Which type of weathering is likely in acid rain falling on a headstone in a cemetery?
Chemical Weathering
What causes headstones to turn black?
The reason is most likely algae, lichen, moss, mold, or mildew growth and stains. These growths develop on the surface, making headstones and memorials look dark and dirty.
What factors might influence the rate of chemical weathering of gravestones?
Rainfall and temperature can affect the rate in which rocks weather. High temperatures and greater rainfall increase the rate of chemical weathering. 2. Rocks in tropical regions exposed to abundant rainfall and hot temperatures weather much faster than similar rocks residing in cold, dry regions.
How does weathering affect Mount Rushmore?
At Mt. Rushmore, the massive monument experiences hundreds of tiny cracks thanks to the effects of weathering. Without proper restoration, these cracks would widen over time, crumbing the famous presidential faces that make up the structure.
What are the two things that affect the rate of weathering?
The two factors that affect the rate of weathering are the rock’s type and the climate. If a rock is permeable, it weathers easily. The mineral content of the rocks influence how fast it would weather.
Which weather is fastest?
1. CLIMATE: The amount of water in the air and the temperature of an area are both part of an area’s climate. Moisture speeds up chemical weathering. Weathering occurs fastest in hot, wet climates.
Which rock is more resistant to weathering?
Igneous rocks
Which is the best example of chemical weathering?
With chemical weathering of rock, we see a chemical reaction happening between the minerals found in the rock and rainwater. The most common example of hydrolysis is feldspar, which can be found in granite changing to clay. When it rains, water seeps down into the ground and comes in contact with granite rocks.
What are 4 examples of physical weathering?
Some examples of physical weathering mechanisms:
- Frost wedging. Frost wedging happens when water filling a crack freezes and expands (as it freezes, water expands 8 to 11% in volume over liquid water).
- Heat/Cold Cycles.
- Unloading.
