Answer:
Answer are written below:
Explanation:
1) It is very important to have a universal method established to guide archaeological excavations because you have to planned out everything in order to find a method or a way to work through the study.
2) Understanding our past is important to our future because studying history enables us to understand the world better and the past gives us courage and protects us from harm.
3) It would be more challenging to be a prehistoric archaeologist as compared to historical archaeologist because historic archaeology is easier to study due to the presence in written form whereas Prehistoric archaeology is very difficult to study due to no written records are present.
4) I will work as an academic archaeologist as compared to cultural resource management (CRM) archaeologist because academic archaeologists are active researchers in their field which also published their work in the books, journals, and popular publications.
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.

Explanation:
Hope it helps!
Answer:
Mountains or other topography
Explanation:
This makes sure the air rises and cools in temperature, but because they cant hold that much of the water they form into clouds.
Nevertheless, the unifying influence of the monsoons on the Indian subcontinent is quite perceptible. ... These monsoon winds bind the whole country by providing water to set the agricultural activities. Thus, in view of the above the monsoon is considered as a unifying bond for this subcontinent.
