Why is chemical weathering a bigger problem today then it was 100 years ago?
Chemical weathering is a bigger problem today due to human activities that have increased the release of pollutants into the atmosphere. Industrial processes, such as burning fossil fuels, have released higher levels of pollutants like sulfur and nitrogen oxides, which when combined with water in the atmosphere forms acid rain. Acid rain accelerates chemical weathering, leading to the degradation of rocks, buildings, and monuments at a faster rate than 100 years ago.
Is oxidation a chemical or mechanical weathering?
another gas found in air, carbon dioxide, also causes chemical, weathering. Carbon dioxide dissolves in rainwater and in water that sinks through air pockets in the soil. The result is a weak acid called carbonic acid. Carbonic acid easily weathers rocks such as marble and limestone.
Why will a rock weather faster after it's been crushed?
Crushing a rock increases its surface area exposed to weathering agents like air and water. This accelerated exposure allows for more chemical reactions to occur, leading to faster weathering of the rock.
Soil is formed from?
Soil is formed from the weathering of rocks over time. This process involves the breakdown of rocks into smaller particles due to physical (such as freeze-thaw cycles) and chemical (such as acid rain) actions, along with the addition of organic matter from decaying plants and animals.
What are the most important factors that effect weathering?
wind, as wind can weather rocks pretty quick heat, when a rock gets hot, it expands, at night it cools down. this causes pieces to flake away this is called onionskin weathering water, water flow and when water freezes in a crack in a rock, the ice expands causing the crack to get bigger and eventually break of this ice called freeze-thaw weathering Water is the most important agent in chemical weathering. Rain disolves some carbon dioxide as it falls through the atmosphere, so normal rain water is mildly acidic. Water in the soil also disolves carbon dioxide released by decaying organic matter. The result is that acidic water is everywhere on Earth's surface.
Why is chemical weathering of the Saint Paul's Cathedral a bigger problem now than it was 100 years ago?
Because nowadays there is lots of pollution etc because of all the electronics and energy wasted Well, its something like that.
How do you make a crack rock bigger?
chemical weathering.
Which is bigger a church or a cathedral?
Usually a cathedral.

Is a basilica bigger than a cathedral?
A Basilica is indeed bigger than a Cathedral. The Rank goes: Church, Cathedral, and finally Basilica. The Vatican is a Basilica.
How do holes in rocks get bigger?
Holes in rocks can get bigger through weathering processes such as freeze-thaw cycles, water erosion, chemical weathering, and biological activity. These processes can gradually wear away the rock material around the hole, causing it to expand over time.
Why is the sediment load in a river an indicator of the amount of weathering and erosion?
Because the bigger the load is, more weathering and erosion there is. The less of it means less of weathering and erosion.

What is bigger peterborough cathedral or mollorca cathedral?
Peterborough Cathedral in the United Kingdom is larger than Mallorca Cathedral in Spain. Peterborough Cathedral is one of the largest cathedrals in Britain, measuring approximately 150 meters in length. In contrast, Mallorca Cathedral, also known as La Seu, is significantly smaller, measuring about 121 meters in length.

Crushing a rock increases its surface area exposed to weathering agents like air and water. This accelerated exposure allows for more chemical reactions to occur, leading to faster weathering of the rock.
What causes cracks in a rock to get bigger?
Weathering, specifically freeze-thaw weathering. If rain gets into the crack and freezes, it expands and pushes the crack wider.
Can physical weathering make a rock bigger?
Physical weathering is mechanical action which typically erodes rock faces. This invariably results in a smaller rock. Chemical weathering involves water absorption or other reactions. Mechanical heating and freezing can crack and fissure the rock, slightly increasing its size. In general, physical weathering is an abrading process, whether via water born sediment wearing away the rock, or wind blown particles sand blasting the rock, and these actions make reduce the rock's size.
