Eurasian Plate

Eurasia has a horizontal axis, its land spread across similar latitudes. This made food production easier because the climates and seasons were similar. In conjunction with its geography, the Eurasian continent had the easiest time sharing and gathering techniques. Food production first formed in societies with access to clean, fresh water, river systems. Continents like Australia, first set back by geographical isolation, lacked these river systems and was therefore late to the game on food production. Other continents, the Americas and Africa, were spread with vertical axes and therefore varying climates and seasons across one continent. The ability of societies to exchange amongst each other was crucial. Continents that were vertical faced more struggles in trade than those that were horizontal. This diffusion within continents led to Crops were among the exchanges and helped advance individual societies engaged in these exchanges…

The status-caste exchange theory is to marry in terms of desirable traits; a desirable man marries a desirable woman based what she can provide in return (Hou & Myles, 2013). In regards to interracial marriage, the status-caste exchange theory assumes that the skin colour or ethnic origin as the desirable trait. Lighter skin colours are more desirable compared to darker skin colours, so the value of a partner is based on their skin colour or ethnic origin. If their socio-economic statuses were…

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…

of lives, while also saving billions in public taxpayer funds to rebuild after the damage. There are several types of gravitational forces that occur within the earth and 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.…

Mount Etna an active stratovolcano that towers 3,440 meters over the city of Catania on the Mediterranean Island of Sicily,Italy. It has been erupting for half a million years and the date of the last eruption was December 3, 2015. Mt. Etna was created on a boundary between the African and Eurasian plate. It was formed because the African plate subducted under the Eurasian plate. It has explosive types of eruptions from its 3 summit crater and the lava is pahoehoe. Mt. Etna has the longest…

are three groups of tetrapods. The lower jaw of mammals is composed of only one bone, compared to several bones in other tetrapods. Mammal’s upper and lower jaws hinge between a different set of bones in comparison to other tetrapods. The teeth in mammals are differentiated (incisors, canines, multi-pointed premolars and molars), unlike other tetrapods. Continental drift is defined as the process of movement in the mantle that cause the plates to move over time. According to the…

New crust is generated as plates pull away from each other and can either cause sea floor spreading or new land to be created. An example of a continental rift valley is the Eastern African Rift Valley which is being formed as the Eastern African plate is moving away from the main Africa plate in a north-easterly direction. Plates move apart due to convection currents in the lithosphere. As the crusts move away from each other the crust thins, tension in the lithosphere causes the plate to…

Tambora is plate tectonics. Islands in this chain along Indonesia are located along the convergent plate boundary of the Eurasian and Australian plates. A convergent boundary is the place where two tectonic plates collide. This can be oceanic-oceanic, oceanic-continental, or continental-continental. In the case of Mount Tambora, the Australian plate slides below the Eurasian plate. In this case a subduction zone is created. Here the sliding of the Australian plate under the Eurasian plate…

Japan is associated with so many natural disasters. This is because the island, Japan is located where the North American, Pacific, Eurasian, and Philippine plate meet, also known as plate boundaries. Japan is also located where the Pacific plate and the Philippine plate are subducting. This results in the stress building up where the two plates are subducting. How do plates move? Well, plates move when uneven heating in the mantle creates currents. This current is a convection current, and…

Key Question The key question for this research project is: what is the relationship of earthquakes and volcanoes along the Mid-Atlantic Ridge compared to Iceland? Introduction Iceland is located over the Mid-Atlantic Ridge between the North American Plate and the Eurasian Plate, and is an example of a mid ocean ridge seen on land. Iceland has divergent and transform plate boundaries, which are also seen along the Mid-Atlantic Ridge. The North American plate, with respect to the Eurasian…
