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 else can I help you with?
Which to rock units appear to be most resistant to weathering erosion?
Metamorphic rocks such as quartzite and marble tend to be most resistant to weathering and erosion due to their highly compacted and recrystallized nature. These rocks have undergone intense heat and pressure, which makes them more durable and less prone to breaking down compared to sedimentary or igneous rocks.
What is the rock that is most resistant to weathering is?
Granite is one of the most resistant rocks to weathering due to its composition of hard minerals like quartz and feldspar. Its interlocking crystal structure makes it more durable against physical and chemical weathering processes compared to other rocks.
What mineral in granite rock hardly weathers?
Quartz is a mineral found in granite that is highly resistant to weathering, making it one of the most durable components of the rock. It retains its crystal structure and resists chemical breakdown over long periods of time.
Where is chemical weathering most active?
Chemical weathering is most active in warm and humid climates where there is abundant rainfall. These conditions promote the breakdown of minerals in rocks through chemical reactions, leading to the alteration of rock formations over time. Areas like tropical rainforests and coastal regions experience high levels of chemical weathering.
Which substance is most resistance to weathering rock or sand?
Rock is more resistant to weathering than sand because of its larger particle size and greater cohesion between particles. Sand is easily transported by wind and water, leading to faster erosion and weathering.

Under most weathering conditions which mineral in granites and rhyolites would be most resistant to decomposition?
Quartz is the mineral in granites and rhyolites that is most resistant to decomposition under most weathering conditions due to its chemical and physical stability. Quartz is less susceptible to chemical weathering compared to minerals like feldspar and biotite, which are more commonly altered to clay minerals.
Which substance is most resistance to weathering?
give example of a real life situation where a substance's resisrance to weathering might make a difference
What mineral in granite rock hardly weathers?
Quartz is a mineral found in granite that is highly resistant to weathering, making it one of the most durable components of the rock. It retains its crystal structure and resists chemical breakdown over long periods of time.
Is quartz resistant to weathering and is it an important component of sands in river beds?
Yes, quartz is resistant to weathering and is one of the most abundant minerals in Earth's crust. It is a major component of sands found in river beds due to its hardness and resistance to erosion, making it a significant contributor to sedimentary deposits formed by weathering and erosion processes.
Which mineral is the most stable at the Earth's surface?
Quartz is one of the most stable minerals at the Earth's surface. It is resistant to weathering and can be found in sedimentary, igneous, and metamorphic rocks.

Which characteristic most determines a rocks resistance to weathering?
The mineral composition of the rock is the most important factor in determining its resistance to weathering. Rocks made up of harder minerals such as quartz or feldspar are generally more resistant to weathering compared to rocks with softer minerals like calcite or gypsum. Additionally, the presence of cementing materials can also affect a rock's weathering resistance.
What is likely to be most affected by weathering caused by wind?
Rock formations, building exteriors, and soil erosion are all likely to be most affected by weathering caused by wind. Wind can break down rocks and structures over time through mechanical weathering, as well as erode soil by carrying away particles.
Is quartz affected by chemical weathering?
Yes, quartz is relatively resistant to chemical weathering because it is composed of silica, which is a very stable mineral. However, prolonged exposure to certain acids or alkaline substances can slowly dissolve quartz over time.
