Answer:
faults can cause sudden earthquakes when the tension of the tectonic plates build up and then releases
The dating technique which was used to establish the age of the volcanic ash at the Laetoli site is: potassium-argon (K/A) dating.
<h3>What is absolute dating?</h3>
Absolute dating can be defined as a radioactive process that is typically used to accurately determine the age of a rock, volcanic ash or fossil, by measuring the decay of the isotopes that is associated with the rock or within the fossils.
Thus, scientists can accurately determine the age of a volcanic ash, rock or fossil by measuring its isotope concentration such as through the use of potassium-argon (K/A) dating.

Answer:
we need tropical rain forests because they produce oxygen and clean the atmosphere to help us breathe. They also provide us with medicinal plants and may be the source to cure deadly diseases.
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.
