D or b you chose because it can go any way
Fossil fuels burn: cause
Glaciers melt: effect (mostly; the melting ice caps are a positive feedback loop of sorts)
Climates change: effect
Rain falls in unusual amounts: effect
Cities become more industrialized: cause
Human population grows worldwide: cause
The answer is D. centripetal force
This definition of centripetal force is a force acting towards the center of an object moving in a circular motion. Acceleration is the rate of which velocity changes over a period of time. If you pick a point on say a rotating circle and find the tangential velocity at each point it goes through, the acceleration would be towards the middle.
3 rd one because I had this on my test
