The asteroids are orbiting the Sun, each one traveling around the Sun fast enough for the orbits not to degrade
Meteoroids travel around the Sun in a variety of orbits and at various speeds.
Comets go around the Sun in a highly elliptical orbit.
Explanation:
A) How much of the parent (X) and how much of the daughter (Y) were present at the time the rock formed? Choose one of the following and explain why
Answer : C) X = 100 % ; Y = 0 %
At the time when the rock was formed, we would have 100% of the parent and 0% of the daughter.
When a radioactive element in rock initially crystallizes, we will only have the parent isotope inside with no trace of the daughter isotope.
A radioactive material is one that spontaneously disintegrates. It produces the daughter stable isotopes as it emits radiations in the process.
The daughter isotope is the stable form of the parent. So when a rock forms, the daughter would not have been produced.
B) X = 50 % ; Y = 50 %
After the time 5730yrs has elapsed, we are going to have both daughter and parent in the ratio 50% to 50%.
The half-life is the time taken for half of a radioactive isotope to decay to half of its original component.
When a radioactive element is decomposing, it will produce daughter isotopes.
At the half-life time, the parent would have disintegrated by half and produced half of the daughter.
