Under most weathering conditions which mineral in granites and rhyolites would be most resistant to decomposition?
Quartz, by a long shot. Then orthoclase, muscovite, biotite, in that order
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.
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.
What common substance can be found in all three physical stateses under various atmospheric conditions?
This substance is water.
Substance that cannot be changed into a simpler substance under normal laboratory conditions?
Substance that cannot be changed into a simpler substance under normal laboratory conditions are elements. A physical blend of two or more substances that are not chemically combined is a mixture.

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.
Mechanical weathering or erosion is more rapid in what type of climate?
There are many types of mechanical weathering, some due to climatic conditions, some not. Excluding non-climatic causes, mechanical weathering such as plant root growth, would be assisted by tropical conditions which encourage plant growth and root hydraulics. In desert regions, weathering is more rapid under conditions of high wind, which causes abrasion of rock surfaces. In areas that experience hot/cold alternating temperatures, frost wedging and thermal stress will contribute to rapid mechanical weathering. The type of rock being exposed to agents of mechanical weathering would also play a part in the speed at which the weathering takes place, as some rock varieties are more easily mechanically weathered than others.

Grass tetany
