South asia can be divided into three basic kinds: tropical, dry, and temperate. the Northeast East from tropical to subtropical temperature moving West to moisture and the elevation change causing a steppe and a desert climate that is like the Middle East.
Answer: 1) Angular separation equals 0.0000031 degrees
2) Angular separation in arc -seconds equals 0.011156"
Explanation:
For 2 stars separated by a distance 'S' and at a distance 'D' from the earth the angular separation in radians is given

Applying values we get

Now we know that 'π' radians equals 180 degrees thus the above value in degrees shall be equal to

2)
The angular separation in arc- seconds is given by

Answer: Clay and quartz
Explanation:Granite is a type of igneous rock that is present for injecting magma into the crust of Earth and then cools down. When weathering process occurs then there is breakage in the rocks at the Earth’s surface into other substances such as sediments, etc.
So, when there is the weathering in the granite the quartz will be same residual minerals because they have a resistance to weathering and biotite will have a hydrolysis process for the formation of clay.
