Physical geography focuses on natural processes of the earth, including climate and plate tectonics, whereas human geography studies the effect and behavior of humans and how they relate to the physical world. The two fields of geography are interrelated.Know More
Physical geography is concerned with the lithosphere, atmosphere, hydrosphere and biosphere. The lithosphere is made up of landforms near or at the surface of the earth comprised of solid and disintegrated rock and the soil cover on the surface. The hydrosphere is the section containing water in all its three states, while the atmosphere is the sphere of air around the earth.
Human geography investigates aspects of people’s way of life, such as language, religion, economic activity, government and art. The field also looks into globalization as a process by means of which cultural aspects transmit across the globe.
Geography relates behavior of man to his physical environment. This is important because physical geographical features determine the kind of activity people living around them can practice. For example, the natural environment in urban areas confines people living there to lifestyles different from those of rural dwellers. Conversely, human activities have a bearing on the physical environment. For instance, industrial carbon emissions are tied to climate change.Learn more about Maps & Cartography
Flat maps of the world look distorted when compared to a globe due to the difficulties of representing three-dimensional objects in two dimensions. Map projections are different ways of representing the various continents, but each provides its own distortion depending on the technique it uses.Full Answer >
According to NationalGeographic.com, bays are formed through various ways, such as plate tectonics, overflowing of the ocean to a coastline and the slicing of a glacier through a bedrock. Bays are bodies of water partially surrounded by land, and they are typically less enclosed and smaller than a gulf.Full Answer >
According to About.com, the Earth creates mountains through plate tectonics, where its crust is broken into plates constantly in motion, causing stress and uplifting in order to grow mountains. While growth is slow due to these forces, it does happen.Full Answer >
Andrew Alden of About explains that Australian geologist Sam Carey's theory of Earth expansion, the idea that the continents fit together properly only on a formerly smaller Earth, once rivaled the theory of plate tectonics. Carey's ideas expanded upon Wegener's continental-drift theory and hypothesised that the continents fit together properly on a shrunken Earth. From about the 1930s to the 1950s, this idea of Earth expansion remained a legitimate hypothesis.Full Answer >
