What are two examples for chemical weathering?

CARBONATION process by which dissolved carbon dioxide in rainwater or moisture in surrounding air forms carbonic acid and reacts with the minerals in the rock. This process weakens the rock thus breaking it down in the process.e.g.: Calcium Carbonate + Water + Carbon Dioxide --->Calcium Carbonate (soluble)HYDROLYSISchemical reaction between the minerals in the rock and hydrogen in rain water. For example, during hydrolysis, the feldspar in granite changes to claymineral which crumbles easily, weakening the rock and causing it to break down.OXIDATION The process by which oxygen combine with water and minerals in the rock such as calcium and magnesium. When iron reacts with oxygen, reddish -brown iron oxide is formed. The iron-oxide crust crumbles easily and weakens the rock.e.g. : Iron + Oxygen --> Iron Oxide (crumbles)SOLUTIONprocess by which minerals in the rocks dissolve directly in water.HYDRATION process where minerals in the rock absorb water and expand, creating stress which causes the disintegration of rocks.


Which process describes how different minerals form at different rates?

Fractional Crystallization


What is quartz fluorescence?

Fluorescence occurs when a substance has absorbed light and later emits that light. Quartz is a material that undergoes this process. Minerals and creatures can both exhibit fluorescence.


What is it called when clay turns to ceramic?

I believe the process is called firing, some clays require temperatures of close to 2500 degrees F, other clays it takes much less heat depending on the minerals in the clay.


How is partial melting related to fractional crystallization?

Partial melting occurs in rocks because the different minerals that compose rocks have different melting points. For example, felsic minerals (e.g. quartz and feldspar) melt at around 700 degrees Celsius while mafic minerals (e.g. pyroxene and olivine) melt at around 1200 degrees Celsius. Therefore, felsic minerals will melt first leaving the mafic minerals solid.Fractional crystallization occurs when minerals from a magma cool and crystallize out of the magma. The first crystals to melt in partial melting will be the first minerals to crystallize out when the magma begins to cool. Therefore, mafic minerals will crystallize first, followed by felsic minerals.Both partial melting and fractional crystallisation tend to produce a more felsic magma than their source rocks.The difference is simply that they are the reverse of one another, heat it up, cool it down. Things that melt first solidify last and separate from one another.

What is seeping downward through the horizons dissolves and carries minerals into lower horizons by the process of?

Leaching is the process in which water seeping downward through the soil dissolves and carries minerals from the upper horizons into lower horizons. This movement of minerals can impact the soil fertility and nutrient availability in different layers of the soil profile.

What is the name of the process by which water carries materials from the upper horizons down on the lower levels?

The process you are referring to is called leaching. Leaching occurs when water transports minerals, nutrients, and other materials from the upper soil horizons down to the lower levels, which can affect soil fertility and the composition of different soil layers.


What is the process by which soluble minerals are dissolved and removed from soil?

The process by which soluble minerals are dissolved and removed from soil is called leaching. It occurs when water passing through the soil carries minerals with it, leading to the loss of nutrients from the soil. Leaching is influenced by factors such as precipitation, soil composition, and land use practices.


Is cementation the process of which dissolved minerals cristalize and glue sediments together?

Yes, cementation is the process by which dissolved minerals crystallize and bind sediment grains together into a solid rock. This process occurs in sedimentary rocks and helps in their consolidation.


What is the process called that carries dissolved materials downward in soil?

The process is called leaching, where water carries dissolved materials downward through the soil profile. This can lead to nutrients being lost from the topsoil and potentially causing groundwater contamination.
