All atmospheric circulation systems are summarized under the term “planetary circulation” (also called general, planetary or global circulation). The weather dynamics in the earth’s atmosphere are determined by their interaction.
Plants that have leaves all year round and don’t shed their foliage in winter are called evergreens. Among the most common evergreens are many conifers.
To classify different soils, a distinction is made between soil types such as brown soil, podzol, gley, etc. The soil types are systematically classified with diagnostic features and properties. The characteristic horizons and horizon sequences play a major role for the classification.
Soil conditioners are soil-improving soil additives that can increase soil fertility and soil life. Due to their low nutrient content, soil additives are not considered fertilizers.
Succulents are plants with a high-water storage capacity. Because of this trait, the plants are well adapted to drier climates. One of the best-known succulents are cacti.
Microorganisms, also called microbes, are microscopic creatures that cannot be seen with the naked eye. These include, for example, bacteria, microalgae and many fungi.
Greenhouse gases reflect sunlight bouncing off the Earth, acting like greenhouse glass. Air pollutants that affect the climate include carbon dioxide (CO2), which is produced when fossil fuels are used, methane (CH4), nitrous oxide (N2O) and fluorinated gases (F-gases).
Due to the filter function of the soil, even very small dirt or pollutant particles can be bound in seeping water. This prevents contamination of the groundwater.
The troposphere is the layer of the earth’s atmosphere closest to the ground. Most of the weather occurs in this layer.
Oxidation is a chemical reaction in which a substance emits electrons. Another substance absorbs the electrons and is reduced in the process. Oxidation is thus a partial reaction of a redox reaction (a chemical reaction in which one reactant transfers electrons to the other).
Soil formation is very different depending on the location. As a result, soils do not have a uniform structure, but are divided into layers that are more or less parallel to the surface. These layers, which differ in their properties, are called “soil horizons”. In general, the rock layer is at the very bottom, the
In an inversion weather situation, the temperatures do not decrease as usual, but increase. Due to this phenomenon, no exchange can take place between the upper and lower air layers and a barrier layer is created. Exhaust gases and dust particles collect under this and contribute to increased air pollution.
Humidity indicates the proportion of water vapour in a gas mixture. Since gases cannot absorb an unlimited amount of water, the relative humidity, on the other hand, describes the actual water content in relation to the physical maximum of a gas mixture.
Mapping means the graphic representation of objects and facts of the earth’s surface on maps or in plans.
