If we know how they break, it can help us understand their behavior and perhaps can predict many types of natural hazards which can probably save structures or even 4 our lives. Do you know that rock breaks? Well, they do. Rocks are subjected to several kinds of stress somehow similar to stress that people feel on a bad day. Stress is defined as the force that could create deformation on rocks their shape and volume. Rocks break from stress. Stress as defined above, can weaken a structure. There are different kinds of stress that rocks experience. Lithostatic stress: Rock beneath the earth surface experiences equal pressure exerted on it from all directions because of the weight of the overlying rock. It is like the hydrostatic stress (water pressure) that a person feels pressing all over his body when diving down deep in the water. Differential stress: In many cases, rock may experience an additional unequal stress due to tectonic forces. These are the three types of differential stress: Tensional, Compressional and Shear stress (see Figure1). a. Tensional stress (stretching). This is when a rock is stretched apart or pulled apart. Where crustal plates diverge, rocks are pulled apart. b. Compressional stress (squeezing). This is when a rock is pressed, squeezed, or pushed together. Where crustal plates collide, rocks are compressed or pushed. c. Shear stress. This is a result in slippage and translation. With shear stress, the rock is being pulled in opposite directions. Source:http://geology.isu.edu/wapi/EnvGeo/EG2_earth/EG_mod_2_prt1.htm Figure 1. Three types of differential stress Unequal pulls and pushes on the rocks from different directions may become greater than the elastic limit of the rocks, hence, rocks may be deformed as what you have predicted in Activity 2. When rocks are deformed, they say it is under strain. A strain is a change in size, shape or volume of a material rock. Deformation includes faulting of rigid rocks and folding of rocks that can be bent. Rocks respond to stress differently depending on the pressure and temperature and mineralogical composition of the rock. The ability of the rock to handle stress depends on the elasticity of the rock. There are two types of rock deformation, the elastic and brittle or fracture deformation as seen in the figure below. 5  Source:https://www.tulane.edu/~sanelson/eens1110/deform.htm Figure 2. Deformation of Rock 2 Types of Rock Deformation 1. Elastic deformation: For small differential stresses, less than the yield strength, rock deforms like a spring. It changes in shape a very small amount in response to the stress. The deformation is not permanent but rather reversible. The rock can return to its original shape. 2. Brittle deformation or Fracture: Near the Earth’s surface rock behaves in its familiar brittle fashion. If a differential stress is applied that is greater than the rock’s yield strength, the rock fractures. Fracture us an irreversible strain wherein the rock breaks. It should be noted that part of the rock that did not break springs back to its original shape. This is termed as elastic rebound. Elastic rebound is what causes earthquakes. The breaking of rock is due to low pressure and temperature that are experienced near the earth’s surface. Such irregular cracks can produce fractures such as joints and faults. Brittle rocks tend to fracture when rock is subjected to differential stress. The breaking of rock is due to low pressure and temperature that are experienced near the earth’s surface. Such irregular cracks can produce fractures such as joints and faults. Joints are fractures in rocks that show little or no movement at all. The orientation of the joints can be described as strike and dip and are from as a result of tensional stress acting perpendicular to the orientation of the produced joint on a brittle rock. They provide pathways for water and thus promote chemical weathering. On the other hand, faults are extremely long and deep break or large crack in a rock as a result of continuous pulling and pushing. There are different types of faults, Dip-slip fault, strike-slip fault and ductile formation. Different Types of Faults a. Dip-slip fault or normal fault occurs when brittle rocks are stretched-tectonic tensional forces are involved and the movement of blocks of rock is mainly in the vertical direction (sinking and rising). For dip-slip faults, the block lying on top of the fault surface is referred to as the hanging wall while the one below is referred to as the footwall. Normal faults tend to dip about 600. The hanging wall has moved downward relative to footwall. Normal faults are the chief structural components of many sedimentary rift basins like the North Sea where they have major significance for hydrocarbon exploration. 6  b. Strike-slip fault occurs when brittle rocks are sheared (the opposing tectonic forces are at right angles to compression and tension directions) and the movement of blocks of rocks is chiefly horizontal direction. If the far side of the fault moves to the left relative to an observer it is called “sinistral strike- slip fault” (left-lateral). If the far side of fault moves to the right relative to an observer is called “dextral strike-slip fault (right-lateral). c. Ductile deformation: Rocks buried deep within the Earth’s crust behave differently when subjected to differential stress. It is impossible to produce fracture in rocks the way it is at the Earth’s surface. Rocks become thicker under compressional stress and thinner under tensional stress. Rock layers tend to bend an go out of shape. The high temperature condition makes a rock