What are some ways that humans modify their environments to suit the needs of their societies?

Humans commonly modify their environments by constructing roads, bridges, highways, and other structures for transportation. They can create parks, lakes, recreational areas, beaches, and other water areas. Humans construct houses, offices, skyscrapers, shopping centers, and other buildings to live and work in. Finally, they build hospitals, police stations, schools, fire stations, and other buildings for government services.

heat from the core of the earth causes convection currents to occur in the mantle. these currents slowly move the crust around.
