Satellite imagery can be used to better understand certain changes on Earth. Identify the best use of satellite imagery from the list.
detecting a change in a backyard garden
detecting a change in a person’s study habits
detecting a change in animal extinction rates
detecting a change in regional forest cover
The accurate definition of biogeography is: "The study of the geographic distribution of living organisms and the characteristics of the environments in which they live." Biogeography focuses on understanding how and why species are distributed across different geographic areas and the factors influencing their distribution patterns.
The statement that best captures how thawing permafrost changes Earth's physical geography is: "Thawing permafrost leads to the creation of lakes and swamps where there were none." Thawing permafrost causes the previously frozen soil to become waterlogged and unstable, resulting in the formation of lakes and swamps. This process is known as thermokarst, and it is a significant consequence of permafrost thawing. This change in Earth's physical geography can have various impacts on ecosystems, hydrology, and the overall landscape. The other statements do not specifically address the physical changes caused by thawing permafrost.
The statement that best captures how thawing permafrost has affected the people who live in areas where permafrost occurs is: "Entire villages are being forced to relocate because of thawing permafrost." Thawing permafrost can lead to land instability, erosion, and increased flooding in these areas. This can result in infrastructure damage, including buildings and roads, making it necessary for entire communities to relocate to safer areas. The other statements do not accurately reflect the impacts thawing permafrost has on the people living in these regions.
The statement that best analyzes the impact of the Burmese python on the Florida Everglades region is: "The growth of the Burmese python population has resulted in severe declines in native mammal species." The introduction and proliferation of the invasive Burmese python in the Florida Everglades has caused significant negative impacts on the native mammal populations. The pythons prey on a wide range of mammal species, leading to dramatic declines in their numbers, disrupting the natural balance of the ecosystem. This is a well-documented and concerning consequence of the python's presence in the region. The other statements either downplay or underestimate the ecological impact of the Burmese python in the Everglades.
The best use of satellite imagery from the list is detecting a change in regional forest cover. Satellite imagery can provide extensive coverage and high-resolution images of large areas, making it useful for monitoring and assessing changes in forest cover over time. This information can be crucial for conservation efforts and understanding the impact of deforestation on the environment.
Which of the following is an accurate definition of biogeography?
the study of the purposeful clearing of a forested landscape of all, or selected, trees by humans
he study of changing climate
the study of the geographic distribution of living organisms and the characteristics of the environments in which they live
the number of various living species that exist in a certain area
Analyze which statement best captures how thawing permafrost changes Earth’s physical geography.
Thawing permafrost leads to the creation of lakes and swamps where there were none.
Thawing permafrost leads to grasses and lichens pushing out shrub species.
Thawing permafrost is leading to an increase in mammal populations.
Thawing permafrost leads to fewer beaver ponds.
How has thawing permafrost affected the people who live in areas where permafrost occurs?
More ice cellars are able to be built because of thawing permafrost.
Entire villages are being forced to relocate because of thawing permafrost.
People are finding it easier to hunt on thawing permafrost.
With fewer beaver ponds, people are finding it difficult to capture beavers for human uses.
Which statement best analyzes the impact of the Burmese python on the Florida Everglades region?
The growth of the Burmese python population has resulted in a severe decline in the reproductive success of turtles.
The Burmese python, though an invasive species, has not had a great impact on the
The growth of the Burmese python population has resulted in severe declines in native mammal species.
The Burmese python has caused minimal ecological change in the Florida Everglades region because its food preference is not dominant in the Everglades.
