Everything that exists, from the Galactic Mega clusters to the tiniest subatomic particles, comprises the Universe. According to the UN’s Food and Agriculture Organization (FAO), about 12% of the world’s population lives in the mountains, but over 50% are directly or indirectly dependent on mountain resources. The iron catastrophe allowed greater, more rapid movement of Earth’s molten, rocky material. Relatively buoyant material, such as silicates, water, and even air, stayed close to the planet’s exterior. Then suddenly with a bang, the Universe began to expand at an incredible rate and matter, energy, space and time came into being. Gravity then caused dust and gas to coalesce to the centre of the nebular cloud. Part of NCERT Geography notes for the UPSC exam. Question: JUNO Mission (UPSC Mains GS1-2017) Q5. Deccan Trap is a thick sequence of late cretaceous basaltic lava flows. : E.g. If verified, the new discovery suggests that planets may form 500,000 years earlier than previously thought within the overall lifespan of a star system. This wobble is measured using a precise spectrograph. Atmospheric Waves Experiment (AWE) mission| NASA | UPSC – IAS. At this instant, matter, energy, space and time were not existent. The NASA has selected a new mission Atmospheric Waves Experiment (AWE) and is expected to be launched in August 2022, attached to the exterior of the Earth-orbiting International Space Station.. Atmospheric waves are motions of air in the Earth’s atmosphere which have different spatial (meters to thousands of … Formation of Planets The following are regarded as the stages in the planets’ development: The stars are localised gas lumps inside a nebula. If there is a planet in between, the light of the star dims minutely. How does the Juno Mission of NASA help to understand the origin and evolution of the Earth? Star Formation! Evolution of Atmosphere! Our solar system consists of the sun, eight major planets, dwarf planets (Pluto, Ceres, Eris etc. The formation of planets The 0.1% of matter that remained orbited around the Sun, causing the randomly shaped gas cloud to form a flat disc shape.

In the inner, hotter part of the solar nebula, planetesimals were composed mostly of silicates and metals. Evolution of Hydrosphere! Another introducing Sun was passed near to our Sun, due to gravitation pull the cigar-shaped extension or bulge of material from our Sun was created. As the temperature reaches the dew point, the vapor starts condensing into small droplets forming clouds. Droplets of iron, nickel, and other heavy metals gravitated to the centre of Earth, becoming the early core. The four inner terrestrial planets Mercury, Venus, Earth, and Mars – are generally smaller, denser, and less oblate (more nearly spherical), and; They rotate more slowly on their axes than the four outer Jovian planets – Jupiter, Saturn, Uranus, and Neptune. Radioactive decay and leftover heat from planetary formation caused the ball to get even hotter.

Introduction. As the humidity present in it is in vapour form, it is called the dry adiabatic rate. At any rate, in simple terms, the clumping together of protoplanets (planets in formation) eventually formed the planets. This cycle lasts 11 years on average. • Planets were formed out of a slowly rotating cloud of gas and dust called a “NEBULA”. 2 Year Validity == Validity of the Download links (both Static & Current Affairs) is 2 Years from the date of purchase.
