the great circle

 

the great circle

 Concept

The full circle that divides the earth into two equal parts is the great circle. A circle is called a great circle only when it has the following three characteristics - that is - the largest circle in the sphere. Larger circles cannot be drawn on the globe.

 The earth is divided into two equal parts along the arc and the center of the 3 globes and the center of the earth will always be at one point. So the radius of the great circle and the radius of the globe are always equal. These three features are the only equator among the numerous axes and longitudes drawn on the globe. So the equator is an example of a great circle.



 As the equatorial circumference is the largest, it is the largest circle in the globe. Other circles are small circles. All perpendicular axes except the equator are tiny circles. On the other hand, circles can be drawn on a geosphere extending through the north and south poles. Their centers are also located at the center of the globe. In fact, such circles point to two opposite longitudes. So the imaginary circle is also a great circle.

 In other words, two opposite longitudinal lines combine to form a great circle (such as 0 ° longitude and 1800 longitude lines or longitudinal lines one half semicircle. And through the middle part of the pole, innumerable circles can be drawn diagonally.

Definition 

1) Drawing a globe or imagining with the surface of the earth that the center point of the circular plane of the circle is located at the same point with the center of the globe or the earth is called a great circle.


2) That perfect circle divides the earth into two equal parts. He is called Mahabritta.


3) The equator that lies in the middle of the earth is called the great circle. The equator (0) is called the ellipse.


4) A circle that is imagined on the earth or drawn on the globe is located at the same point with the center of the earth or the globe.


5) The largest imaginary circle on the surface of the earth is the great circle.


Importance


The shortest distance between any two points on a globe is the arc of a circle that touches those two points. 


That is to say, the shortest path for the movement of aircraft and ships between any two places on the surface of the earth is determined by the help of the imaginary arc between those two places. If not, you have to cross a long distance. For this reason, sailors by sea and pilots by air travel along the path of the Great Circle. This saves time and money

SCOPE OF ECONOMIC GEOGRAPHY

  SCOPE OF ECONOMIC GEOGRAPHY Economic geography was defined by the German scholar Gotz in 1882 as "a scientific analysis of the character of world territories in their direct influence on goods."Despite the fact that Gotz was the one who coined the term "economic geography," his influence was limited to Germany. Because the abstract principles of the time were not developed, they could not be connected to economic geography. Economic geography owes its development as an academic topic to the British public's interest in business. It's worth noting that George Chisholm, the pioneer of contemporary economic geography, intended to instill a sense of intellectual curiosity in the study of geographic facts. He believed that economic geography's fundamental purpose is to "create some plausible forecast of the future course of commercial development insofar as that is affected by geographical conditions."Chisholm, on the other hand, focused on comme

Loxodrome or rhumb line or constant bearing line

  Q loxodrome or  Q rhumb line or  Q constant bearing line Definition 1 The line drawn to draw the distance between two l on the graticules drawn for drawing a map by axis and longitude is called rumb line or loxodome.V 2 When a straight line is drawn between two points on the globe, the origin of the angle is called rumb line or loxodrome. 3 A straight line drawn on the projection of the marketer intersects all the longitudes at a certain angle and is marked as a straight line pointing in a certain direction. It is called rumb line or loxodrome. 4 Since the longitudes of the marketer projection are parallel straight lines, any other straight line drawn on it intersects the longitudes at the same angle and creates angles equal to all the latitudes (at the points of intersection). This results in the formation of a constant bearing line over the globe. Such a line is called loxodrome or rumb line. Characteristih 1 No loxodro or rumb line is required when drawing all types of pr

Sandstone

Sandstone • Origin  Sandstone belongs to sedimentary rocks. Sandstone is the rock formed by the solidification of sand particles. • Features • Features  The sand particles in sandstone are usually quartz, the sand particles are mainly spherical. Quartz particles are small. Fine-grained sandstone with siltstone and pebble-like particles Sandstone is called conglomerate. This rock does not corrode easily when exposed to silicon or other similar elements, the sandstones are red and yellow in color depending on the material. Sand particles. Its color is red or brown when precipitated by silica, calcium carbonate or kaolin. Sandstone particles are harder than cementitious materials. Therefore, when they are broken, the solid particles are intact but the coagulant is broken. Sandstone composed of silica is very hard, so it is used in house construction. Ways of identification: 1 Composition— Quartz and some magnesium minerals. 2 Shapes—Lamination 3 colors - grayish yellow, reddish brown. 4 W

Possible modifiers of future livestock production and consumption trends

  Possible modifiers of future livestock production and consumption trends (a) Competition for resources (i) Land On the suitable land of the humid–sub humid zones, some rise in production is likely to occur where this is possiblethrough the use of improved pastures and effective management. In the more arid and semiarid areas, livestock are a key mechanism for managing risk.However increases of population are fragmenting rangelands in many places and making difficult for pastoralists to gain access to the feed and water resources that they have traditionally been able to access.In the future, grazing systems will increasingly provide ecosystem goods and services that are traded.But it is not clear, how future livestock production from these systems may be affected.  The mixed crop–livestock systems will continue to be critical to future food securitybecause two-thirds of the global population live in these systems. (ii) Water Globally freshwater resources are relatively scarce. Fre

DEFINITION OF ECONOMY GEOGRAPHY

  DEFINITION OF ECONOMY GEOGRAPHY The definition of economic geography has been given by different scholars in different ways. Definitions of some leading scholars and thinkers are presented here: According to Bangston and Von Royen “Economic Geography investigates the diversity in basic resources of the different parts of the world. It tries to evaluate the effect that differences in physical environment have upon the utilization of these resources. It studies differences in economic development in different regions of countries of the world. It also studies transportation, trade - routes and trade resulting from the differential development and as affected by the physical environment”. According to G. Chisholm “It (Economic Geography) embraces all geographical conditions affecting the production, transport and exchange of commodities.  Its chief use is to enable us to form some reasonable estimate of the future course of commercial development so far as that is governed” According t
