Answer:

potassium-argon dating

Explanation:

Potassium-argon (K-Ar) dating technique is the most appropriate dating method for establishing the age of a volcanic ash. It is most applicable for dating minerals and rocks more than 100,000 years old.  It is based on measuring the product of the radioactive decay of an isotope of potassium (k) into argon (Ar). Since potassium is a common element found in many volcanic ash layer, the time since re-crystallization is calculated by measuring the ratio of the amount of argon 40 (Ar-40) accumulated to the amount of potassium 40 (K-40) remaining in these volcanic ashes.

Why is it better to have air conditioning units closer to the ceiling when living in Florida?
torisob [31]
It's better to have air conditioning units near the ceiling regardless of where you live. Since cool air sinks, air conditioning units are usually near the ceiling so the cool air can spread around the room more. Hope this helped =)

What is the relationship between the soil’s permeability and the amount of groundwater?
dexar [7]

Answer with Explanation:

The amount of groundwater that can be stored will largely depend on the <em>"soil's permeability." </em>A permeable soil means that <u>it is easy for water to pass through the pores.</u> It has<em> </em><em>larger pores that are well-connected to each other</em> thereby allowing water to flow freely. This also allows the water to pass through the rocks, which then <u>increases its </u><u>porosity</u>. This also leads to an easier way to extract the groundwater.

Consider the following observations. Classify each observation based on whether it is a real observation (a true statement of so
damaskus [11]

Answer:

The real observations are:

Moon rises in east, sets in west each day.

stars circle daily around north or south celestial pole

Positions of nearby stars shift slightly back and forth each year.

A distance galaxy rises in east, sets in west each day.

We sometimes see a crescent Jupiter.

Explanation:

Mercury it can seen from the Earth but no it phases.

Moon is seen in all parts of the Earth, the only difference is that in north pole the stars moves parallel to the horizon.

By the rotation of Earth the relative position of stars changes a little bit.

In the north pole a galaxy can be observed and in the south pole 2 galaxies.

Jupiter is one of the planets that can be seen from Earth in some seasons and it changes the position due to the rotation of planets around the sun.

A planet beyond Saturn is not possible to be observed from Earth just with the naked eye.
