How might changes in temperature help form soil?
Changes in temperature can cause physical weathering of rocks through freeze-thaw cycles. During freezing, water in the cracks of rocks expands and exerts pressure, breaking the rocks into smaller pieces. Over time, these broken rocks mix with organic matter to form soil.
What are two causes of physical weathering?
Frost action: Water seeps into cracks in rocks, freezes, expands, and causes the rock to break apart. Temperature changes: Daily heating and cooling of rocks cause them to expand and contract, eventually leading to cracks and breakage.
How do sudden temperature changes cause weathering of rock?
Sudden temperature changes can cause thermal stress on rocks, leading to expansion and contraction. This repeated stress can cause the rocks to weaken and eventually break apart through a process known as thermal weathering. Additionally, frost wedging can occur when water enters cracks in the rock, freezes, and expands, further contributing to the weathering process.
What are 6 types of mechanical weathering?
Frost wedging: The repeated freezing and thawing of water in cracks in rocks. Salt crystal growth: Salt crystals form in the cracks of rocks and exert pressure as they expand. Exfoliation: Outer layers of rocks peel off due to pressure release. Thermal expansion and contraction: Rocks expand and contract due to changes in temperature, causing stress. Biological activity: Roots and burrowing animals can break apart rocks. Abrasion: Rocks are worn down by friction from wind, water, or rubbing against other rocks.
Two factors that play a significant role in this type of weathering are?
Temperature changes and presence of water play a significant role in weathering. Fluctuations in temperature can cause rocks to expand and contract, leading to physical weathering. Water can also seep into cracks in rocks, freeze, and expand, further breaking down the rock through a process known as frost wedging.

How does oxygen affect the earth and weathering?
By that it splits rocks and makes the oxygen go through it. When the temperature changes, the oxygen spreads into the rock and it cracks open.
What are the common causes of cracks and lines on a windshield?
Common causes of cracks and lines on a windshield include impact from rocks or debris, extreme temperature changes, and structural stress from improper installation or previous damage.
How do changes in temperature cause rocks to break down?
Changes in temperature cause rocks to undergo thermal expansion and contraction. When rocks heat up, they expand; likewise, when they cool down, they contract. Over time, this repeated expansion and contraction weaken the rock structure, creating cracks and fractures that eventually lead to rock breakdown.
Physical weathering is greatest under conditions of?
Physical weathering is greatest under conditions of frequent temperature changes and the presence of ice. This is because the expansion and contraction of rocks due to temperature changes, as well as the freezing and thawing of water in rock cracks, can lead to the breakdown of rocks into smaller pieces.
Describe how a vein of ore forms underground?
Hot fluids that get into the cracks and rocks and it cools and settles.

Why do rocks changes temperature?
Break apart
Water freezes in the cracks in rocks. plants grow into the cracks in rocks?
cracks open wider
Water freezes in the cracks of rocks and plants grow into the cracks of rocks what happens?
cracks open wider
What causes cracks in granite?
Cracks in granite can be caused by a variety of factors, including natural geological processes like stress from the Earth's crust, extreme temperature changes, or pressure from surrounding rocks. Additionally, improper handling during transportation, installation, or fabrication can also lead to cracks in granite.
