Soils are essential for the continuity of life on earth since many ecosystems depend on them for survival. Still, soils persist to face serious threats in so many ways. Soil erosion, use of chemical pesticides and herbicides, unsustainable agricultural practices, excessive farming, water pollution and land pollution are some of the aspects upsetting the natural …

Soil erosion is a process that involves the wearing away of the topsoil. The process involves the loosening of the soil particles, blowing or washing away of the soil particles, and either ends up in the valley and faraway lands or washed away to the oceans by rivers and streams.

The nitrogen cycle explains the how nitrogen flows between animals, bacteria, plants, the atmosphere, and the soil on earth. The uniqueness of the nitrogen cycle is that nitrogen is the most abundant gas in the earth’s atmosphere, about 78% of all air, but it can’t be directly utilized by the animals and plants unless it …

The water cycle explains the continuous movement of water on, above, and below the surface of the earth. It is also referred to as the Hydrological Cycle. The cycle describes the properties of water that make it undergo the various movements on the planet. The water cycle has nine main physical processes that create a …

Air pollutants are substances in the air which pose adverse risks to human health and have the potential of damaging the ecosystem. The substances are in the form of gases, liquid droplets, or solid particles and are either naturally occurring or anthropogenic.

Acid rain influences soil chemistry, plant activities, and the acidity of surface waters in general. In this sense, it means acid rain has many implications to the environment. The increase of acid rain is persistently affecting the health of humans and plants, the chemical composition of the soil, and most importantly the survival of aquatic …

Acid rain is formed by elevated levels of sulfur and nitric acids in the atmospheres that accumulate as a result of Nitrogen oxides (NOx) and Sulfur dioxides (SO2) emissions. Acid rain is a mix of atmospheric water molecules and dry depositions of Sulfur dioxides and Nitrogen oxides emitted from industries and vehicles. When these gases …
