What Are Tectonic Plates

In geology, the Earth's outermost layer is called the lithosphere, which contains the crust and solid, rigid rock. Below the lithosphere is the asthenosphere, which flows more like liquid. The Earth's lithosphere is broken up into tectonic plates — massive, irregular slabs of solid rock that are assumed to average about 70 miles thick. The Earth consists of seven major tectonic plates (underneath the continents as well as the oceans) and many more, smaller ones. These plates float, or "ride," on the asthenosphere.
Tectonic plates sometimes collide. The world's great mountain ranges were formed when plates collided and the rock had nowhere to go but up. Tectonic plates are moving slowly, rubbing against each other or even in opposite directions, which is what causes the majority of the earth's seismic and volcanic activity. If you study where the tectonic plates are located, you'll notice that the vast majority of mountain ranges, volcanoes, and earthquakes occur along the edges of these plates, while the centers of the plates remain relatively stable, in geologic terms.

Doodle Bugging Crew

Doodle Bugging Crew consists of followings:-

1. Party chief:-
                        Seismic crew operates under the supervision of party chief.

2. Party Manager:-
                             Day to day field activities are directed by the party Manager.

3. Permit Person:-
                             It deals with local people to Obtain land and resources.

4. Transit surveyor:-
                              Marks the place where survey has to be done.

5. Shot Hole Driller:-
                                Makes holes for dynamite.
Ground crew 

> Foreman:-
                     Ground crew is usually headed by foreman. which consists of jug hustlers and cable handlers.

> Jug Hustlers:-
                         Jug hustler usually places Geophones.

>Cable Handlers:- 
                              Cable Handler deals with all the cable Work. 

Geological Survey Steps

Geological Survey Steps:-

1. In geological survey we check out the out craft structure , (fault and fold) and lithologies.

2. Meteorological Survey:-
                                         Surveyor must be aware of the meteorological condition that is weather condition.

3. Base Camp:-
                          The surveyor needs to establish a base camp.

4. Geological Camp:-
                                  The surveyor must know the symbols and routes.

5. Previous Literature:-
                                    The surveyor must know the history and the previous literature of that particular area.

6. Economic View Point:-
                                        Before doing a survey it is concluded that, survey of this area would be economical or not. He must know the latitude and longitude of area.

7. Equipment:-
                      The surveyor must have the proper equipment.

8. Lease agreement:-
                                 One who wants the survey must have a least agreement from the government.
                                          

Difference Between Geology and geophyscis

Q) What is geology and geophysics? and what is difference between them?

Geology :-
                It is the study of the earth. The materials it is made from, the structure of those materials and the process that happened to them overtime.

Geophysics :-
                    Geophysics involves using physical theories and measurements to determine the earth properties.

Difference :-
                    The geologist usually studies the earth through direct observation in the field and analysis of soil rock sample whereas geophysists emphasis using physical principles to study the earth material and structures usually in quantitative way and mathematical modeling.
