Which type of rock appear to be the least resistant to weathering and erosion?
Sedimentary rocks like sandstone and limestone tend to be less resistant to weathering and erosion compared to igneous or metamorphic rocks. Their softer composition and structure make them more susceptible to the effects of these processes.
Which rocks are most susceptible to biological weathering and why?
Sedimentary rocks like limestone and sandstone are most susceptible to biological weathering because they contain minerals that are easily broken down by organic acids produced by living organisms like plants and bacteria. These acids can dissolve the minerals in the rocks, leading to their breakdown and weathering.
What are less resistant rocks?
Less resistant rocks include sandstone, chalk, and limestone. These rocks are more susceptible to weathering and erosion compared to harder rocks like granite and basalt.
Which formations appear to be the most resistant to weathering?
Igneous rocks are typically the most resistant to weathering due to their dense and crystalline structure. Metamorphic rocks can also be highly resistant depending on the degree of recrystallization they have undergone. Sedimentary rocks like sandstone and limestone are generally more susceptible to weathering compared to the other two types.
The mineral in igneous rock that is least affected by chemical weathering is?
Quartz is the mineral in igneous rocks that is least affected by chemical weathering. It is physically and chemically resistant, making it more stable and less susceptible to weathering compared to other minerals like feldspar.
Why is limestone least resistant to weathering and erosion?
It is susceptible to chemical weathering more than other rocks from exposure to naturally acidic rainfall and groundwater.

What are less resistant rocks?
Less resistant rocks include sandstone, chalk, and limestone. These rocks are more susceptible to weathering and erosion compared to harder rocks like granite and basalt.
Can limestone be worn away?
Yes, limestone can be worn away over time through processes like erosion and weathering. Physical forces such as wind, water, and ice can gradually break down limestone rocks, leading to their erosion and the formation of features like caves, sinkholes, and limestone pavements.

Igneous rocks are typically the most resistant to weathering due to their dense and crystalline structure. Metamorphic rocks can also be highly resistant depending on the degree of recrystallization they have undergone. Sedimentary rocks like sandstone and limestone are generally more susceptible to weathering compared to the other two types.
What rocks are highly susceptible to chemical weathering through acid rain?
Rocks that are highly susceptible to chemical weathering through acid rain include limestone, marble, and some types of sandstone. These rocks contain minerals like calcite and dolomite that easily react with the acids in rainwater, leading to erosion and dissolution. Over time, acid rain can cause these rocks to deteriorate and lose their structure.
What type of carbonate rocks are susceptible to karst weathering?
Limestone and dolostone are the primary types of carbonate rocks susceptible to karst weathering. These rocks are composed mainly of calcium carbonate (in limestone) or magnesium carbonate (in dolostone), which can easily dissolve in acidic conditions, often created by carbonic acid from rainwater. This dissolution process leads to the formation of characteristic karst features such as sinkholes, caves, and underground drainage systems. The extent of karst development depends on factors like rock composition, topography, and climate.
What examples of rocks are easily weathered and rocks that are resistant to weathering?
limestone,sandstone,and shale
The mineral in igneous rock that is least affected by chemical weathering is?
Quartz is the mineral in igneous rocks that is least affected by chemical weathering. It is physically and chemically resistant, making it more stable and less susceptible to weathering compared to other minerals like feldspar.
What rocks are caused by weathering?
Some rocks commonly formed by weathering include sandstone, shale, and limestone. Sandstone is formed from the accumulation of sand grains cemented together, shale from the compaction of mud and clay, and limestone from the precipitation of calcium carbonate. These rocks can be broken down and altered by various weathering processes such as mechanical, chemical, and biological weathering.
What are examples of rocks that are easily weathered and rocks re resistant to weathering?
Examples of rocks that are easily weathered include limestone, sandstone, and shale, which are sedimentary rocks. Rocks that are resistant to weathering include granite, basalt, and quartzite, which are igneous and metamorphic rocks that have a more crystalline structure and are less prone to chemical breakdown from weathering processes.
