Answer:
C .radioactive dating each year
Explanation:
In determining the absolute age of two rocks, the most important thing is the radioactive dating of the rocks to compare the radioactive isotopes within them.
Absolute dating involves ascribing numerical age to a rock body. It is usually done by the process of radioactive dating in which the number of daughter to parent isotopes are compared.
This helps to give a precise numerical age to a rock.
- The other choices are for relative dating.
Answer:
-1/5
Explanation:
It is an established mathematical proof that the slope of line A perpendicular to another line B is the recoprovaknofokad
Hence the slope of B = the negative reciprocal of B
Given that ; lines s and t are perpendicular ;
Slope of S = 5 ;
The slope of T = - 1/5
Answer:
A.Bern is the capital city of Switzerland
Central America does not produce wheat, rye or canola or apples or bauxite for aluminum or fir lumber but it does produce many tropical fruits like mangoes, papayas, guavas, oranges, limones, and vegetables like avocados and cilantro and cumin.
Human activities directly contribute to landslides especially the kaingin system practiced by some farmers and the ruthless illegal logging for some loggers. These selfish practices harmed the nature causing soil erosion and worse landslides due to the absence of trees.
