How does slope affect the rate of weathering?
Slope The steep sides of mountains and hills make water flow down them faster. Fast-moving water has more energy to break down rock than slow-moving water. Therefore, rocks on steep slopes can weather faster than rocks on level ground.
What factors affect the rate of erosion?
Major factors that affect the amount of erosion are soil cloddiness, surface roughness, wind speed, soil moisture, field size, and vegetative cover. A discussion of each follows. The cloddiness of a given soil largely indicates whether the wind will erode it.
What are the most important factors in determining the rate of weathering?
The most important factors that determine the rate at which weathering occurs are the type of rock and the climate. Some types of rock weather more rapidly than others. For example, some rock weathers easily because it is permeable, which means that it is full of air spaces that allow water to seep through it.
What are the six factors that affect the rate of weathering quizlet?
The causes of mechanical weathering include freezing and thawing, release of pressure, plant growth, actions of animals, and abrasion. The causes of chemical weathering include the action of water, oxyen, carbon dioxide, living organisms, and acid rain.
What are the two most common forms of weathering?
The two main types of weathering are physical and chemical weathering. This page describes mechanical (physical) weathering (and more).
What is the effect of weathering?
The effects of weathering disintegrate and alter mineral and rocks near or at the earth’s surface. This shapes the earth’s surface through such processes as wind and rain erosion or cracks caused by freezing and thawing.
What makes the two types of weathering different from each other?
Over time, this can lead to erosion, in which huge sections of rock and stone are carried away, changing landscapes. Physical weathering alters the material structure of rocks, while chemical weathering alters their chemical structure.
What three factors affect the rate of weathering and erosion?
What are the 3 factors that affect the rate of weathering?
- Mineral Composition. One type of weathering, known as chemical weathering, works at different rates depending on the chemical composition of affected rocks.
- Type of Lattice.
- Temperature.
- Water and Salt.
What are the 4 factors that affect the rate of soil erosion?
The key climatic characteristics influencing erosion processes in a given territory include atmospheric precipitation, wind, air temperature, air humidity and solar radiation. The factors having a direct effect on soil erosion are atmospheric precipitation (water erosion) and wind (wind erosion).
What are the factors that affect physical weathering?
Physical weathering can occur due to temperature, pressure, frost, root action, and burrowing animals. For example, cracks exploited by physical weathering will increase the surface area exposed to chemical action, thus amplifying the rate of disintegration.
How does rock type affect weathering?
Certain types of rock are very resistant to weathering. Igneous rocks, especially intrusive igneous rocks such as granite, weather slowly because it is hard for water to penetrate them. Other types of rock, such as limestone, are easily weathered because they dissolve in weak acids.
How does topography affect weathering?
Imagine changes in elevation of landscape over a larger area, for example, mountains, hills, lakes and valleys. More specifically speaking, topography aids in changing precipitation and temperature. A general rule of thumb in understanding weather is warm air rises and cold air sinks.
What is the effect of topography on weathering?
What two factors affect wind erosion?

What are the 4 main causes of erosion?
Four Causes of Soil Erosion
- Water. Water is the most common cause of soil erosion. …
- Wind. Wind can also make soil erode by displacing it. …
- Ice. We don’t get much ice here in Lawrenceville, GA, but for those that do, the concept is the same as water. …
- Gravity. …
- Benefits of a Retaining Wall.
What is erosion and factors affecting erosion?
Factors such as rainfall, runoff, wind soil, slope, plant cover and presence or absence of conservation measures are responsible for soil erosion. But mainly three following factors affect the erosion. 1. Energy: … in case of water erosion and wind breaks or shelter belts incase of wind erosion.
What two climatic factors are most important in the weathering process?
There are two factors that play in weathering, viz. Temperature and Precipitation. Warm climates affect by chemical weathering while cold climates affect by physical weathering (particularly by frost action). In either case the weathering is more pronounced with more moisture content.
What two factors determine the type of rock particles and minerals in any given soil?

What affects the rate of weathering quizlet?
The rate of weathering is fastest in climates where the temperature rises and falls below freezing. As water freezes and thaws in rocks, it causes ice wedging. … A rock’s surface area determines how much of the rock is exposed. The more rock that is exposed, the higher the rate of weathering.
Which is least affected by chemical weathering?
Quartz, which is crystalline silica, is the only common mineral that is not strongly affected by chemical weathering. It does not dissolve in water. All other common minerals are either dissolved completely or are partially dissolved and reduced to clay.
What are the two basic process of weathering briefly discuss each process?
Two important classifications of weathering processes exist – physical and chemical weathering; each sometimes involves a biological component. Mechanical or physical weathering involves the breakdown of rocks and soils through direct contact with atmospheric conditions, such as heat, water, ice and pressure.
What are the two basic categories of weathering how do the products of each category of weathering differ?
How do the products of the two categories of weathering differ from each other? Mechanical weathering results in broken pieces that are of the same composition as the original material, whereas chemical weathering alters the composition of the material.
What are the 3 types weathering?
There are three types of weathering, physical, chemical and biological.
