the boundaries of the tectonic plates. Tectonic plates were created at mid-ocean ridges and some rift valleys, tectonic plates then were destroyed and sunken deep into the ocean trenches. When a new plate material forms, it is created in ocean ridges where the molten rocks rises from the interior it the hardens. This new plate then gets topped by the oceanic crust, therefore the surface of the crust then becomes the sea floor. The ridges become the extension of the tectonic boundaries. When the solidifying
land. Plate Tectonics The plate tectonic theory was conceived through the initial concept of continental drift. Plate tectonic theory suggests that the Earth’s lithosphere is divided into a number of different ‘plates’. The lithosphere is the outer part of the Earth which consists of the crust and upper mantle. The lithosphere is made up of 10 major plates as
in the south of New Zealand on the North Island. New Zealand has many towns and cities that have houses and buildings close to or on a fault. They built the buildings and houses before they knew about the fault. The Fault starts at Wellington and ends at the Bay of Plenty. The Wellington Fault region has been impacted by earthquakes since the beginning of human settlement. The Wellington Fault is consisted of three sections the Wellington-Hutt
the tension gets released from inside the crust of the earth. Tectonic plates move alongside and past each other but they do not always move smoothly and when they get stuck it causes an earthquake because the pressure builds up then the pressure is finally released (see source 1). This movement from the plates forces waves of energy to come to the surface of the Earth. Plates can also converge into each other, this is when two plates collide and one goes beneath one and creates an earthquake.
New Zealand is made up of two islands (North and South Island) which are located roughly a 1,000 miles Southeast of Australia. The country is relatively small with an area of 103,000 square miles (CIA). There are pros and cons to the country’s small size. The advantage of its size is it will be easier to create brand exposure. In addition, the nation’s small size indicates transportation costs will be significantly lower, compared to other nations. However, the downfall of the country’s size is it
“Volcanic and seismic events are major pieces of evidence towards proving that plate tectonics theory is valid’ Discuss the extent to which you agree with this statement (40 marks) The plate tectonics theory was made by a German named Alfred Wegener. He stated that a single continent existed about 300 million years ago named Pangaea and that it split into two continents of Laurasia in the north and Gondwanaland in the south. Today’s continents were formed by further splitting of the two masses
trenches are commonly found near the Ring of Fire, caused when the ocean floor converges into the earth. The Ring of Fire itself is formed from the result of plate tectonics when lithospheric plates collided into each other. Plates have lots to do with the Ring of Fire. As I stated in the paragraph above, it was created by plate tectonics.
through Japan, and into New Zealand. There are also several active volcanoes in Antarctica. The creation of the Ring of Fire is very interesting too, it is the result of plate tectonics. These are huge slabs of Earth’s crust that fit together like the pieces of a puzzle. These plates can collide, stay apart, or move up right next to each other. The convergent plate boundaries are formed by plates colliding into each other. The heavier plates slide under the lighter plates causing a deep trench in
1960, the world’s largest earthquake struck southern Chile, Hawaii, Japan,the Philippines, eastern New Zealand, southeast Australia, and the Aleutian Islands in Alaska.due to how widespread the earthquake and following tsunami was, the death toll is still unknown. This earthquake was a megathrust earthquake, which was a result of the release of stress between the Nazca Plate and the South American Plate, on the Peru–Chile Trench. The focus was relatively shallow at 33 km, considering that earthquakes
2010 earthquake, but is considered to be an aftershock of the earlier quake. At 5.09 p.m. on Sunday 21 July 2013 a magnitude 6.5 earthquake rocked central New Zealand, causing minor damage. The earthquake was centred in Cook Strait, about 20 kilometres east of Seddon in Marlborough. In Wellington city goods fell from supermarket shelves and plate glass and masonry fell from downtown buildings. Four people were hospitalised with minor injuries but there were no fatalities.
