The answer is The unsorted sand and rock is the least porous. The porousness of a solid material is dependent on the size of holes within it. This can be tested by how quickly, the material can pass a liquid through it. The bigger the holes, the higher the porousness, In this case, the unsorted sand and rock have the smallest holes between its particles.

Answer:
D. They are both influenced by mountain ranges
Explanation:
Both the Santa Ana Winds and Foehn go right through and near them, so it stands to reason their wind would be affected.
The correct option is B.
Nationalism is an economic and political system that is characterized by promotion of the interest of a particular country with the aim of gaining or maintaining self governance over the groups' home land.
Nationalism has never been used as a force of murder and genocide.
Answer:
1) The Haywired scenario—headed by Tom Brocher and others—is a preparatory measure meant to ready law enforcement, fire fighters, utility workers, etc. for damage to infrastructure that will happen during a great Hayward earthquake. The right option is True.
2) The Haywired scenario plans for a similar amount of shaking compared to the 1868 Hayward earthquake. The correct option is True.
3) The amount of damage due to the 1868 Hayward earthquake is equal to our expected consequences following the upcoming next Hayward fault earthquake. The right answer is False.
Explanation:
1) The Haywired scenario is a 3D virtual sequence in which a hypothetical earthquake of magnitude 7 in the San Francisco Bay can cause chaos. An interdisciplinary panel of scientists have designed a hypothetical mainshock in the HayWard Fault and its possible impact and consequences of the ground shaking beneath Oakland. The idea behind this scenario is to improve the quality and reactiveness of Internet and telecommunication to react to such a hazard. They are seeking to prevent gaps in knowledge and communication needs and solve any "communication congestion" so that law enforcement, fire fighter, utility workers and any other service to work effectively under such a disaster.
2) The Hayward scenario is based on a large earthquake that hit the San Francisco Bay in 1868. Its magnitude was 6.8 and there is a high probability of such a massive quake occurring again. Scientists are also concerned with “recurrence interval” on the fault as this type of events tend to be equally or exceed the previous one in a cyclical flow of time.
3) The main difference between the earthquake that stroke in 1868 and the currently expected is that at that time damage was contrived to a small number of buildings as the land was just developing with scarce population. Conversely, an earthquake of that magnitude would threaten more than 7 million people leaving near the Hayward Fault. Apart from causing a vast destruction of infrastructure and building, it would seriously hit the national economy.
