Context: Scientists from China recently discovered a space hurricane for the first time ever above the North pole. Previously, it was believed, space hurricanes were a theoretical phenomenon.
What are space hurricanes?
- They are thought to be a result of the solar wind and Earth’s magnetic field interacting.
- It is a huge, funnel-like, spiral geomagnetic storm that occurs above the polar Ionosphere of Earth, during extremely quiet conditions.
- They are related to the aurora borealis phenomenon, as the electron precipitation from the storm’s funnel produces gigantic, cyclone-shaped auroras.
- They are made up of plasmas, consisting of extremely hot ionized gases that rotate at extremely high speeds. As per their report, the hurricane measured roughly 600 miles across and rained down charged electrons for as long as eight hours.
- The space hurricane spun counterclockwise at speeds up to 4,700 miles per hour, the academic paper reported.
Scientists believe that they occur in the polar regions of planets with magnetic fields. Hurricanes have also been spotted in the lower atmospheres of our neighboring planets of Mars, Jupiter, and Saturn, while similar phenomena – so-called “solar tornados” – have even been spotted churning the surface of the Sun. However, such swirling masses had never before been detected in the upper atmosphere of a planet.

Abraham accord refers to the establishment of full diplomatic ties between UAE and Bahrain with Israel under a deal brokered by the United States.
- UAE and Israel have agreed to establish full diplomatic ties as part of a deal to halt the annexation of occupied land sought by the Palestinians for their future state.
- It makes UAE the first Gulf Arab state to do so and the third Arab nation after Egypt and Jordan to have active diplomatic ties to Israel.
1978 – Camp David agreement
Israel and Egypt agree on a framework for regional peace that called for an Israeli withdrawal in stages from Egypt’s Sinai and a transitional Palestinian government in the West Bank and Gaza.
1993-1995 – Oslo Accords
Israel and the PLO hold secret talks in Norway that resulted in interim peace accords calling for the establishment of Palestinian interim self-government and an elected council in the West Bank and Gaza for a five-year transitional period, Israeli troop withdrawals, and negotiations on a permanent settlement.

ARAB COUNTRIES
- Arab countries are a group of 22 countries that are members of the Arab League.
- Arabic is used as the lingua franca throughout the Arab world.
- However all Arabic-speaking nations are not part of the Arab world.
- Malta, an island country in Southern Europe whose national language also derives from Arabic (through Sicilian Arabic), is not included in the region. It was formed in Cairo in 1945 initially with six members: Egypt, Iraq, Jordan, Lebanon, Saudi Arabia, and Syria. Six countries have observer states—Eritrea, Brazil, and Venezuela, India, Armenia, and Chad.
- In a response to the United Arab Emirates and Bahrain normalizing their ties with Israel, the Palestinian Authority has formally stepped down from a key role in the Arab League.

The Saudi-led coalition of four Arab countries (the United Arab Emirates, Bahrain, and Egypt) had recently announced the restoration of ties with Qatar. In 2017, Saudi Arabia led an Arab transport blockade against Qatar, in order to punish Doha for its ties with radical Islamist groups.
Gulf cooperation council
The Gulf Cooperation Council (GCC) was established by an agreement concluded on 25 May 1981 in Riyadh,
Saudi Arabia among Bahrain, Kuwait, Oman, Qatar, Saudi Arabia, and UAE in view of their special relations, geographic proximity, similar political systems based on Islamic beliefs, joint destiny, and common objectives.

Context: The Philippine military has ordered the deployment of more navy ships to the South China Sea amid a growing diplomatic row over a fleet of Chinese boats parked near a disputed reef- Reed Bank.
About the South China Sea dispute: It is a dispute over territory and sovereignty over ocean areas, and the Paracels and the Spratlys – two island chains claimed in whole or in part by a number of countries. Alongside the fully-fledged islands, there are dozens of rocky outcrops, atolls, sandbanks, and reefs, such as the Scarborough Shoal.

The Cool Temperate Western Margin (British Type) Climate:
The cool temperate western margins are under the permanent influence of the Westerlies all around the year. They are also regions of much cyclonic activity, typical of Britain, and are hence named British type of climate.
- Spatial spread: Britain, lowlands North-West Europe, northern and western France, Belgium, the Netherlands, Denmark, western Norway, and also north-western Iberia. In the southern hemisphere, southern Chile, Tasmania, and most parts of New Zealand.
- Temperature: The mean annual temperatures are usually between 5°C and 15°C. The annual range of temperature is small. Summers are, in fact, never very warm.
- Precipitation: The British type of climate has adequate rainfall throughout the year with a tendency towards a slight winter or autumn maximum from cyclonic sources since the rain-bearing winds come from the west, the western margins have the heaviest rainfall. The amount decreases eastwards with increasing distance from the sea.
- Natural Vegetation: The natural vegetation of this climatic type is deciduous forest. The trees shed their leaves in the cold season, for protecting themselves against the winter snow and frost. The common species include oak, elm, ash, birch, beech, poplar, and hornbeam.

The distinguishing features of the other three types of climate
- Mediterranean Type: It is a warm temperate western-margin climate. It rains here in the winter, and the summers are dry and warm.
- Steppe Type: It is a temperate continental type of climate with little rainfall and the natural vegetation is grass (varying in density and quality).
- Natal Type: This is experienced in the warm temperate eastern margin (non-monsoonal areas) of the southern hemisphere.

The islands of the Arabian sea include Lakshadweep and Minicoy. The entire group of islands is broadly divided by the Eleventh-degree channel, north of which is the Amini Island and to the south of the Cannanore Island.
- These are scattered between 8°N-12°N and 71°E -74°E longitude.
- These islands are located at a distance of 280 km-480 km off the Kerala coast.
- The entire island group is built of coral deposits.
- The entire group of islands is broadly divided by the Eleven-degree channel, north of which is the Amini Island, and to the south of the Cannanore Island.
- The Islands of this archipelago have storm beaches consisting of unconsolidated pebbles,
shingles, cobbles, and boulders on the eastern seaboard. The maritime boundary between the Maldives and India (Lakshadweep) runs through the Eight- degree channel, locally known as Addigiri Kandu. Saddle Peak or Saddle Hill is located on North Andaman Island in India’s Andaman and the Nicobar Islands. Narcondam is a small volcanic island located in the Andaman Sea. They are supposed to be dormant volcanoes.

There are three types of plate boundaries:
- Convergent Boundaries: Where the crust is destroyed as one plate dived under another. The location where the sinking of a plate occurs is called a subduction zone. There are three ways in which convergence can occur. These are: (i) between an oceanic and continental plate; (ii) between two oceanic plates; and (iii) between two continental plates.
- Divergent Boundaries: Where a new crust is generated as the plates pull away from each other. The sites where the plates move away from each other are called spreading sites. The best-known example of divergent boundaries is the Mid-Atlantic Ridge. At this, the American Plate(s) is/are separated from the Eurasian and African Plates.
- Transform Boundaries: Where the crust is neither produced nor destroyed as the plates slide horizontally past each other. Transform faults are the planes of separation generally perpendicular to the midoceanic ridges. As the eruptions do not take all along the entire crest at the same time, there is a differential movement of a portion of the plate away from the axis of the earth. Also, the rotation of the earth has its effect on the separated blocks of the plate portions
