Rain water + atmospheric CO2 gives Carbonic Acid - very weak but over time able to dissolve limestone.
Lead sulfide is a black solution. It is insoluble in water and is a precipitate. The principle of the lead acetate test is the formation of lead sulfide.
As water flows through a limestone, some of the rock dissolves. This process can lead to the formation of cavities and caves. If a cave becomes too large and unstable to support the overbearing rock, it will collapse, leaving a sink hole at the surface.
Reflection and refraction.
The formation of a gas that escapes the system, the formation of a precipitate, or the formation of water can drive a double displacement reaction (metathesis reaction) to completion.
The statement is false as a generalization.
Interlacustrine means situated between lakes or bodies of water. This led to state formation in Africa because much of Africa is water-less. The water enabled people to band together and form communities.
Harold Urey and Stanley Miller were able to prove the hypothesis that conditions during the early portion of earth's formation were conducive to complex chemical reactions. These reactions formed amino acids, which are the bases of organic compounds that lead to life on earth.
Subduction zones lead to the formation of volcanic activity because the water combined with crust and mantle material lowers the rock's melting point temperature, causing the rock to melt and produce magma, which then creates volcanic activity.
Rain water + atmospheric CO2 gives Carbonic Acid - very weak but over time able to dissolve limestone.
Clouds form when water evaporates, travels up the atmosphere, cools and then condenses.
Like the formation of your face.
Heat and pressure lead to the formation of metamorphic rocks.
