1)how can scientists use a seismograph to determine the density and depth of earth's layers? 2) describe at least two geological events that can occur at a divergent boundary. type your answer in the box.

 

Q.) Describe at least two geological events that can occur at a divergent boundary.

A.)Most active divergent plate boundaries occur between oceanic plates and exist as mid-oceanic ridges. Divergent boundaries also form volcanic islands which occur when the plates move apart to produce gaps which molten lava rises to fill.

Hope this can help!!! 

Gallium melts near room temperature and has one of the largest  liquid  ranges of any metal, so it has found use in high temperature thermometers.
