The main mechanism through which the layering happened is gravity: it pulled the heavier, denser material to the center, leaving the less dense material on the surface.
The material that was on the outside cooled quicker, but this was the result, not the cause.
The answer is
<span>2) Gravity caused more-dense material to move toward the center of each planet.</span>
Answer:
zenith distance = 39 degree
Explanation:
given data
declination of star = -13.00º
latitude = 26.00º N
to find out
distance in degrees between the star and zenith
solution
we know the formula that is
latitude = star declination+ its zenith distance ....................1
and
zenith distance = latitude - star declination
zenith distance = 26 - ( -13 )
zenith distance = 26 + 13
zenith distance = 39 degree
Answer:
d) Principle of Conservation of Matter
Explanation:
Principle of Conservation of Matter -
According to the law of conservation of matter, matter is the substance which ac not be created and even it can not be destroyed , hence we need to have the same number of atoms before and after the reaction constant during a chemical change or process of chemical as were number of atoms and type of atoms present before the chemical change .
Hence , from the options , the correct answer is the Principle of Conservation of Matter .
