The Harappa’s system of standardized weights and measures signified advance technology and an advancing civilization in the Indus River Valley. Remarkable accuracy in systems and tools of the Harappan people were demonstrated by fire-baked bricks which were consistently moisture resistant and uniformly sized.

Explanation:
From the magma silicate crystals are formed successively when the magma temperature reaches the typical melting temperature for each type of crystal. The first crystals formed at high temperatures can then change their composition or dissolve again. In this way the crystals already formed contribute their ions, molecules and atoms to magma and combine again forming new crystals whose melting temperature is lower than that of the first crystals formed. The new crystals are said to be stable at the lowest temperatures set now. These processes of change are called reactions. As several successive reactions occur as the magma temperature decreases the ordered series of reactions is called the BOWEN series in honor of the Canadian scientist who formulated this concept. There are two types of reactions, the continuous reaction and the discontinuous reaction.
<u>
By continuous reaction a crystal formed at high temperatures such as a plagioclase rich in the Ca2 +</u> component gradually varies its composition by replacing a portion of the Ca2 + ions with the Na + ions and a portion of the Al3 + ions with the Si4 + ions. To maintain its neutrality, the replacement of Ca2 + by Na + is coupled with the replacement of Al3 + by Si4 +. The series of continuous reaction starts from the plagioclase rich in Ca2 +, passes through several plagioclase of intermediate composition towards the plagioclase rich in Na +
Answer:
the answer is (c) the US Census Bureau
Answer:
B) 12 hours of daylight.
Explanation:
B) 12 hours of daylight.
In near the equator we experience 12 hours of daylight as the equator is situated exactly the halfway in between the two poles. The North pole experiences long daylight in the months, when the North Pole is tilted towards the Sun and shorter daylight when the pole tilted away from the Sun. The reverse is true for the Southern Poles. But this wouldn't have any effects in daylight on the equator.
