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.

I Got The Answer from of my Science Teacher Mr. Isaacson at Columbus Tustin Middle School he is The best of The best Even Though i Dont Really understand science he makes it easier for me to understand. :)

Granitic rocks are intrusive, which means they crystallized underground. Basaltic rocks are extrusive, meaning they crystallized above ground. Also, basaltic rocks are more mafic, and granitic rocks are more felsic.

There are many Taiwan Earthquakes, but i believe i know which one you are talking about... the earthquake that occurred on September 21, 1999. If this is the one, then the plates would be the Eurasian and Philippine plates. What happened is that the Philippine Plate pushed against the Eurasian plate without any movement for a long period of time. This is commonly known as a seismic gap. Finally, the pressure built so high, that it slipped resulting in an earthquake.

It is a scientific theory under investigation (experiments, statistical analysis) this moment which is based on the thought that earthquake in a region is a time repeated phenomenon. Therefore, by drawing maps including many neighboring seismic regions with the date that an earthquake hit each one of them, one could create the sequence of these events. Finally, by following that sequence in a long term basis, one would realise that there will be regions in the map which await an earthquake as they compose part of the mentioned sequence.

In simple words, it is like you want to build a 500 pieces puzzle, only now someone else is telling you where to put each piece (the earthquake). The puzzle is the map thus the more pieces you put, the more you can see on your puzzle (map) what is missing. Therefore the more accurate you become to your prediction of the location of the next piece (earthquake).

By measuring the difference in arrival times at a seismometer station they can be used to determine the distance to the epicentre of an earthquake.

They may also be used to estimate the properties of the subsurface and it's structure (refraction and reflection seismology).

continental drift can change there earth in many different ways like land forms and climates for example the Hawaiian islands were originally and under water volcano but over the years it has traveled under the crust making new land.

Continental drift is a concept relating to the movement of the Earth's continents. The proving of the continental drift theory came from evidence found around the world.

Foremost, scientists had discovered that similar plants and animal fossils were found in or around different continents, suggesting that they were once joined.

The theory of plate tectonics also supported continental drift. If one were to look at a global map, the complementary arrangements between South America and Africa can be easily seen.

the core shakes causing the plates to move forming volcanoes ect..(that is why volcanoes spit out lava because it comes from the core.)

The P Waves. Then the S Waves.

Francis Bacon noticed in 1620 that the outlines of the continents fit together like a jigsaw puzzle, but did not suggest a theory of why.

Benjamin Franklin wrote in 1780 that the crust of the Earth must be a shell that can break and shift by movements of a fluid below

The proper theory of continental drift was suggested by Alfred Wegener in the early 20th century. He published a book "The origin of the continents and oceans" proposing the existence of a supercontinent he called Pangaea about 250 million years ago.

He was unable to explain a driving mechanism, which is one of the reasons why his theory was at first rejected by the scientific community.
