5. Analyze: Plates A, B, and C all lie in the northern hemisphere, the half of Earth north of the equator. Plates E, F, and G all lie in the southern hemisphere,

The north pole on the globe map is still located at 90°N and 0°W, but it is simply a single dot on the map since the globe is a sphere.

There are three main sections to this module: terrestrial coordinates, celestial equatorial coordinates, and understanding how the ecliptic is related to seasons on the Earth. Each of these sections has its own simulator(s). The background material necessary to utilize these tools is contained in each section.

There is no single conventional way in which the world is divided. Different Geographers focus on different parts of the world, while others cannot seem to agree where some regions start and end. “For one author the ‘Middle East’ stretches all the way from Morocco to Afghanistan; for another, it begins only at the Nile Valle; for a third, it might dip southward to encompass, sub-Saharan Somalia.” There are no definite natural separations between continents and it would therefore it would be contradictory to insist on consistent regional separations.

The earth has been through a lot of changes throughout time. It used to be thought that the continents were locked in their positions and couldn’t move, but in 1915 Alfred Wagner came up with a theory about continental drift (Tarbuck and Lutgens, 2015). While unsure of the process that happened at the time, Wagner also came up with the idea that all the continents in existence today were once all connected as one giant continent known as Pangea. This idea is supported by the findings of similar rocks or fossils in multiple locations separated by large water bodies. Thanks to more tools and funding, the oceanic ridge system was found and by 1968, the theory of plate tectonics was introduced (Tarbuck and Lutgens, 2015). This theory

Nearly everything that a human does is in response to the environment. Our lives are defined by what is around us and what we find in front of us, whether this means accepting, dealing with or changing it. This has been the pattern since primates first stood up and became Homo erectus, and has continued until we considered ourselves doubly wise. The shape of the land affected where humans moved. Weather was something with which to contend. Fire affected humans until they conquered it – and herein lies the core of the relationship. The earth affects humans, and humans affect it back, viewing characteristics and patterns as problems and challenges, and finding a solution.

The origins and axes of these coordinate systems are different. While the geocentric coordinate system has its origin at the centre of the mass of the earth and the regional (local) coordinates system has its centre different from the geocentre. These coordinate systems are associated with the term ‘datum’, which uses coordinates referred to the surface of defined ellipsoid of revolution. (Featherstone and Reit, 1998).
