What are collisions? Explain the possible types of collisions. [2]
What are collisions? Explain the possible types of collisions.. A collision happens when two bodies come in direct contact with each other
The energy and momentum of bodies interacting undergo a change as a result of the collision. Moreover, the collision may occur through actual physical contact of the bodies involved
There may not be any actual physical contact between the two bodies involved in the collision. For instance, the bombardment of alpha particles on the atomic nucleus.

Plate Boundaries: Divergent, Convergent, and Transform [4]
Plate Boundaries: Divergent, Convergent, and Transform. Movement in narrow zones along plate boundaries causes most earthquakes
As the plates move past each other, they sometimes get caught and pressure builds up. When the plates finally give and slip due to the increased pressure, energy is released as seismic waves, causing the ground to shake
The movements of the plates help shape the geological features of our planet. Divergent (Spreading):This is where two plates move away from each other
3.8 Conservative plate boundaries and transform faults [5]
3.8 Conservative plate boundaries and transform faults. Conservative plate boundaries and transform faults occur when plates slide past each other in opposite directions, but without creating or destroying lithosphere
those that link two segments of a constructive boundary. those that link a destructive boundary with a constructive boundary.
Accordingly, this type of ocean transform fault forms an integral part of constructive plate boundaries, and their position is made obvious by the jagged shape of parts of the ocean-ridge system that are split into several segments by series of so-called fracture zones. Examples can be easily seen on the Cocos-Nazca Ridge (also known as the Galapagos Spreading Centre), and the Pacific Ocean spreading ridge (i.e
Transform fault [6]
A transform boundary occurs when two tectonic plates move past one another. Shear stress operates at transform boundaries, which involves sliding motion
They accommodate the lateral offset between segments of divergent boundaries, forming a zigzag pattern. This is a result of oblique seafloor spreading where the direction of motion is not perpendicular to the trend of the overall divergent boundary
Transform boundaries are also known as conservative plate boundaries because they involve no addition or loss of lithosphere at the Earth’s surface.[1]. Geophysicist and geologist John Tuzo Wilson recognized that the offsets of oceanic ridges by faults do not follow the classical pattern of an offset fence or geological marker in Reid’s rebound theory of faulting,[2] from which the sense of slip is derived
Transform fault | Plate Tectonics, Earthquakes & Volcanoes [7]
Our editors will review what you’ve submitted and determine whether to revise the article.. transform fault, in geology and oceanography, a type of fault in which two tectonic plates slide past one another
The spatial orientation of transform faults is typically parallel to plate motions; however, this is not always the case. Transform faults are the only segments of fracture zones that are seismically active.
Morgan proposed that opposing plates along an oceanic ridge crest offset by fracture zones are divided by the spreading centres and transform faults. The inactive portions of the fracture zone on the ridge flanks are scars on the ocean floor created in the transform faults
Continental Movement by Plate Tectonics [8]

The earth’s crust is broken into separate pieces called tectonic plates (Fig. Recall that the crust is the solid, rocky, outer shell of the planet
What causes earthquakes? [9]
Earthquakes are the result of sudden movement along faults within the Earth. The movement releases stored-up ‘elastic strain’ energy in the form of seismic waves, which propagate through the Earth and cause the ground surface to shake
Seismic waves from large earthquakes pass throughout the Earth. These waves contain vital information about the internal structure of the Earth
Because the speed of the seismic waves depends on density, we can use the travel-time of seismic waves to map change in density with depth and show that the Earth is composed of several layers.. This brittle, outermost layer varies in thickness from about 25 to 70 km under continents and from about 5 to 10 km under the oceans
What is a fault and what are the different types? [10]
A fault is a fracture or zone of fractures between two blocks of rock. Faults allow the blocks to move relative to each other
Faults may range in length from a few millimeters to thousands of kilometers. Most faults produce repeated displacements over geologic time
The fault surface can be horizontal or vertical or some arbitrary angle in between.. Earth scientists use the angle of the fault with respect to the surface (known as the dip) and the direction of slip along the fault to classify faults
Understanding plate motions [This Dynamic Earth, USGS] [11]
Scientists now have a fairly good understanding of how the plates move and how such movements relate to earthquake activity. Most movement occurs along narrow zones between plates where the results of plate-tectonic forces are most evident.
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.. Perhaps the best known of the divergent boundaries is the Mid-Atlantic Ridge
The rate of spreading along the Mid-Atlantic Ridge averages about 2.5 centimeters per year (cm/yr), or 25 km in a million years. This rate may seem slow by human standards, but because this process has been going on for millions of years, it has resulted in plate movement of thousands of kilometers
Transform Plate Boundaries [12]
Where tectonic plates slip horizontally past one another, lithosphere is neither created nor destroyed. Instead, blocks of crust are torn apart in a broad zone of shearing between the two plates
The grinding action between the plates at a transform plate boundary results in shallow earthquakes, large lateral displacement of rock, and a broad zone of crustal deformation.. Perhaps nowhere on Earth is such a landscape more dramatically displayed than along the San Andreas Fault in western California
Virgin Islands is located on another transform plate boundary, where the Caribbean Plate is sliding past the oceanic part of the North American Plate.. Tomales Bay is the surface expression of the San Andreas Fault, seen in the photo below

Earthquakes [14]
Any trembling of earth’s surface that follows a release of energy in the earth’s crust, generated by a sudden dislocation of a segment of crust, or by a volcanic eruption, or at times by manmade explosions, is defined as an Earthquake (Pakiser 1991; Abbot 1998; Bolt 1999)..

10.4 Plates, Plate Motions, and Plate-Boundary Processes – Physical Geology [16]
10.4 Plates, Plate Motions, and Plate-Boundary Processes. Continental drift and sea-floor spreading became widely accepted around 1965 as more and more geologists started thinking in these terms
The major plates are Eurasia, Pacific, India, Australia, North America, South America, Africa, and Antarctic. There are also numerous small plates (e.g., Juan de Fuca, Nazca, Scotia, Philippine, Caribbean), and many very small plates or sub-plates
Rates of motions of the major plates range from less than 1 cm/y to over 10 cm/y. The Pacific Plate is the fastest at over 10 cm/y in some areas, followed by the Australian and Nazca Plates