softer, less brittle and more ductile. Ductile deformation is an irreversible strain which means that the rock cannot go back to its original condition; instead it is changed into a new shape. When rocks deform in a ductile manner, instead of fracturing to form faults or joints, they may bend or fold and the resulting structure are called folds. Folds are promoted by high temperature and pressure at great depth. There are several kinds of folds: monoclines; synclines and anticlines. Kinds of Folds a. Monoclines are the simplest types of folds. It occurs when the horizontal layers are bent upward so that the two limbs of the fold are still horizontal. b. Synclines are fold structures when the original rock layer have been folded downward and the two limbs of the fold dip inward toward the hinge of the fold. c. Anticlines are fold structures formed when the original rock layers have been folded upward and the two limbs of the fold dip away from the hinge of the fold. Now that you know how rocks behave under stress and how they respond to stress and the corresponding structures being made as a direct result of their response to their stress, let us talk about seafloor spreading. Are you ready now? Buckle up and let us enjoy. When you go on vacation, you travel either on land or by air. In both cases, you can see different shapes of the Earth’s surface that amaze you without a doubt. You can see a single mountain or rolling mountains, vast plains, deep valleys, inviting shorelines, beautiful shapes of islands and many more. But what do you think have caused these features? Continental Drift refers to the movement of the Earth’s continents relative to each other, appearing to “drift” across the ocean bed. The thought that continents might have drifted was first speculated by Abraham Ortellius in 1956 but it was Alfred Wegener (1880-1930), a German meteorologist who fully developed the concept. He put out his ideas in his book entitled “The Origin of Continents and Oceans. He presented the evidences he collected from different scientific fields to support his theory. He said the continents were once joined together in a one large 7 landmass called “supercontinent” also known as Pangea (meaning all land), which was formed by a series of continental collisions that began in the late Paleozoic and continued until the early part of the Mesozoic era. Pangea is believed to have been a C-shaper landmass that spread across the equator. It then broke apart beginning in the late Triassic and early Jurassic of the Mesozoic era. The part that lies in the Northern hemisphere is Laurasia. It includes most of the present-day North America, Greenland, Europe and Asia. Gondwana (originally Gondwanaland) lies in the southern hemisphere. It includes most of the present-day South America, Africa, India, Australia, and Antarctica. Laurasia and Gondwanaland were separated by an ocean called Tethys, which is an east-west trending ocean that no longer exist today. North America then drifted toward the northwest. Eurasia rotated clockwise before it moved northward. Africa rotated counterclockwise and drifted eastward, while South America drifted westward. India was separated from Antarctica and Africa, then drifted northeast and then collided whit Asia and yielded the Himalayan mountain range along the former Asian continental shelf. Australia, was once joined to Antarctica, separated and moved eastward. Source:https://geology.com/articles/supercontinent.shtml Figure 3. The Evolution of Pangaea The Pangea breakup lead to an increase in seaways and shorelines, which may have affected the diversification of terrestrial plants and animals by creating several isolated continental regions. In the 1960’s, Harry Hess, an American geophysicist theorized that the sea floor is a hundred million years younger the continents. He suggested that not only the continents were moving but the sea floor was also moving. This idea was revolutionized the geologic thought in latter part of the 20th century. Hess’ explanation of sea floor spreading was mantle convection. It has been understood that the earth’s mantle exhibits a solid-like behavior known as “plasticity”. It was until the development of highly sophisticated seismic recorders and precision depth recorders that scientist found out in the 1960s the discovery of mid-oceanic ridge or mountain chain on the ocean floor bisecting the Atlantic Ocean, together with its rift that runs along its length. The ocean floor has been found to be moving away from the rift, and the rift continuously emits volcanic materials from below. Hot magma rises because it is less dense that the surrounding magma and when it reaches the surface it cools and solidifies becoming the sea floor. As more magma rises, the present sea floor is pushed aside. At plate boundaries, the cold and denser rock sinks and melts, becoming magma once again. This shows that there is a recycling process. Seismic studies confirm that oceanic crust is indeed sinking into the trenches. This mantle convection is the driving force for the motion of the sea floor and the 8 continents. Magma continuously flows out as lava and fills the rift. It hardens and pushes the old hardened lava on both sides and moves away from the rift. Both sides of the ridge move away from the rift as magma continues to flow out. The movement of crustal rocks away from the ridge causes the sea floor to spread. This phenomenon is known as seafloor spreading. Paleomagnetism is a proof that support sea floor spreading. It tells us how far from the poles rocks were when they were formed by looking at the angle of their magnetic field.
