Pictures based on satellite images highlight the features at the 1. �1 Living with earthquakes and volcanoes Earthquakes and volcanic eruptions can have disastrous effects, especially if they happen in places where many people live. Understanding the causes and effects of earthquakes and volcanoes can help to reduce their effects on people and environments. Given that all of the Earth’s surface is a collection of plates. There are no parts of the Earth’s crust that is not part of a plate. There are continental plates, such as the North American plate, the Eurasian plate, the South American plate, the Plate movement causes the buildup of tremendous quantities of energy in the rock. When the energy is released, it produces vibrations that travel through the rock, leading to earthquakes. During earthquakes, faults, or giant cracks, are produced the pressure of the moving rock. Earthquakes and volcanoes occur along the edges of the plates. Molten material moving under the earth’s crust is called magma. When magma comes to the surface of the earth it is known as lava. The molten rock that reaches the surface of the earth is called The volcanoes and earthquakes are associated with each other as every volcanic activity takes place shaking and breaking the weak crust 1 Earthquakes 2 Volcanoes Lab Disruptive Eruptions 3 Earthquakes,Volcanoes, and Plate Tectonics breaking and moving. Such breaking, and the movement that follows, causes vibrations that move through rock or other earth materials. If they are large enough, these vibrations are felt as The two plates making up the San Andreas Fault are different from those in the Cascadia Subduction Zone, however, in that they slide past another, much like two cars moving very slowly in opposite directions on a freeway, in what scientists call a "slip. A volcano is a vent through which molten rock escapes to the earth’s surface. Unlike other mountains, which are pushed up from below, volcanoes are built surface accumulation of their eruptive products—layers of lava flows, ash flows, and ash. When pressure from gases within the molten rock becomes too great, gases drive the molten Volcanoes, also, do not always seem to erupt through the seams of these plates. The Hawaiian Islands seemed to have been formed a “hot spot,” burning its way many times through the middle of a north-western-moving Pacific plate as it passed. Many of the volcanic sites in the north-western U.S., however, are near the intersection of plates. Under the right conditions, when plates are pushed together or pulled apart, volcanoes are created, which is why they tend to occur in the same place as earthquakes. When tectonic plates spread apart from each other, hot magma rises up and fills the space between. Earthquakes are when the plates move too much, and volcanoes hapen when there is a large gap in the plates. The magma/lava comes through … 2. Remind students that they have studied earthquakes and volcanoes. Explain that earthquakes and volcanoes help scientists (geologists) to study how the Earth works. Through looking at patterns in where earthquakes and volcanoes occur, they have found that the Earth's surface seems to move as large masses of the rock, which are called plates. 3.

BBC Volcano Live 3 of 4 Volcanoes, Earthquakes and Tsunamis Chapter 10 Volcanoes Our early ancestors created stories to explain volcanic eruptions. For example, it was thought that the volcanic may leave the conduit moving sideways along weaknesses between rock layers. This sideways movement of magma forms a Conditions for making magma. Conditions that melt rock Changes in pressure Rock under Volcanoes can also have long-term effects on the climate, making the world cooler. Fast-moving lava can kill people and falling ash can make it hard for them to breathe. They can also die from famine, fires and earthquakes which can be related to volcanoes. Indonesia has the most active volcanoes in the world and remains one of the most dangerous areas. 10% of the earth’s active volcanoes can be found in Japan. Over 20% of the earth’s active volcanoes are underwater. The volcanic pumice rock is the only known rock that can float in water. Volcanoes and earthquakes are both found on plate boundaries. However, there is a difference between the two since volcanoes are never found on conservative and divergent boundaries because there is no change in crust to allow more magma (molten rock) to be made. Volcanoes vary quite a bit in their structure - some are cracks in the earth's crust where lava erupts, and some are domes, shields, or mountain-like structures with a crater at the summit. Magma is molten rock within the Earth's crust. When magma erupts through the earth's surface it is called lava. Lava can be thick and slow-moving or thin Magma and Plate Tectonics - Magma is fluid molten rock that exists under the Earth's crust. Learn about magma and find out how plate tectonics can cause volcanic activity. The red triangles mark active volcanoes and the yellow dots show recent earthquakes. If the two plates are moving … A) Would cause minor damage to buildings B) Would cause major damage C) Would not be felt, but could be detected a seismograph D) Would shake walls and knock things off tables In this section we focus on two types of hazards, earthquakes and volcanoes, that can be explained the process of plate tectonics. Plate tectonics offers a global framework for the occurrence of the planet’s earthquake and volcano hazards. The Moving Story of Plate Tectonics AP Smoke and ash from rock cools and hardens under the Earth’s surface. The ocean floor is basalt rock, Volcanoes and earthquakes are among the most I decided to do my semester paper on the ring of fire. The reason I chose that specifically is that we talked much about earthquakes and volcanoes and those are two major things that happen on the ring of fire along with a few other natural disasters that are triggered.

The rock has nowhere to go so it moves upwards making a mountain Rock Moves upwards 10. Mountains are made two plates coming together. The rock has nowhere to go so it moves upwards making a mountain This is called mountain building Rock Moves upwards 11. Valleys and trenches are made plates moving apart. 12. Earthquake activity around a volcano can provide valuable information. An eruption can be preceded hundreds of small earthquakes know as earthquake swarms. Earthquakes also can indicate that magma is moving beneath a volcano. However, eruptions can occur with no perceivable change in … A series of Powerpoint lessons and activites on Plate Tectonics including: the structure of the Earth; Shield and Composite volcanoes, A case study of Montserrat; how earthquakes occur and investigating the effects of the 2004 Boxing Day Tsunami in the Indian Ocean. Magma, Lava and Volcanoes. Magma is molten (melted) rock beneath Earth's surface. Lava is molten (melted) rock that reaches Earth's surface. A volcano is a mountain made of lava, ash, or other materials from eruptions that occur at an opening in Earth's crust Rarely, very large landslides can occur on the flanks of volcanoes, called sector collapse. Debris avalanches can result, which are fast-moving slurries of rock, water and debris. Lava Molten rock that has reached the Earth's surface and been thrown out of or has flowed from a volcano or volcanic vent. One of these mid-ocean ridges, the Mid-Atlantic ridge, is spreading apart making the Atlantic Ocean wider. As the two plates move the mantle melts, making magma and lava fill the void with newly formed rock. The bottom of the Atlantic Ocean is filled with some of the "youngest" crust on Earth. 81% of earthquakes occur along the Pacific Ring of Fire. Despite the slow movement of plate tectonics (just 5-10 cm every year), they release a tremendous amount of energy. For example, Indonesia is known for having one of the most active chain of volcanoes in the world. When volcanoes erupt with little or no warning, they are extremely dangerous. Molten lava flows quickly down the slopes, dangerous gases are released, and they can also trigger earthquakes and tsunamis. Sometimes volcanoes don’t simply spill forth lava and rock, but actually explode. This can lead to … Learn science guide volcanoes earthquakes with free interactive flashcards.
