All Flashcards
What is clearcutting?
Logging method where an entire area of trees is removed at once.
Define selective logging.
Only certain trees are removed, leaving the rest of the forest intact.
Define group cutting.
Small groups of trees are removed, allowing the forest to regenerate more quickly.
What is habitat destruction?
Loss of homes and food sources for wildlife due to environmental changes.
What is soil erosion?
The washing away of soil due to lack of tree roots, leading to landslides and degraded ecosystems.
Define carbon sequestration.
The process of capturing and storing atmospheric carbon dioxide.
What is clearcutting?
Logging method where all trees in an area are removed at once.
Define selective logging.
Logging method where only certain trees are removed, leaving the rest of the forest intact.
Define group cutting.
Logging method where small groups of trees are removed, allowing for quicker forest regeneration.
What is habitat destruction?
The process by which a natural habitat becomes incapable of supporting its native species.
What is soil erosion?
The process by which soil is worn away and removed by wind or water.
What is carbon sequestration?
The process of capturing and storing atmospheric carbon dioxide.
What is the carbon cycle?
The biogeochemical cycle by which carbon is exchanged among the biosphere, pedosphere, geosphere, hydrosphere, and atmosphere of the Earth.
Define deforestation.
The clearing of forests for other land uses.
What are greenhouse gases?
Gases that trap heat in the atmosphere, contributing to global warming.
Define biodiversity.
The variety of life in the world or in a particular habitat or ecosystem.
What are the effects of clearcutting on local water quality?
Increased soil erosion leads to sedimentation and pollution of waterways, harming aquatic ecosystems.
How does deforestation contribute to increased greenhouse gases?
Deforestation releases stored carbon into the atmosphere as CO2, increasing greenhouse gas concentrations.
What is the impact of habitat destruction on wildlife populations?
Habitat destruction leads to loss of food sources, shelter, and breeding grounds, causing population declines and potential extinctions.
What is the effect of clearcutting on soil stability?
Removal of tree roots leads to increased soil erosion and decreased soil stability, increasing the risk of landslides.
