Best answer: Which do you think will weather at a faster rate sandstone or granite?

Is sandstone or granite weather faster?

Granite is packed much more densely than sandstone therefore granite is less susceptible to the weather than sandstone.

Which rock will weather at a faster rate?

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.

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.

Is sandstone easy to weather?

Sandstone is a sedimentary rock that is highly resistant to weathering. Other sedimentary rocks you will encounter are mudstone and siltstone. These are soft and easily weathered (lots in the Painted Desert). Yet another sedimentary rock you will see is limestone.

Does sandstone erode fast?

Silica cemented sandstone is very durable and hard. Calcite cemented sandstone is subject to acidic dissolution and is more easily eroded. Clay and gypsum cements, which are soft minerals, tend to produce much softer sandstone and the sand can sometimes be rubbed off in a person’s hands.

Does sandstone weather faster than limestone?

There are some rocks, like limestone, that weather more rapidly. Limestone has the compound calcite. … The mechanical weathering of rocks like shale and sandstone causes their grains to break up over time and become sand and clay particles.

How fast does granite weather?

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.

Which of the rocks will weather most rapidly Why?

Rocks made up of minerals such as feldspar, calcite, and iron, weather more quickly. 4. Pollution speeds up weathering.

How does granite turn into sandstone?

How does granite change into sandstone? Igneous rock granite formed beneath the surface millions of years ago. Then, the forces of mountain guilding slowly pushed the granite upward, forming a mountain. … Slowly, the sediments were pressed together and cemented to form sandstone, a sedimentary rock.

Which would Weather faster in a humid climate a quartz sandstone or an arkose explain your answer?

Since quartz is resistant to chemical weathering, it tends to concentrate in sand deposits as the less resistant minerals such as feldspar are weathered away. Sandstone with more than 25% of the grains consisting of feldspar is called arkose. … So arkose would weather faster in a humid climate than the quartz sandstone.
