Direction: Read the case Study given below and answer an three of the questions that follow.
The temperature-depth profile for the ocean water shows how the temperature decreases with the increasing depth. The profile shows a boundary region between the surface waters of the ocean and the deeper layers. The boundary usually begins around 100 - 400 m below the sea surface and extends several hundred of metres downward. This boundary region, from where there is a rapid decrease of temperature, is called the thermocline. About 90 per cent of the total volume of water is found below the thermocline in the deep ocean. In this zone, temperatures approach 0°C. The temperature structure of oceans over middle and low latitudes can be described as a three-layer system from surface to the bottom. The first layer represents the top layer of warm oceanic water and it is about 500 m thick with temperatures ranging between 20° and 25°C. This layer, within the tropical region, is present throughout the year but in mid latitudes it develops only during summer. The second layer called the thermocline layer lies below the first layer and is characterised by rapid decrease in temperature with increasing depth. The thermocline is 500-1,000 m thick. The third layer is very cold and extends upto the deep ocean floor. In the Arctic and Antarctic circles, the surface water temperatures are close to 0°C and so the temperature change with the depth is very slight. Here, only one layer of cold water exists, which extends from surface to deep ocean floor.

Understanding Ocean Temperatures in Polar Regions
The temperature of ocean waters in the Arctic and Antarctic circles is notably low due to their geographical locations and climatic conditions.
Key Points on Water Temperature
- Close to 0°C:
- The surface water temperatures in these polar regions hover around 0°C. This is primarily because the regions experience extremely cold air temperatures, which significantly cool the ocean surface.
- Uniform Temperature Layer:
- Unlike other regions, where distinct layers of warm and cold water exist, the Arctic and Antarctic circles typically have a single layer of cold water that extends from the surface to the ocean floor. This results in minimal temperature variation with increasing depth.
- Impact of Ice and Climate:
- The presence of sea ice limits the warming effect of solar radiation. During summer months, even when the sun is shining, the temperatures do not rise significantly above freezing due to the insulating properties of ice.
- Ecological Implications:
- The cold temperatures influence marine life and ecosystems, affecting species distribution and the overall biodiversity of these regions.
In conclusion, the water temperatures in the Arctic and Antarctic circles are indeed close to 0°C, which is a crucial aspect of their environmental characteristics and marine ecosystems.

Direction: Read the case study given below and answer any three of the questions that follow.Different places on the earth’s surface receive different amounts of rainfall in a year and that too in different seasons. In general, as we proceed from the Equator towards the Poles, rainfall goes on decreasing steadily. The coastal areas of the world receive greater amounts of rainfall than the interior of the continents. The rainfall is more over the oceans than on the land masses of the world because of being great sources of water. Between the latitudes 350 and 400 N and S of the Equator, the rain is heavier on the eastern coasts and goes on decreasing towards the West. But, between 450 and 650 N and S of Equator, due to the westerlies, the rainfall is first received on the western margins of the continents and it goes on decreasing towards the East. Wherever mountains run parallel to the coast, the rain is greater on the coastal plain, on the windward side and it decreases towards the leeward side. On the basis of the total amount of annual precipitation, major precipitation regimes of the world are identified as follows: The equatorial belt, the windward slopes of the mountains along the western coasts in the cool temperate zone and the coastal areas of the monsoon land receive heavy rainfall of over 200 cm per annum. Interior continental areas receive moderate rainfall varying from 100 - 200 cm per annum. The coastal areas of the continents receive moderate amount of rainfall. The central parts of the tropical land and the eastern and interior parts of the temperate lands receive rainfall varying between 50 – 100 cm per annum. Areas lying in the rain shadow zone of the interior of the continents and high latitudes receive very low rainfall-less than 50 cm per annum. Seasonal distribution of rainfall provides an important aspect to judge its effectiveness. In some regions rainfall is distributed evenly throughout the year such as in the equatorial belt and in the western parts of cool temperate regions.Q. In general, as we proceed from the equator towards the poles, rainfall goes on ______ steadily.

Direction: Read the case study given below and answer any three of the questions that follow.The temperature of the world is significantly increasing. Carbon dioxide produced by human activities is a major source of concern. This gas, released to the atmosphere in large quantities by burning of fossil fuel, is increasing gradually. Other gases like methane, chlorofluorocarbons, and nitrous oxide which are present in much smaller concentrations in the atmosphere, together with carbon dioxide are known as greenhouse gases. These gases are better absorbers of long wave radiations than carbon dioxide, and so, are more effective at enhancing the greenhouse effect. These gases have been contributing to global warming. It is said that due to global warming the polar ice caps and mountain glaciers would melt and the amount of water in the oceans would increase. The mean annual surface temperature of the earth in the past 150 years has increased. It is projected that by the year 2,100, global temperature will increase by about 2°C. This rise in temperature will cause many other changes: one of these is arise in sea level, as a result of melting of glaciers and sea-ice due to warming. According to the current prediction, on an average, the sea level will rise 48 cm by the end of twenty first century. This would increase the incidence of annual flooding. Climatic change would promote insect-borne diseases like malaria, and lead to shift in climatic boundaries, making some regions wetter and others drier. Agricultural pattern would shift and human population as well as the ecosystem would experience change.Q. Methane, chlorofluorocarbons and nitrous oxide along with carbon dioxide is known as
