things expand when heated and contract when cooled. This seasaw action creates cracks and weakness in structures/landforms and causes weathering.
Convection
The temperature of that particular day
the earth goes through natural cycles of heating and cooling (ice-age and warming.) the thing is that natural cycles take centuries to millennium while the current warming phase is happening over decades- hence the name of global warming.

Physical weathering is caused by elements of nature. It is known as mechanical weathering to distinguish it from the other types of weathering namely chemical and biological. It occurs mechanically, by the breakdown due to natural components.
Subjection to extreme temperatures is an example of physical weathering, specifically known as thermal weathering. This process involves the expansion and contraction of materials due to repeated heating and cooling, which can lead to the breakdown of rocks and minerals.
Heating and cooling can contribute to mechanical weathering through a process called thermal expansion and contraction. When rocks heat up and expand, then cool down and contract, it can cause them to break apart due to the repeated stress.
This process is known as thermal stress weathering. It occurs when rocks expand and contract due to temperature changes, causing the outer layers to crack and break off. Over time, this repeated cycle of heating and cooling can lead to the disintegration and movement of rock layers.
In hot dry climates, physical weathering processes like thermal stress and insolation weathering are common. Thermal stress occurs when rocks expand and contract due to heating and cooling cycles, causing them to crack and break apart. Insolation weathering involves the repetitive heating and cooling of rock surfaces, leading to the expansion and contraction of minerals, which can result in peeling and flaking.
Weathering, erosion, deposition, compaction, and cementation.
because the rocks get very hot during the day with the sun, and then go very cold very rapidly at night time. this causes the rocks to expand and break away bits at a time, this is weathering of a rock.
Heating and cooling contribute to physical weathering by causing rocks to expand and contract, leading to cracks and fractures. This process, known as thermal expansion, weakens the rocks and makes them more susceptible to erosion from wind, water, and ice. Over time, this can break down rocks into smaller pieces.
Rocks can contract due to cooling and weathering processes. Cooling of molten rock can cause it to contract and solidify, while weathering processes such as frost wedging can lead to compaction and contraction of rock materials.
You have to manually select the heating, and cooling mode located on your thermostat.
Heating metal can cause it to expand, increasing its volume and potentially altering its shape and strength. Cooling metal can cause it to contract, reducing its volume and potentially making it more brittle. Rapid heating or cooling can also lead to thermal stress and distortions in the metal.
Subjection to extreme temperatures is an example of physical weathering, where rocks are broken down into smaller pieces due to repeated heating and cooling cycles. This process is known as thermal stress weathering.
Consultation of a licensed heating/cooling contractor is advisable when considering separating the heating and cooling units. The Guide to Heating and Air Conditioning is an excellent resource for information on heating/cooling repair work.
