Create a 5 pages page paper that discusses wegener and his viewing the nature of continents. We can determine information about the earth’s core by studying the paths and characteristics of seismic waves from earthquakes and experiments on surface minerals and rocks at high pressure and temperatures. This core spins and creates the earth’s magnetic field.P waves and S waves are seismic waves that scientists use to study the inner core of the earth. Computer models, along with seismological data, allow scientists to research convection within the earth’s core.A. . When the rock is new, the grains may align themselves with the prevailing magnetic field. as the stone cools, the grains are frozen, and the seafloor expands.When the seafloor expands, the banding of rocks is striped with rock-orientated in different directions. This proves that the magnetic poles have reversed many times.Continental crust is lighter than oceanic crust and is granite, while the oceanic crust is basaltic. Oceanic crust subducts while continental crust does not. Oceanic crust is also much younger in geological age.A. Subduction processes result in the mantle’s melting, which produces a volcanic arc as the lighter rock is forcibly submerged.
.B.A. Divergent boundaries form rifts.As the plates spread apart, a new crust is created. One theory for this is the push-pull theory, and the other idea is convection.In a reverse fault, one side moves up, and in a usual spot, one side moves down. An average mark is a fault in which the hanging wall has moved downward relative to the footwall. A reverse fault forms when the hanging wall moves up. Forces that create reverse faults are compressional, while details that make normal faults are extensional.
2 A. Andean Mountains form along the Western side of the South American continent where the Nazca tectonic plate is colliding with the South American vessel.
The reaction of carbonic acid with limestone. Carbonic acid is formed as rain passes through the atmosphere picking up CO2, which then dissolves in the water. Once it reaches the ground, it passes through the soil to provide much more CO2 to form a carbonic acid solution that dissolves calcium carbonate.  .The transport of wind, ice, or water. Rainfall, vegetation, temperature, deforestation, and topography.A Striations are scratches, or gouges cut into bedrock by glacial abrasion. They are usually multiple, straight, and parallel.Striations represent the movement of the glacier using rock fragments and sand grains as cutting tools.
