Text of the page (random words):
ic ocean to the west coast of north america it has a greatest height of 4207 m 13 800 ft above the base ocean depth 12 the world s greatest land mountain range is the himalaya karakoram it countains 96 of the world s 109 peaks of over 7317 m 24 000 ft the longest range is the andes of south america which is 7564 km 4700 mi in length both were created bythe movement of tectonic plates 13 it is estimated that there are 500 000 detectable earthquakes in the world each year 100 000 of those can be felt and 100 of them cause damage 14 it is thought that more damage was done by the resulting fire after the 1906 san francisco earthquake than by the earthquake itself 15 a seiche pronounced saysh is what happens in the swimming pools of californians during and after an earthquake it is an internal wave oscillating in a body of water or in other words it is the sloshing of the water in your swimming pool or any body of water caused by the ground shaking in an earthquake it may continue for a few moments or hours long after the generating force is gone a seiche can also be caused by wind or tides mid atlantic ridge 16 each year the southern california area has about 10 000 earthquakes most of them are so small that they are not felt only several hundred are greater than magnitude 3 0 and only about 15 20 are greater than magnitude 4 0 if there is a large earthquake however the aftershock sequence will produce many more earthquakes of all magnitudes for many months 17 the magnitude of an earthquake is a measured value of the earthquake size the magnitude is the same no matter where you are or how strong or weak the shaking was in various locations the intensity of an earthquake is a measure of the shaking created by the earthquake and this value does vary with location 18 the wasatch range with its outstanding ski areas runs north south through utah and like all mountain ranges it was produced by a series of earthquakes the 386 km 240 mile long wasatch fault is made up of several segments each capable of producing up to a m7 5 earthquake during the past 6000 years there has been a m6 5 about once every 350 years and it has been about 350 years since the last powerful earthquake which was on the nephi segment 19 there is no such thing as earthquake weather statistically there is an equal distribution of earthquakes in cold weather hot weather rainy weather etc furthermore there is no physical way that the weather could affect the forces several miles beneath the surface of the earth the changes in barometric pressure in the atmosphere are very small compared to the forces in the crust and the effect of the barometric pressure does not reach beneath the soil 20 from 1975 1995 there were only four states that did not have any earthquakes they were florida iowa north dakota and wisconsin 21 the core of the earth was the first internal structural element to be identified in 1906 r d oldham discovered it from his studies of earthquake records the inner core is solid and the outer core is liquid and so does not transmit the shear wave energy released during an earthquake s amer 22 the swimming pool at the university of arizona in tucson lost water from sloshing seiche caused by the 1985 m8 1 michoacan mexico earthquake 2000 km 1240 miles away 23 earthquakes occur in the central portion of the united states too some very powerful earthquakes occurred along the new madrid fault in the mississippi valley in 1811 1812 because of the crustal structure in the central us which efficiently propagates seismic energy shaking from earthquakes in this part of the country are felt at a much greater distance from the epicenters than similar size quakes in the western us 24 most earthquakes occur at depths of less than 80 km 50 miles from the earth s surface 25 the san andreas fault is not a single continuous fault but rather is actually a fault zone made up of many segments movement may occur along any of the many fault segments along the zone at any time the san andreas fault system is more that 1300 km 800 miles long and in some spots is as much as 16 km 10 miles deep 26 the world s deadliest recorded earthquake occurred in 1556 in central china it struck a region where most people lived in caves carved from soft rock these dwellings collapsed during the earthquake killing an estimated 830 000 people in 1976 another deadly earthquake struck in tangshan china where more than 250 000 people were killed 27 florida and north dakota have the smallest number of earthquakes in the united states ocean cont collision 28 the deepest earthquakes typically occur at plate boundaries where the earth s crust is being subducted into the earth s mantle these occur as deep as 750 km 400 miles below the surface 29 alaska is the most earthquake prone state and one of the most seismically active