Answer:
" Atmospheric instability is critical weather-maker "
Explanation:
- Instability is a condition where the earth's atmosphere is generally considered to be unstable as a result of the weather is subjected to a higher degree of variability over a larger distance and time.
- In metrology, instability is defined by the changes in temperature from the inversion layer in the form of a lapse rate. As the air gets unstable it has two forms as convective and dynamic instability.
- The dynamics are produced by horizontal motion and rest by the vertical motion. It is subject to Coriolis force and pressure gradient force. Thus dynamic lifting and mixing produced the cloud, precipitation, and storms.
- If the unstable atmosphere gets larger it leads to certain problems like dust veils when the winds are light and region of ground instability.
Answer:
Here is your answer
Explanation:
The centre of the earth is harder to study than the centre of the sun." Temperatures in the lower mantle the reach around 3,000-3,500 degrees Celsius and the barometer reads about 125 gigapascals, about one and a quarter million times atmospheric pressure.
Answer:
Geographic Information systems
Explanation:
Geographic information systems also known as GIS is used in collecting, storing, manipulating, analyzing geographic and spatial data.
GIS is core and very essential to making geographically oriented decisions. The system works more like a statistical set up but with a touch and edge of being able to handle geographic data perfectly well. This provides a new dimension for business, government etc to make decisions that would serve the need of all.
How it is used:
GIS is made up of different components which helps to make it very unique and special. The system consists of hardware, software and the people ware.
Attributes of features are collected with respect to a study. Their location are also included in the sampling. The software environment which can be a system application or web based one helps to manipulate the data in the best way to produce a fitting result.
To reach a level of accuracy in describing the earth in terms of the five themes of geography, people would have resorted to the following methods, mostly driven by observation:Location – geographic positioning would have been made through celestial navigation, or observing heavenly bodies (the Sun, Moon, fixed stars) and their relation to one’s location. Mapping would have been done by looking at the physical boundaries of one’s area.Place – observing the inhabitants of a place made people define the characteristics of that place. For example, racial characteristics of inhabitants, and physical characteristics of animal life that thrive in that area.Human and Environment Interactions – observing the seasons and climate of one’s geographical location, and how this affects people, primarily in the agricultural senseMovement – how humans move and interact with their environment establishes a description of the area. Observing how terrain affects the movement of a community (e.g., living in a sparse desert encourages inhabitants to be nomads, as opposed to living in a fertile valley which encourages farming.)Regions – the change in the terrain makes people define their environment. For example, volcanic eruptions can make people wary of the damage it can cause, but at the same time it makes people adapt to the change in land forms brought about by the eruption – for example, more fertile soil, changes in the flow of waterways, change in the availability of animal life for hunting or fishing.
