Themes;Subfields
In geography, density refers to the number of a particular feature (such as population or buildings) within a defined area, often expressed as a ratio or percentage. It helps geographers understand the distribution and concentration of various phenomena across different regions.
Different types of livelihood in different places can include farming, fishing, herding, hunting, forestry, mining, manufacturing, service industries, and tourism. The type of livelihood often depends on factors such as natural resources, climate, geography, and cultural traditions specific to each region.
Geographers gather information through a variety of methods such as conducting fieldwork, using satellite imagery and remote sensing, analyzing geographic information systems (GIS), collecting and analyzing census data, utilizing surveys and interviews, and studying historical documents and maps. They often combine multiple methods to generate a comprehensive understanding of geographical phenomena.
Geography is considered both a science and an art. As a science, it involves the study of the Earth's physical features and processes. As an art, it involves the interpretation and representation of spatial data, often using maps and visualizations.
Geography and climate impact where people live by dictating available resources, such as water and arable land, as well as natural hazards like hurricanes or earthquakes. These factors influence settlement patterns, with people often choosing to live in areas with more favorable conditions. Additionally, climate can determine aspects of daily life, such as type of housing, clothing, and economic activities.
themes and subfield
Geographers often divide the Earth's complexity into various regions and themes, such as physical geography, human geography, and environmental geography. This segmentation allows for a more focused analysis of specific aspects like landforms, climate, population dynamics, and cultural landscapes. By employing tools like Geographic Information Systems (GIS) and spatial analysis, geographers can visualize patterns and relationships, enhancing our understanding of the intricate interactions between humans and their environment. Through this structured approach, we can better address global challenges such as urbanization, climate change, and resource management.
Eratosthenes, a Greek polymath who lived from 276 to 194 BCE, is often credited with being the "father of geography." He made significant contributions by calculating the Earth's circumference with remarkable accuracy using measurements of the angles of shadows in different locations. His work laid the foundational principles of geography as a scientific discipline and introduced concepts of latitude and longitude. Eratosthenes' approach combined mathematics, astronomy, and geography, influencing future generations of geographers and scholars.
The founder of modern human geography is often considered to be Carl Ritter, a German geographer of the 19th century. He, along with Alexander von Humboldt, helped establish geography as a scientific discipline by emphasizing the relationship between humans and their environment. Ritter's work laid the groundwork for systematic geography, influencing later geographers and shaping the study of human geography.
geography is often described as an interdisciplinary field of study since it consists of many fields such as physical geography and human geography.Under physical geography and human geography,there are other subfields such as climatology and geomorphology for physical geography and cultural and population geography which are under human geography.
In geography, density refers to the number of a particular feature (such as population or buildings) within a defined area, often expressed as a ratio or percentage. It helps geographers understand the distribution and concentration of various phenomena across different regions.
Geographers (those who study weather/land/people) usually do not often need to use a coordinate grid. However those studying geometry (a branch of maths) do use them.
Geography as a discipline can be split into two fields, Human Geography and Physical Geography. The first relates to how space is created, viewed and managed and the second relates to how climate, vegatation, life, soil, water and landforms are produced and interact. A subfield has emerged known as Environmental geography which combines human and physical geography
hemispheres. (:
Environmental geography is a branch of geography that studies the interaction between human societies and their natural environment. It examines how human activities impact the environment, such as through deforestation, urbanization, and pollution, and seeks to understand the relationships between people and their surroundings. Environmental geographers often work to develop sustainable solutions to environmental challenges.
Geographers often utilize historical geography to understand how places have changed over time. This study examines the historical processes that shape landscapes, communities, and regions, analyzing spatial patterns and transformations through various periods. By integrating archival research, cartographic analysis, and field studies, historians and geographers can trace the evolution of places, revealing the interplay of social, economic, and environmental factors that contribute to change.
Geography is dependent of other fields for data. Soil relates to agriculture, physiography relates to geology, the subject of people relates to economics or sociology, political geography relates to history, mathematical geography relates to astronomy, climatology relates to meteorology, and bio-geography relates to biology.
