Question

Differentiation of magma in a magma chamber results in a more felsic magma. a. True b. False The greater the percentage of silica in magma, the less viscous it is. a. True b. False The velocity of a river usually increases downstream. a. True b. False The discharge of a river usually decreases downstream. a. True b. False Quartz is easily weathered to clay. a. True b. False Synclines and Anticlines are formed due to: a. Compression b. Tension c. are formed by tension and Anticlines are formed by compression d. Synclines are formed compression and Anticlines are formed by tension

Explanation / Answer

32. Differentiation of magma in magma chamber results in a more felsic magma

true

33. the greater the percentage of silica in magma , a less viscous it is

false because viscosity of magma increases with the silica content

34.the velocity of river usually increase in downstream

false , because river slope decreases in downstream direction

35.the discharge of river usually decrease dowstream

false

36. quartz is easily weateherd to clay

false , quarrtz is resistant to weathering due to high hardness and lack of cleavage

37. syncline and anticline are formed due to

a. compression
