All the above.
Explanation:
First statement is wrong because the magnetosphere stretches away from the Sun and nottowards the Sun.The solar wind is a stream of plasma released from the upper atmosphere of the Sun. Itconsists of mostly electrons, protons and alpha particles with energies usually between 1.5and 10 keV.As the solar wind approaches a planet that has a well-developed magnetic field (such asEarth, Jupiter and Saturn), the particles are deflected by the Lorentz force. This region,known as the magnetosphere, causes the particles to travel around the planet rather thanbombarding the atmosphere or surface. The magnetosphere is roughly shaped likea hemisphere on the side facing the Sun, then is drawn out in a long wake on the oppositeside. The boundary of this region is called the magnetopause, and some of the particles areable to penetrate the magnetosphere through this region by partial reconnection of themagnetic field lines.

Explanation:
Inter cropping disparity because it was food grains which got impetus especially wheat andmany other crops were neglected eg: pulses.Largely green revolution favoured large farmers than small and marginal farmers becausegreen revolution needed some initial investments for mechanization, high yielding seeds etcwhile small and marginal farmers could hardly afford such expenditures.With unbalanced fertilizers usage it led to soil fertility decline and also crops were grown insuch areas where those were not supposed to be grown like rice crop which was started inHaryana and Punjab because of Green revolution.Green revolution mainly benefitted North West India and coastal areas in Eastern India.Thus agricultural income increased only in those regions where Green revolution wasbrought and thus increasing regional disparity in terms of economy.Mechanization was supported and encouraged to get the better benefits of Greenrevolution thus resulting into unemployment. Self sufficiency was brought only in foodgrains like rice wheat etc, and not in every crop.

Which among the following is/are the not the push factors for rural to urban migration especially in India.
Unemployment.
Health and education facilities.
Monsoon vagaries.
Caste disabilities.
Explanation:
Human migration is the movement by people from one place to another with the intentionof settling temporarily or permanently in the new location. The movement is typically overlong distances and from one country to another, but internal migration is also possible.Migration may be individuals, family units or in large groups.There are 2 factors ie push and pull factor which might be real or perceptional.Push factors are those that force the individual to move voluntarily, and in many cases, theyare forced because the individual risk something if they stay.Pull factors are those factors in the destination region that attract the individual or group toleave their home. Those factors are known as place utility, which is the desirability of a placethat attracts people. Better economic opportunities, more jobs, and the promise of a betterlife like better health and education facilities often pull people into new locations.

1, 2 and 3
Explanation:
All these areas have Mediterranean type climate which is characterized by winter rains. As Chile is in southern hemisphere, it will have summer in the months of December-January and hence will have nil or very low rainfall.The other two areas located in northern hemisphere will have most of their annual rains in the winter months of December-January.

Explanation:
Pluto is the second largest dwarf planet next only to Eris. Venus and Uranus’ rotatorymotion is different from rest of the planets ie from East to West.Hydrogen nuclei combine to form helium inside the Sun under high temperature andpressure and releases huge heat energy and this process is nuclear fusion.

3751.Consider the statements regarding Earth’s interior and seismic waves.
1) Primary waves totally disappear in the core region revealing that outer core is made up of liquid.
2) Secondary waves show changes in its speed as it travels from magma chamber to lithosphere region indicating difference in density.
3) The speed of secondary waves is highest inside the Earth’s Core region indicating highest density in the Core region.
Choose the correct statement/s from the code below.

2 only.
1, 3only.
2, 3 only.
Explanation:
Primary waves (P-waves) are compressional waves that are longitudinal in nature. Thesewaves can travel through any type of material, including fluids, and can travel at nearlytwice the speed of S waves. Thus will not disappear in the core. But S waves do disappear inthe core region.Secondary waves (S-waves) are shear waves that are transverse in nature. S-waves cantravel only through solids, as fluids (liquids and gases) do not support shear stresses. Swavesare slower than P-waves, and speeds are typically around 60% of that of P-waves inany given material. S waves speed varies with density just like P waves and this speedincreases with increasing density. Since there is density difference between lithosphere andmagma chamber the speed of the S waves do change.S waves do not enter the Core region as the outer core is made up of liquid.

Explanation:
Sunspots are temporary phenomena on the photosphere of the Sun that appear visibly asdark spots compared to surrounding regions. They correspond to concentrationsof magnetic field that inhibit convection and result in reduced surface temperaturecompared to the surrounding photosphere. Sunspots usually appear as pairs, with each spothaving the opposite magnetic polarity of the other.Sunspot populations quickly rise and more slowly fall on an irregular cycle of 11 years,although significant variations in the number of sunspots attending the 11-year period areknown over longer spans of time.Since sunspots are darker than the surrounding photosphere it might be expected thatmore sunspots would lead to less solar radiation and a decreased solar constant. However,the surrounding margins of sunspots are brighter than the average, and so are hotter;overall, more sunspots increase the Suns solar constant or brightness.Thus sun spots do have effect on the Earth’s climate because it varies the solar radiationoutput thus affecting the insolation reaching on the Earth’s surface.

Explanation:
Close to 10 per cent of Indian households are opting to have only one child as they seek toconcentrate their resources to maximize earning opportunities for their offspring in ascramble for jobs. The trend is most pronounced among educated people in metropolitanareas, research by the Delhi-based National Council of Applied Economic Research shows.
