Leaching
The process is called leaching. Rainwater percolates through the upper layers of soil, carrying dissolved substances like nutrients and minerals with it. These substances are then deposited in the lower layers of soil, enriching them with essential components for plant growth.
The removal of substances that can be dissolved from rock and soil due to water passing through is called leaching. This process can result in the transport of nutrients or contaminants depending on the substance being dissolved.
Leaching is the removal of substances by percolating water.The movement of dissolved substances or particles into a horizon is called illuviation. The movement of dissolved substances or particles out of a horizon is called eluviation.
Limestone is dissolved by carbonic acid through a process called chemical weathering. Carbonic acid forms when rainwater combines with carbon dioxide in the atmosphere or soil, creating a weak acid that gradually breaks down the calcium carbonate in limestone over time.
Rainwater can dissolve rocks that contain minerals such as limestone, chalk, and marble, which are mostly made of calcium carbonate. These rocks are easily weathered by the acidic properties of rainwater, leading to the process of dissolution. Over time, this can result in the formation of features like caves, sinkholes, and karst topography.

Rainwater can contain dissolved gases through a process called absorption. As rain falls through the atmosphere, it can absorb gases such as oxygen, nitrogen, and carbon dioxide. Additionally, interactions with organic matter and minerals in the environment can also contribute to the presence of dissolved gases in rainwater.
Precipitation causes dissolved substances to be left behind to form minerals after water in lakes or ponds evaporates.
The compound responsible for the acidity of rainwater and soil is sulfur dioxide (SO2) dissolved in water, which forms sulfuric acid (H2SO4). This process is known as acid rain.

Percolation, leaching, and chemical weathering.
The process is called filtration. It involves passing a mixture through a porous material, like filter paper or a filter membrane. The dissolved substances are trapped on the filter, while the solvent passes through.
When two substances mix to form a solution, heat is either evolved (an exothermic process) or absorbed (an endothermic process

Dolomite can be chemically weathered by rainwater through a process called carbonation. Rainwater, which is slightly acidic due to dissolved carbon dioxide, reacts with dolomite to form carbonic acid. This acid then reacts with the dolomite, dissolving it and releasing calcium and magnesium ions into the rainwater.
