Does granite weather faster than marble?

Less rain means less carbonic acid and less carbonic acid means less chemical weathering. … 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 a mineral that readily reacts with water (calcite), whereas granite is composed of minerals more resistant to weathering (like quartz). … Marble is composed of minerals that resist weathering well, whereas granite has less of these minerals.

Is marble easily weathered?

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] .

Is granite easily weathered?

Rock and Mineral Type

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.

Does granite weather quickly or slowly?

Hard rocks, such as granite, weather more slowly than softer rocks, such as limestone. Differential weathering happens when softer rock weathers away and leaves harder, more resistant rock behind.

How long does it take for granite to weather?

Granitic and gneissic domes in the humid southeastern United States appear to eroding at about 10 m/My. Our data suggest that granite, exposed in a variety of tectonic and non-glacial climatic settings, erodes quite slowly — on the order of a meter to perhaps a few tens of meters in a million years.

Which rock weathers most slowly?

Quartz is a mineral that weathers slowly. Rocks made up of minerals such as feldspar, calcite, and iron, weather more quickly. 4.

What does acid rain do to granite?

Acid rain speeds weathering through its chemical reaction with calcium carbonate. The acid rain, in turn, damages the stone, leaving a rough, pitted surface and making writing and art harder to distinguish.

What material is most resistant to weathering?

Sandstone is a sedimentary rock that is highly resistant to weathering. Other sedimentary rocks you will encounter are mudstone and siltstone.

Why does Marble weather more readily than granite quizlet?

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

What causes granite to weather?

Wind. Wind, water and ice denude the soil and Earth’s crust overlying the granite mass, exposing it to the atmosphere. The rock expands and contracts in reaction to changes in temperature. It shatters on the surface and the fractures widen to form crevices.

What happens to granite over time?

Granite tends to sit abundantly within the continental crust of the Earth. Sedimentary rock formations cover granite. Over time, the sedimentary rocks may move or they might erode away. When this happens, the granite becomes exposed.

What rock type is most easily weathered Why?

What rock type is most easily weathered? … Sedimentary rocks because they contain calcite and are harder. How is surface area related to weathering? The more surface area there is, the higher amount of weathering will occur.

Which rock weathers most quickly?

Sedimentary rocks usually weather more easily. For example, limestone dissolves in weak acids like rainwater. Different types of sedimentary rocks can weather differently.

Which rock weather is fastest?

Mafic silicates like olivine and pyroxene tend to weather much faster than felsic minerals like quartz and feldspar. Different minerals show different degrees of solubility in water in that some minerals dissolve much more readily than others.

Which rock will weather faster granite or basalt?

Basalt weathers faster than granite because it is not as hard and it’s easier for outside substances to impact and manipulate its structure.
