PPT-1.3: Types of Volcanoes Describe basic shapes of volcanoes.

Compare the features of volcanoes Describe the stages in volcano formation What are Volcanoes Volcanoes are vents through which molten rock and gas escape from a magma chamber Volcanoes can differ. Lava Video. Volcanoes, magma, and lava. Volcanoes are weak spots in the crusts where molten material, or magma, comes to the surface.. When magma reaches the surface it is called lava.. The lava released during volcanic activity builds up Earth’s surface, it is a constructive force.. Chapter 5. Rigid Earth to Plate Tectonics. Learning Objectives. Know the different types of volcanoes and their associated features. Understand the relationship of the volcanoes to plate tectonics. Know what geographic regions are at risk from volcanoes. Frequency and Quantity. There are ~ 550 historically active volcanoes. About 60 erupt annually. The majority are 1) at the edge of continents and 2) underwater. Dormant volcanic cone in Japan. What causes volcanoes?. Martin . Ménégoz. , Francisco . Doblas. -Reyes, . Virginie. . Guemas. , . Asif. Muhammad. EC-Earth Meeting, Reading, May 2015. Reading, May 2015. 2. Introduction. Major eruptions bring large amounts (Tg) of particles in the stratosphere.. Volcanism is mostly focused at plate margins. Pacific Ring of Fire. This map shows the margins of the Pacific tectonic plate and surrounding region. The red dots show the location of active volcanism. Notice how the majority of the volcanism is focused in lines along the plate boundaries? For this region is the area known as the “Pacific Ring of Fire”.. . T. his . is a map of Pompeii's famous volcano called . Mount . Vesuvius. . How many volcanoes are there in the . world?. There are around 1510 'active' volcanoes in the world.

Know all the different parts of a volcano.. Warm Up. Why do you think magma rises? Consider an ice cube floating at the top of a glass of water. Objective:. SWBAT. Describe at least two of the three types of volcanoes and how they form. Agenda:. Project 3: August 27, 28, 31. Underlying Shapes. Day 1: Warm Up. In your sketch / notebook, write “Underlying Shapes” at the top of the page.. Draw a horizontal line in the middle of the page.. Volcanism is mostly focused at plate margins. Pacific Ring of Fire. This map shows the margins of the Pacific tectonic plate and surrounding region. The red dots show the location of active volcanism. Notice how the majority of the volcanism is focused in lines along the plate boundaries? For this region is the area known as the “Pacific Ring of Fire”.. Where are the major zones of volcanism?. What are the parts of a volcano?. How do volcanic landforms differ?. Copyright © McGraw-Hill Education. Volcanoes. Review. convergent. New. volcanism. hot spot. What are volcanoes?. Does anyone know what a volcano is?. A volcano . is a landform (usually a mountain) where . liquid rock . erupts through the surface of the planet. .. The name "volcano" has its origin from the name of Vulcan, a god of fire in Roman mythology.. . . Cause. most volcanoes are formed when two of Earth’s plate collide. the collision drives one of the plates under another . the plate that is under the other one begins to melt-->this melted rock is known as magma.
