Answer:
prohibits the introduction of invasive species
controls the kind of waste and pollutants allowed
assesses human influence on the environment
designates protected zones on the continent
Explanation:
These four key terms are some of what the Madrid Protocol includes.
Prohibiting the introduction of invasive species keeps the ecosystem from being dominated and/or destroyed by a single species that the ecosystem is not built to handle.
Controlling the kind of waste and pollutants allowed on the continent ensures that the environment remains stable without the influence of outside chemicals, such as oil or carbon emissions that could harm the ecosystems.
Assessing human influence on the environment keeps track who does what and how they do it, essentially preventing extreme human action from being taken so as to preserve Antarctica's natural order.
Designating protected zones on the continent that can only be accessed with special permits ensures that only people who require access for research or whatnot, or more simply, qualified personnel, are able to enter these zones, so as to keep contact down to a minimum and further preserve Antarctica's natural environment.
Answer:
B) Distinctly alkaline diagnostic horizons, thin profiles, lack of organic material, and dominance of sandy materials are features most closely associated with aridisols.
Explanation:
The aridisols are types of soils that are found predominantly in arid areas. They are soils that are not considered as fertile, and are near the bottom by quality of soils. These soils are lacking organic material, and also are very exposed to erosion, with the primary reason being the climate, as it doesn't allow for lot of vegetation to grow. The horizons of the aridisols are distinctly alkaline diagnostic ones, with the profiles being very thin and labile. The top layer of the soil is dominated by sandy material, which is a result of the extensive weathering and erosion in their surroundings, so the wind is mostly transporting small sandy grains and covers most of the area with them.
When the value of a country’s currency falls, the currency is depreciating, so one unit of that currency can buy fewer units of other currency.
A depreciation of a country's currency makes its export goods cheaper for foreigners and domestic residents find that foreign imports are more expensive.
Answer:
They all travel the same speed.
Explanation:
In the vacuum region , all the light or waves , travels at the same speed , i.e. , at 299,792 kilometers per second , due to the free space available without any obstruction or hindrance .
Being it to be X - rays , Visible light , Infrared light , all travel at the same speed ,
Hence , the correct answer to the statement given in question would be , They all travel the same speed .
