Document Summary
Ocean trench - means subduction - which means convergent - islands means ocean - ocean crust which means the answer is convergent boundary between 2 plates of oceanic crust with andesitic magma. Mid ocean ridge - volcanoes no t a cause no trench or subduction being shown. D there is a trench and there is a continent next to the ocean, if we ocean continent convergent boundary the ocean subducts which means the volcanoes will form on the land so c has volcanoes. Los: what is an earthquake why do they happen. Seismic waves - what are p waves and s waves , how do we use this info to explain properties to find an epicenter, how to we explain magnitude scales. Earthquake damage - what are the mechanism of damage and what results in more casualties. Earthquake - a rapid release of energy in the form of seismic waves due to tectonic stresses that causes rock to break.
