Correct Answer: Metamorphic
Correct Answer: centrifugation
Explanation:
Sometimes the solid particles in a liquid are very small and can pass through a filter paper. For such particles, the filtration technique cannot be used for separation. Such mixtures are separated by centrifugation.
Correct Answer: Wind gap
Explanation:
Demoiselles
These are rock pillars which stand as resistant rocks above soft rocks as a result of differential erosion of hard and soft rocks.
Zeugen
A table-shaped area of rock found in arid and semi-arid areas formed when more resistant rock is reduced at a slower rate than softer rocks around it.
A Dreikanter
It is a type of ventifact that typically forms in desert or periglacial environments due to the abrasive action of blowing sand.
A wind gap is a gap through which a waterway once flowed that is now dry as a result of stream capture.
Correct Answer: Syzygy conjunction occurs at the time of perihelion only.
Explanation:
In astronomy, a syzygy is a straight-line configuration of three or more celestial bodies in a gravitational system.Solar and lunar eclipses occur at times of syzygy, as do transits and occultations.
Correct Answer: 1, 2, 3 and 4
Explanation:
In troposphere and mesosphere, temperature declines with increasing altitude. In stratosphere and thermosphere, temperature increases with increasing altitude.The coldest temperatures in Earth?s atmosphere occur at the top of mesosphere, the Mesopause, especially in the summer near the pole.Transitional layers of atmosphere include tropopause, stratopause, and mesopause. These layers are relatively thin and are located between major layers of atmosphere. These have contrasting thermal properties. Hence, in these layers there is no change in temperature with change in altitude.
Correct Answer: Proxima Centauri
Explanation:
Proxima Centauri is the nearest star, and on August 24, 2016 astronomers announced it likely has a planet. This star is the nearest of a triple star system, which we on Earth see with the eye alone as the single star Alpha Centauri, visible from Earth's Southern Hemisphere
Correct Answer: Mercury
Explanation:
Correct Answer: Himachal Pradesh
Explanation:
Presently, there are 226 flood forecasting stations consisting of 166 level forecasting stations for villages and towns and 60 inflow forecasting stations for reservoirs/dams/barrages in the country. Existing flood forecasting network covers 22 States / Union Territories and 19 major river basins / sub-basins in the country.
Correct Answer: Thermosetting
Explanation:
Thermoset, or thermosetting, plastics are synthetic materials that strengthen during being heated, but cannot be successfully remouldedor reheated after their initial heat-forming. This contrasts withthermoplastics, which soften when heated and harden and strengthen after cooling. Thermoplastics can be heated, shaped and cooled as often as necessary without causing a chemical change, while thermosetting plastics will burn when heated after the initial moulding.
Correct Answer: Trapping of solar energy due to atmospheric gases
