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.

Answer:
In a divergent plate boundary, two plates move away from one another. Due to this divergent movement of plates, seafloor spreading takes place in the ocean basin along the mid-oceanic ridge and rifting take place in the continental areas. Due to the stretching of the crust, the lithosphere becomes thin, and with more progressive spreading, it results in the eruption of magma at the seafloor. This magma is basaltic in nature, that reaches the surface due to the force exerted by the uprising magma forming convection cells in the mantle. This type of plate motion results in the expansion of the ocean basin and the rift valley in the continental areas forms seas and oceans with increasing time.
The rocks that are formed at the mid-oceanic ridge are the youngest as the magma cools and solidifies very rapidly here. With further moving away from this spreading center the age of the rocks increases.
The divergent plate boundaries are also responsible for the occurrence of deep-focus earthquakes, and it also leads to the formation of volcanoes in its adjacent sides.
Divergent and convergent boundaries exhibit different features and characteristics. Divergent boundaries are associated with tensional stress, normal faults, and volcanic activity from mafic lavas. Convergent boundaries experience compression stress, create thrust and reverse faults, and exhibit volcanic activity from andesitic lavas.
Divergent boundaries are characterized by tensional stress, resulting in normal faults and seismic activity. This type of boundary is also associated with volcanic activity caused by the upwelling of mafic lavas from the mantle. On the other hand, convergent boundaries are the result of compression stresses, leading to plate collisions. These boundaries create thrust and reverse faults and are responsible for seismic activity. Volcanic activity at convergent boundaries is caused by andesitic lavas produced by the partial melting of a subducting plate.

Wegener was intrigued when the same Mesosaurus fossils, an ancient freshwater reptile, showed up on different continents.
What hypothesis did he propose to explain this?
A: The continents were at one time joined together.
B: The Mesosaurus swam between the two continents.
C: The fossils were moved by humans.
D: The fossils must be of different species.
Wegner simply defined it by saying that the continents were all together at one point in time. He defined this by explaining his Continental Drift theory. Hence option A is appropriate.
Alfred Lothar Wegner as is known as one of the foremost and most important people of his time. He was a Geologist as well as a climatologist.
Wegner during his time as a Geologist had given a path-breaking discovery that later the world cherished and became a ground for a lot of future generations. After, looking at the work of the solid spheres over time, and also by finding the Mesosauraus Fossil he could only come to the idea of Continental Drift Theory.
The Continental Drift Theory is such that, Wegner believed that during the Ancient Greek Civilizations, Earth was one big continent., Later on, the Pangea of the whole continent broke, and thus fragments of the continents started to float around and got separated. Hence, option A is correct.

Answer:
A: the continents were at one time, joined together (and then somehow drifted apart)
Explanation:
Answer:
the nature and history of landforms and the processes which create them.
Explanation:
Oceanic crust is younger than continental crust
Oceanic crust is completely under the ocean, continental crust is mostly above the ocean
Oceanic crust is made of metamorphic rock, continental crust is made of igneous rock
Oceanic crust is thicker than continental crust
Answer:
Oceanic crust is younger than continental crust
Explanation:
Oceanic crust is the name given to the terrestrial lithosphere layer, with specific characteristics of composition, thickness and differentiated densities, which constitute the bottom of the ocean basins. This together with the Continental Crust constitute the Earth Crust, yet they are completely distinct in composition, thickness and geological history.
The Oceanic Crust exists at the bottom of all Oceans, filling the spaces between the portions of Continental Crust. Due to its density and thickness, it plunges below the edge of the continental plate into the subduction zones. This forces a new ocean plate to be constantly formed to accommodate displacement of continents and replace the plate that is destroyed by subduction. Thus, the Oceanic Crust can be seen, like the skin, as a healing structure covering the surface areas of the Earth that are no longer covered by Continental Crust due to the continual remoteness of the continents.
