<h3><u>
Answer:</u> </h3>
<u>The statements that best describe the minerals shown in the picture are as below:</u>
- The "mineral on the right" formed from magma.
- The "mineral on the left" has "larger crystals" than the mineral on the right.
- The mineral on the left "cooled more slowly" than the mineral on the right.
<h3><u>
Explanation:</u> </h3>
- Magma is nothing but unerupted lava. Thus, the mineral on the right can be said to have formed from magma.
- It is apparent that the mineral on the left has larger crystals than the mineral on the right.
- The size of the crystals in the mineral on the left proves that the mineral on the left got more time to cool down which resulted in the formation of larger crystals.

The Earth's ocean is a large body of water that is divided into four parts: Atlantic, Arctic, Indian, and Pacific Ocean. Some countries like the U.S. started recognizing the Southern Ocean as the fifth, though it's still not always considered one of the main ones. The answer is B: four.
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 +
