It may be difficult to predict them, but their effects can be reduced through timely response. People have understood the theory of plate tectonics. This means that everyone is always ready for any earthquake, tsunami, or…

Scientists have been able to understand why natural hazards occur and when to warn people about them.
The government understands the timeline for a natural disaster. This enables it to manage its resources to maximize its efforts in assisting people during a natural disaster. A timeline is an elaboration of the occurrences of a particular event. People have understood the different timelines of hazards to employ the required procedures to reduce risks in times of a natural disaster. The government should know the appropriate time to issue warnings about a hazardous event. Warnings should be timely; if they are issued too early and the event fails to occur, people may stop taking warnings seriously.
City planners should issue a hazard watch and warning. A tsunami warning would mean that there are possibilities of tsunami conditions in a specific area. A tsunami watch would mean that there are possibilities of tsunami conditions within 36 hours. Issuing hazard watches and warnings assist people living in a hazard prone area to plan for natural disasters. They should also issue regulations concerning building materials and height. Buildings should be built using strong and flexible materials (steel). Buildings with steel supports are cannot incur as much damage as buildings with heavy, brittle materials (mortar, brick and adobe). These regulations would ensure that people plan for natural disasters (Rafferty, John p. 27).
Plate tectonics has been known to be the cause of natural disasters such as tsunamis, earthquakes, and volcanic eruptions. People have understood the science behind the movements of the layers of the lithosphere. This knowledge has made such events testable and predictable, despite the fact that they are caused by natural disasters. Governments, city planners, and citizens ought to take the necessary measures to reduce the risks of a

The theory states that “the continents had once been joined, and over time had drifted apart in a giant supercontinent called Pangaea.” (Sant, 2010; “Tectonic Plates,” 2011) One of the proofs of the theory is the jigsaw fit that the continents make with those adjacent to it.
It was not until the 1960s that scientists were able to explain the mechanism, finally answering Wegener's problem, which was that solid continental and oceanic plates floated on a molten rock bed. This became known as Plate Tectonic Theory and has become widely accepted by geologists.
It is all about the nature. For comprehending the significance and power of natural disasters, it is quite enough to recollect the nine-magnitude earthquake that has happened in Japan this year. Hundreds of people were killed, millions of buildings and houses were destroyed, and thousands of victims were left without shelters or any means of livelihood.
Scientific observation of the surface of Mars has been greatly limited mostly to visual observations and the findings of remote controlled rovers sent by NASA to retrieve information. It is suspected that Mars may have had an atmosphere, water system, and crust similar to that of Earth.
The assumption of plate tectonics turned out to be generally established by scientists of the 1960s and 1970s era. It transformed our perception of the Earth and combined the Earth sciences, from the learning of paleontology (fossils study) to the science of
rocks that have different composition from their parent rock, since the magma formed during partial melting is less viscous, thus attracts other components which cause it to solidify and form different rocks (Annen & Zellmer, 2008 p49). Rocks are formed of different mineral
The Ural Mountains are just an example of Fold Mountains around the world (Wright, 1977). The plate tectonic theory states that the earth’s crust is covered with tectonic plates on which the continents rest on.
vidently, over this period, many scientists have focused on explaining how the movement of plates has given rise to many of the geographical features. The paper shall discuss the history of tectonic plate theory, and discuss three geologic features. The three features under
