Plate tectonics

Damages were not nearly as serious as it would be today, mostly because Southern California was sparsely populated. The effects of the earthquake were quite dramatic, even frightening. Were the Fort Tejon shock to happen today, the damage would easily run into billions of dollars, and the loss of life would be substantial. On March 10, 1933, a 6.4 earthquake hit the Newport-Inglewood Fault, causing serious damage in long Beach and other communities. The earthquake resulted in 120 deaths and more…

An earthquake is caused by tectonic plates that moves few centimeters per year. The tectonic plates can be oceanic or continental they move mainly because of the gravity but also because the mantle a mixture of rock and melted rock so it move but not as fast as it would move in a liquid. The Sea plates are heavier than the Land plates which is the case of Japan. The tsunami is an earthquake under water but because of the pressure the water will move really fast and it the wave will increasingly…

creation of the motion diverging plates and it is an underwater mountain range which are formed by plate tectonics. It consist of mountains linked together, having a valley running along the spine, and its known as an oceanic spreading center which is in charge of the seafloor spreading. New seafloor is being produced when convection currents rise in the mantle layer which is under the oceanic crust, it then create magma that cools down into basalt where two plates is push away from each other.…

Volcanoes are mountains that can erupt to spew molten rock everywhere. A volcano can be formed in different ways like hotspots or tectonic plates. The tectonic plates can form volcanoes by forming convergent or transform boundaries. A convergent boundary is when two tectonic plates collide into each other, forming mountains. The transform boundaries form mountains when they slide into one another. Hotspots are formed when the magma is forced up to the Earth's surface. Before Mount St. Helens…

beautiful hot magma that flows from the volcano is dangerous and burns everything in its path. Two volcanoes that have always caught my eye is Hawaii’s Kilauea and Japan’s Mount Fujiyama. Both volcanoes are located on an island that was formed due to tectonic plates shifting, furthermore both volcanoes represent different types of volcano forms, however, Hawaii’s Kilauea volcano is still active while Japan’s Mount Fujiyama has not erupted since between 1707-1708. Havelock Ellis once said, “All…

A Hurricane is a tropical cyclone or tropical storm that forms over in the Caribbean Sea, Gulf of Mexico, Southern Atlantic Ocean and the eastern Pacific Ocean. Close to the earth 's surface a cyclone is accompanied by thunderstorms and a circulation of counterclockwise winds. Hurricanes can hit the gulf Mexico and all of the Atlantic Ocean. Every year the Atlantic hurricane season starts on May 15 and will always end on November 30. Hundreds of miles inland and coastlines, hurricanes can cause…

earthquakes, such as plate tectonics and seafloor spreading. Understanding these actions can allow us to have better understanding of the causation of earthquakes. Plate tectonics is the theory that states Earth’s outer shell is divided into several plates that glide over the rocky inner layer of Earth called the mantle. The theory began in the 1950s, as it became the modernized version of continental drift, which had been put forth by Alfred Wegener. The entire earth rests on these plates, as…

The Earth's crust is constantly moving in all directions. The movement of the crust is called plate tectonics. Plate tectonics hasn't been developed very long, only about fifty years. It was founded by geophysicists in the 1960's. The continents fit together in one humongous piece. Which makes it one enormous continent. Wegener found out that there were numerous continents that looked comparable. He thought once in the past that parts of Africa and South America might have been…

Samoan 2009 tsunami report: What caused the earthquake and tsunami? On Tuesday the 29th of September 2009, a huge tsunami hit Samoa – as well as several other islands – and impacted many, leaving a path of destruction. Tsunamis are big waves that are generated from earthquakes, or volcanic eruptions that occur in the ocean. When the waves move inland they gradually gain height as the ocean gets shallow. So, the speed of the tsunami is related to the depth of the ocean. Tsunamis travel very fast…

Define the terms subduction, mid-ocean ridge, and ocean trench and island arc. Subduction is when two tectonic plate’s convergent boundaries come crashing together resulting in one going below the other. This results in the bottom plate to sink into the mantle. Mid-ocean ridge is an underwater mountain ridge that forms when convection currents causes magma to rise where two tectonic plates meet at a divergent boundary. Ocean trench are long narrow depressions on the sea floor as a result most…
