Why do earthquakes occur near the San Andreas Fault?
The pressure of a nearby volcano about to erupt causes the ground there to quake.
Parts of the transform plates get stuck, pressure builds, and then there is a burst of energy when they suddenly break loose and move.
One plate pushes very very very hard to reverse the motion of the other plate.
Analyze the image provided. Which kind of earthquake wave is represented by the solid lines
P or Primary Waves, because it goes through solids and liquids.
S or Secondary Waves, because it goes through solids and liquids.
How did scientists figure out that Earth has a solid inner core and a liquid outer core?
They drilled all the way into the core and got samples of both the inner and outer cores.
When volcanoes erupt, both solid and liquid rock comes out of the volcano so they realized that the core must already have both.
Scientists used x-rays to get through the mantle and examine the cores as they can't go physically go there due to the increasing pressure and temperature.
They measured the speed and direction of p-waves and s-waves from earthquakes as they passed through Earth.
Point A in the diagram is an example of which kind of boundary plate?
Divergent Boundary Plate
Convergent Boundary Plate
Transform Boundary Plate
True or False: Regarding the Theory of Plate Tectonics (Tectonic Drift), rocks get weathered the same all over the world.
True
False
True or False: Regarding the Theory of Plate Tectonics (Tectonic Drift), the same kinds of fossils are found on continents that are now separated by oceans.
True
False
True or False: Regarding the Theory of Plate Tectonics (Tectonic Drift), mountain chains on different continents are made of the same types of rocks that are the same ages.
True
False
True or False: Regarding the Theory of Plate Tectonics (Tectonic Drift), places that today have colder climates like Antarctica and MN have fossils of organisms that lived in tropical environments.
True
False
