma to create new ocean crust. Divergent C. The plates move in opposite directions building up tension until they slip causing earthquakes. Transformation

Plate tectonics In the theory of plate tectonics, the earth's crust is broken into plates that move around relative to each other. As a result of this movement, three types of plate boundaries are formed: divergent, convergent, and transform boundaries.onvergent boundaries form strong earthquakes, as well as volcanic mountains or islands, when the sinking oceanic plate melts. The third type is transform boundaries, or a boundary where plates slide past each other, forming strong earthquakes.

- Plates move away from one another at divergent boundaries. This happens at mid-ocean ridges. Plates move towards one another at convergent boundaries; one plate is forced below another in a process called subduction. Earthquakes and composite volcanoes are common at this type of boundary.Plates move past on another at transform boundaries. The most famous example of this type of boundary is the San Andreas Fault in California.

Plate Tectonics There are three main driving forces for the movement of the Earth's tectonic plates. They are mantle convection, gravity, and the Earth's rotation. Mantle convection is the most widely studied method of tectonic plate movement and it is very similar to the theory developed by Holmes in 1929.

- What drives the process of plate tectonics. Tectonic plates are pieces of the Earth's crust and uppermost mantle, together referred to as the lithosphere. The plates are around 100 km thick and consist of two principal types of material: oceanic crust and continental crust. The composition of the two types of crust differs markedly, with basaltic rocks dominating oceanic crust, while continental crust consists principally of lower density granitic rocks.

Plate tectonics Where the plates meet, their relative motion determines the type of boundary: convergent, divergent, or transform. Earthquakes, volcanic activity, mountain-building, and oceanic trench formation occur along these plate boundaries.The lateral relative movement of the plates typically ranges from zero to 100 mm annually.late movement is thought to be driven by a combination of the motion of the seafloor away from the spreading ridge (due to variations in topography and density of the crust, which result in differences in gravitational forces) and drag, with downward suction, at the subduction zones.

How Crustal Plates Move: Plate Tectonics Plate tectonics is the unifying theory of geology. This theory explains how crustal plates move around the surface of the earth, and it allows geologists to find explanations for geologic events such as earthquakes and volcanoes, as well as the many other processes that form, transform, and destroy rocks.

Causes of Tectonic Plate Movement As this happens, the plates smash into each other, slide past each other or are pushed under another plate. This movement of the plate along with the upwelling of the mantle by the convection currents may also cause secondary actions that assist in plate movement.lab Pull. Another mechanism that forms as a result of plate movement is slab pull. As the plate is pushed along, it may run into another plate. Oceanic crust is easily forced under another plate and back into the mantle.
