Geophysics

I do, looking at the map it does look like a puzzle and all the continents look like they connect or used to connect.

The driving Forces of Continental drift are both gravity and the motion of the underground Tectonic Plates.

The pressure (due to gravity) in the center of the Earth is so great, that it compresses the otherwise molten metal alloy - to a solid.

The cost of the repairs for Kobe after the earthquake was at least 160 billion yen.

Tectonic plates move from east to west as a whole due to the coreolis (not sure of spelling) effect.

But seriously folks, it's called a "seismogram".

The term for the instrument that measures the seismic waves of earthquakes along faults or tectonic plates is known as a seismograph. These machines measure the force given off by the trembling of the ground due to the force of an earthquake. The strength is measured as magnitude on the "Richter scale" which is a logarithmic quantity. For example, the motion generated by a quake of magnitude 5 on the Richter scale is 10 times as large as that generated by a quake of magnitude 4.

A seismic travel time curve describes the relation between the travel time of a seismic wave and the epicentral distance. It is used to calculate the calculate the distance of the earthquake's epicenter from the seismograph.

this occurs because tectonic plates are under the continents which causes the continents to move

The simplified answer is that it works much in the same way you would determine the source of a sound (which is also in waves). Multiple measurements of the intensity are taken from different locations are used to triangulate an earthquake.

in different parts of Earth's interrior, there are solid and liquid layers. Why is this? scientists believe that as you travel further through Earth's core, the temperature increases as well as pressure. The mantle, the closest layer to the crust, is solid due to its temperature. However, the outer core is made up of liquid because of its temperature as well, but the inner core isn't. It may be the hottest part of Earth, but it's under so much pressure that it remains a solid state.

That there was once a super continent called Pangaea huge land mass was broken into continents that drifted apart. The theory also suggests that the earth is made up of 7 gigantic shifting slabs of the earth's crust. This disproved the more popular (at the time) "raisin" theorem

First of all continental drift happened after Pangea. Pangea was a time when all of the continents were formed together. Then platetectonics moved which caused earth quakes. The earth quakes made the continents drift, and is called continental drift. To learn more on continental drifts and plate tectonics visit http;//www.infoplease.com/ipa/A0001765.html

The diameter of the earth at the equator is 12,756.32 kilometers or 7,926.41 miles. The diameter of the earth through the poles is 12,715.43 kilometers or 7,901.002 miles. Thus the earth is 41 km or 25 miles wider than it is tall, giving it a slight bulge at the equator. This shape is known as an ellipsoid or more properly, geoid (earth-like ball).

(not seismic, seismic wave)Seismic waves are waves of energy that travel through the earth.

When the gravitational force acting on a slope exceeds its resisting force, slope failure (mass wasting) occurs. The slope material's strength and cohesion and the amount of internal friction between material help maintain the slope's stability and are known collectively as the slope's shear strength. The steepest angle that a cohesionless slope can maintain without losing its stability is known as its angle of repose. When a slope possesses this angle, its shear strength perfectly counterbalances the force of gravity acting upon it. Mass wasting may occur at a very slow rate, particularly in areas that are very dry or those areas that receive sufficient rainfall such that vegetation has stabilised the surface. It may also occur at very high speed, such as in rock slides or landslides, with disastrous consequences, both immediate and delayed, e.g., resulting from the formation of landslide dams. Factors that change the potential of mass wasting include: change in slope angle; weakening of material by weathering; increased water content; changes in vegetation cover; and overloading.

The theory is called the Continental Drift Theory. That means that over a long period of time the continents shifted away from each other and formed the earth that we see today. The continents are able to shift and move because they lie on tectonic plates, which are sub-layers that move and float. Tectonic plates cause earthquakes and volcanoes.

The continental drift is still taking place.

There are two main evidences of plate tectonics:

Paleomagnetism- We find that ancient rocks have preserved the magnetism of Earth that was present at that time. Studying the paleomagnetism records, we have found out the polar wandering path, i.e. the path through which the poles moved on the surface of the Earth. The polar wandering path shows clearly that the continents were in a different position than they are now. Even Earth's field reversals are recorded in the rocks.

Earthquake patterns- The earthquake patterns clearly mark the boundaries of the crustal plates which further boosts the credibility of the plate tectonics model.

Mountain building is usually the result of either a lift action or volcanic formation at a plate boundary. There are several ways plate movement can create mountains. Subduction where one plate slides under another can lift the top plate up raising its elevation. In addition with subduction friction can melt the crust and allow volcanic mountain formation. Molten Rock is bouyant so it tends to rise to the surface When two plates collide it is possible they both lift rise up (imagine pushing your fingers together where they both form a peak) driving material upwards. Erosion and gravity prevent the peaks from rising indefinately. Normally there are 3 basic types of plate boundaries, divergent, convergent, and transform.

Subduction may be used as a geological term referring to the process of one of Earth's tectonic plates sliding under another. It also can refer to the act of subducting, especially of turning the eye downward.
