Answer:
Agricultural production of food has caused two major problems. These are degradation of land and deforestation of land.
Explanation:
1. Degradation of Land:
The degradation of land in one form or the other is matter of serious concern endangering sustainability of agriculture. Landslides caused by rains and flowing water in hilly areas and deforestation, overgrazing and faulty cultural practices in the forest and other plain areas expose the soil to water and wind erosions. As may be seen from Table. 1, out of total geographical area, 141.3 million hectare (10.3 per cent) area is subject to such water and wind erosions.
2. Deforestation:
Increase in population resulting in more demand for fuel wood and timber, indiscriminate siting of development projects forest fires and forest area in the recent past has not changed much because its diversion for non-forestry purposes has been more or less compensated by afforestation.

superincumbent load in rock slab
Explanation:
- This pressure is defined as the geothermal pressure that the rocks excerpt from above the surface of the earth which is caused by the weighting of the overlying rock strata.
- This identification can be found in geology itself in terms of fluids and natural gases which led to the formation of coal deposits millions of years ago. With great pressure and thrust from the rocks
- This burning pressure that the rocks feel from above as in the case of earth core and mantle layers. A tectonic plate is subdued to greater depths here and this layer and hence more pressure from the remaining earth mass from above.
Answer: D. quaternary
Explanation: When we define all of the terms, it comes down to quaternary being the job sector that focus mainly on intellectual knowledge in order to take betters decisions. This matches the statement the best, so we can make a good judgement that D. quaternary is the answer.

Answer:
children and others living in slums
Explanation:
Even though India has one of the highest GDP's in the world, the real picture in the country in much different. The majority of the population lives in poverty and terrible conditions. This can be easily seen in the urban areas, where apart from small parts of them, the rest is slums. The slums offer no basic conditions for living, with water not being available or is of bad quality, the sewage non existent, houses not stable, hygiene is lacking, there's no healthcare... This is especially bad for the children, as they grow up in conditions in which they can easily catch a deadly disease, will probably end up uneducated, and will not have proper opportunities in life.
