Answer:A) The continents move.
B) The continents drifted apart over a long period.
C) The continents were once connected as one landmass.
Explanation:
Continental drift is the theory that continents were once ONE huge landmass and each continent shifted relative to other continents over many years. In 1912, Alfred Wegener named the single landmass Pangea.
According to Wegener, Pangea split about 200 million years ago, giving way to the oceans currently separating the continents. Prior to 1912, some scientists such as Roberto Mantovani had attribute the separation of the continents to volcanic activity, but this has since been proven to be wrong.
The ground-level ozone is a harmful air pollutant that can be a danger to one's health. It is commonly created by chemical between oxides and nitrogen. Similar to ground-level ozone, smog can also be a danger to one's health, especially to the lungs. It is a mixed smoke and fog.
The rate of natural increase refers to the difference between the number of live births and the number of deaths occurring in a year, divided by the mid-year population of that year, multiplied by a factor (usually 1,000). It is equal to the difference between the crude birth rate and the crude death rate.
