Which are all the result of weathering?
A.extinct species, broken windows, rusted bicycles
B.peeling house paint, broken windows, potholes in streets
C.rusted bicycles, peeling house paint, cracks in sidewalks
D.potholes in streets, extinct species, cracks in sidewalks
B. peeling house paint, broken windows, potholes in streets
The correct answer is C) rusted bicycles, peeling house paint, and cracks in sidewalks.
The correct answer is B. peeling house paint, broken windows, potholes in streets.
Weathering refers to the process by which rocks, minerals, and other materials on the Earth's surface are broken down and altered over time by various environmental factors, such as temperature changes, water, wind, and ice. The effects of weathering can be observed in different forms.
To identify the correct answer, we need to understand the processes involved in weathering and how they affect various objects or structures. Let's break down each option and determine which ones are a direct result of weathering:
Option A:
- Extinct species: This is not directly related to weathering. Extinction refers to the disappearance of a species from the Earth due to various factors such as habitat loss, climate change, or human activities.
- Broken windows: Although weathering processes like wind and temperature changes may contribute to the deterioration of window frames, the breaking of windows is primarily caused by external factors, such as physical impact or vandalism.
- Rusted bicycles: Rusting occurs due to the chemical reaction between iron and oxygen in the presence of moisture. While weathering can contribute to the rusting of bicycles by providing the necessary moisture, the main cause is the oxidation process.
Option B:
- Peeling house paint: Weathering, particularly due to moisture and temperature changes, can cause the paint on the exterior of a house to deteriorate and peel off over time.
- Broken windows: As mentioned earlier, broken windows are not a direct result of weathering.
- Potholes in streets: Weathering can play a significant role in the formation of potholes. Water seeps into cracks in the pavement, freezes, and expands, causing the asphalt to crack and disintegrate over time.
Option C:
- Rusted bicycles: As discussed earlier, rusting is influenced by weathering, but it is not the sole outcome.
- Peeling house paint: This is another outcome of weathering, as explained in option B.
- Cracks in sidewalks: The formation of cracks in sidewalks can be attributed to weathering processes, such as freeze-thaw cycles or the expansion and contraction of materials due to temperature changes. However, this option does not mention potholes.
Option D:
- Potholes in streets: This is a direct result of weathering, as explained in option B.
- Extinct species: This is not a result of weathering but rather a result of environmental changes or human activities.
- Cracks in sidewalks: This is a result of weathering, as mentioned in option C.
In conclusion, option B (peeling house paint, broken windows, potholes in streets) correctly identifies the outcomes that can be attributed to weathering.
