Geographic System, Part 1.

Geographic System, Part 2.

1. The study of the natural features of the Earth's surface: Geography comprises topography, climate, soil, vegetation, etc. and man's responses to them.
2. The physical features of a region, area, or place: Geography usually refers to surface features like rivers and mountains.
3. The science that deals with the description of land, sea, and air and the distribution of plant and animal life, including humans: Mr. Smart gave his students the assignment of reading about the geography of their region in their textbooks.
4. The scientific study of the Earth, including its composition, structure, physical properties, and history: Since Jack was very interested in geography, he decided to study it and learn all about the historical aspects and formation of the Earth.

Geology is commonly divided into subdisciplines concerned with the chemical makeup of the Earth, including:

• The study of minerals (mineralogy) and rocks (petrology).
• The structure of the Earth (structural geology) and volcanic phenomena (volcanology).
• Landforms and the processes that produce them (geomorphology and glaciology).
• The geologic history, including the study of fossils (paleontology).
• The development of sedimentary strata (stratigraphy).
• The evolution of planetary bodies and their satellites (astrogeology).
• Economic geology and its various branches; such as, mining geology and petroleum geology.
• Also, some major fields closely allied to geology are geodesy, geophysics, and geochemistry.

A major division of plant science which is concerned with all aspects of the spatial distribution of vegetation: Geographical botany, plant geography, and phytogeography all involve the study of the spatial distributions of plant life and of the environmental relationships which may influence these distributions.

Plant geography has emphasized the mapping of such regions and the interpretation of the terms of environmental (ecological) influences.

The areas of phytogeography and zoogeography do not necessarily exist together in the same place, because there are barriers and factors that affect their growth and arrangements which are often different for plants and for animals.

The study of energy development, transportation, markets: The students were asked to name the different kinds of energy and find out the use of energy patterns from a geographical perspective for their report on the geography of energy.

A branch of economics that deals with various production activities; such as, the influences that physical locations might have on factories.

In physical geography, the science dealing with the geographical distribution of various soil types: In his book about soil geography he was reading for class, Thomas found out that there were many different kinds of soils located in various parts of the world, or even in his own country.

A field of study which maps the growing regions of seedling organisms and analyzes them in terms of ecology, environmental, or ecological conditions: Mr. Younge, the professor of geography, was telling Kevin and the rest of his students about vegetational plant geography and how it differs in various areas of the world.
