	C	1 and 3

	D	1, 2 and 3

Your Ans is

Right ans is C

Your Answer Is Correct

Your Answer Is Wrong

Explanation :

Context: The La Nina weather phenomenon is back in the central and eastern equatorial Pacific Ocean after nearly a decade’s absence, the World Meteorological Organization (WMO) said in its latest Global Seasonal update released on October 29, 2020.

El Nino-Southern Oscillation (ENSO)

El Nino and La Nina are opposite phases of what is known as the El Nino-Southern Oscillation (ENSO) cycle.
The ENSO cycle is a scientific term that describes the fluctuations in temperature between the ocean and atmosphere in the east-central Equatorial Pacific (approximately between the International Date Line and 120 degrees West).
La Nina is sometimes referred to as the cold phase of ENSO and El Nino as the warm phase of ENSO.
These deviations from normal surface temperatures can have large-scale impacts not only on ocean processes, but also on global weather and climate.
El Nino and La Nina episodes typically last nine to 12 months, but some prolonged events may last for years.
While their frequency can be quite irregular, El Nino and La Nina events occur on average every two to seven years.
Typically, El Nino occurs more frequently than La Nina.

El Nino

El Nino means ‘The Little Boy’, or ‘Christ Child’ in Spanish. El Nino was originally recognized by fishermen off the coast of South America in the 1600s, with the appearance of unusually warm water in the Pacific Ocean.
The name was chosen based on the time of year (around December) during which these warm waters events tended to occur.
It refers to the large-scale ocean-atmosphere climate interaction linked to a periodic warming in sea surface temperatures across the central and east-central Equatorial Pacific.
Typical El Nino effects are likely to develop over North America during the upcoming winter season.
Those include warmer-than-average temperatures over western and central Canada, and over the western and northern United States. Wetter-than-average conditions are likely over portions of the U.S. Gulf Coast and Florida, while drier-than-average conditions can be expected in the Ohio Valley and the Pacific Northwest.
The presence of El Nino can significantly influence weather patterns, ocean conditions, and marine fisheries across large portions of the globe for an extended period of time.

La Nina

La Nina means ‘The Little Girl’ in Spanish. La Nina is also sometimes called ‘El Viejo’, ‘anti-El Nino’, or simply ‘a cold event’.
La Nina episodes represent periods of below-average sea surface temperatures across the east-central Equatorial Pacific.
The effect of La Nina impacts on global climate tend to be opposite those of El Nino.
In the Tropics, ocean temperature variations in La Nina also tend to be opposite to those of El Nino.
During a La Nina year, winter temperatures are warmer than normal in the Southeast and cooler than normal in the Northwest.

Your Answer Is Correct

Your Answer Is Wrong

Explanation :

The 1982 United Nations Convention on the Law of the Sea (UNCLOS) defined the EEZ as a zone in the sea over which a sovereign nation has certain special rights with respect to the exploration and usage of marine resources, which includes the generation of energy from wind and water, and also oil and natural gas extraction.
The EEZ is an area that is adjacent to and beyond the territorial sea.It can extend to a maximum of 200 nautical miles from the baseline. The baseline is normally measured as the low-water line along the coast as indicated on large-scale charts officially approved by the coastal state.
The EEZ does not include the territorial sea and the continental shelf beyond 200 nautical miles.
The EEZ includes the contiguous zone.

Rights of a country in the EEZ

Explore and exploit, conserve and manage the natural resources (living or non-living).
Produce energy from wind, currents and water.
Establish and use artificial islands, structures and installations.
Conduct marine scientific research.
Protect and preserve the marine environment.

It aims to bring together all available bathymetric data to produce the definitive map of the world ocean floor by 2030 and make it available to all.
The project was launched at the United Nations (UN) Ocean Conference in June 2017 and is aligned with the UN's Sustainable Development Goal-14 to conserve and sustainably use the oceans, seas and marine resources.

Need

Despite many years of effort, less than 20 percent of the world ocean’s seafloor has been mapped.
A co-ordinated international effort is needed to bring together all existing data sets and to identify areas for future surveys - to help us 'map the gaps'.
Further, knowing the depth and shape of the seafloor (bathymetry) is fundamental for understanding ocean circulation, tides, tsunami forecasting, fishing resources, sediment transport, environmental change, underwater geo-hazards, cable and pipeline routing, mineral extraction, oil and gas exploration and development, infrastructure construction and maintenance and much more.

General Bathymetric Chart of the Oceans (GEBCO)

GEBCO is an international group of mapping experts developing a range of bathymetric data sets and data products.
It operates under the joint auspices of the International Hydrographic Organization (IHO) and UNESCO's Intergovernmental Oceanographic Commission (IOC).

	A	Switzerland and Italy

	B	Italy and France

	C	Switzerland and France

	D	France and Germany

Your Ans is

Right ans is A

Your Answer Is Correct

Your Answer Is Wrong

Explanation :

The Matterhorn is a mountain of the Alps, straddling the main watershed and border between Switzerland and Italy.
It is a large, near-symmetric pyramidal peak in the extended Monte Rosa area of the Pennine Alps, whose summit is 4,478 metres (14,692 ft) high, making it one of the highest summits in the Alps and Europe.
The four steep faces, rising above the surrounding glaciers, face the four compass points and are split by the Hörnli, Furggen, Leone/Lion, and Zmutt ridges.
Just east of the Matterhorn is Theodul Pass, the main passage between the two valleys on its north and south sides, and a trade route since the Roman Era.
The Matterhorn is mainly composed of gneisses (originally fragments of the African Plate before the Alpine orogeny) from the Dent Blanche nappe, lying over ophiolites and sedimentary rocks of the Penninic nappes.
The mountain's current shape is the result of cirque erosion due to multiple glaciers diverging from the peak, such as the Matterhorn Glacier at the base of the north face.
