How does topography affect weathering rates?
The specific rock type found at the surface has an important influence on the topography of a region. Certain rocks are able to resist weathering and erosion more easily than are others; resistant rocks that overlie weaker layers act as caps and form ridges.
How does local topography affect weathering?
The topography of an area can influence the weather and climate. Mountainous areas tend to have more extreme weather because it acts as a barrier to air movements and moisture. One side of mountain can be dry while the other side is full of vegetation. Mountains can cause a physical barrier to rain clouds.
What 2 factors affect the rate of weathering the most?
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.
What are 2 effects 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.
Does topography affect the rate of erosion?
The topographical factor. Although slope has a powerful influence on erosion, the presence of erosion and heavy runoff on gentle slopes (2% in the Sahel or on European uplands) indicates that this phenomenon can occur without any need for a steep slope: the action of rain is enough (Fauck 1956, Fournier 1967).
How does topography affect soil formation?
Topography has a strong influence on soil development. Soils on the side of hills tend to be shallow, due to erosional losses. Soils on the tops of hills tend to be deep, but lighter in color, due to downward leaching losses. Soils in the valleys tend to be deeper, darker, and contain more horizons.
What are 2 topographic features that can affect the climate of a region?
It can include mountains, rivers, or cities. Topographical features like mountains affect the weather mostly in the way that they direct air currents. For example, air is forced to rise over mountains. Moist air will cool as it rises, and then the clouds release the water, causing precipitation like rain or snow.
What are two rock characteristics that affect the rate of weathering?
Name two rock characteristics and two climatic factors that affect the rate of weathering. Rock characteristics include cracks and mineral composition; climatic factors include temperature and moisture.
What are the 3 effects of weathering?
These are landslides, mud flow, earth flow and sheets wash. Formation of various landforms: Due to weathering of rocks different landforms are formed like sea arches, stacks, mushroom rocks etc.
What are the topographic factors?
Topographic factors include height, direction of slope, steepness of the slope. The topographic factors are also called indirect factors as they influence the growth and development of organisms by bringing variations in climatic factors.
How does surface area affect the rate of weathering?
Secondly, how does surface area affect the rate of weathering? When the amount of surface area relative to volume increases, the rate of weathering increases. weathered it can increase the surface area of the rock. This means that more of the rock is exposed to chemical weathering. Therefore, the rate of chemical weathering will increase.
How does the topography of the Earth affect the weather?
The topography of Earth’s surface is one of the primary factors that causes our daily weather. Changes in elevation, especially around high mountain ranges, determine the distribution of precipitation on our planet.
What makes a rock more susceptible to weathering?
A rock’s structure also affects its susceptibility to weathering. Massive rocks like granite generally to not contain planes of weakness whereas layered sedimentary rocks have bedding planes that can be easily pulled apart and infiltrated by water. Weathering therefore occurs more slowly in granite than in layered sedimentary rocks. 1.
Why does granite weather more slowly than sedimentary rocks?
Weathering therefore occurs more slowly in granite than in layered sedimentary rocks. 1. Rainfall and temperature can affect the rate in which rocks weather. High temperatures and greater rainfall increase the rate of chemical weathering. 2.
