If you think that geography means memorizing a list of states and their capitals, think again. Geography is a broad and ever-changing subject. It includes the study of Earth's physical features, as well as the countless and fascinating ways that humans, animals, and plants interact with the world around them.
So if you want to learn more about water, climate and vegetation, you have to read a book Geography:The World and Its People ( Chapter 2) by Richard G Boehm; National Geographic Society (U.S.); Glencoe/McGraw-Hill.
Understanding that Earth is part of a larger physical system called the solar system helps us understand how life on our planet is possible. Earth’s physical systems —air, landforms, and water — are affected by natural forces such as earthquakes and volcanoes that can influence human activities on the planet.
