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:
From a state of endangerment, many languages become extinct. When the speakers of a language are exterminated as what happened to Tasmanians in the 19th century, several languages suddenly died. Another reason for the extinction is the pressure exerted on a community to incorporate with a more powerful or larger group.
I believe it is a landform.
Answer:
South America and Africa
Explanation:
This is because of the equators position on the earth. If you look at a map with a equator, "An imaginary line drawn around the earth equally distant from both poles, dividing the earth into northern and southern hemispheres and constituting the parallel of latitude 0°," said Oxford Dictionaries, then you will see it pass right through South America and Africa. It passes through Indonesia and its minor islands, but that is an exception.
