B - when the warm, moist air and the cool, dry air meet, they create instability in the atmosphere
In creases the density of the crust i think...
Earthquakes produce P and S waves. The P waves are fast and of a higher frequency than S waves. P waves reach a point first and can pass through liquid media while S waves reach after and the lose much of their energy while passing liquid media. This is because S-waves are shear waves and require rigid/inelastic media for transmission.
During an earthquake, there is usually a shadow zone (where there is no destruction because S-waves did not reach) formed right above the epicenter of the earthquake. This is due to the fact that the S-waves were unable to transit through the liquid inner core of the earth before reaching the earth's surface. Only P-waves are registered in this shadow zone.

Explanation: im sorry, that this is long.
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.
