* Climate- Climate, which is usually measured in terms of temperature and moisture, can drastically affect the rate of weathering. High amounts of water and higher temperatures generally cause chemical reactions to run faster. Thus warm humid climates generally have more highly weathered rock, and rates of weathering are higher than in cold dry climates. Example: limestones in a dry desert climate are very resistant to weathering, but limestones in a tropical climate weather very rapidly. A high temperature and high amounts of water also controls vegetation which indirectly affects rate. Seasonality of precipitation affects rate to a degree. · Organisms (Biota) Animals- burrowing organisms like rodents, earthworms, & ants, bring material to the surface were it can be exposed to the agents of weathering.
* Time- Weathering is a slow process. When we speak of time in a geologic sense, millions of years are often used as the units. The bedrock of Greenland has barely been weathered, and its age is over 3.5 billion years. The longer that a rock has been exposed to the weather, the faster it weathers. * Mineral Composition- All chemical and physical properties are determined by the mineral composition of the rock. Mineral composition is more important in determining the rate of chemical weathering. Those minerals that are most reactive with acids, water, and air are weathered at a more rapid rate. Mineral composition also affects physical weathering. Minerals that are soft (hardness lower thaan six) can be easily abraided and blasted. Slope - On steep slopes weathering products may be quickly washed away by rains. On gentle slopes the weathering products accumulate. On gentle slopes water may stay in contact with rock for longer periods of time, and thus result in higher weathering rates.
· Porosity and faults and shears in materials Porous sediment equals better circulation and thus faster weathering process. Impermeable rocks will mean that no or little circulation will take place in rocks and weathering will be slower. Enhanced weathering rate occurs if faults and shears are present in rocks. * Exposure- Rock that is exposed to the atmosphere tends to weather much quicker. Bed rock that is covered by soil and vegetation may not weather as quickly. * Particle Size- The particle size of the material can affect the rate of weathering. The smaller the particle size, the faster it will weather. The more surface area that is exposed, the more it will weather.
What else can I help you with?
True or false the rate of mechanical weathering depends on the materials in a rockrock and conditions around it?
True. The rate of mechanical weathering depends on factors such as the type of rock and its properties, as well as the environmental conditions surrounding the rock, such as temperature, moisture, and the presence of vegetation or organisms. These factors can all influence the physical breakdown of the rock through mechanical weathering processes.
Which would dissolved more quickly chemical or mechanical weathering?
Mechanical weathering typically occurs more quickly than chemical weathering. Mechanical weathering involves the physical breakdown of rocks into smaller pieces, while chemical weathering involves the alteration of rocks through chemical reactions. Factors such as temperature, precipitation, and rock composition can influence the rate of weathering.
What are things that can affect the rate of weathering?
Weathering is the breaking down of rocks and soil, through natural or artificial means. It can be affected by several factors including the type of rock being broken down, the weathering agent that is breaking down the rock and even some human introduced factors like the presence of architecture.
What are the factors photosynthesis?
The intensity of light, concentration of carbon dioxide and temperature are the three main factors that affect photosynthesis. They determine the rate at which photosynthesis occurs.
Rate of weathering depends upon the area's what?
Well, weathering of rock indeed depends on all of the areas weather conditions! Precipitation levels are often given the main credit for rock weathering, however wind erosion, known as eolian erosion, can be very substantial, particularly in arid regions. So wind and water (including ice which is highly erosive), are the big two although even heat or the areas ambient temperature play a role.
The most of important factors in determining the rate of weathering are what?
The most important factors that determine the rate at which weathering occurs are the type of rock and the climate. Rainfall affects the rate of weathering.
What are two exposure factors that determine rate of weathering?
Two exposure factors that determine the rate of weathering are climate (temperature and precipitation) and the type of rock or minerals being exposed to weathering processes. Climate affects the frequency and intensity of weathering agents, while the chemical and physical characteristics of rocks influence their susceptibility to weathering.
What are 2 factors that affect the rate of weathering?
The most important factors that determine the rate at which weathering occurs are the type of rock and the climate. Rainfall affects the rate of weathering.
What factors determine th rate of weathering?
The factors that determine the rate of weathering include the type of rock or material being weathered, the climate of the region (temperature and precipitation), the presence of vegetation and soil cover, as well as human activities such as mining and construction. Chemical weathering is more prominent in warm and humid climates, while physical weathering is more common in cold and dry climates.
What are the most important factors that determine the rate of weathering rock?
The most important factors that determine the rate of weathering rock are the composition and fabric of the rocks and the physical and chemical environment to which the surface of the rock is exposed.
What factors affects the rate of weathering?
Some factors that affect the rate of weathering are the type of rock, the altitude and the climate.
What factors affect the rate weathering?
Some factors that affect the rate of weathering are the type of rock, the altitude and the climate.
What are the two factors that determine the rate of weathering?
The two main factors that determine the rate of weathering are the type of rock or material being weathered and the climate or environmental conditions in which the weathering is taking place. Different rocks and materials weather at different rates depending on their composition, and weathering is generally more rapid in areas with high levels of moisture and temperature fluctuations.
What three factors determine the type of soil that can develop in an area?
The three factors that determine the type of soil in an area are climate, organisms, and parent material. Climate influences the rate of weathering and decomposition, organisms contribute to the organic matter content, and parent material determines the mineral composition of the soil.
If three rocks have the same mass will the weathering rate be the same?
Not necessarily. Weathering rates would depend on the rock type, mineral composition, and density. These factors will determine a rock's resistance to acidic rainwater, freeze/thaw cycles, and abrasion.
Which of theses factors affect the rate of weathering?
cool
What factors affect the rate of mechanical weathering?
Factors that affect the rate of mechanical weathering include temperature fluctuations, presence of water, wind intensity, type of rock or mineral composition, and presence of vegetation or organisms that can contribute to physical breakdown of rocks.
