A) The mitral valve separates the right atrium from the right ventricle. B) The tricuspid valve divides the left atrium from the left ventricle. C) Aortic and pulmonary valves control the flow of blood into the heart.
In addition to the damage caused directly by seismic vibrations, list three other types of destructive events that can be triggered by earthquakes. Fire, Land slide, Tsunami 6. Describe the composition and physical properties of the crust. Crust is thin, rocky, & outer layer of Earth.n addition to the damage caused directly by seismic vibrations, list three other types of destructive events that can be triggered by earthquakes.

This causes earthquakes such as the Koyna earthquake in Maharashtra. The shock waves through rocks set up by the underground testing of Atom bombs or Hydrogen bombs may be severe to cause earthquake. Effects of Earthquake Destructive Effects: Earthquake causes dismantling of buildings, bridge and other structures at or near epicenter. Many men and animals are killed or buried under collapsed houses. Rails are folded, underground wires broken. Fire breaks out inevitably in large towns. Earthquakes originate sea waves called Tsunamis. Earthquakes result in the formation of cracks and fissures on the ground formation. The earthquakes cause landslides and disturb the isostatic equilibrium. Landslide due to earthquake may block valleys to form lakes. Constructive Effects: Sometimes the earthquakes cause formation of hot springs which are very useful to people.
