Answer 1

1. Answer is " d- all of the above" correct option

Because the endogenic process is such kind of that occurred within the earth except the surface of earth.

2. Answer is "volcanic activity"

Because it is a endogenic process and exogenic process is such process that occurs on the earth's surface.

3. Answer is "crust"

4.answer is "b-thinner and denser"

Because the oceanic crust contains mostly mafic minerals such olivine, plagioclase, pyroxene and amphibole etc that is why it denser.

5. Answer is "Oxygen"

Because the crust contains about 46.6wt%

Si -27.7wt%

Al-8.5wt%

Etc

6. Answer is "b- igneous"

These rocks are formed directly crystallized from the magma.

7.Answer is "b- mafic minerals"

Such as olivine, pyroxene, amphibole, plagioclase etc.

8. Answer is "a- light colored and silica rich"

Such as quartz, feldspar, plagioclase, mica

9. Answer is "intrusive"

10. Answer is " C-basalt"

11. Answer is " C-sedimentary rocks"

12. Abswer is " B- strata"

Because in stratigraphy, the rock layer is deoosited by the natural agencies such wind, water, and gleciers in the form of layer that layer is called as strata.

13. Answer is " C-batholiths"

The batholith is huge magma body that is crystallised below the surface of earth.

14. Anwer us " b- clastic"

Because other terms are used in igneous petrology.

15. Answer is " d- silt"

Because it is smallest perticle in all of the above thta are given in the question and its size about 1/64 to 1/256 mm.

16. Aanswer is " e-all of the above'

17. Answer is "d- all of the above"

Because the metamorphism is process by which change occured in texture and mineralogy of a rock such sedimentary, igneous, and also metamophic rocks as a result of temperature, pressure, and chemical active fluids, below the weathering zone.

18. Answer is "c- limestone".

Because the limestone undergone metamorphosed that produced the limestone.

19. Answer is " a- deep below the surface of earth"

20. Answer is " b- schist"

It is metamorphic rock which is formed by regional metamophism of shale such as grade

Shale- slate- phyllite- schist- gneiss- melts.
