Most water, including drinking water, has a neutral pH that exists between 6.5 and 8.5, but acid rain has a pH level lower than this and ranges from 4–5 on average. [1] [2] The more acidic the acid rain is, the lower its pH is. [2] Acid rain can have harmful effects on plants, aquatic animals, and infrastructure.
Annually, the rain belt across the continent moves northward into Sub-Saharan Africa by August, then passes back southward into south-central Africa by March. [22] Areas with a savannah climate in Sub-Saharan Africa, such as Ghana, Burkina Faso, [23] [24] Darfur, [25] Eritrea, [26] Ethiopia, [27] and Botswana have a distinct rainy season. [28]
Sand and water on the side of the road, causing erosion on the environment Plastic bags dumped by the road side in Katete in mbarara district in western Uganda. The erosion caused by rains, rivers and winds as well as over-use of soils for agriculture and low use of manures have resulted in turning the soils infertile, as for example, in the plains of the Nile and the Orange River.
On average, Tutunendo has 280 days with rainfall per year. Over ⅔ of the rain (68%) falls during the night. The average relative humidity is 90% and the average temperature is 26.4 °C. [63] Quibdó, the capital of Chocó, receives the most rain in the world among cities with over 100,000 inhabitants: 9,000 millimetres (350 in) per year. [62]
Sulfuric acid rain in the atmosphere of Venus evaporates before reaching the ground due to the high heat near the surface. [2] Similarly, virgae happen on gas giant planets such as Jupiter. [citation needed] In September 2008, NASA's Phoenix lander discovered a snow variety of virga falling from Martian clouds. [3]
Over the years the Earth's eccentricity has varied between 0.005 and 0.0607, today the eccentricity of Earth's orbit is approximately 0.0167. [5] While the value of eccentricity does impact the distance of the Earth from the Sun, its primary impact on insolation comes from its modulating effect on the procession cycle.
Every so often we hear horrifying stories of modern day cannibalism. In 2012, a naked man attacked and ate the face of a homeless man in Miami.That same year, a Brazilian trio killed a woman and ...
Winrock International states, "In the humid tropics, the relative importance of acid soils is greatest in Latin America (81%), but also significant in Africa (56%) and Asia (38%)". [4] Traditionally on commercial farms, aluminum toxicity is countered by adding lime to the soil, which neutralizes the acid and renders the aluminum inert. However ...
