(c) Moon
(d) Alpha
Answer: b
Orion is a name of a ________.
(a) Star planet
(b) Planet
(c) Galaxy
(d) Constellation
Answer: d
The largest planet of the solar system:

(c) Jupiter
(d) Saturn
Answer: c
1) What is the point of origin of an earthquake?
(a) Epicenter
(b) Focus
(c) Foreshock
(d) Scarp
(e) Seismograph
Answer: (b)
The exact point where the earthquake actually starts deep inside the earth’s crust (the point of origin) is called the focus, or hypocenter.
2) What is the point on the surface nearest the earthquake?
(a) Epicenter
(b) Focus
(c) Foreshock
(d) Scarp
(e) Seismograph
Answer: (a)
The epicenter is the point on the earth’s surface vertically above the hypocenter (or focus), point in the crust where a seismic rupture begins
3) Places experiencing equal impact of an earthquake are called (CSS-2012)
(a) Snowlines
(b) seismic belts
(c) Seismic lines
(d) None of these
Answer: (c)
4) Where do most earthquakes occur?
(a) Along dikes
(b) Along faults
(c) Along folds
(d) Along joints
(e) Along unconformities
Answer: (b)
Earthquakes can also occur far from the edges of plates, along faults. Faults are cracks in the earth where sections of a plate (or two plates) are moving in different directions. Faults are caused by all that bumping and sliding the plates do. They are more common near the edges of the plates.
5) What is the standardized distance from an earthquake epicenter for measuring Richter magnitudes?
(a) 0 km
(b) 10 km
(c) 100 km
(d) 500 km
(e) 1000 km
Answer: (c)
Richter established 100 km as the standard distance from an earthquake epicenter to measure Richter magnitude with a Wood-Anderson seismograph.
Good Luck!

101) Which type of star is maintained by the pressure of an electron gas?
(a) Main Sequence Star
(b) White Dwarf
(c) Neutron Star
(d) Black Hole
Answer: (b)
White dwarfs are stars supported by pressure of degenerate electron gas. i.e. in their interiors thermal energy kT is much smaller then Fermi energy Ep. We shall derive the equations of structure of white dwarfs, sometimes called degenerate dwarfs, in the limiting case when their thermal pressure may be neglected, but the degenerate electron gas may be either non-relativistic. somewhat relativistic. or ultra-relativistic.
102) Which of the following first hypothesized that the Earth orbited the sun?
(a) Alexander the Great
(b) Copernicus
(c) Socrates
(d) Tycho Brahe
Answer: (b)
Nicolaus Copernicus was a Renaissance mathematician and astronomer who formulated a model of the universe that placed the Sun rather than the Earth at the center of the universe.
51) Planets are always small compared with stars because otherwise ______.
( a) the rotation of the planets would cause them to disintegrate
(b) the great mass of the planets would cause them to be pulled into their parent star
(c) the great mass of the planets would prevent them from being held in orbit and they would escape
(d) the planets would be stars themselves
Answer: (d)
52) The least likely reason why planetary systems have not been directly observed around stars other than the sun is that __
(a) Planets are small
(b) Planets shine by reflected light
(c) Planetary systems are rare
(d) Other stars are far away
Answer: (c)
53) Which of the following is the correct ordering of the inner planets according to their proximity to the sun? (CSS 2012)
(a) Jupiter, Saturn , Uranus , Neptune
(b) Phobos, Deimes , Europe , Tias
(c) Mercury, Venus, Earth, Mars
(d) None of these
Answer: (c)
Question: What were the main objectives of clean development mechanism? Also explain the reasons for the criticism on Koyoto Protocol by the developed countries. (General Science & Ability Paper CSS 2016)
The Clean Development Mechanism (CDM) is one of the Flexible Mechanisms defined in the Kyoto Protocol that provides for emissions reduction projects which generate Certified Emission Reduction units which may be traded in emissions trading schemes.
The Clean Development Mechanism is defined in Article 12 of the Protocol, and is intended to meet two objectives:

1) The biggest planet in our solar system is (CSS 2013)
(a) Venus
(b) Pluto
(c) Jupiter
(d) None of these
Answer: (c)
In terms of mass, volume, and surface area, Jupiter is the biggest planet in our Solar System by a wide margin.
Size and Mass:
Jupiter’s mass, volume, surface area and mean circumference are 1.8981 x 1027 kg, 1.43128 x 1015 km3, 6.1419 x 1010 km2, and 4.39264 x 105 km respectively. To put that in perspective, Jupiter diameter is roughly 11 times that of Earth, and 2.5 the mass of all the other planets in the Solar System combined.
2) The universe is ———-. (CSS 1996)
(a) Stationary
(b) Expanding
(c) Contracting
(d) None of these
Answer: (b)
In June 2016, NASA and ESA scientists reported that the universe was found to be expanding 5% to 9% faster than thought earlier, based on studies using the Hubble Space Telescope
