Which of the following is an accurate definition of biogeography? (1 point)

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 study of the purposeful clearing of a forested landscape of all, or selected, trees by humans

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

Thawing permafrost is leading to an increase in mammal populations.
Thawing permafrost leads to grasses and lichens pushing out shrub species.
Thawing permafrost leads to the creation of lakes and swamps where there were none.
Thawing permafrost leads to fewer beaver ponds.

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.**

This highlights a direct physical change in the landscape as permafrost melts, causing the ground to settle and water to collect, resulting in new aquatic features in the environment.

Thawing permafrost leads to fewer beaver ponds.

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.**

This statement emphasizes the physical transformation of the landscape due to the melting of permafrost, which impacts hydrology and can result in new bodies of water forming in areas previously occupied by frozen ground.

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

(1 point)
detecting a change in a person's study habits
detecting a change in regional forest cover
detecting a change in animal extinction rates
detecting a change in a backyard garden

The best use of satellite imagery from the list is: **detecting a change in regional forest cover.**

Satellite imagery is particularly effective for observing large-scale environmental changes, such as changes in forest cover, due to its ability to capture extensive areas over time.
