Soil geography deals with the distribution of soils across the terrain. This discipline, between geography and soil science, is fundamental to both physical geography and pedology. [9] [10] [11] Pedology is the study of soils in their natural environment.
In all, the atmosphere is made up of about 78.0% nitrogen, 20.9% oxygen, and 0.92% argon, and small amounts of other gases including CO 2 and water vapor. [15] Water vapor and CO 2 cause the Earth's atmosphere to catch and hold the Sun's energy through the greenhouse effect . [ 16 ]
[1] [2] [3] A branch of natural science – natural science is a major branch of science that tries to explain and predict nature's phenomena, based on empirical evidence. In natural science, hypotheses must be verified scientifically to be regarded as scientific theory. Validity, accuracy, and social mechanisms ensuring quality control, such ...
Although a common classroom experiment is often explained this way, [441] Bernoulli's principle only applies within a flow field, and the air above and below the paper is in different flow fields. [442] The paper rises because the air follows the curve of the paper and a curved streamline will develop pressure differences perpendicular to the ...
Human geography – one of the two main subfields of geography is the study of human use and understanding of the world and the processes that have affected it. Human geography broadly differs from physical geography in that it focuses on the built environment and how space is created, viewed, and managed by humans, as well as the influence humans have on the space they occupy.
The five themes were published in 1984 [1] and widely adopted by teachers, textbook publishers, and curriculum designers in the United States. [2] Most American geography and social studies classrooms have adopted the five themes in teaching practices, [3] as they provide "an alternative to the detrimental, but unfortunately persistent, habit ...
[1] [2] [3] It aims to explain and predict the distribution and dynamics of human and physical geography through the collection and analysis of quantifiable data. [4] The approach quantitative geographers take is generally in line with the scientific method, where a falsifiable hypothesis is generated, and then tested through observational ...
Science is a systematic discipline that builds and organises knowledge in the form of testable hypotheses and predictions about the universe. [1] [2] Modern science is typically divided into two or three major branches: [3] the natural sciences (e.g., physics, chemistry, and biology), which study the physical world; and the social sciences (e.g., economics, psychology, and sociology), which ...
