When you date a rock using radiometric dating, The date when the minerals within the rock cooled and solidified. the number actually means.

Option E. The date when the minerals within the rock cooled and solidified.

The age of rocks is determined by radiometric dating, which examines the proportions of two different isotopes in the sample. Because radioactive isotopes decay at predictable rates, geologists can use instruments like this thermal ionization mass spectrometer to date samples.

In addition to stratigraphic principles, radiometric dating is used in geochronology to determine geological time scales. Some of the best-known methods include radiocarbon dating, potassium-argon dating, and uranium-lead dating.

When you date a rock using radiometric dating, what does the number actually mean? select one:

a. The age of the radioactive atoms used in the dating process.

b. The age of the daughter molecules produced by radioactive decay.

c. The age of the elements that make up the molecules from which the rock is composed.

d. The date when the volcano that produced the rock erupted.

e. The date when the minerals within the rock cooled and solidified.

Overview: Choose two categories of natural resources (i.e., plants, animals, soil, minerals, air, water, or energy sources). The
Usimov [2.4K]

Answer and Explanation:

1. Natural resources are those things which are found on the Earth without human exertion and they are of two kinds which are as per the following:

Renewable natural resources  :

It is a sort of natural resource which can be utilized over and over and they are not going to end sometime in the not so distant future, for instance, wind, sunlight based vitality, water, plants, etc.

Non-renewable natural resource  :

It is a sort of natural resources which are present in very limited quantity and it will end on someday, for example, Coal, petroleum, minerals, etc.

2. Human beings are mostly depended on natural resources and it makes their life easy and comfortable. Let's see its usages one by one.

Historical: Historically, we depended on the renewable natural resources, for example, plants, animals, water and our life started and ended with this form of natural resources when we were not technically advanced.

Present: Presently, we are more technologically advanced and using various technologies to lead our life and we are using fossil fuels at a greater extent and within 30 to 50 years this non-renewable source is going to end and we need to choose our alternative ways also.

Future potential: The way non-renewable natural resources are declining by our present use, we need to switch to renewable sources which are long lasting as well as eco-friendly and that's why the renewable natural sources would be in more demand in near future.

3. These two categories are inter-related because they both provide the energy requirements of the present time, as well as non-renewable natural resources,  are formed by the help of renewable sources since the long geological process.

4. we are vastly using now-renewable sources like petroleum, coal and renewable natural sources like solar energy, wind for our need for energy requirements

Solve for x. <br> 53°<br> 78°<br> (10x - 1)º
KatRina [158]

Answer:

Value of x = 5

Explanation:

Given:

Angle 1 = 53°

Angle 2 = 78°

Angle 3 = (10x - 1)°

Find:

Value of angle x

Computation:

Using angle sum property of triangle

⇒ Angle 1 + Angle 2 + Angle 3 = 180

⇒ 53 + 78 + (10x - 1) = 180

⇒ 131 + 10x - 1 = 180

⇒ 10x + 130 = 180

⇒ 10x = 180 - 130

⇒ 10 x = 50

⇒ x = 50 / 10

⇒ x = 5

Value of x = 5
