Assess the strength of the relationship between tectonic processes and major landforms on the earth’s surface. Tectonic processes have been responsible for the major landforms across the Earth’s surface. These processes are controlled by the convection currents rising from the Earth’s mantle. Firstly‚ one place where tectonic activity occurs is at oceanic to oceanic constructive plate boundaries. Here two plates diverge or move away from each other‚ pushed apart by huge convection currents

Additionally to the accommodation the groups could book different tours for an extra payment. The climate in Ural Mountains: In January‚ the coldest month of the year‚ average temperature is -17 °C. July is the warmest month of the year. The average temperature is 18 °C. The hottest temperatures are 35-38 °C Depending on the season and the locality as well as the

1. Compare the age of igneous rock found near the mid-ocean ridge with that of igneous rock found farther away from the ridge. The ages of the igneous rock found near the mid-ocean ridge was younger than the igneous rock found farther away from the ridge. This is because of convection currents. Magma rises because it is less dense. It is forced out of the ridge‚ it spreads apart‚ and when it cools‚ it becomes new seafloor. This is why newer seafloor (igneous rock) is younger when it is closer to

Earth: Earth’s tectonic plates (or plates which float separately and independently of the hotter mantle which sits below them) are categorized into three major categories‚ these being: Primary (Major)‚ Secondary (Minor) and Tertiary (or‚ micro-plates.) The seven major (or‚ any plates which range over at least 10 million kilometers) plates are: African plate‚ Antarctic plate‚ Eurasian plate‚ Indo-Australian plate‚ North American plate‚ Pacific plate and South American plate. These are also the

Evaluate how plate tectonics theory helps our understanding of the distribution of seismic and volcanic events(40) The global seismic and volcanic activity is concentrated along the margins of the earth’s plates‚ which are broken pieces of the crust and are moved by convection currents that are caused by heat rising and falling inside the mantle generated by radioactive decay in the core. This movement of the plates and the Earth’s inner activity is called plate tectonics and can cause seismic and

In the early 1960s‚ the emergence of the theory of plate tectonics started a revolution in the earth sciences. Since then‚ scientists have verified and refined this theory‚ and now have a much better understanding of how our planet has been shaped by plate-tectonic processes. We now know that‚ directly or indirectly‚ plate tectonics influences nearly all geologic processes‚ past and present. Indeed‚ the notion that the entire Earth’s surface is continually shifting has profoundly changed the way

Continental Drift and Plate Tectonics Theory (Part 1a) Introduction: The Beginning of the “Continental Drift Theory” In the middle of the eighteenth century‚ James Hutton proposed a theory‚ uniformitarianism; “the present is the key to the past”. It held that processes such as geologic forces- gradual and catastrophic-occurring in the present were the same that operated in the past. (Matt Rosenberg‚ 2004) This theory coincides with the theory of Continental Drift that was first proposed by Abraham

Evaluate how plate tectonics theory helps our understanding of the distribution of seismic and volcanic events. Plate tectonics is a relatively new science. It’s partially explained in the sense that we still don’t know fully about how the plates came together‚ what they were before they were the seven continents we know today. We already know‚ or have a theory‚ about what our world was like a long time ago and so if we already know that the plates can pull and push against each other‚ then surely

‘Evaluate how plate tectonics theory helps our understanding of the distribution of seismic and volcanic events’ In 1912‚ Alfred Wegener published his theory that a single super continent named Pangaea once existed about 300 million years ago. He proposed that Pangaea then later split into two continents of Laurasia in the north and Gondwanaland in the south and that today’s continents were the result of further splitting of these two land masses. Where the plates split are known as plate boundaries
