Which rock would weather faster in a warm and humid climate granite or marble Why?

In an arid, temperate climate, mechanical weathering in the form of abrasion from windblown sand might be more prevalent than in a humid, temperate climate. This would lead to more mechanical weathering of marble than of granite because of the differences in the hardness of their constituent minerals.

Is marble more resistant to weathering than granite?

Marble is composed of calcite, a mineral strongly resistant to weathering, whereas granite is composed of quartz, a mineral strongly reactive in water. Marble is composed of a mineral that readily reacts with water (calcite), whereas granite is composed of minerals more resistant to weathering (like quartz).

Which weathering is more effective in humid climates?

Explanation: chemical weathering is more effective in humid climates because it requires moisture.

Why is there more chemical weathering in humid climates?

Chemical weathering generally takes place in hot and humid areas where there is a lot of water. This is because water is important to many of the chemical reactions that can take place.

Is marble susceptible to weathering?

Although most marble varieties are simple from a mineralogical standpoint (essentially composed of calcite or dolomite), the anisotropic thermal expansion of the constituent minerals make them susceptible to physical weathering as a result of temperature changes [1] .

What type of rock is marble?

The main difference between limestone and marble is that limestone is a sedimentary rock, typically composed of calcium carbonate fossils, and marble is a metamorphic rock.

Why does granite weather faster than marble?

Why does granite weather faster than marble? Marble is composed of a mineral that readily reacts with water (calcite), whereas granite is composed of minerals more resistant to weathering (like quartz). 鈥 Marble is composed of minerals that resist weathering well, whereas granite has less of these minerals.

What weathering affects granite?

How is granite affected by weathering? Chemical weathering of granite occurs when dilute carbonic acid, and other acids present in rain and soil waters, alter feldspar in a process called hydrolysis.

What types of weathering affect granite?

Weathering Process of Granite
Cooling. Granite cools slowly within the Earth’s crust. Wind. Wind, water and ice denude the soil and Earth’s crust overlying the granite mass, exposing it to the atmosphere. Hydrolysis. Quartz.

Why do rocks weather faster in wet climates than in dry climates?

Wet climates accelerate the rates of chemical weathering, caused when C02 in dirt mixes with air and water to form a weak acid. The weak acid breaks down rocks more rapidly in wet climates compared with dry ones.

Why is mechanical weathering predominant in hot desert?

Answer: The arid or hot desert areas dominated by mechanical weathering. Due to the high diurnal range of temperature in the arid areas, repeated expansion and contraction of the outer layer of the rock takes place.

Which weathering is most common in equatorial and tropical regions?

chemical weathering is the right answer.

How does climate affect weathering of rocks?

Rainfall and temperature can affect the rate in which rocks weather. High temperatures and greater rainfall increase the rate of chemical weathering. Minerals in a rock buried in soil will therefore break down more rapidly than minerals in a rock that is exposed to air.

Which climate conditions will cause the fastest chemical weathering of granite sandstone and shale?

B. Warm and wet. Explanation: The chemical reactions that break down granite, sandstone, and shale all occur most quickly when the temperature is warm. Because these reactions require water, chemical weathering is fastest in wet climates.

Does humidity affect weathering?

New study by University of North Carolina confirms that increased humidity in air and rising temperatures leads to rocks weathering faster. This is a part of the carbon cycle on earth, where carbon takes about 100 to 200 million years to move between rocks, soil, water and atmosphere.

Is granite resistant to weathering?

Differential Weathering

Granite is extremely resistant and sandstone a little less so due to the percentage of quartz that each rock type contains. A gravestone made of granite will therefore resist fracturing, cracking and chipping longer than a sandstone marker found in the same location.

What type of weathering affects marble?

Marbles as building stones as well as in their natural environments show complex weathering phenomena. Therefore, the rock fabric and especially the lattice-preferred orientation (texture) of calcite and/or dolomite as the predominant mineral phases in marbles have a significant influence on the mechanical weathering.

Why is marble metamorphic?

Marble is a metamorphic rock that forms when limestone is subjected to the heat and pressure of metamorphism. Under the conditions of metamorphism, the calcite in the limestone recrystallizes to form a rock that is a mass of interlocking calcite crystals.
