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:
Reflection
Explanation:
Think of it as reflection in a mirror. I hope that makes it easier to remember.
What are you asking, for the def??
Explanation:
Catastrophism is the theory that the Earth has largely been shaped by sudden, short-lived, violent events, possibly worldwide in scope, this contrast with Uniformitarianism that suggests that the landscape developed over long periods of time through a variety of slow geologic and geomorphic processes.
To meaningfully study the past, we must assume the same or similar mechanisms operated then as now, following this idea we conclude that uniformitarianism is a more logical theory, <em>geologists then consider periodic catastrophe (volcanic eruptions, earthquakes, meteorite impacts, and storm deposits) is one of those processes uniformitarianism suggests.</em>
