Rocks are heated underneath the crust then pushed out through a volcano or the oceanic plate. The rock substance that becomes the crust will deposit back underneath the crust. All of the process can be credited to the dynamic nature of Earth.
- Crust - cool, lightweight, brittle, which floats on top of mantle. It is the outer layer of earth. Tectonic processes reshape continents and also cause earthquakes - Tectonic plates- plates caused by convection currents in the mantle that causes earthquakes. - Ocean basins form where continents crack and pull apart. - Magma – is molten rock
The Connecticut river valley was also formed from many rifts and faults that had developed. A rift valley is a region of lowland that forms where tectonic plates move apart, which is how the river valley was formed. On the other hand, the plate tectonics also formed the Appalachian mountains. The Appalachian mountains were formed by convergent boundaries, which is when two plates collide. The
The first wave hardly killed anyone, but it killed all technology, electricity, and only a half a million people. The second wave caused not so natural, natural disasters. Metal rods were dropped from the top of Earth's atmosphere which caused tsunami waves and earthquakes. These wiped out many coastal cities, where
The American Revolution was a war of principles fought between the Loyalists and the Patriots. The Loyalists believed that they should stay loyal to the king because they didn't want to go into war. They didn't want to lose their fortune or businesses because if the Patriots won they would lose it all. Moreover, the Patriots fought for the principle of freedom. They fought for their rights.
A tsunami is a series of great sea waves caused by an underwater earthquake, landslide or volcanic eruption. A tsunami is a series of many waves known as wave trains. A tsunami can also be generated by a giant meteor. Most tsunamis are known to be formed by underwater earthquakes.
Earlier that day one of the volcanoes erupted right into the sea, which made the God of the seas frustrated and irritated. As a result of that he created tsunamis because of his frustration and made sure it went over the volcano. Of course that got the God of volcanoes frustrated. It was even worse considering that the God of volcanoes was a hot head.
They are also far out at sea, like rogue waves. They start in the depths of the ocean, then come inwards to land. In addition, they are made on the ocean floor. The text says, “Tsunamis are caused by landslides, volcanoes, or earthquakes that occur on the ocean floor.” (Sanborn 61) Tsunamis are also caused by icebergs falling off, meteorites hitting the ocean surface, and other natural
A storm surge is the rising of the sea as a result of atmospheric pressure changes and wind associated with a storm. Storm surges usually result in flooding in
The Japanese and Alaskan Tsunami and Earthquake. Earthquakes have been occurring for many years, they are known for their massive destruction and life-threatening motives. Many earthquakes occur on land, but they also can happen on the sea floor. When the ocean floors tectonic plates shift, pressure is released and creates an energy that sets of the waters in wave like motion. The wave will barely rise out at sea, but it does travel at the speed of a flying jet.
The California earthquake of April 18, 1906 ranks as one of the most significant earthquakes of all time…. a foreshock occurred with sufficient force to be felt widely throughout the San Francisco Bay area.... Violent shocks punctuated the strong shaking which lasted some 45 to 60 seconds. The book Dragonwings says, Wood and stone and brick and the very earth became fluidlike…. The whole world had become unglued….
They have the same impact like secondary hazard. They are tsunamis, secondary hazard, that causes after the earthquake, tsunami had killed a lot of people and destroy area around there. The effect for Valdivia earthquake are too big so they’re traveled across to the Pacific Ocean and traveled along to the southern Chile, Hawaii, Philippine, Japan and etc, with the speed are over than 200 miles per hour. While the effect for Alaska is also big, that why this incident which is caused tsunami and massive landslides are also affect a lot in Canada to Hawaii.
The area in Canada that is more likely to be affected by a major earthquake (megathrust) is the coast of British Columbia. In addition to the coast of British Columbia, the St. Lawrence, Ottawa River Valleys, and a few areas in the northern territories are likely to have earthquakes. The area British Columbia is in danger because the border is along the mark where the Pacific, the Juan de Fuca and the North America join. The earthquake occurs when the 3 plates rub against each other. The Juan de Fuca plate is shifting east under the North America plate, a few centimeters each year.
These two plates push and shove each other causing small tremors throughout which can cause landslides,volcanic eruptions and once in a couple years, quakes with devastating results. The strongest earthquake recorded occurred in 1991 with a measure of 7.6 on the Richter scale. This earthquake left 4 dead and buildings as well as bridges and road were completely destroyed. If another Earthquake occurs, the coastal cities would be the most affected ones as they are closer to the plates.
The Tohoku Earthquake was the most powerful earthquake recorded to have hit Japan. The earthquake was a magnitude 9.0 off the coasts of Japan that occurred at 2:46pm on Friday 11 March 2011, which triggered a powerful tsunami that reached the height up to 10.4 meters. A Japanese National Police Agency reported 15,889 deaths, 6,152 injured, and 2,601 people missing, 127,290 buildings totally collapse, 272,788 buildings half collapse, and another 747,989 buildings partially damaged. The Tohoku earthquake and tsunami caused severe structural damage in northeastern Japan, including heavy damage to roads, railways and dams, not to mention fires in many areas. It was the toughest and the most difficult crisis in Japan after the World War 2 leaving
