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.
Answer:
a) w = 98°
b) x = 137°
Explanation:
The reason is that they are angles at a point
Which means they are equal to 360°.
Example;
a) 165° + 97° + w = 360°
262° + w = 360°
You then group like terms
w = 360° - 262°
w = 98°
Note: The reason is the same for b)
Answer:
architecture exists to create the physical environment in which people live but architecture is more than built environment it's also part of our culture. it stands as representation of how we see ourselves as well as how we see the world

Answer:
In 1619, the first representative legislative assembly in the New World met at the Jamestown church. It was here that our American heritage of representative government was born. Since New England was outside the jurisdiction of Virginia's government, the Pilgrims established a self-governing agreement of their own, the "Mayflower Compact."
