The grass growing through a crack in a sidewalk can contribute to physical weathering by exerting pressure on the concrete as the roots expand, potentially widening the crack. Additionally, the roots can facilitate chemical weathering as they release organic acids that can weaken the sidewalk's structure over time. Ultimately, this combination of physical and chemical weathering can lead to further deterioration of the sidewalk.
What else can I help you with?
All of this sun and heat is making you thirsty You decide to walk down the street to the food stand to buy some lemonade As you are walking you notice big cracks in the sidewalk What caused them?
The cracks in the sidewalk are likely caused by a combination of factors, including weathering from temperature changes, tree roots growing beneath the concrete, and general wear and tear from traffic and usage over time. Additionally, poor construction or maintenance practices can also contribute to the formation of cracks in the sidewalk.
Is mechanical weathering caused by ice and growing roots?
Yes. Mechanical weathering is the breaking of rocks into smaller rocks by physical means. Ice can do this in a process called ice wedging or frost wedging. Plants can do this by their roots growing into cracks in the rocks.
Is moss growing on the surface of rock producing pits in the rock chemical weathering?
Yes, moss growing on the surface of a rock can contribute to chemical weathering. As mosses grow, they produce organic acids that can break down minerals in the rock, leading to the formation of pits and crevices. Over time, this process can weaken the rock and contribute to its overall weathering and erosion.
What term best identifies the type of weathering represented by a?
The term that best identifies the type of weathering represented by a salt crystal growing in a crack in a rock is mechanical weathering. This occurs when physical forces, such as the growth of salt crystals, exert pressure on rocks causing them to break apart or crack.
What kind of weathering is caused by lichen?
Lichen contribute to chemical weathering by releasing acids that break down rock surfaces. They also can physically weather rocks by growing into cracks and crevices, causing them to break apart through a process called biological weathering.
What are the normal everyday mushroom that you see growing on the side of the sidewalk called?
dinner

Additionally, poor construction or maintenance practices can also contribute to the formation of cracks in the sidewalk.
Is grass poking through a crack in a sidewalk an example of primary succession or secondary succession?
Grass poking through a crack in a sidewalk is an example of secondary succession. This is because the sidewalk already existed, and the grass is growing after a disturbance (such as the cracking of the sidewalk) has occurred, allowing for new plant growth in the area.
How might the grass growing up through a crack on a sidewalk affect the side walk?
pringles
What is the length of one sidewalk square?
This probably varies from city to city, and building code to building code. When I was growing up in the city of Detroit, sidewalk squares were 5' x 5'.
How might the grass growing up through a crack in a sidewalk affect the sidewalk?
The roots of the grass may further widen the crack in the sidewalk as it grows, causing potential trip hazards. Additionally, as the grass grows, it can retain moisture which may lead to further deterioration of the sidewalk over time. If left unchecked, the grass can also make the sidewalk more slippery when wet.
Is mechanical weathering caused by ice and growing roots?
Yes. Mechanical weathering is the breaking of rocks into smaller rocks by physical means. Ice can do this in a process called ice wedging or frost wedging. Plants can do this by their roots growing into cracks in the rocks.
What type of weathering does plant cause?
Plants can cause mechanical weathering by growing into cracks in rocks and breaking them apart as their roots expand. They can also cause chemical weathering by releasing acids and other compounds that break down the minerals in rocks.
Is moss growing on the surface of rock producing pits in the rock chemical weathering?
Yes, moss growing on the surface of a rock can contribute to chemical weathering. As mosses grow, they produce organic acids that can break down minerals in the rock, leading to the formation of pits and crevices. Over time, this process can weaken the rock and contribute to its overall weathering and erosion.
How does chemical weathering differ from machanical weathering?
Chemical weathering involves the breakdown of rocks through chemical processes such as oxidation or hydrolysis, which alter the composition of the rocks. Mechanical weathering, on the other hand, involves the physical breakdown of rocks into smaller pieces through processes like frost wedging or roots growing into cracks.
Students examined a large crack found in a boulder where a tree was growing. which kind of process were the students observing?
Weathering
What term best identifies the type of weathering represented by a?
The term that best identifies the type of weathering represented by a salt crystal growing in a crack in a rock is mechanical weathering. This occurs when physical forces, such as the growth of salt crystals, exert pressure on rocks causing them to break apart or crack.
