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.
Reflection and transmission of light waves occur because the frequencies of the light waves do not match the natural frequencies of vibration of the objects. When light waves of these frequencies strike an object, the electrons in the atoms of the object begin vibrating.
