A political map focuses on boundaries between entities, like countries, states or counties. They are generally brighter colors to easily distinguish the boundaries. Physical Maps: A physical map focuses on the geography of the area and will often have shaded relief to show the mountains and valleys.

Explain how humans have affected and been affected by the Danube river. Include it's physical geography, manmade changes, and th
Damm [24]

Answer: man activities such as agriculture, transport, energy production or urban development exert pressures on the water environment. When addressing pressures at the basin-wide scale, it has to be considered that cumulative effects may occur. Effects can occur both downstream pollutant  of a particular pressure. Addressing these issues effectively requires a basin-wide perspective and cooperation between countries.

Organic pollution refers to emissions of non-toxic organic substances that can be biologically decomposed by bacteria to a high extent. The key emitters of organic pollution are point sources like untreated or not sufficiently treated municipal wastewater from households, industries and major agricultural farms. The primary impact of organic pollution on the aquatic environment is dissolved oxygen depletion due to biochemical decomposition of organic matter. In the most severe cases this can lead to anaerobic conditions, to which only some specific organism can accommodate. The pollution with organic substances can therefore cause changes in the natural composition of the aquatic flora and fauna. It can also be associated with health hazards due to possible microbiological contamination of waters.

Nutrient pollution is caused by releases of nitrogen (N) and phosphorus (P) into the aquatic environment. Nutrient emissions can originate from both point and diffuse sources. Point sources of nutrient pollution are similar to those of the organic pollution. Diffuse pathways such as overland flow, urban runoff, soil erosion, tile drainage flow and groundwater flow can remarkably contribute to the emissions into surface waters transporting nutrients from agriculture, urban areas, atmosphere and even from naturally covered areas. Impacts on water status caused by nutrient pollution can be recognized through substantial changes in water ecosystems. In case of nutrient enrichment, water bodies can turn to eutrophic state where the growth of algae and/or macrophytes is substantially accelerated. Eutrophication severely impairs water quality and ecosystem functioning (e.g. oxygen depletion, toxicity, overpopulation of species) and might limit or even hinder human water uses as well (e.g. recreation, fisheries, drinking water supply).

Hazardous substances pollution involves contamination with priority substances and other specific pollutants with toxic effects on aquatic organisms and humans. Hazardous substances can be emitted from both point and diffuse sources. The most important sources of hazardous substances pollution are industrial facilities, agriculture (pesticide and contaminated sludge application), contaminated and mining sites, households and public buildings via municipal wastewater and urban run-off (deposited air pollutants, litter, combined sewer overflows). Moreover, significant volumes of deadly toxins can be unexpectedly flushed directly into watercourses by occasional industrial accidents or floods. Hazardous substances can pose serious threat to the aquatic environment. Depending on their concentration and the actual environmental conditions, they can cause acute (immediate) or chronic (latent) toxicity. Some of the hazardous substances are persistent, slowly degradable and can accumulate in the ecosystem.

Surface waters suffer significantly from hydromorphological alterations. Interruptions to river and habitat continuity, disconnection of adjacent wetland/floodplains, hydrological alterations and future infrastructure can hugely impact  water status and therefore will need to be addressed in future.

It is assumed that the effects of the floods that impacted the countries in the Danube River Basin in recent years were worsened due to deforestation, the destruction of natural floodplains and climate change. Preserving the natural habitats of the many species living in the basin is a constant struggle. The habitats of pelicans in the Danube Delta and sturgeon species are particularly under threat.

Major problems affecting aquatic ecosystems in the Danube River Basin

Excessive nutrient loads (particularly nitrogen and phosphorous)

High amounts of organic substances originating from untreated or poorly treated wastewater

Changes in river flow patterns (hydromorphological alterations) and its effect on sediment transportation

Contamination with hazardous substances (including heavy metals and organic micropollutants)

Accidental pollution from industrial and mining facilities

Degradation and loss of wetlands

Human pressures and impacts are investigated and addressed in the frame of the Danube River Basin Management Plan (according to the WFD).

What are four pieces of evidence for continental drift?
Alexus [3.1K]

Answer:

- Shape of the continents

- Fossils of the same species found on continents that are not connected

- Evidence of ice sheets in places that are hot in the present

- Mid-ocean ridges

Explanation:

The continental drift theory is a theory that suggests that the continents are always on the move, thus they change their shape, location, collide with each other, move away from each other etc.

The shape of South America and Africa is one of the evidences. If the shapes of the continents are taken out of a map, and the eastern coast of South America and western coast of Africa are merged, they fit in perfectly.

There are numerous fossils of the same species of animals and plants that have been found all over the world, even though the continents are isolated and separated by water bodies.

In some places that are very hot in the presence, like South Africa, have evidence of ice sheets. In the current conditions that is simply not possible considering that the temperature in this part of the world goes well over 40 C degrees.

The mid-ocean ridges are very nice proof of the continental drift theory. They are one of the evidence that can be observed in the present, where new crust is constantly forming and pilling up, while pushing the old crust sideways further away from it.
