If the coordinates of point A are (x, y ) the coordinates of point A´ after rotation will be (-y, x)
Example: A ( 2,3 ) and A´( -3, 2 )
It's d it has to be because the Japan has to do something
Answer:
he larger the crystals and the more mafic the composition
Explanation:
Temperature at which minerals crystallize can determine the nature of composition of the rock and the crystal sizes.
- When a magma crystallizes at high temperature, the mineral grains have enough time to aggregate around a nuclei.
- This makes the sizes big.
- Mafic minerals are know to crystallize at high temperatures.
- Felsic minerals differentiate at low temperatures.
It would defiantly turn red, because of the atmosphere.
Answer: Red
Answer:
Sedimentary rocks are the rocks that are formed as a result of compaction and lithification of sediments. These are directly obtained from the sediments of the pre-existing rock. These sediments after weathering of the rocks are transported from one place to another with the help of agents such as wind, water, and ice. These sediments are then deposited at a different place. Then, it finally turns into sedimentary rocks. For example, Shale, Sandstone and Limestone.
The common minerals that are found to be present in the sedimentary rocks are feldspar, clay minerals, and mica. The sediments such as quartz and clay minerals are derived by chemical weathering of rocks that act as a cementing material holding the sediments together. These sedimentary rock-forming minerals are abundant on the earth's surface and are comparatively much stable. So, with time, they undergo compaction and solidification and forms sedimentary rocks.
