Air may be another factor in moving masses of earth material down steep

slopes. Confined by falling rock debris, air may act as a cushion to reduce the

friction between the sliding material and the underlying rock or ground.

Types of Landslides. Landslides and related phenomena are typically

classified according to the types of material transported and the way in which it

moves. Rockslides involve movements of newly detached blocks of bedrock

along tilted, water-lubricated joints, cracks, or bedding surfaces. Rockslides are

frequent in folded mountain ranges such as the Alps, Appalachians, and

Canadian Rockies. Mudflows are large flowing masses of rock, soil, and water of

mudlike consistency. They may occur in arid or semiarid mountainous regions

where they course down steep-walled gulches or canyons. Conditions conducive

to mudflows include loose, weathered surface rock; steep, barren hillslopes; and

heavy rain. Because they can carry huge quantities of debris—even houses and

automobiles—mudflows do millions of dollars in damage annually. Suburban

communities in hilly parts of Southern California are especially subject to such

disasters. Unlike mudflows, which are confined to channels, earthflows contain

221

less water and thus flow more slowly; they also move shorter distances

downslope than mudflows.

    空氣也許是其它因素在地球材料下來陡峭的傾斜移動的大量。由下落的岩石殘骸限制, 空氣也許作為坐墊減少摩擦在滑的材料和部下的岩石或地面之間。類型山崩。山崩和相關現象典型地被分類根據它行動材料被運輸和方式的型。崩落的岩石介入根底最近被分開的塊的運動沿被掀動的, 水被潤滑的聯接、鎮壓, 或臥具表面。崩落的岩石是頻繁在被摺疊的山脈譬如阿爾卑斯、阿巴拉契亞人, 和加拿大羅基斯。泥流是岩石、mudlike 一貫性土壤, 和水大流動的大量。他們也許發生在他們追獵在陡峭被圍住的gulches 或峽谷下的乾旱或半乾旱的多山地區。情況有助於泥流包括得寬鬆, 被風化的表面岩石; 陡峭, 貧瘠hillslopes; 並且大雨。由於他們能運載殘骸均勻房子和汽車泥流的巨大的數量年年做成千上萬美元在損傷。郊區社區在南加利福尼亞的多小山部份是特別是依於這樣災害。不同於泥流, 被限制對渠道, earthflows 包含221 較少水和慢慢地因而流動; 比起泥流他們並且移動更短的距離downslope 。
