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.
Describe how the conditions under which rocks form affect the physical stability of rocks.?
The conditions that affect physical stability are heat, temperature, compression, pressure, and the molecular structure.
How does a marble rock break?
Marble rock breaks primarily through physical processes such as weathering and erosion, as well as through mechanical stress. Physical weathering can occur due to temperature fluctuations that cause expansion and contraction, leading to cracks. Additionally, marble can fracture under pressure or impact, particularly along its natural fissures or weaknesses. Chemical weathering, such as the reaction with acidic substances, can also weaken the structure and contribute to its breakdown.
What common substance can be found in all three physical stateses under various atmospheric conditions?
This substance is water.
What type of weathering affects the Aleutian islands?
Weathering is the gradual destruction of rock under surface conditions. The Aleutian Islands are part of the Pacific Ring of Fire and part of the Pacific Plate which has a high concentration of volcanoes.

What common mineral is resistant to both physical and chemical weathering?
Quartz is a common mineral that is resistant to both physical and chemical weathering. Its hardness and lack of cleavage make it more durable under mechanical forces, while its chemical composition is less reactive to chemical weathering processes.

What ore rock contains aluminum?
Bauxite is the primary ore rock that contains aluminum. It is formed from the weathering of aluminum-rich rocks under tropical conditions.
Will pyrite dissolve?
Pyrite will not dissolve in water or any type of simple acid. It is a very stable mineral and is resistant to weathering and dissolution under normal environmental conditions.
What chemical weathering process occurs when chemicals combine with water in a chemical reaction to change the physical properties of the rock?
Since igneous rocks form at high temperatures, and under pressure conditions ranging from one to several atmospheres. However, the conditions at the Earth's surface are somewhat different than the conditions at which most rocks and minerals form. Therefore, the materials are no longer at equilibrium when they are exposed to surface conditions. Under these conditions, there is a tendency for all ordered systems to seek lower levels of energy or order. This is all done through weathering. Weathering - the disintegration and decomposition of rock at or near the surface of the earth. It affects the rocks in place and no transport is involved. This distinguishes weathering from erosion.Mechanical/physical weathering - physical disintegration of a rock into smaller fragments, each with the same properties as the original. Occurs mainly by temperature and pressure changes.Chemical weathering - process by which the internal structure of a mineral is altered by the addition or removal of elements. Change in phase (mineral type) and composition are due to the action of chemical agents. Chemical weathering is dependent on available surface for reaction temperature and presence of chemically active fluids. Smaller particle sizes weather by chemical means more rapidly than large particles due to an increase of surface area. Look at the diagram below and you will see that as the particles get smaller, the total surface area available for chemical weathering increases.
What is a rule or principle describing a physical relationship that always works in the same way under the same conditions?
Law
What common substance can be found in all three physical stateses under various atmospheric conditions?
This substance is water.
Mechanical weathering or erosion is more rapid in what type of climate?
Mechanical weathering and erosion are generally more rapid in cold and wet climates. This is because the presence of water, which freezes and thaws, can increase the rate of physical breakdown of rocks. Additionally, cold temperatures can cause rocks to contract and expand more frequently, aiding in their breakdown.
