Answer:
a. Transported water from distant mountains to flood the area
Explanation:
- Californian san Joaquin valley is a central valley of California that experiences a drought due to depletion of the groundwater and in 1920 it sunk up to 28 feet.
- As this region depends on large volumes of water this region is considered to be arid and semi-arid, the California state water project diverted surface water into the valley helped to prevent spring flood.

The fishermen who handle the waters of the Pacific off the shore of Peru and Ecuador have known for a considerable length of time about the El Niño. Each three to seven years amid the periods of December and January, angle in the waterfront waters off of these nations basically vanish, making the angling business grind to a halt. South American anglers have given this wonder the name El Niño, which is Spanish for "the Boy Child," since it happens the season of the festival of the introduction of the Christ Child. Amid an El Niño, the physical connections between wind, sea streams, maritime and environmental temperature, and biosphere separate into dangerous examples that are second just to the walk of the seasons in their effects to climate conditions the world over.
Educated people don't need to be in Iran. Iran doesn't provide colleges or any type of higher education that awards degrees. Iran is also a dangerous place, especially for women, seeing as you have gangs or terrorist groups such as The Taliban or Isis.
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 +
