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

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.


Do all silicate minerals contain iron?

silicon, oxygen, iron and magnesium


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 some rocks easily weathered than other rocks?

Some rocks are more easily weathered than others due to differences in mineral composition and structure. Rocks with weaker minerals or more porous structures are more susceptible to erosion from water, wind, and other environmental factors. Additionally, exposure to acid rain and high temperatures can also contribute to faster weathering of certain rocks.


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.


What is the most abundant mineral group in earths crust?

silicates


Do the minerals that make up a rock determine how fast it weathers?

Yes, the minerals that make upa rock partially determine how fast it weathers. But while there is some truth in this statement, the answer has to be false because the environment the rock surface is exposed to also determines how fast it weathers.


Which silicate minerals are the main components of most rocks on earth's surface?

oxygen and aluminum


What mineral group does silicon and oxygen elements form?

Silicon and oxygen elements form the mineral group known as silicates. Silicate minerals are the most common group of minerals on Earth's crust and are composed of silicon and oxygen atoms in combination with other elements like aluminum, iron, magnesium, and others.


What makes curtin minerals stronger than others?

Certain minerals are stronger than others because of the way their atomic structures are arranged.


What property can be used only for a few minerals?

Magnetism is a property that can be used for only a few minerals. Some minerals exhibit magnetic properties, while others do not. This property can be helpful in identifying and distinguishing certain minerals from others.
