1 Volcanic Landforms

2 Landforms From Lava and Ash
Shield Volcanoes Cinder Cone Volcanoes Composite Volcanoes Lava Plateaus Calderas Soils

3 Shield Volcanoes Formed from lava flows Wide Gently-sloped Mountain
Low-viscosity lava

10 Cinder Cone Volcanoes Formed from pyroclastic flows Steeply-sloped
Cone-shaped Hill or small mountain High viscosity magma

17 Composite Volcanoes Formed from both lava flows and pyroclastic flows
Layers of pyroclastic material and lava Gently sloped base and steep peak Mountain Snow on peak all year long

24 Lava Plateaus High, level areas from lava flows
Lava flows out of cracks Low viscosity “Floods” of lava

28 Caldera Huge hole left by the collapse of a volcanic mountain
Fills with water

33 Soils Volcanic material is loaded with minerals
Very fertile (able to support plant growth)

35 Landforms From Magma Volcanic Necks Dikes Sills Batholiths
Dome Mountains

36 Volcanic Necks Leftover pipe from an eroded volcano

40 Dike Magma intrusion that cuts through rock layers
Can be thick or thin

41

42

43

44 Sill Magma intrusion that lies parallel with rock layers
Can be thick or thin

48 Batholith HUGE block of cooled magma that can cover huge amounts of area Gets lifted up through plate tectonics

51

52 Dome Mountain Magma cools underground Gets lifted up Looks like a dome

56 Geothermal Activity Hot Springs Geysers Geothermal Energy

57 Hot Springs Water heated by magma Rises to the surface of the Earth

58

59

60 Geyser Hot spring that has a plugged up vent/opening Traps the gas
Causes the water to explode..

61

63 Geothermal Energy Water heated by magma Water trapped Turns turbine
Makes energy
