The correct answer is - B) convection currents in the mantle.
There's multiple tectonic plates on the surface on the planet, around 17 from what is known so far, but as the scientific methods are developing there might be few more discovered in the years to come.
These plates are all moving, only few cm per year, but on the long term it influences and changes everything on the surface on the Earth.
The movement of the plates is the result of the convection currents in the mantle layer beneath. These convection currents are essentially the combination of the high temperatures, high pressures, and viscous metals, and they managed to break up the crust on the surface, and with its push force, they are slowly moving the plates.
With the movement of the plates and their collisions and moving away, lots of earthquakes and volcanoes are appearing all over the plate boundaries.
Answer:
The probability of children who have both a cat and a dog is 63/100 or 63%
Explanation:
45/100 or 45% of the children already have a cat so you would add that to the amount of kids who already have a cat and a dog (18%)...Therefore 63% of students have a cat already may also have a dog.
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>
Answer:
When residents of several Southern California cities were asked to draw maps of their residential areas, middle- and upper-income individuals included more details and area, while lower-income individuals included fewer details and area.
At first you have to write the variables out which are
now you have to combine like terms
now you add these two variables and end up with answer of
