#1 How was the earth born ?
EARTH |
Earth formed around 4.54 billion years ago, approximately one-third the age of the universe by accretion from the solar nebula, volconic outgassing probably created the primordial atmosphere , And then the ocean but the early atmosphere contained almost no oxygen,

#5 Why do you call earth ?
The name earth derives from the eight century Anglo saxon word erdo, which means ground or soll,
It because earth later and then earth in middle english ,Theses words are all cognates of jord the name of the giantess of norse my earth ,
Normal:- Faults form when the hanging wall drops down ,
The forces that create normal faults are pulling the sides apart or extensional.
Reverse :Revers faults from when the hanging wall moves up , The forces when forces creates reverse faults are compressional pushing the sides together
Transcurrent or strike slip faults -It have walls that move sideways not up or down ,

#8 Earth Facts ?
Earth is the planet from the sun and is the largest of the terrestrial planets, The earth is the only planets in our solar system not be named after a Greek or Roman deity , The earth was formed approximately 4.54 know planet to support,
Facts about the Earth
- This declaration is happening almost imperceptibly at approximately 17 milliseconds per hundred years although the rate at
- The realization that earth is a planet and a planet among many others was established gairly recently in the 17 century the realization came through by the combined forces of ancient
- Plato correctly deduced that the earth is spherical but this idea would take root and be proven much later,
- The name "earth - is at leasi 1.000 years ol and d it is a germanle word which simply translates to "the ground " it is not know who came up with it but it is the only planet that wasn't named after a greek or roman god,
- It has an equatarial radius of 6.371 k/m 3.958 mi, and a polar radius of 6.356 k/m 3.949 mi meaning , it is not completely spherical but rather budget at the equator due to rotation,Earth has a mass of about 6.6 sextillion tons and volume of about 260 billion cubic miles trillion cabic k/m
- The surface area of earth is about 197 million square miles 510 millions sq k/m,
- Around 71% of the surface covered by the water and 29% by land ,
- The water is 3% fresh and 97% salted of that 3% freshwater over 2% is frozen in ice sheets and glaciers meaning that less than 2% is freshwater found in takes rivers and the under ground,
- The thickness of the atmosphere is about 60 miles 96 k/m,
- The atmosphere of earth is divided into 6 layers troposhere stratosphere mesosphere thermosphere exosphere and ionosphere,
- The highest temperatures on earth can reach up to more than 110 degrees, fr 148 around-126 degrees may be ever lower,
- Earth has the greastest density out of the planets in the solar system,
- Together with the inner core earth also has an outer core with the crust being the mantle and the thickest layer, it is a mixture of maten eock about 1.800mi 2.900k/m thick and that has the consistency of caramel,
#9 What Earth distance from sun ?
Earth distance from sun 152.08 million k/m
#10. What is earthquake explain ?
An earthquake is the result of a sudden release of stored energy in the earth's crust that creates seismic waves ,,,, At the earth's surface earthquake may manifest themselves by a shaking or displacement of the ground , Sometimes they cause tsunamis, while may lead to loss of life and destruction of property,
#11 What is type of earthquake ?
Types of earthquake & faults .There are four different types of earthquakes
- Tectonic
- Volcanic
- Collapse
- Explosion
Volcanic :- A volcanic earthquake is any earthquake that result from tectonic forces which occur in conjunction with volcanic activity,
Collapse :-A collapse earthquake are small earthquake in underground caverns and mines that are caused by seismic waves produced from the explosion of rock on the surface ,
Explosion:- An explosion earthquake is an earthquake that is result of the detonation of a nuclear and or chemical device,
Explosion:- An explosion earthquake is an earthquake that is result of the detonation of a nuclear and or chemical device,
#12 Whats types of faults in earthquake ?
- Normal
- Reverse
- Transcurrent or strike -slip faults
Normal:- Faults form when the hanging wall drops down ,
The forces that create normal faults are pulling the sides apart or extensional.
Reverse :Revers faults from when the hanging wall moves up , The forces when forces creates reverse faults are compressional pushing the sides together
Transcurrent or strike slip faults -It have walls that move sideways not up or down ,
