Volcanoes. 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 18. VOLCANIC Magma Types. Introduction (1)‏. ~ 1,500 active volcanoes on Earth 400 erupted in the last century ~ 50 eruptions per year Most activity concentrated along major plate boundaries Impact risks depend on the types of volcanoes. Introduction (2)‏.

Plate Tectonics and Volcanoes. Earth Science Chapter 18. Volcanoes. Volcanoes Hills or mountains made from hardened magma. Volcanoes. Magma Molten rock that is below the surface of the earth Located in the mantle Forms when rocks melt due to subduction Lava

Volcanic Activity. Inside Earth Chapter 3.2 Pages 93-102. Characteristics of Magma. Force of an eruption depends partly on the amount of gases evaporated in the magma The temperature and the contents of the magma are important factors. Characteristics of Magma.

Volcanic Environments. Volcanic environments are one of the Earth’s most spectacular natural events. Hot molten material from inside the Earth explodes onto the surface and into the atmosphere. It can destroy and build up at the same time. .

Igneous Rocks & Rock Structures. These notes go on pp. 7 & 9 of your Igneous rock INB!!!. Igneous rocks are formed by the crystallization of molten rock ( lava or magma ). Classification. Mineral Composition Texture of Grain Size. Mineral Composition.

Volcanoes. Forces Inside the Earth. What is a volcano?. A volcano is a weak spot in the crust where molten material, or magma, comes to the surface. when magma reaches the surface, it is called lava After lava has cooled, it forms solid rock, building up Earth’s surface.

Volcanoes. What is a Volcano?. A volcano is an opening in Earth’s crust through which molten rock, rock fragments and hot gases erupt. How do volcanos erupt?. A volcano may erupt violently or gently.

Plate Tectonics. What do you notice about the continents when you look at a map of the Earth?. Continental Drift. Hypothesis that all continents were once connected in a single large landmass that broke apart Alfred Wegener (1912) Pangaea (all land) – name of large landmass

1/30 Warm Up. On your green SWOD paper answer this question: Rank the following seismic waves from fastest to slowest: P waves S waves Surface waves. Announcements. Extra Credit turn into black cupboard Finish Roller Coasters/Rube Goldbergs Physics test retakes.

Plate Tectonics. Evolution of the Earth. Cracks in the Earth’s Crust. The crust , when it is solid, acts as a heat insulator for the hot interior of the Earth. The molten material in the mantle, magma , below the crust builds up tremendous heat and pressure.
