Earthquakes generate compressional waves (p-waves) and shear waves (s-waves). Compared to the speed of shear waves in a given earth material, the speed of compressional waves is the fastest.
Because of this the compressional waves are the first waves to arrive on a complete record of ground shaking. They are also called P waves, which derives from this fact - P is an abbreviation for primary, first wave to arrive.<span>They typically travel at speeds between ~1 and ~14 km/sec.</span>

Which statement BEST describes a case in which push factors contributed to migration?
icang [17]

The correct answer is - D) Jewish immigrants in Poland who fled to the United States to escape religious persecution and seek safety and new opportunities.

The push factors are the factors that make the people move away from one place to another. They are negative factors, and can be economical, political, because of safety reasons etc.

The Jews that fled Poland in order to feel safe and get new opportunities in life in the United States, based on the religious and ethnic persecution, is a nice example of a push factor. In this case we have a push factor motivated on religious and ethnic hatred, which of course will make the people of the persecuted group feel unsafe, threatened, so they will try to move away if possible because their lives are in danger.

1) Joints differ from faults primarily
Zinaida [17]

Answer:

1- Option (C)

2- TRUE

3- FALSE

Explanation:

Joints are the type of fracture that splits the rock into two parts thereby the blocks move away from one another. They are formed due to the tensional force. Whereas, the fault, in simple terms is defined as the cracks or fractures present in the crust of the earth. They are formed by both tensional as well as compressional forces. They differ from one another in terms of displacement. In a fault, the relative displacement between the blocks is more than in the case of joints.

According to the law of cross-cutting relationships, geological features such as faults, igneous intrusions, that cuts across the sedimentary layers on earth are younger than those sedimentary rocks.

A neutron is a neutral particle as it does not carry any kind of electric charge. So, the addition or elimination of neutron from the nucleus does not affect the electric charge of the nucleus. But it can cause changes in the mass within the nucleus. Isotopes originate due to the addition or removal of neutrons from a nucleus.

Hence, the correct answers are given above.
