Satellite imagery can be used to better understand certain changes on Earth. Identify the best use of satellite imagery from the list.(1 point)

The best use of satellite imagery from the list is **detecting a change in regional forest cover**. Satellite imagery is particularly effective for monitoring large-scale changes in land use, such as deforestation, afforestation, and changes in vegetation cover over time.

Question

Analyze which statement best captures how thawing permafrost changes Earth’s physical geography.(1 point)
Responses

Thawing permafrost leads to the creation of lakes and swamps where there were none.
Thawing permafrost leads to the creation of lakes and swamps where there were none.

Thawing permafrost leads to fewer beaver ponds.
Thawing permafrost leads to fewer beaver ponds.

Thawing permafrost is leading to an increase in mammal populations.
Thawing permafrost is leading to an increase in mammal populations.

Thawing permafrost leads to grasses and lichens pushing out shrub species.

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.** As permafrost thaws, the ground becomes unstable and can create depressions that fill with water, forming new aquatic ecosystems.

Question

How has thawing permafrost affected the people who live in areas where permafrost occurs?(1 point)
Responses

With fewer beaver ponds, people are finding it difficult to capture beavers for human uses.

More ice cellars are able to be built because of thawing permafrost.
More ice cellars are able to be built because of thawing permafrost.

Entire villages are being forced to relocate 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

The statement that best reflects 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 destabilize structures and disrupt the living conditions for communities, leading to the need for relocation.

Question

Which statement best analyzes the impact of the Burmese python on the Florida Everglades region?(1 point)
Responses

The growth of the Burmese python population has resulted in a severe decline in the reproductive success of turtles.
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 Florida Everglades region because it is easy to detect and remove.
The Burmese python, though an invasive species, has not had a great impact on the Florida Everglades region because it is easy to detect and remove.

The Burmese python has caused minimal ecological change in the Florida Everglades region because its food preference is not dominant in the Everglades.
The Burmese python has caused minimal ecological change in the Florida Everglades region because its food preference is not dominant in the Everglades.

The growth of the Burmese python population has resulted in severe declines in native mammal species.

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 of Burmese pythons has had a significant negative impact on the native wildlife, particularly among small to medium-sized mammals, as they are heavily predated upon by these invasive snakes.
