After reading the fact file, your pupils … There are different types of faults: reverse faults, strike … California has tens of thousands of earthquakes every year because it lies at the boundary of two tectonic plates. Moreover, numerous undersea volcanoes are long linear ridges with aspect ratios of 20 or more. These plates can be subducted, colliding, or sliding beside each other as they move around the earth. New Zealand lies on the boundary of the Pacific and Australian tectonic plates, so earthquakes happen here every day. A tsunami (/(t) s uː ˈ n ɑː m i, (t) s ʊ ˈ-/ (t)soo-NAH-mee, (t)suu-; from Japanese: 津波, lit. Supercontinents signify self-organization in plate tectonics. The Ring of Fire includes the Pacific … However, a strong, damaging earthquake can happen at any time, and can be followed by aftershocks that continue for a long time. Children can develop their independent reading skills while reading about the earth’s crust, seismographs, and more. These two plates are slowly sliding past each other at a speed of about 5 centimeters (2 inches) every year. Intro- when comparing different tectonic hazard events it can be seen that some can be seen have much larger costs than others, as well as they type of costs varying between different events for a variety of reasons. The tectonic plates move apart at approximately 2.5 centimetres a year and have done for millenniums. There are three main tectonic movements: extensional, transform, and compressional, all of which result in different types of earthquakes. Each tectonic plate is free-floating and can move independently. Earthquakes and volcanoes are the direct result of the movement of tectonic plates at fault lines. Most are too weak, too deep, or too far offshore for us to notice. The Earth's surface is split into a number of plates which fit together like a giant jigsaw puzzle, these are known as tectonic plates. The upper mantle actually moves large areas of crust, called tectonic plates, very slowly. The collision of tectonic plates can result in earthquakes, volcanoes, the formation of mountains, and other geological events. The earth’s crust is divided into plates that are made up of the original rocks of the planet. Many volcanoes appear in chains, perhaps associated with mantle plumes, there are many more that do not fit this simple model. The rest of the plates carry on moving, which leads to increased pressure on the locked section. This earthquake reading comprehension (in PDF format) is a fantastic tool for teaching children all about earthquakes. When they do, they form faults. The Earth's lithosphere is extremely active, as continental and oceanic plates constantly pull apart, collide and scrape alongside each other. These features suggest that the plates are not exactly ridged as predicted by the simple plate tectonic theory. Ideas for further research are also included, meaning your pupils could go and do some research of their own. Tectonic plate movements are a significant reason why each country in the world is different. Note that some plates run under the ocean, and the continents as defined by geography. Faults often occur at and near the boundary of large tectonic plates because the plates are moving in different directions. They bump into one another or may even slide past each other. Eventually, the locked section succumbs to the pressure, and the plates move past each other rapidly. Lava fields fill the valley, from magma that welled up as the continents spread, and the whole area is littered with ravines, ripped open by centuries of earthquakes. The term fault is used to describe the boundary between tectonic plates. The effects of this movement are very clear within the park. 'harbour wave', pronounced [t͡sɨᵝna̠mʲi]) is a series of waves in a water body caused by the displacement of a large volume of water, generally in an ocean or a large lake. Watch the video below. There are four types of plate boundaries: Divergent boundaries -- where new crust is generated as the plates pull away from each other. Most are too weak, too deep, or too far offshore for us to notice. Most of the … Faults can also occur within a … New Zealand lies on the boundary of the Pacific and Australian tectonic plates, so earthquakes happen here every day. Continental plates are tectonic plates that lie under surface land masses. However, a strong, damaging earthquake can happen at any time, and can be followed by aftershocks that continue for a long time. When tectonic plates move, they can form volcanoes, mountains, or earthquakes. The Ring of Fire (also known as the Pacific Ring of Fire, the Rim of Fire, the Girdle of Fire or the Circum-Pacific belt) is a region around much of the rim of the Pacific Ocean where many volcanic eruptions and earthquakes occur. The Ring of Fire is a horseshoe-shaped belt about 40,000 km (25,000 mi) long and up to about 500 km (310 mi) wide.. Tectonic plates are those slabs of mantle and crust that, in their epochs-long drift, rearrange the earth’s continents and oceans. Nearly all earthquakes occur on faults, features in the Earth where rocks move past each other. Convergent boundaries -- where crust is destroyed as one plate dives under another. A convergent plate boundary is a location where two tectonic plates are moving toward each other, often causing one plate to slide below the other (in a process known as subduction). Over the past ~2 billion years, three major supercontinents have been identified, … Tectonic plates are parts of the planet's crust that lie far below the sea around the world, and there are two types of plates: continental plates and oceanic plates. -One of the main reasons some tectonic hazards are more costly is the physical characteristics of the actual hazard event itself. As the mantle within the earth’s crust moves, the plates also begin to move and start pulling away from each other. There are a total of seven major tectonic plates that make up our planet. Most movement occurs along narrow zones between plates where the results of plate-tectonic forces are most evident. Tectonic plates are constantly moving slowly, but sometimes friction between them causes them lock together and become unable to move. The 7 Major Tectonic Plates.
