It is shaped by a Mediterranean climate (mild, wet winters and hot dry summers) and wildfire, featuring summer-drought-tolerant plants with hard sclerophyllous evergreen leaves, as contrasted with the associated soft-leaved, drought-deciduous, scrub community of coastal sage scrub, found below the chaparral biome.n its natural state, chaparral is characterized by infrequent fires, with intervals ranging between 10â15 years to over a hundred years.
Echo is caused by reflection of the sound from a broad and hard obstacle. The echo can be heard if the following condition is met. To hear a distinct echo, the time interval between original sound and the reflection must be at least 0.1s.
People sometimes use vibration and frequency interchangeably but they both do have their differences. Vibration occurs when energy contracts toward the center point from which it first came out of. Oscillation happens when energy expands away from the center point. Frequency is achieved when one pattern or cycle of vibration and oscillation occurs. In other words, when an energy unit is done contracting and expanding, it has created one frequency pattern.
