b. S-wave---> P -wave-4 L-wave

c. L-wave-3 P-wave->S-wave

d. S-wave-->P-wave—>L-wave-->T-wave

C. The following is an example of a ______________dominated delta.

a. Tide

b. Stream

c. Wave

TRUE or FALSE

D. Silicates are, after carbonates, the second most abundant minerals in the crust of the Earth.

E. Quartz is a three dimensional arrangement of silica tetrahedra, while biotite is a chain-like arrangement.

F. A mineral's color and streak are always a consistent and reliable property for identification.

Explanation / Answer

A. a.Mass wasting includes the creeps, slides, flowsand falls. This is larger amounts of soil will be moved at a time in mass wasting and this need bigger movements. Falls, land slide, creeps will have that type of intensity.

B. a. P waves will be the first one to reach and then slowly comes the S waves and then the L waves as they have very less frequency.

C. That is a wave dominated delta because when we see the mouth bars they are reworked towards the direction of the shore which are parallel sand and beach.

D. False because silicates are most abundant when compared to the carbonates on the crust.

E. False Biotite comes when the silica tetrahedra are arranged in the form of sheets not in chains

F. True, Color and streak are the two properties in which you can identify a mineral
