Earth's internal heat budget The reason for the existence of convergent boundaries are the mid-ocean ridges that were only beginning to be understood with the acceptance of the theory of plate tectonics in the mids. The radioactive decay of elements within the rocks in the interior of the earth generates large amounts of heat that moves magma to the surface of the crust in a process called mantle convection. This results in a new oceanic crust or sea floor being formed that slowly moves away from the ridges sometimes called spreading centers towards the subduction zones.
The Geography of Transport Systems Overview The mobility of people, freight and information is fundamental to economic and social activities such as commuting, manufacturing, distributing goods, or supplying energy.
Each movement has a purpose, an origin, a potential set of intermediate locations, and a destination. Transport systems are the support and driver of this mobility and are composed of infrastructures, modes and terminals, enabling individuals, institutions, corporations, regions and nations to interact and function.
Understanding how mobility is linked with geography is main the purpose of this textbook. What is transport geography?
Mainly aimed at an undergraduate audience, the Geography of Transport Systems offers a comprehensive and accessible introduction to the field with a broad overview of its concepts, methods and areas of application. It provides material about transportation issues to practitioners, policymakers, educators, researchers, students, and individual learners and includes a wide variety of media elements such as mapsfigures and PowerPoint presentations.
Organization The textbook is divided in twelve chapters. The first nine chapters cover a specific conceptual dimension of transport geography, such networks, modes, terminals and urban transportation. In addition to these conventional topics, emerging issues such as globalization, supply chain management, information technologies, energy and the environment are also thoroughly discussed.
Since transport is a field of application, the use of methodologies is particularly relevant to assist transport operators allocate their resources investments, infrastructure, vehicles or to influence public policy.
The tenth chapter focuses on qualitative and quantitative methodologies linked with transport geography such as accessibility, spatial interactions and graph theory. The convergence between methodologies and information technologies has led to many new analytical opportunities, notably with geographic information systems for transportation GIS-T.
Transportation is a very active field of investigation and application to real world issues, which are covered in the eleventh chapter. These include, among others, city logistics, cruise shipping, high speed rail, or the financing of transport infrastructure.

The theory of plate tectonics states that the Earth’s solid outer crust, the lithosphere, is separated into plates that move over the asthenosphere, the molten upper portion of the mantle. Oceanic and continental plates come together, spread apart, and interact at boundaries all over the planet.
In plate tectonics, a convergent boundary, also known as a destructive plate boundary, is a region of active deformation where two or more tectonic plates or fragments of the lithosphere are near the end of their life cycle.
This is in contrast to a constructive plate boundary (also known as a mid-ocean ridge or spreading center). As a result of pressure, friction, and plate material melting.
Plate tectonics: Plate tectonics, theory dealing with the dynamics of Earth’s outer shell that revolutionized Earth sciences by providing a uniform context for understanding mountain-building processes, volcanoes, and earthquakes as well as the evolution of Earth’s surface and reconstructing its past continents and oceans.
This mineral identification chart was created by Art Crossman as a college course project at Mansfield University in He did an outstanding job, organizing minerals on the chart in a systematic way - according to their properties. (40) Plate tectonics theory is the scientific theory that describes the large-scale motion of the Earth’s lithosphere, which is broken up into tectonic plates.
Volcanic landforms are undoubtedly very important in aiding our understanding of plate tectonic theory.
