: Seismic waves are responsible for the earth trembling during earthquakes. An earthquake occurs as seismic waves travel through the interior of Earth’s surface. A seismograph measures the characteristics of these waves such as how fast they travel as well as their strength.
By studying these attributes in different places, scientists come to understand the makeup of earth’s internal structure. The type of seismic waves most important to this study are body waves which travel through the earth’s interior

Answer:
Lines of latitude measure north-south position between the poles. Lines of latitude are all parallel to each other, thus they are often referred to as parallels.
Lines of longitude, or meridians, run between the North and South Poles. They measure east-west position. The prime meridian is assigned the value of 0 degrees, and runs through Greenwich, England. Meridians to the west of the prime meridian are measured in degrees west and likewise those to the east of the prime meridian are measured to by their number of degrees east.
<span>Conduction probably is the main method in the crust, but do not underestimate fluid convection. Every time you find a hot spring, then that is an example of fluid convection. ... Since these two are separate heat transfer from the outer core to the mantle is also mainly by conduction</span>
