What’s the difference between a landslide and an avalanche?

Landslides is a natural disaster that involves the breakup and downhill flow of rock, mud, water and anything caught in the path while avalanche is a large mass or body of snow and ice sliding swiftly down a mountain side, or falling down a precipice.

an adaptation is a change or process by which an organism takes to be better suited for its environment. for example; migration is a behavioral adaptation, this is needed because birds are not built to last extremely cold climates. there are different adaptations because there are different species needing to adjust to different things, bears don't migrate; they hibernate.
