Earth’s Changing Structures SSA Review 5 – Earth’s Changing Structures

Earthquakes What is an Earthquake? Earthquake – the shaking of the Earth’s crust caused by a sudden movement of the Earth’s tectonic plates.

Seismic waves – the vibrations through the Earth caused by the earthquake Carries the energy away from the focus, in all directions through the Earth’s interior, and across the surface.

Tectonic stresses causing Earthquakes Tension – the crust is stretched

Tectonic stresses causing Earthquakes Shearing – the crust is pushed and pulled in opposite directions

Tectonic stresses causing Earthquakes Compression – the crust is squeezed

Most volcanoes form along convergent boundaries (subduction zones) Volcano – an opening on the Earth’s crust where magma erupts onto the surface. Most volcanoes form along convergent boundaries (subduction zones)

Types of Eruptions 1. Quiet eruption – the lava flows gently down the side of a volcano

Types of Volcanic Eruptions 2. Explosive – lava explodes out of the volcano *Pyroclastic flow – eruption that sends out ash, volcanic rocks, and gases Mayon Volcano - Phillipines https://www.youtube.com/watch?v=mIX43uy4Zvg
