What is a major factor in differential weathering?

What are factors that cause differential weathering?

What are two factors that cause differential weathering? 2. the variation in the number of cracks and spacing of cracks in different parts of the rock.

  • control frequency of freeze thaw cylces.
  • rate of chemical weathering.
  • kind and amount of vegetation present.

What is differential weathering?

the difference in degree of discoloration, disintegration, etc., of rocks of different kinds exposed to the same environment.

What are the 4 main factors influencing weathering?

Although many factors combine to influence weather, the four main ones are solar radiation, the amount of which changes with Earth’s tilt, orbital distance from the sun and latitude, temperature, air pressure and the abundance of water.

Which is a factor of mechanical weathering?

Many factors contribute to the effect, such as the geometry of cracks, porosity and strength of rocks, rate of cooling, water content in rock pore space, transportation of water to ice formation, etc., are involved that weathering due to ice is exceedingly complicated and a number of hypotheses have been advanced to …

What factor is the most powerful cause of mechanical weathering?

Frost Wedging

As water seeps into rock cracks and crevices, cold temperatures can cause the water to freeze, resulting in ice deposits that expand and exert pressure on the rock. According to Missouri State University, frost wedging is the most abundant form of mechanical weathering.

What is differential weathering quizlet?

differential weathering. the process by which softer less weather resistant rocks wear away and leave more weather resistant rocks behind. ice wedging. when water goes into the cracks of a rock, then freezes, then expands. soil.

Where does differential weathering occur?

Weathering that occurs at different rates, as a result of variations in composition and resistance of a rock or differences in intensity of weathering, and usually resulting in an uneven surface where more resistant material protrudes above softer or less resistant parts.

What is the major distinction between internal and external earth?

What is the major distinction between internal and external Earth processes? Internal processes are driven by the Earth’s internal heat energy and external processes are driven by energy from the Sun.

Why does differential weathering occur quizlet?

Why does differential weathering occur? Different minerals have different resistances to weathering. If the climate in an area has very little rainfall, what would the characteristics of the soil in the area be?

What is differential rock?

Differential Weathering. Different rock masses, or different sections of the same rock, weather at different rates, simply because they are formed of different minerals. This variation is known as differential weathering.
