Where is mechanical weathering most likely to occur?
– Weathering depends on water and temperature. – Mechanical weathering occurs fastest in areas that have a lot of temperature changes. – Chemical weathering is fastest where the climate is warm and wet, near the equator.
Which type of mechanical weathering is most common in mountainous regions?
Ice wedging is common in Earth’s polar regions and mid latitudes, and also at higher elevations, such as in the mountains. Abrasion is another form of mechanical weathering. In abrasion, one rock bumps against another rock.
What causes mechanical weathering?
Ice wedging, pressure release, plant root growth, and abrasion can all cause mechanical weathering. in the cracks and pores of rocks, the force of its expansion is strong enough to split the rocks apart. … This release of pressure causes the rock to expand. As the rock expands, cracks form in it, leading to exfoliation.
How does mechanical weathering take place in the weathering process of rocks?
Mechanical weathering, also called physical weathering, breaks rock into smaller pieces. These smaller pieces are just like the bigger rock, just smaller. That means the rock has changed physically without changing its composition.
