They are brought from colder regions e.g. the North and South poles where ice caps are melting to give cold water. Currents are due to the effect of wind on the water.
Based on the Continental drift hypothesis, it is believed that<u> B. </u><u>Continents </u><u>may </u><u>collide </u><u>in the </u><u>future</u><u>.</u>
<h3>Continental Drift Hypothesis</h3>
- Posits that continents were once part of a super continent and then broke apart.
- Posits that continents will keep moving until they collide again to form another super continent after which they will then break apart.
The hypothesis therefore posits that continents will collide at some point millions of years into the future with one such example being the Americas and Asia.
