33. Snow, sleet and hail are the forms of

Correct Answer: (a) precipitation
Solution:Rain, Snow sleet or hails are the different forms of precipitation. Precipitation is any type of water that forms in the Earth's atmosphere and then drops onto the surface of the Earth. The rain that falls from clouds but freezes before it reaches the ground is called sleet or ice pellets. Snow is precipitation that falls in the form of ice crystals. Hail forms when very cold water droplets freeze, or turn solid, as soon as they touch things like dust or dirt. Water vapor in the atmosphere is visible as clouds and fog.

34. Which one of the following is likely to be the most prevalent form of weathering in hot-tropical desert areas?

Correct Answer: (a) Mechanical
Solution:The two main types of weathering which occur in deserts are Mechanical weathering, which is the disintegration of a rock by mechanical forces that do not change the rock's chemical composition and Chemical weathering, which is the decomposition of a rock by the alteration of its chemical composition. The arid or hot desert areas dominated by mechanical weathering. Due to the high diurnal range of temperature in the arid areas, repeated expansion and contraction of the outer layer of the rock takes place.

35. Which one of the following cities was the first to attain the status of a 'megacity'?

Correct Answer: (c) New York
Solution:New York City and Tokyo were the first known megacities, both reaching an urban conglomeration of over 10 million by the 1950s.

36. In India, rigid and stable elevated lands, denuded rocks and series of scarps are the features of which of the following?

Correct Answer: (b) Peninsular plateau
Solution:Peninsular Plateau consists of stable table land with highly dissected plateaus, denuded rocks and developed series of scarps.

37. A person has visited a region in India and found trees, such as Khair, Neem, Khejri and Palas. Which one of the following regions is she/he expected to have visited?

Correct Answer: (d) Desert Region
Solution:These occur in the areas which receive rainfall less than 50 cm and desert areas. It includes semi-arid areas of south west Punjab, Haryana, Rajasthan, Gujarat, Madhya Pradesh and Uttar Pradesh.
These consist of a variety of grasses and shrubs. In these forests, plants remain leafless for most part of the year and give an expression of scrub vegetation.Important species found are babool, ber and wild date palm, khair, neem, khejri, palas, etc. Tussocky grass upto a height of 2m as the under growth.

38. Consider the following statements:

1. Rocks do not remain in their original form for long and undergo transformation.
2. Transformation of rocks is caused by weathering, erosion and metamorphic action.
Which of the statements given above is/are correct?

Correct Answer: (c) Both 1 and 2
Solution:The three processes that change one rock to another are crystallization, metamorphism, and erosion and sedimentation. Any rock can transform into any other rock by passing through one or more of these processes. This creates the rock cycle. The rock cycle is a process in which rocks are continuously transformed between the three rock types igneous, sedimentary and metamorphic.

39. Weathering, mass wasting, erosion and transportation are indicators of which one of the following processes?

Correct Answer: (a) Denudation
Solution:In geology, denudation is the long-term sum of processes that cause the wearing away of the Earth's surface by moving water, ice, wind and waves, leading to a reduction in elevation and relief of landforms and landscapes. Denudation is the wearing away of landmass by various processes like weathering, mass movement, erosion and transportation.
It results in lowering the level of land, rounding exposed rock surfaces and levelling the peaks. Various agents of erosion like water, wind, and glaciers are involved in the process of denudation.

40. If you want to observe moraines, eskers and outwash plains, which one of the following Union Territories you may have to visit?

Correct Answer: (d) Ladakh
Solution:Moraines, eskers and outwash plains can be observed in the union territory of Ladakh. Outwash plains and eskers form due to the flow of meltwater in front of (outwash plains) or beneath (eskers) that glacier ice. They are composed of glacial sediments that have been reworked by flowing water.
The moraine lies about 3 km north of Leh at 3650 m altitude. The irrigated and relatively fertile outwash fan stands in sharp contrast to the adjacent alluvial fans and mountains ides that are devoid of most vegetation.
