Answer:
Option (C)
Explanation:
Migmatite can be defined as metamorphic rock that is formed at high pressure and temperature condition, depicting pro-grade type of metamorphism. This rock is formed from the partial melting of unaltered minerals or those minerals that are slightly modified. But in this process of formation, the bulk mass of the rock remains consistent. It is a transitional rock between the igneous and the metamorphic rock.
Thus, the correct answer is option (C).
When you put the continents next to each other (on a map, of course) in a certain way, they put together almost perfectly. To add to that, there are fossils of the same land species on two different continents, suggesting that they used to be able to cross back and forth between the two land masses. This would make the most sense if the two continents were once part of the same continent.
At the center of the solar nebula, the temperature would begin to rise because the nebula is contracting and therefore is increasing the motion of the atoms. The solar nebula is a proposed explanation of how the solar system was formed. It was believed it was from a collection of gas and dust called a nebula cloud.<span />
Answer:
The dark energy is one of the primary composition of the universe, which is not visible and are mysterious. as a very little is known about this energy. This dark energy makes up nearly 68% of the universe. It is often considered as a property of space. The presence of dark energy can be detected as it affects the expansion of the universe. The universe started to form right after the big bang explosion and since then the space is expanding in all direction. With this, the dark energy present in the universe also is expanding at a considerably faster rate in association with the Cosmic Microwave Background (CMB) radiation. The measurements of the distance and their connection with the redshift provided an evidence that the universe has been expanding at a certain speed.
