Sunspots usually appear in pairs of opposite magnetic polarity with a leader and a follower. An IOD phenomenon can influence El Nino’s impact on the monsoon. Until roughly 140 million years ago, the Indian Plate formed part of the supercontinent Gondwana. At the northern end of the Great Rift Valley, and separated by live volcanoes from the Red Sea, the plain was formed by the evaporation of an inland water body.

In 2016, Arctic permafrost temperatures were 3.5 degrees Celsius higher than at the beginning of the 20th century.

From 1965 to 2017, the Bay of Bengal and the Arabian Sea collectively registered 46 ‘severe cyclonic storms’. Over 150 million years ago, enormous reptiles swam the Jurassic oceans. Sky watchers may see more auroras, and space agencies must monitor radiation storms for astronaut protection.

This was also the case in 2016, and 2024 will again be a leap year. On the contrary, the South magnetic pole drift is very slow (less than 10 km per year). The result builds on an informal vote taken at the 2016 International Geological Congress in Cape Town, and lays the groundwork for a formal proposal by 2021 to the International Commission on Stratigraphy. But it’s not! It marks the boundary between the Indian and Eurasian plates. The strawberry moon eclipse is going to be its second and probably the last visible lunar one in 2020. Eventually, the droplets grow large enough to fall to Earth. This year is a mild La Niña, according to the World Meteorological Organization. Mains level : Formation of our solar system. India does not have a DST, even though there are large parts of the country where winter days are shorter. Because of that, the salinity and pH/alkalinity levels have also come down and green algae have started growing in the water body. In this type of an eclipse, the moon does not block the sun completely, but looks like a “dark disk on top of a larger sun-colored disk” forming a “ring of fire”.

The World Meteorological Organization (WMO) is a specialized agency of the United Nations responsible for promoting international cooperation on atmospheric science, climatology, hydrology and geophysics.. This list contained names proposed by the eight member countries of WMO/ESCAP PTC, viz., Bangladesh, India, Maldives, Myanmar, Oman, Pakistan, Sri Lanka and Thailand. Individuals were expected to wake up an hour earlier than usual, and complete their daily work routines an hour earlier. In the Philippines, a volcano called Taal on the island of Luzon; 50 km from Manila has recently erupted. Global archaeological data show that human transformation of environments began at different times in different regions and accelerated with the emergence of agriculture. It is likely to generate winds of speed 110-120 km per hour. The Ring of Fire is a direct result of plate tectonics: the movement and collisions of lithospheric plates, especially subduction in the northern portion.

Another debate is whether the height should be based on the highest rock point or the highest snow point.

This mechanism is known as the solar dynamo mechanism (or magnetohydrodynamic dynamo mechanism). The strength of the magnetic field also constantly changes and currently it is showing signs of significant weakening.

This happens because air is a poor conductor of electricity, and electrons that are travelling through air seek both a better conductor and the shortest route to the relatively positively charged Earth’s surface.

When it was observed for the first time in 1964 by radio astronomers Arnold Penzias and Robert Wilson —who would go on to be awarded the 1978 Physics Nobel — they were initially puzzled. Any object that obstructs light will produce two shadows: one which will be dark and dense, is called the umbra; and the other which is light and diffused is called the penumbra.

There are three types of eclipses: one is a total solar eclipse, which is visible only from a small area on Earth.

This can be inferred by observing when the relative orientation of the sunspot pairs flips. Cyclone Fani in April-May and Cyclone Maha in October were of the ‘Extremely Severe’ category, with wind speeds greater than 200 km/hr.

When the landmass that is now the Indian subcontinent slammed into Asia about 50 million years ago, the oxygen in the world’s oceans increased, altering the conditions for life. A supermoon is all scheduled to show up in the sky on April 7. The new maps reveal Zealandia’s bathymetry (the shape of the ocean floor) as well as its tectonic history, showing how volcanism and tectonic motion have shaped the continent over millions of years. The third kind is an annular solar eclipse, which happens when the moon is farthest from the Earth, which is why it seems smaller. Power outages, satellite malfunctions, communication disruptions, and GPS receiver malfunctions are just a few of the things that can happen during a solar maximum.

For Prelims and Mains: WMO- objectives, functions, reports and significance. Arabian Sea cyclones are also relatively weak compared to those emerging in the Bay of Bengal.

Such anoxic ecosystems are considered a critical environmental and ecological issue as they have led to several mass extinctions. Researchers have attributed neotectonic activities to the Chambal ravines genesis. In the last 120 years for which records are available, just about 14% of all cyclonic storms, and 23% of severe cyclones, around India have occurred in the Arabian Sea.

A lunar eclipse can occur only on the night of a full moon. However, there have been times during Earth history when intense volcanism has significantly increased the amount of carbon dioxide in the atmosphere and caused global warming. Volcanoes also release large amounts of greenhouse gases such as water vapor and carbon dioxide. The slurry-like composition of the snow pack slows the seismic waves in such a way that the variation in snow pile size — thinner in the eastern hemisphere and thicker in the western — affected the speed of the waves.
