A break in the earth crust along which movement occurs is called a ? Best Answer: The answer is 2. fault. That is the break in the crust. When the movement occurs, that is an earthquake. a locked discontinuity is a fault, if it moves you have an Earthquake. It is a fault. volcano. thats not my answer.

High School Earth Science/Stress in the Earth's Crust If the blocks of rock on one or both sides of a fracture move, the fracture is called a fault (Figure 7.14). Earthquakes happen when there are sudden motions along faults. When rocks break and move suddenly, the energy released causes an earthquake. Faults may occur at the Earth's surface or deeper in the crust.

Plate Tectonics A fault is a break in the rocks that make up the earth's crust, along which on either side rocks move pass eachother. Larger faults are mostly from action occuring in earth's plates. A fault line is the trace of a fault, or the line of intersection between the fault line and the earth's surface. Stike-slip faults are vertical (or nearly vertical) fractures where the blocks have mostly moved horizontally.

- As the plates separate along the boundary, the block between the faults cracks and drops down into the soft, plastic interior (the asthenosphere). The sinking of the block forms a central valley called a rift. Magma (liquid rock) seeps upward to fill the cracks. In this way, new crust is formed along the boundary.Earthquakes occur along the faults, and volcanoes form where the magma reaches the surface. Where a divergent boundary crosses the land, the rift valleys which form are typically 30 to 50 kilometers wide.Examples include th e East Africa rift in Kenya and Ethiopia, and the Rio Grande rift in New Mexico.here a divergent boundary crosses the land, the rift valleys which form are typically 30 to 50 kilometers wide.

Earth Science for Kids The Lithosphere. The part of the land that is moving is the Earth's surface called the lithosphere. The lithosphere is made up of the Earth's crust and a part of the upper mantle. The lithosphere moves in big chunks of land called tectonic plates. Some of these plates are huge and cover entire continents.

Crust (geology) In geology, the crust is the outermost solid shell of a rocky planet, dwarf planet, or natural satellite. It is usually distinguished from the underlying mantle by its chemical makeup; however, in the case of icy satellites, it may be distinguished based on its phase. The crusts of Earth, Moon, Mercury, Venus, Mars, Io, and other planetary bodies formed via igneous processes, and were later modified by erosion, impact cratering, volcanism, and sedimentation. Most terrestrial planets have fairly

Slip, Slide, & Collide As the oceanic crust sinks, a deep oceanic trench, or valley, is formed at the edge of the continent. The crust continues to be forced deeper into the earth, where high heat and pressure cause trapped water and other gasses to be released from it. This, in turn, makes the base of the crust melt, forming magma.

- Magma is pushing up from Earth's interior all along this ridge and creating new crust. The same forces that pull the plates apart also allow magma from Earth's interior to come up along the ridges and create new crust. Areas where new crust is created and plates are forced apart are called spreading centers.Although the movement of the plates away from spreading centers is very, very slow (about one inch per year), it has been happening for millions of years. Thus, very small changes have become very large over time.he same forces that pull the plates apart also allow magma from Earth's interior to come up along the ridges and create new crust. Areas where new crust is created and plates are forced apart are called spreading centers.

lithosphere The lithosphere includes the Earth's crust and the uppermost part of the mantle. The lithosphere's thickness varies depending on whether you measure the thin new crust on the ocean floor or the old crust of an established land mass. The Earth's lithosphere is broken into continental plates that move over time. Slight movements in the lithosphere can cause earthquakes when the plates bump against each other. Litho is from the Greek word lithos, meaning stone. Sphere is from the Greek word sphaira, meaning globe or ball.

The Dynamic Earth: Internal & External Forces that Shape Earth's Surface Earthquakes occur when stress builds up in the Earth's crust and causes it to break in a line known as a fault. A fault is a crack in the Earth's crust caused by stress in the surrounding rocks. Stress builds up in the crust for several reasons.

Earthquakes at a Plate Boundary Earthquakes at a Plate Boundary. An earthquake is a sudden motion or trembling in the crust caused by the abrupt release of accumulated stress along a fault, a break in the Earth’s crust. The ‘Ring of Fire’ shows the position of the New Zealand continent within a zone of intense seismic activity around the Pacific Ocean.

How Earthquakes Work The theory, called plate tectonics, is that the Earth's crust, or lithosphere, comprises many plates that slide over a lubricating asthenosphere layer. At the boundaries between these huge plates of rock and soil, the plates sometimes move apart, and magma, or molten rock, comes to the surface, where it's called lava. It cools and forms new parts of the crust. The line where this happens is called a divergent plate boundary.

Faults A fault is formed in the Earth's crust as a brittle response to stress. Generally, the movement of the tectonic plates provides the stress, and rocks at the surface break in response to this. Faults have no particular length scale. If you whack a hand-sample-sized piece of rock with a hammer, the cracks and breakages you make are faults.

Tectonic Puzzle: Why West Africa Didn't Follow South America When this landmass started to split, gashes in Earth's crust called rifts opened up along pre-existing weaknesses. One of these gashes, called the West Africa Rift System, started to tear apart the future Sahara desert. Two more rifts formed along the future boundaries of South America and Africa.Imagine three rift zones, two lined up essentially north-south and one pointing east-west. These alignments are key to explaining why the continents broke apart the way they did, according to a study published March 6 in the journal Geology.he mantle is the hotter layer of rock beneath Earth's crust. The crust often breaks apart at three-pronged junctions, such as the triple rift that formed between Africa-South America, and it's not uncommon for one rift to fail to develop.

- A Broken Lithosphere. The fundamental units of plate tectonics are large pieces of Earth's lithosphere, the outermost rocky layer of the planet that is composed of the Earth's crust and the upper 50 to 80 miles of the next-lower layer, the mantle. The lithosphere is not a uniform mass of rocks.

Crust (geology) The lithosphere is broken into tectonic plates that move, allowing heat to escape from the interior of the Earth into space. The crust lies on top of the mantle, a configuration that is stable because the upper mantle is made of peridotite and so is significantly denser than the crust.

The Earth's Layers Lesson #1 The Lithosphere The crust and the upper layer of the mantle together make up a zone of rigid, brittle rock called the Lithosphere. The Lithospheric Plates The crust of the Earth is broken into many pieces called plates. The plates float on the soft, semi-rigid asthenosphere.

- Lesson Summary. The Earth's crust is split into sections called tectonic plates. Transform boundaries are where two of these plates are sliding alongside each other. This causes intense earthquakes, the formation of thin linear valleys, and split river beds.

Tectonic Plate Motion The process by which the oceanic crust is pulled under the continental crust is called subduction and the zone at which this occurs at the plate boundaries is called the subduction zone. At the subduction zone where the oceanic crust sinks beneath the continental crust a deep oceanic trench or valley is created. These can be many of thousands of kilometres long and 8 to 10 kilometres deep making them the deepest part of the ocean floor.

- The Continental Slide. New crust is continually being pushed away from divergent boundaries (where sea-floor spreading occurs), increasing Earth's surface. But the Earth isn't getting any bigger. What happens, then, to keep the Earth the same size? The answer is subduction. In locations around the world, ocean crust subducts, or slides under, other pieces of Earth's crust. The boundary where the two plates meet is called a convergent boundary. Deep trenches appear at these boundaries, caused by the oceanic plate bending downward into the Earth. Deep below the Earth's surface, subduction causes partial melting of both the ocean crust and mantle as they slide past one another.
