Elements of Practical Geography

A Systematic Approach presents the topics essential for a clear understanding of human and physical Geography. The techniques of cartography, survey, mathematics and statistics are covered lucidly in this book. Geography is the study of Earth, its lands, features, and inhabitants. Just about every subject, from science to sports, has its own language. Geography has its own language too. In order to understand a subject, you need to understand the terms used by that subject. Geography has many different terms. Latitude and longitude are two such terms. Latitudes are imaginary lines that circle the earth and are parallel to the equator. The equator is the zero degree latitude line. Lines of latitude are measured my degrees. Human beings evolved under conditions of high mortality due to famines, accidents, illnesses, infections and war and therefore the relatively high fertility rates were essential for species survival. In spite of the relatively high fertility rates it took all the time from evolution of mankind to the middle of the 19th century for the global population to reach one billion. This book provides deep insight to various dimensions of issues relating to the subject.
