Volcanos are one of nature's grandest spectacles. Now you can learn all about these terrifying geological features with these challenging flashcards.
There are 9 flash cards in this set (2 pages to print.)
1. Print out the cards.
2. Cut along the dashed lines.
3. Fold along the solid lines.
Sample flash cards in this set:
|Shield Volcanoes||Built out of layers of lava from repeated ( non- explosive ) eruptions. Because the lava is very runny, it spreads over a wide area and has gently sloping sides.|
|Cinder Cone Volcanoes||Volcanic cones are made entirely of pyroclastic material from a moderately explosive volcano. The material forms a narrow base, and erodes quickly because the particles are not cemented together|
|Composite ( Stratovolcanoes )||Formed by explosive eruptions followed by quieter outporings of lava. This combination of pyroclastic ( hot, rocky, fragmented ash ) and runny lava created bases that get deeper towards the summit.|
|Volcano||a mountain that forms when molten rock, called magma, is forced to the Earth's surface|
|Lava||magma that flows onto the Earth's surface.|
|Pyroclastic Material||consists of the molten rock fragmens created by explosive volcanic eruptions|
|Magma||Deep underground the driving force that creates volcanoes is hot, liquid rock known as magma that collects in chambers.|
|Vents||The holes in the Earth's crust that magma rises through|
|Crater||The top, central, funnel shaped vent of a volcano.|
