Following are the four dimensions of geographical study or simply geography,
1- Regional Revolution: This is the part in which there are discussions upon, how the world regional geography works, the description of the areas, how international trends work about in the world, what differentiation exists among various regions.
These are the spatial dimensions which include mapping, movement and transportation, what is the distribution of areas, and spatial patterns, what are the boundaries along with what population is located where. This all is recorded through computerized systems.
3-Environmental determinism: This takes a look at how human beings impact nature and the world and vice versa. This study looks at natural disasters, environmentalism, the environmental perception, etc.
It looks at the effects and how humanity has the potential to transform the environment

Geography as an integrated discipline because Geography is all about nature and environment. It covers whole physical areas in the planet, and holistic nature.
Geography connects people with nature or environment. People can know about general knowledges from Geography. It connects people with the world. Earth, sky, lands you can know anything about world from Geography.

According to Wegener, all the continents formed a single continental mass, a mega ocean surrounded by the same. The super-continent was named Pangaea, which meant all earth.
Pangaea or Pangea was a supercontinent that existed during the late Paleozoic and early Mesozoic eras. It assembled from earlier continental units approximately 335 million years ago, and it began to break apart about 175 million years ago.In contrast to the present Earth and its distribution of continental mass, much of Pangaea was in the southern hemisphere and surrounded by a superocean, Panthalassa. Pangaea was the most recent supercontinent to have existed and the first to be reconstructed by geologists.

Body waves are the waves that can travel through the layers of the earth. They are the fastest waves and as a result, the first waves that seismographs can record. Body waves can move through all states of matter including rocks and molten lava.

Body waves travel through the interior of the Earth. On the other hand, surface waves propagate only at the interface between two different media, like the interface between Earth and atmosphere (i.e. the surface of the Earth).

Differentiation can be defined as a derivative of a function regarding the independent variable and can be applied to measure the function per unit change in the independent variable.
Let y = f(x) be a function of x. Then, the rate of change of “y” per unit change in “x” is given by dy / dx

Ecological balance is a state of dynamic equilibrium within a community of organisms in a habitat or ecosystem. It can happen when the diversity of living organisms remains relatively stable. Gradual changes do take place but that happens only through natural succession. It can also be explained as a stable balance in the numbers of each species in an ecosystem. This occurs through competition and cooperation between different organism s where the population remains stable. This balance is brought about by the fact that certain species compete with one another determined by the environment in which they grow. This balance is also attained by the fact that some species depend on others for their food and sustenance. Such accounts are encountered in vast grasslands where the herbivorous animals (deer, zebras, buffaloes, etc.) are found in plenty.
Ecological balance may be disturbed due to the introduction of new species, natural hazards or human causes. Human interference has affected the balance of plant communities leading to disturbances in the ecosystems. Such disturbances bring about numerous secondary successions. Human pressure on the earth’s resources has put a heavy toll on the ecosystem. This has destroyed its originality and has caused adverse effects to the general environment. Ecological imbalances have brought many natural calamities like floods, landslides, diseases, erratic climatic occurrences, etc. There is a very close relationship between the plant and animal communities within particular habitats. Diversity of life in a particular area can be employed as an indicator of the habitat factor. Proper knowledge and understanding of such factors provide a strong base for protecting and conserving the ecosystems.

Mineral: naturally occuring inorganic substance having an orderly atomic structure and a definite chemical composition and physical properties.
It is composed of two or three minerals /single element ex. S,Cu, Ag,Au, Graphite.
There are at least 2000 minerals in the crust. There are at least six mineral groups which form rocks in the crust.
The basic source of all minerals is the hot magma in the interior of the earth. Coal, petroleum and natural gas are organic minerals

The time of a place depends on the longitude that passes through it. Therefore, the standard time for each country is usually taken as the time of the central meridian that passes through it. India has a vast longitudinal extent. Since many meridians pass through it, it is important to adopt the local time of one central meridian of a country as the standard time for the country. Thus, we need a standard meridian for the country. In India 82 ½ °E longitude determines the standard time. This is known as the Indian Standard Time. This longitude passes through Allahabad in Uttar Pradesh.

Physical geography includes the study of lithosphere (landforms, drainage, relief and physiography), atmosphere (its composition,structure, elements and controls of weather and climate; temperature, pressure, winds,precipitation, climatic types, etc.),hydrosphere(oceans, seas, lakes and associated features with water realm) and biosphere ( life forms including human being and macro-organism and their sustaining mechanism, viz. food chain, ecological parameters and ecological balance).
The study of physical geography is emerging as a discipline of evaluating and managing natural resources. In order to achieve this objective, it is essential to understand the intricate relationship between physical environment and human beings. Physical environment provides resources, and human beings utilise these resources and ensure their economic and cultural development. Accelerated pace of resource utilisation with the help of modern technology has created ecological imbalance in the world. Hence, a better understanding of physical environment is absolutely essential for sustainable development.
