Answer:

The correct answer is D. 4,2,3,1

Explanation:

Shale is metamorphosed into three rock types( phyllite, schist and gneissic) a dull slate with cleavage, a rock with small mica crystals with a shiny aspect, a very shiny rock with large mica crystals and a banded gneissic rock.

Shales that are subject to heat and pressure of metamorphism alter into a hard, fissile, metamorphic rock known as slate. When metamorphic grade is continually increased the sequence is phyllite, then schist and finally gneiss.

Explain how a country can lessen its mortality rate.
Deffense [45]

Answer:

A feature of the reduction in death rates has been the increased excess mortality of males. There have also been big and rapid reductions in death rates in many developing countries, even in the absence of important improvements in living standards. Antibiotics and insecticides have made a major contribution to this movement in the last twenty years. It is unlikely that death rates will fall as rapidly in the next few decades as in the recent past in either developed or developing countries.

earnstyle [38]

Answer:

D. Because there was more gas farther from the Sun. As the are out of the range

Explanation:

  • Basically, due to the core acceleration mechanism, theory to the formation of gaseous objects that can pull the gas as farther away from the sun the impact of solar winds is quite less. There are low-pressure regions
  • Unlike rocky planets that have a different atmosphere and gas giants don't have a well-defined surface there atmosphere simply becomes denser to the core which may also be in a liquid-like state thus not suitable for landing.
  • There are four gaseous giants in our solar system such as Uranus, Neptune, Jupiter Saturn all have atmosphere covered with ice or gases and all are bigger as compared to terrestrial planets like earth thus they are called as Jovian planets.  
  • These Jovians attract large amounts of gas as their magnetic fields are stronger and huge size ad gas giants are known as metallic molecules of hydrogen and helium in core consisting of more than 50% of the planet masses.
