Which is an example of mechanical weathering quizlet?
An example of mechanical weathering is when the intense temperature of a forest fire causes nearby rocks to expand and crack. Sand and clay are both the result of mechanical weathering. If you pour water on sand, some of the water sticks to the surface.
Which is the best example of mechanical weathering?
Examples of mechanical weathering include frost and salt wedging, unloading and exfoliation, water and wind abrasion, impacts and collisions, and biological actions. All of these processes break rocks into smaller pieces without changing the physical composition of the rock.
Which is an example of mechanical weathering Brainly?
Answer: Examples of mechanical weathering include frost and salt wedging, unloading and exfoliation, water and wind abrasion, impacts and collisions, and biological actions. All of these processes break rocks into smaller pieces without changing the physical composition of the rock.
What is mechanical weathering quizlet?
Mechanical weathering is the physical breakdown of rock into smaller pieces. Chemical weathering is the breakdown of rock by chemical processes. … Ice can also cause mechanical weathering when water gets in cracks in rocks, and then freezes and expands. This widens the cracks, causing mechanical weathering.
Is ice wedging mechanical weathering?
Ice is one agent of mechanical weathering. Cycles of freezing and thawing can cause ice wedging, which can break rock into pieces. The cycle of ice wedging starts when water seeps into cracks in a rock. When the water freezes, it expands.
What are 5 mechanical weathering agents?
Agents of mechanical weathering include ice, wind, water, gravity, plants, and even, yes, animals [us]!
What are 5 types of mechanical weathering?
The 5 types of mechanical weathering include thermal expansion, frost weathering (or ice wedging), exfoliation, abrasion, and salt crystal growth.
