They are the only mammals capable of self-powered flight, but they’re by no means rare. Bats account for about one in five of all mammals living on the planet and there are around 1,300 bat species worldwide. They are, however, threatened by loss of natural habitat and hunting, and many species of bat are considered endangered or threatened.
Though they’re the only mammals to have developed the ability to fly, they’re extremely good at it. The Mexican free-tailed bat can achieve speeds up to 99 miles per hour in the air and fly as high as 10,000 feet, as high as a bald eagle.
They’re the only flying mammals and are extremely diverse
Answer:
A. the concept of cultural landscape
Explanation:
The adobe is a structure that was made by three tribes (Zuni, Pueblo, and Hopi) that lived in Southwest of America. The adobe is built with sun-dried earth made from sand to make strong brick-like materials, clay, water, sandstone mixture, and organic matter. Gaps were filled with much more mud between the blocks to prevent the wind, rain, and keep out bugs and other unwanted pests. The Adobe building is an example of a cultural landscape.
Answer:
Karst topography is formed from soluble rocks with many features that create crevices that channel or funnel the surface water into the ground and aquifers below. This can lead to contamination of the water quality in aquifers.
Explanation:
Karst topography refers to the topography formed from soluble rocks such as limestone, dolomite, and gypsum. The topography evolves as the soluble rocks are exposed to wind, sun, and precipitation that erodes the rock materials and creates crevices and the groundwater is channeled away from the surface, inhibiting the formation of lakes and reserves of water at the surface. When these sorts of rocks begin to dissolve caves and crevices and other forms of underground drainage. Five topographic features a geologist might find are solutions flutes and limestone pavement, cenotes, funnel-shaped sinkholes, and reappearing streams.
The surface hazards associated with karst topography are sinkholes as well as other topographic hazards such as subsidence and slope movements. There is a lot of surface water and groundwater interaction in a landscape with karst typography and so aquifers are susceptible to contamination from pollution and the use of fertilizers and chemicals at a higher rate than other topographies. Urban areas and areas where there is a lot of animal husbandry are especially vulnerable to aquifer contamination.
Answer: Metal Detectors
Explanation: Metal detectors are inexpensive and easy to use equipment used to discover relics of the past. While it is useful in archaeology as a tool that discovers objects from the past quite easily, it is also a threat to archaeology. Some hobbyists and looters who come across archaeological finds which may be important to understanding past civilizations or a different era do not report these finds. Even worse, some looters knowingly infringe on archaeological sites and are aided by the metal detectors.
Was that while much of Egypt is desert, the fertile Nile River Valley provided the ancient Egyptians. With the means to sustain life. So, in addition to river systems and land quality, other natural resources. Such as iron ore, copper, and gold. Had affected where civilizations developed.
