What happens to predator populations when their prey declines?

Back

Predator populations, such as foxes, may decrease when their prey, like rabbits, declines due to reduced food availability.

What is a divergent plate boundary?

Back

A divergent plate boundary is a tectonic boundary where two plates move away from each other, often resulting in the formation of new crust, such as mid-ocean ridges.

Front

What geological feature is formed at a divergent plate boundary?

Back

A mid-ocean ridge is formed at a divergent plate boundary due to the separation of tectonic plates.

Front

Why are ocean currents significant to coastal climates?

Back

Ocean currents are significant because they can influence air temperatures, affecting the climate of coastal regions.

Front

What is an invasive species?

Back

An invasive species is a nonnative organism that spreads rapidly in a new environment, often outcompeting native species for resources.

Front

What impact does clear-cutting have on biodiversity?

Back

Clear-cutting can lead to a significant loss of biodiversity by destroying habitats and reducing the variety of species in an area.

Front

What is the role of nutrients in ocean currents?

Back

Nutrients are brought to the surface by ocean currents, supporting marine life and ecosystems.

Front

How does kudzu affect local ecosystems?

Back

Kudzu can negatively impact local ecosystems by blocking sunlight to other plants, leading to their decline.

Front

What is the difference between clear-cutting and selective cutting?

Back

Clear-cutting involves removing all trees in an area, while selective cutting involves removing only certain trees, preserving the overall forest structure.
