Story of Lesson 1-3

โครงสร้างโลก

Structure in the study of the world. Wave analysis was used. Wave of primary and secondary waves. The waves in the medium. The properties of the P waves can pass through an intermediary not only s-wave state is solid

Division of the world

1. Lithosphere in the world with a depth of 100 km of rocks have properties of solid 2. Asthenosphere can be divided into two areas? - Moving the lower shock wave speed and s p are the plastic properties of rocks? - The area has changed. Seismic velocity increases in the rate is not uniform?

2. Associate Sphere. Below the asthenosphere. Seismic velocity increases regularly. Because of the solid rock, and 4. The Earth's outer layer. So, under the Sphere. P wave s wave speed increases because the state can not pass through the liquid 5. Greats in the world. At a depth of 5140 km p-wave and s are relatively constant rate. Because the Earth's core in a solid.

The structure of the physical components 1. Tectonics. The outer crust is divided into continents. And oceanic crust. Boundary between the crust and mantle, which is broken by Fiona's rock Online. Ho Ro Mo or demarcation line in Leipzig


3. Mantle. Mantle rocks on the ultrasound, may figure. The bottom is a stone that can withstand the pressure and temperature conditions, 3. Earth's core. Can not be specified. It requires knowledge of the theory of the origin in the solar system
โลกและการเปลี่ยนแปลง

And the Dr. Alfred Wegener was hypothesized that The land was originally the same as the thousands of Georgia and is divided into two parts: the Sierra for a Laurel, North Greenland and North America with Eurasia and the USA are increasing Wanaka, South Africa, Australia, India, Madagascar.


That shows that the world has ever combined into one.
 1. Evidence of the boundaries of the continent.
 2. Evidence of the similarity of the rocks and the mountains.
 3. Evidence of rocks caused by the accumulation of sediment from the glaciers.
 4. The evidence of fossils

The resulting motion of the Earth? Of heat transfer in the world. The solid crust covering the bottom of the ocean ridge. The hot water flows up. When water temperatures dropped to a very dense layer and into the mantle at subduction trenches beneath the sea. Hot water circulation circuit is called. Heat cycle?
The motion of the Earth
1. The earth moving apart due to the pressure of the hot water in the Earth. Bend to the earth. The balance will be stretched and thinner. Born with a crack and fell down. The Earth will melt into a sedimentary rock. Max
2. The Earth moves together. - The Earth collided with the Earth ocean ocean When the Earth moves toward the ocean. The aged. Density much lower temperature, causing subduction trenches. The upper plate has a low melting point. Some have become magma
The Earth Ocean Earth collided with a continent. The Earth's oceans is a very dense rock into the Earth beneath the continents. Cause it to curve into the mountains on the Earth Europe - a geographical continent collided with the Earth Europe on a collision will occur as the high mountains along the length of the continent. 3 The earth moves through or cut the cycle of convection and pressure of the underwater ridge. As a result, the Earth moves and slash through it. Marks a transcript form

Changes in the crust:

1. Stratigraphy of the arc. Change the properties of the rock that is plastic. Can be classified into two types of rock layers bend bend the hood. The curve is a curve of the roof of the boat rocks the hood up. A curve that curves down

2. The faults are classified into three categories - normal faults. A fault with the dip of the plane of motion. The stone ceiling moves down - reverse faults. A fault with the dip of the plane of motion. The ceiling has moved up the rock - along the fault. A fault with the dip of the plane of motion through 90 degrees.

ปรากฏการณ์ทางธรณีวิทยา

Geological phenomenon Earthquake is a phenomenon Nas a result of the motion of the Earth. To move the rock to fracture and the energy is transferred rapidly to the adjacent rock layers in the form of seismic waves. Which radiates in all directions from the origin. And through intermediaries, within the world on the earth's surface. Where is the origin of the vibration of the earth, or earthquakes that. Earthquake Center. The position on the earth's surface above the center of an earthquake. Point above the center of an earthquake

Earthquake Center. Can be classified into three levels:

1. Quake was shallow center, less than 70 kilometers from the Earth's surface.
2 earthquake, the moderate center. Depths between 70-300 km
3. Earthquake Center, an in-depth. Depths greater than 300 km.

Seismic has two kinds of waves in the medium is the wave of the primary waves and secondary waves, the surface is a wave that moves slowly over the waves as there are 2 types - Waves of Love waves and particles as vibrations in the plane - wave Rayleigh. The mass media is the wave of vertical movement

The repeated occurrence. Fault with the power of death over the period of the anniversary of the earthquake that occurred at that course and then repeats the same request. Fault is a fault with the power of the earth to move
Volcanoes occur in the vicinity of the Earth's collision. Caused by the eruption of magma. Gas and ash from beneath the earth's crust. Previous bombings have signs such as Land in the area around the volcano caused the vibration noise caused by movement of magma. When the magma to the Earth's surface is called lava.

Penalties and interest of the volcano. - Soil degradation caused by the decay of volcanic rock fragments have a lot of minerals - a tourist attraction - a dig for diamonds. Jewelry penalty - the greenhouse effect - acid rain - can cause tsunami waves
