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 +
Answer:
B
Explanation:
A is incorrect because the Appalachians are not jagged and point
C is incorrect because erosion/deposition would do this
D is incorrect because weathering does not affect tectonic plates
They began to form by a combination of volcanic activity and the deposit of marine sediments. It formed along northwest Africa about 530 million years ago. ... As the Appalachian Mountains eroded, sand and clay were deposited over Florida's limestone layer.
Answer:
its me again got banned im the one who made this question
Explanation:
Meteorology is the study of the climate and weather
Clouds form when (invisible) water vapor turns into visible water droplets or ice, it then becomes gas.
The rain occurs because the clouds have water droplets in them, they condense into each other and then fall to earth as rain.
Thunder is created when lighting passes through the air.

A meteorologia é o estudo do clima e do tempo
Nuvens se formam quando o vapor de água (invisível) se transforma em gotículas de água visíveis ou gelo, então se transforma em gás.
A chuva ocorre porque as nuvens têm gotículas de água, elas se condensam umas nas outras e caem na terra como chuva.
O trovão é criado quando a luz passa pelo ar.
sorry i missed the last one :(
