Burton described 'quantitative revolution' as a radical transformation of the spirit and purpose of Geography. The quantitative revolution was a paradigm shift that sought to develop a more rigorous and systematic methodology for the discipline of geography. It came as a response to the inadequacy of regional geography to explain general spatial dynamics. In the 1950s and 1960s, a revolutionary change described as "quantitative revolution" occurred in the discipline of geography.
It replaced the 'idiographic' approach based on areal differentiation by ‘nomothetic' one, which had its roots in the search for models of spatial structure and phenomenon.

Whenever we talk about the definition of Sampling, it can be said that it is a technique where the sampler selects some of the elements with the intention of finding out a conclusion about the total population from which they are taken.
Sampling can be categorized into two, Probability sampling Non-probability sampling Stratified sampling: In reference of stratified sample, in this methodology, researchers divide a population into homogeneous subpopulations called strata (the plural of stratum) based on specific characteristics (e.g., race, gender, location, etc.).
Every member of the population should be in exactly one stratum.
Each stratum is then sampled using another probability sampling method, such as cluster or simple random sampling, allowing researchers to estimate statistical measures for each sub-population.

Ratzel propounded the 'Organic Theory of State' in his book Politshe Geographie in 1897. "Organic Theory" comes from Ratzel's assertion that political entities, such as countries, behave in a way not too dissimilar from that of living organisms. A nation requires nourishment in the form of gaining land to survive in the same way that a living organism seeks nourishment from food to survive.

Two cycle theory regarding the 'origin of Limestone caves' was propounded by W.M Davis in his paper 'Origin of limestone caverns published' in 1930. According to this theory limestone caves are formed by the action of water below the water table instead of above. Two cycle theory states that action of water on ground happens in two stages. In the first cycle, water play dissolving processes and in the second cycle water table decrease. This leads to draining of surrounding area.

The Himalayas is divided into three ranges from north to south. They are the Lesser Himalayas, the Great Himalayas, and the Outer Himalayas. The correct sequence of mountain ranges in Jammu and Kashmir state is Laddakh, Zanskar, Pir Panjal, Shiwalik.

The average annual rainfall of whole India is 119 cm, but it has great spatial variations. Assam has Average annual rainfall of 2,818 mm.
Bihar has Average annual rainfall of 1256 mm.
Uttar Pradesh has Average annual rainfall of 1025 mm.
Haryana has Average annual rainfall of 617 mm.
Thus, the Correct answer is 2.

Corrosion is the chemical weathering of bed and bank materials in contact with the stream water. Significantly, Corrasion or abrasion is the wearing away of surfaces over which the water flows by the impact or grinding action of particles moving with the water body. Thus, the Correct answer is C.

Arctic snow covered areas does not have intermediate ecological productivity. Areas such as Grasslands, shallow lakes and farmlands have intermediate ecological productivity. A constant input of solar energy is the basic requirement for any ecosystem to function and sustain. Primary production is defined as the amount of biomass or organic matter produced per unit area over a time period by plants during photosynthesis.
Herbivores that feed on plants are called primary consumers. The consumers that feed on these herbivores are carnivores. Thus, the correct answer is B.
