Why are some silicate minerals more easily weathered than others?

Because of their chemical composition, feldspars are more easily attacked by mildly acidic rainwater than say a quartz would be.

What minerals can be used to block light?
Most minerals are opaque, some more than others. Granite is very opaque.
What minerals are in scoria?
Feldspar, quartz, pyroxene, mica, magnetite among others.
Why are some minerals easier to identify than others?
Minerals vary in ways they can be distinduished. Some are easy to identify by hardness, color , streak, or luster
How do water and air help cause chemical weathering?
When minerals come into contact with air and water, some dissolve and others react and change into different minerals.
What 2 minerals are found in fine strands thin sheet's and irregular masses?
Muscovite and Phlogopite, along with Biotite and Lepidolite and many others are all minerals that cleave into thin sheets with a fair amount of flexibility. However, these minerals are all part of the silicate mineral group known as Micas. Slate can also be cleaved into thin sheets which are slightly flexible, but which are quite brittle. Graphite may also be expanded by chemical treatments to yield a flexible sheet known as graphite foil with interesting electrical and thermal properties.
Where are the silicale mineral forms?
Most silicate minerals form from molten rock as it cools. Still other silicates form from weathered silicates at Earth's surface, while others form under extreme pressure from mountain building.
What kind of minerals does not go with quartz feldspar fluorite or hornblende?
Fluorite does not go with the others. It belongs to Halide minerals, while the others (quartz, feldspar, and hornblende) belong to Silicate family of minerals.
Are asteroids made of iron and nickel?
Some asteroids are. Most are composed of a mixture of silicate minerals. Others are a mixture of the two.
Why are rocks made of the same basic minerals?
Certain minerals are harder than others, which means that they are more easily traceable (as they have not been broken down to the extent that they are no longer visible). Quartz is both incredibly hard and common. Silicate minerals are very hard in general, making them the most common minerals. This is also related to the fact that Silicon is the most abundant element in the Crust, or indeed the whole Earth. For this reason, most minerals present in rocks are similar.
Which silicate minerals are the main components of most rocks on earth's surface?
oxygen and aluminum
Why are some rocks is easily broken?
Some rocks are easily broken due to the weak bonds between the molecules in them. For instance, muscovite is easily torn because of the weak bond between the fourth silica in the silicate tetrahedron. There are strong bonds between some molecules and weak bonds between others. The breaks occur along the weak bonds.
What makes curtin minerals stronger than others?
Certain minerals are stronger than others because of the way their atomic structures are arranged.
What minerals do Maryland's soil contain?
Nitrogen, phosphorus and potassium in abundance and others as trace minerals.

95%. All others are referred to as rare minerals.
