The technique called radiometric dating is based on

Geography
1 answer:
Dima020 [189]3 years ago
3 0

Answer:

D) the steady, clocklike decay of certain radioactive isotopes over time.

Explanation:

Geologists use radiometric dating to estimate how long ago rocks formed, and to infer the ages of fossils contained within those rocks.

For example, when rocks are formed, such as igneous rocks (formed when molten rocks cools), certain radioactive atoms are trapped inside the rocks during this formation process. Then these radioactive atoms decay over time.

The age of the rock can be estimated by comparing the occurring radioactive isotope within the material to the abundance of its decay products, which form at a known constant rate of decay.

From the options;

A) this is about the formation of the radioactive molecules and not about radiometric dating

B) this is radiocarbon dating (cabon dating/carbon-14 dating)

C) the <em>assumption </em>is wrong since the radioactive isotopes decays not accumulate.

D) the corect option as I explained earlier.

How do mountain chains provide evidence to support the theory of the continental drift

Theory of Continental Drift

If you take a look at a map of the earth today, you will see the current locations of broken land masses that constitute the earth. However, would you believe if someone told you that these broken land masses were once connected to each other as one huge supercontinent?  Well, this claim was made in the 90’s by Alfred Wegener, a German polar researcher, meteorologist and geophysicist who died in 1930.

Wegener’s theory of continental drift states that the existing continents of the earth were once glued together forming a super landmass. Over time, the landmass broke and drifted away and is still drifting to this day. In his proposal, he stated that the super content, which he named Pangaea, meaning ‘’all earth” once existed. The supercontinent was surrounded by water bodies, mainly oceans, and seas.

Which phrases describe air density ? Select three options.
Phantasy [73]

Answer: The correct options are:

<em>exerts more pressure as it increases </em>

<em>measures how tightly molecules are packed </em>

<em>equals mass divided by volume</em>

Explanation:

Air density can be described as mass per unit of volume of the volume of air.

As the altitude increases, the air density tens to decrease. Hence, option A is not correct.

The density of the air determined how many atoms of air can occur in a particular volume, In other words, it determines how tightly or loosely atoms of air are packed in a particular volume.

Hence, when the air density will increase, the molecules will be more tightly packed and the pressure will be more.

irina [24]

They are found in the tundra regions of Eastern and central Europe. Mostly covered in permafrost, in some areas this frost has melted. The Drunken forest is the reference to the shallowness of where the trees roots are and then the trees start to tip over (Like a drunk man LOL). But within the Northern Hemisphere it alters the life around it and also destroys roads and buildings
