In the 1800s, westward expansion brought settlers and their livestock into direct contact with native predator and prey species. Much of the wolves’ prey base was destroyed as agriculture flourished. With the prey base removed, wolves began to prey on domestic stock, which resulted in humans eliminating wolves from most of their historical range. Predator control, including poisoning, was practiced here in the late 1800s and early 1900s. Other predators such as bears, cougars, and coyotes were also killed to protect livestock and “more desirable” wildlife species, such as deer and elk.
Population: 5,000 (San Pedro de Atacama) Altitude: 2,400 metres. Climate: Daytime highs in the Atacama Desert are around 20°C – 25°C and night-time temperatures are around 12°C. In winter (June to August), temperatures can drop to freezing or even below.
<span>The
causes of environmental problems in Sub-Saharan Africa are deforestation,
development, and increased population. As the country is aiming for development,
its environmental status is impaired. Increasing population resulted to
migration to higher urban or rural areas, and continuous land cultivation which
eventually caused deforestation and dilapidation.</span>
The answer is D. Exosphere
Exosphere is the outermost Layer of the Atmosphere that goes out about 500 - 10,000 Km in altitude.
It's the place where satellites and the space shuttle orbit the earth. Because it's difficult to define the boundary between exosphere and the outer space, exosphere may be considered as a part of outer space
The layer of the sun that radiates most of the light that reaches Earth is called the photosphere.
I hope this helps!
