the graph shows how the distance an object traveled changed over time.

between which two points was the object traveling at the greatest speed?

a. between points a and b because that segment is horizontal.

b. between points b and c because that slope is the steepest.

c. between points c and d because that segment is the longest.

d. between points c and d because that slope is the steepest.

b. From b to c is the fastest because it is the steepest.

answer: land bridge theory. land bridge theory held that shifting portions of dry land explained the finding of identical species on different continents. plate tectonic theory eventually eliminated the land bridge theory.

some of your causes might be acidic rain or natural wildfires that cause the parks to be degraded
