The diversity of location and place that is cause by earth surface distribution which are widely spread and not the same between one place to another. There are three concepts that related onto it, to help you understand it, we need to know about these three, which are pattern, location diversity, and regionalization.
1. Pattern
Natural phenomena are not spread evenly on the surface of the earth form a variety of patterns are depicted on maps in various scales. For example: the world’s climate patterns, the pattern of spread of the mountain-fire, river drainage patterns, patterns of human occupation (farming, farming, trade, industry), settlement patterns, traffic patterns, etc. Read the rest of this entry »
Instead of emissions from human activities in the fields of energy, forestry, agriculture and animal husbandry, human waste or trash is also a major contributor to global climate change.
Humans in any activity always produces waste that contributes greatly to greenhouse gas emissions (GHG) emissions. Scientific facts show that the waste is one contributor to greenhouse gases in the form of methane (CH4) and carbon dioxide (CO2).

Ocean have been dominating earth, almost 70% of earth covered by water. This large amount of waters are believed comes from eruption of volcano around four billion years ago.
The geology of the sea floor was largely unknown until the last half of the twentieth century, when the rapid advance of new technologies allowed geologists to study the sea floor in great detail.

Both plate boundaries and plates move over time. As previously described, plates can change the locations of trenches and subduction zones, as well as the positions of midoceanic ridges and transform faults . For example, subduction at a convergent boundary can stop in one location and begin nearby in another. Plates can become larger or smaller over time depending on the generation rates of new crust at spreading centers and the rates of subduction.
Convection currents. Some geologists favor convection currents in the mantle as the best explanation for plate tectonic movement. It is reasonable to assume that the heat radiated from the core creates convection currents in the mantle, and the mantle rocks begin to move plastically.

The internal temperature of the earth increases with depth from the surface. Near the surface, the average geothermal gradient is about 25 degrees centigrade (77 degrees Fahrenheit) for every kilometer of depth. Some areas have much higher heat flows because of deep fault zones, rifting, magmatic intrusions, or active tectonic forces. The geothermal gradient can make conditions in deep mines quite uncomfortable and hot enough to explode rocks or bend steel.
The geothermal gradient of 25 degrees centigrade/kilometer is thought to be restricted to the upper part of the crust . If it continued at this rate uniformly from the surface, the internal temperature of the earth would be greater than 2,000 degrees centigrade within the lithosphere a temperature that far exceeds the melting temperatures for all rocks at that depth.
