Science Flashcards

Viscosity of lava

resistance to flow- thick and sticky

Gas content

high viscosity its high gas content, low viscosity is low

Shield Volcano

An effusive type of volcano characterized by broad, gentle slopes formed by the eruption of low-viscosity lava that can travel long distances.

Strato Volcanoes

An explosive type of volcano characterized by steep slopes, built up by lots of layers like, lava volcanic ash. they can be dangerous

Crust

outest part, thin solid rock its dark

Mantle

thick layer of hot solid rock- second layer

Inner core

solid ball, very hot

Outer Core

very thick fluid layer- third layer

Litosphere

includes crust and upper mantle

Asthenosphere

soft layer of the mantle that is semi-solid rock, but can bend

P waves

fastest waves that go in a straight line- primary waves

S waves

they travel slower, and travels up and down or side to side
