Which condition leads to a slower rate of weathering quizlet?
The dry climate promotes a slower rate of weathering.
What climate has the slowest rate of weathering?
hot, dry climates The slowest rates of weathering occur in hot, dry climates. The lack of water limits many weathering processes, such as carbonation and ice wedging.
Which condition leads to a slower rate of weathering high Temperatureso hard Mineralso cold Climatesoporous rocks?
Cold climates favor mechanical weathering. Chemical reactions occur slower at higher temperatures. The chemical reaction rates of minerals are not impacted by temperature.
What 3 things affect the rate of weathering?
Rocks that are fully exposed to the atmosphere and environmental elements, such as wind, water and temperature fluctuations, will weather more rapidly than those covered by ground. Another factor that affects the rate of weathering is the composition of rock.
Which condition leads to a slower rate of weathering porous rocks cold climates hard minerals high temperatures quizlet?
Cold climates favor mechanical weathering. Chemical reactions occur slower at higher temperatures. Lower precipitation levels lead to more chemical reactions. The chemical reaction rates of minerals are not impacted by temperature.
How does cold & dry climate slow rate of chemical weathering?
Chemical, Physical and Biological Weathering Physical weathering occurs more often in cold climates, because the different minerals within rocks expand and contract at different rates when they are heated and cooled. Repeated heating and cooling cycles eventually cause rocks to fracture.
Which rock weathers most slowly?
They are sheet silicate minerals like micas. Quartz chemically weathers only very, very slowly because of its high stability. It is mostly just broken down into small, sand-sized and smaller particles. Rock fragments will also remain where the rocks are not completely weathered.
Which condition leads to a slower rate of weathering O porous rocks O cold climates o Hard minerals o high temperatures?
Cold climates favor mechanical weathering. Chemical reactions occur slower at higher temperatures. Lower precipitation levels lead to more chemical reactions. The chemical reaction rates of minerals are not impacted by temperature.
Which factors affect weathering?
Factors affecting weathering
- Mineral composition.
- Grain (Particle) size.
- Presence of lines of weakness.
- Climate.

Which mineral would weather at a slower rate when exposed to abrasion?
ROCK COMPOSITION- Some minerals resist weathering. Quartz is a mineral that weathers slowly. Rocks made up of minerals such as feldspar, calcite, and iron, weather more quickly.
How does temperature affect the rate of weathering?
Temperature changes can also contribute to mechanical weathering in a process called thermal stress. Changes in temperature cause rock to expand (with heat) and contract (with cold). As this happens over and over again, the structure of the rock weakens. Over time, it crumbles.
Is weathering a fast or slow process?
Most weathering, however, is a slow process that happens over thousands or millions of years. The speed at which weathering and erosion take place depends on the type of material that is being worn away. Some hard rock, like granite, wears away slowly, while softer rock like limestone, wears away much more quickly.
How does climate affect the rate of weathering?
In general, hot wet climates accelerate chemical weathering while cold dry climates accelerate physical weathering. Although the rate of weathering depends on the type of rock, rocks in tropical climates experience the highest rates of weathering because of the combination of high heat and heavy rainfall.
What are the rates of weathering?
The weathering rate for rocks depends on the composition of the rock; the climate of the area; the topography of the land; and the activities of humans, animals, and plants. A rock's composition has a huge effect on its weathering rate. Rock that is softer and less weather-resistant tends to wear away quickly.
What are the 4 factors that affect the rate of weathering?
Factors affecting weathering
- rock strength/hardness.
- mineral and chemical composition.
- colour.
- rock texture.
- rock structure.

What increases the rate of weathering?
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. It occurs very slowly in hot and dry climates.
