b. geyser well.
c. spring well.
d. dry well.
Answer:
a
Explanation:
Answer:
Political system formation and establishment are crucial because they offer a framework for governing and arranging society. Political structures support the upkeep of law and order, the defense of individual rights, and the equitable allocation of resources. They create laws and institutions that permit dispute resolution through peaceful means and provide everyone a chance to take part in decision-making. In general, political institutions are essential for upholding stability, advancing justice, and ensuring a society's well-being.
a grassland with few trees
a cold region with tundra
a large evergreen forest
The one which best describe a steppe is a grassland with few trees Option(b) is correct. Steppe dry land with xerophilous vegetation found for the most part in locales of outrageous temperature reach and loess soil.
The Russian name for such woods is taiga, as steppe is the Russian word for meadows; and it is advantageous to utilize these terms to portray the two zones of vegetation that put forth limited lines on human existence.
Steppes are essential fields on dry territories, which are not appropriate for the foundation of trees in sloping districts, lower regions, and marshes Steppes are exceptionally assorted and mosaic-like territories described by perpetual graminoids of Bromus.
The Western Steppe was moderately immaculate by people until the seventeenth hundred years. Prior, the region was occupied by roaming clans that involved the land as field for homegrown steers and for hunting. The primary rural settlements were created by the Romans in the western piece of the steppe along waterway valleys of the Dniester.
Therefore Option(b) is correct.

Answer:
d. none of the above
Explanation:
The desert is a very frequent bioclimatic landscape on the earth's surface, characterized by its very low rainfall and low presence of fauna and flora, given the low humidity levels. Although the traditional image of the sandy desert refers to warm and equatorial climates, the truth is that they also count as deserts those located on the Arctic plateau or in the tundra.
The deserts are the product of different erosion processes, such as wind (given its high presence of winds that even form sandstorms) or the impact of solar radiation. The degree of intensity of these factors will depend on many desert characteristics, such as the type of sand formed or the nature of the soil.
Desert vegetation is, in principle, scarce, given the very low humidity margins. The one that exists has adapted to resist such adverse conditions, and it is usually xerophilous vegetation, with a predominance of spiny and resistant plants, such as the cactus, as well as weeds and, at best, small shrubs height.
Contrary to what is thought, there is a well-defined but very scarce desert ecosystem, although adapted to such an adverse environment and focused on the preservation of body moisture. Perhaps this is why reptiles (such as snakes), insects (ants, beetles) and arachnids (scorpions, spiders) abound.
Revealed by erosion and protected from moisture, in the deserts there are numerous mineral resources, such as oil basins (especially in the Middle East) or heavy metals.
Desert sand, also, is usually rich in calcareous elements and salts, so salt is often found in desert areas, such as in the Uyuni region of Bolivia. This type of desert drains the humidity of the environment even more, thus feeding back its aridity.
Answer:
Erosion has exposed limestone, shale and sandstone geology of the area in the scenic cliffs along the shore of Lewis and Clark Lake SRA, a reservoir on the Missouri River in Knox and Cedar counties.
Environmental science studies the interactions between the physical, chemical, and biological components of the environment, including their effects on all types of organisms. Earth science (also known as geoscience), is an inclusive term for all sciences related to Earth (geology, meteorology, oceanography, etc). Although environmental and earth science cover essentially the same material, environmental science places greater emphasis on the biological realm, while earth science places greater emphasis on the physical realm.
The four spheres are the geosphere (all the rock on Earth), hydrosphere (all the water on Earth), atmosphere (all the gases surrounding Earth), and biosphere (all the living things on Earth).
The spheres interact to effect Earth’s systems and processes, and they are constantly changing each other.
For example, ocean currents (hydrosphere) affect air temperature (atmosphere): The Gulf Stream is a powerful water current in the Atlantic Ocean. It’s warm water moderates the temperatures on the east coast of the USA.
Another example of how the spheres affect each other is through erosion. Erosion happens in the desert when wind (atmosphere) shapes the sand in the geosphere. Water (hydrosphere) can also shape land, such as in the formation of the Grand Canyon.
Explanation:
Lakes and wetlands also have distinctive biogeochemical characteristics with respect to their interaction with ground water. The chemistry of ground water and the direction and magnitude of exchange with surface water significantly affect the input of dissolved chemicals to lakes and wetlands. In general, if lakes and wetlands have little interaction with streams or with ground water, input of dissolved chemicals is mostly from precipitation; therefore, the input of chemicals is minimal. Lakes and wetlands that have a considerable amount of ground-water inflow generally have large inputs of dissolved chemicals. In cases where the input of dissolved nutrients such as phosphorus and nitrogen exceeds the output, primary production by algae and wetland plants is large. When this large amount of plant material dies, oxygen is used in the process of decomposition. In some cases the loss of oxygen from lake water can be large enough to kill fish and other aquatic organisms.
The magnitude of surface-water inflow and outflow also affects the retention of nutrients in wetlands. If lakes or wetlands have no stream outflow, retention of chemicals is high. The tendency to retain nutrients usually is less in wetlands that are flushed substantially by throughflow of surface water. In general, as surface-water inputs increase, wetlands vary from those that strongly retain nutrients to those that both import and export large amounts of nutrients. Furthermore, wetlands commonly have a significant role in altering the chemical form of dissolved constituents. For example, wetlands that have throughflow of surface water tend to retain the chemically oxidized forms and release the chemically reduced forms of metals and nutrients
