Layers of rock wear off during which of the following processes?
Maru [420]

Answer:

Exfoliation

Step-by-step explanation:

Changes in temperature cause rock to expand (with heat) and contract (with cold). As this happens over and over again, the structure of the rock weakens. Over time, it crumbles.

Rocky desert landscapes are particularly vulnerable to thermal stress. The outer layer of desert rocks undergo repeated stress as the temperature changes from day to night. Eventually, outer layers flake off in thin sheets, a process called exfoliation.

In ∆abc, m∠cab = 2x and m∠​acb = x + 30. if line segment a b is extended through point b to point d, m∠​cbd = 5x − 50. what is t
Allisa [31]
The answer is option "3, 40".

<span>m∠cab = 2x
m∠​acb = x + 30
m∠​cbd = 5x − 50
Now,
</span>m∠cab + m∠​acb = m∠​cbd 
2x+x+30 = 5x-50
2x+x-5x = -50-30
-2x = -80
x = 40
