The answer would be Atlantic plate have a very nice day
Answer:
C. plagioclase
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 +
Hello There! ^_^
Your question: Which one of the following times would be the longest..?
You answer: The Paleozoic Era would be the longest time span.
the answer is option B.
Hope this helps!
Claiming it as a historic item (which it is) through a document prevents common people to be affiliated with harming it. So by saying it is of significant history, citizens and tourists will not be able to do anything to jeopardize the natural landmark
Higher silica content means higher viscosity. But lower temperatures and low gas content mean higher viscosity. Hence, lower viscosity and low gas content mean higher temperature of magma.
