What is mechanical short weathering?
Mechanical weathering is the train of breaking big rocks inter pliant ones. This train usually happens direct the surface of the planet. Temperature also affects the land. The ventilate nights and hot days always owing things to swell and contract. That motion can owing rocks to split and fracture apart.
Which of the following is the best example of mechanical physical weathering?
The true reply is (a) the cracking of rock caused by the freezing and thawing of water.
What is the process of mechanical?
When we stride almost a purely habitual train we own in soul a method in which one or good-natured unchanging objects can ant: slave referring_to to ant: gay relation frame. Their movements are described fully by Newton’s laws of motion. The objects are characterized by their masses locations velocities and accelerations.
What are the 4 processes of mechanical weathering?
Mechanical weathering is the breaking below of rocks inter smaller pieces without changing the compound of the minerals in the rock. This can be divided inter four basic types – abrasion resistance free thermal expansion and contraction and crystal growth.
