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:
Normal fault
Explanation:
Tensional stress occurs as a result of forces which could be wind, water etc pulling the rocks apart and forming faults. Faults are also known as a type of fracture which occurs between rocks.
Tensional stress along a fault can result in a dropped hanging-wall block relative to the footwall side(in a perpendicular position) thereby producing a normal fault.
Answer:
The probability of a Virgin America flight being delayed by a late-arriving aircraft is 1.73%. The probability of a Virgin America flight being delayed for any reason is 8.01% (as calculated in Question 1).
So if a Virgin America flight is delayed, the probability that it is because of a late-arriving aircraft is 1.73/8.01=21.6%
Explanation:
Answer:
Yes, that is very much true, just because climate change is caused mainly by changes in the balance between the amount of solar radiation received by Earth and the amount of heat radiated back into space by the Earth.
<em>"The change in stability of the environmental factors or the negative effects in the equilibrium inside the environment is called as the climate change."</em>
- <u>Global Warming And the green house effect:</u>
<em>"The overall rise in temperature of the earth spheres and its environment is termed as global warming, and its due the green house effect(the negative effect due to the increase level of CFC's)."</em>
- <u>The trapped Sun radiation inside the earth's sphere:</u>
<em>"Due to large number of CFC's inside the earths sphere, as they results in trapping the radiation which needs to be radiated back out of the earth's sphere. Causing the rise in temperature of the overall environment."</em>
Explanation:
- The chloro, floro and carbon elements which are also termed as the CFC's in general are created due increase level of industrial waste presence in the environment, leading to more solar radiation trapped inside the outer sphere of the earth's protective shield. Due, to this process the gasses are trapped inside the earth's sphere resulting in the rise in temperature.
- <u>Consequences of Climate Change:</u>
- As our earth passed from various levels and situations and as there were also some ice ages, which almost resulted in creating inhabitable situations for the living beings.
- But, these days earth is facing some alarming situations in the form of high temperature in its environment, which is some how leading to some thing more worse.
- There will be less resources of food in the near future and most importantly there will be species like polar bears and some marine animals who will face extinction due to the rise in temperature inside the environment.
Small fragments of orbiting bodies that have fallen on earths surface are known as "meteorites" and originate from larger bodies such as asteroids or comets in space. <span />
