Explanation:
A number of African countries depend on extractive resources for revenues and export earnings but mining faces huge challenges related to environmental degradation and social issues. ... Mining has often been associated with deforestation, land degradation, air pollution, and disruption of the ecosystem.
In most classification schemes, which principal indicator is used to
delineate five zones and their subtypes?
Cloudiness
Temperature
Daylength
Precipitation
Vegetation types
Answer:
Vegetation types
Explanation:
In the case of biomes, which are perhaps the most commonly used classification scheme in physical geography, vegetation is the principal indicator to delinate the different zones and their subtypes.
Even if both vegetation and fauna define a biome, and a sub-biome, because vegetation is more pervasive than fauna, it becomes the principal indicator in practice.
The correct answer is E. Vegetation types
Explanation:
In geography, the zones around the world are classified into five main types: the tropical zone, the Arctic, the Antarctic, the South temperate zone, and the North temperate zone. These zones are determined by two main factors, the first one is the latitude, for example, the tropical zone is near the equator line, and the second one is the vegetation that is different in each zone. For example, the Arctic and Antarctic zones differ from others because the vegetation is not abundant and includes mainly grasses and mosses; on the opposite, in the tropical zone, the vegetation is abundant including diverse grasses, shrubs, and trees. At the same time, it is vegetation the key to determining sub-type zones. Thus, one principal indicator used to delineate the five zones is vegetation types.
Chinese cities will be submerged underwater
Answer:
You have posted a statement and not a question
Explanation:
Explanation:
China produces more carbon dioxide emissions than any other country, and its coastal cities will be dramatically affected by rising seas as the atmosphere warms, according to a November report by Climate Central, a nonprofit organization.
Barring large amounts of spending on shoreline barriers and flood control systems, these images show what China would face if carbon emissions cause global temperatures to rise by 2° Celsius (3.6°F), the current international target by 2100, or by 4° Celsius (7.2°F), roughly the warming predicted if no action is taken to curb emissions.
Shanghai
China's largest city, with a population of around 24 million at the edge of the East China Sea, has the most to lose from rising sea levels. Climate Central estimates that 76 percent of the Shanghai region's current population lives in areas that would eventually be underwater if the Earth warms by 4°C by 2100.

Tianjin
Tianjin has a lower elevation than its larger neighbor Beijing, and the city proper is home to about 11 million people. The rising waters created by a 4°C temperature increase would submerge about 29 percent of the area’s current population.

Shantou
The large southern port city of Shantou sits on a river delta surrounded by mountains, making it vulnerable to the encroaching ocean. Fifty-four percent of the current population lives below where sea level would end up following a 4°C warming scenario, in contrast to 22 percent for a 2°C increase.

Note: Because the elevation data used to model inundation tends to over-estimate the height of urban areas, rising seas would likely cover more than is shown on the map. Because of the difficulty of estimating how quickly ice will melt, the scenarios shown could develop over the course of several centuries.

What do we call the form of weathering that involves temperatures fluctuating around 0°C and is the dominant mechanical weathering process on coastlines?
Answer:
Freeeze-thaw weathering
Explanation:
Freeze- thaw weathering involves the breakdown of rock particles into smaller fragments through continuous fluctuations in the temperature of the water bodies. This form of weathering is common along coastlines. The water enters the rocks and then freezes when there is a decrease in temperature. The freezing expands the rock particles and aids frictions between the rock parts. This helps in the breakdown of the rocks to smaller particles.
It involves temperatures fluctuating around 0°C and is the dominant mechanical weathering process on coastlines
