Answer:
c. are too old (predate sedimentary deposition)
Explanation:
Radiometric dates calculated from minerals in sedimentary rocks produce ages that are too old and often predates the sedimentary deposition.
Radiometric dating involves the uses of radioactive elements in rocks to measure the absolute age of rock.
It involves comparing the daughter to parent ratio because the decay started when the minerals formed in a rock in a period of crystallization or metamorphic event.
- Sedimentary rocks are often made up of re-worked minerals.
- They are derived from pre-existing igneous and metamorphic rocks.
- When radioactive minerals from these sources finds their way into sediments, they give the age of their parent rock and not that of the sedimentary rock because their activity is not being reset.
The most logical answer sounds like D.
If it grows underwater then of course it's able to withstand water. <span />
Answer:
The Tropic of Cancer borders the regions of <em>Mexico, the Bahamas, Egypt, Saudi Arabia, India and Southern China </em>while the Tropic of Capricorn borders the regions of <em>Australia, Chile, Southern Brazil and Northern South Africa.</em>
Explanation:
In order to learn more about the answer, let's consider describing what the Tropic of Cancer is and what the Tropic of Capricorn is.
Tropic of Cancer- This is also known as "Northern Tropic." It is said that at the time of its naming, the sun was positioned in the <em>Cancer constellation </em>(one of the constellations of the zodiac). It is located at 23.5 degrees north of the equator and runs through the regions mentioned above.
Tropic of Capricorn- This is also known as <em>"Southern Tropic."</em> It is said that at the time of its naming, the sun was positioned in the Capricorn constellation. It lies at 23.5 degrees south of the equator and runs through the regions mentioned above.

<u>Equator- </u>The imaginary line that divides the earth into the Northern and Southern Hemispheres.
i want to say it is D. because i believe that they are nocturnal animals and they are found in deserts.
