lntroduction of earthquakes and volcanics
Answers
Hey Here is your Answer.
Explanation:
Earthquakes are not a geological structure like volcanoes and they do not release magma. They are violent movements of the Earth's crust. However, unlike volcanoes, earthquakes are common to all types of plate boundary. Earthquakes occur as a result of friction and build up of pressure between plates.
earthquakes, essential to explaining how these natural phenomenon occur. The red dots are a symbol for the earthquake epicenters while yellow lines present the plate boundaries (The blue areas is ocean and the green areas is land). It is evident that the vast majority of earthquake locations lie on the plate boundaries. Earthquakes are created through the movements of plates which can differ in several ways, determining the magnitude of the earthquake. Plates move through convection currents which is the movement of magma beneath the Earth's crust, which rises or falls due to variations in temperature. As these move the plates, earthquake occur between two plates generally due to friction.
volcanic eruption in the area, and it is evident that volcanoes much like earthquakes occur along plate boundaries. This is due to an accumulation of magma rising through cracks in the earth's crust. A volcano cone begins to form along with a new magma chamber. The magma chamber continues to accumulate magma until it is shot out of the volcano at either both great or slow speeds. Volcanoes also occur in long narrow belts where clusers of volcanoes form and erupt. An example of this would be the Pacific 'Ring of Fire' which covers the entire Pacific ocean