regions in the world alaska experiences a magnitude 7 earthquake almost every year and a magnitude 8 or greater earthquake on average every 14 years 30 the majority of the earthquakes and volcanic eruptions occur along plate boundaries such as the boundary between the pacific plate and the north american plate one of the most active plate boundaries where earthquakes and eruptions are frequent for example is around the massive pacific plate commonly referred to as the pacific ring of fire 31 the earliest recorded evidence of an earthquake has been traced back to 1831 bc in the shandong province of china but there is a fairly complete record starting in 780 bc during the zhou dynasty in china 32 it was recognized as early as 350 bc by the greek scientist aristotle that soft ground shakes more than hard rock in an earthquake 33 the cause of earthquakes was stated correctly in 1760 by british engineer john michell one of the first fathers of seismology in a memoir where he wrote that earthquakes and the waves of energy that they make are caused by shifting masses of rock miles below the surface 34 in 1663 the european settlers experienced their first earthquake in america 35 human beings can detect sounds in the frequency range 20 10 000 hertz if a p wave refracts out of the rock surface into the air and it has a frequency in the audible range it will be heard as a rumble most earthquake waves have a frequency of less than 20 hz so the waves themselves are usually not heard most of the rumbling noise heard during an earthquake is the building and its contents moving 36 when the chilean earthquake occurred in 1960 seismographs recorded seismic waves that traveled all around the earth these seismic waves shook the entire earth for many days this phenomenon is called the free oscillation of the earth 37 the origin of the name of the san andreas fault is often cited as the san andreas lake however based on some 1895 and 1908 reports by geologist a c lawson who named the fault the name was actually taken from the san andreas valley he likely did not realize at the time that the fault ran almost the entire length of california 38 the interior of antarctica has icequakes which although they are much smaller are perhaps more frequent than earthquakes in antarctica the icequakes are similar to earthquakes but occur within the ice sheet itself instead of the land underneath the ice some of our polar observers have told us they can hear the icequakes and see them on the south pole seismograph station but they are much too small to be seen on enough stations to obtain a location posted by city cyber at 7 49 pm 0 comments monday may 4 2009 china china geography

tenaga diantaranya ialah biogas angin petroleum suria dan air 1 biogas tenaga biogas boleh dihasil daripada kitaran semula bahan buangan domestik dan juga pereputan bahan buangan pertanian setiap hari berjuta juta tan bahan dibuang tanpa dikitar semula yang mengakibatkan pembaziran tenaga yang berharga pereputan bahan buangan domestik dan bahan buangan pertanian akan menghasilkan gas metana yang sangat berguna didalam pembekalan tenaga gas ini terbentuk apabila bakteria menyerang bahan buangan yang mereput gas ini dikumpul dan digunakan untuk menghasilkan elektrik dan juga sebagai bahan api untuk menjalankan jentera gas ini juga digunakan untuk memasak dan menyalakan lampu kebanyakan negara maju biogas sedang dihasilkan di belanda misalnya industri tenusunya sangat maju tetapi menghadapi masalah dalam pembuangan najis najis disebarkan dimerata ladang menyebabkan kebanyakan tempat ditenggelami najis haiwan oleh itu penghadang digunakan bagi membolehkan bahan buangan menghasilkan biogas gas ini digunakan untuk menjanakan elektrik dengan bantuan enjin berkuasa kecil setelah biogas diambil bahan buangan diproses menjadi baja 2 angin kuasa angin telah digunakan beratus ratus tahun dahulu untuk melayarkan kapal layar dan memutarkan kincir angin angin telah digunakan sebagai sumber sumber tenaga untuk menjanakan kuasa elektrik kelajuan angin akan menggerakkan kincir angin bagi menjana tenaga elektrik kuasa angin bergantung pada kelajuan angin sekiranya satu tempat mempunyai kelajuan purata angin dua kali ganda kelajuan ditempat lain maka kincir angin yang pertama akan menghasilkan lapan kali ganda tenaga seperti yang dihasilkan oleh kincir angin yang serupa ditempat lain kuasa angin mempunyai dua kelebihan utama berbanding dengan sumber tenaga yang lain pertama kincir angin yang moden dapat dibina dalam masa yang singkat kedua bagi kebanyakan negara angin banyak terjadi pada musim sejuk ketika elektrik diperlukan dengan banyaknya kuasa angin telah digunakan untuk menghasilkan elektrik dengan penggunaan kincir angin yang mana batang yang diputar oleh bilah menjalankan sebuah penjana elektrik penggunaan kincir angin untuk menghasilkan tenaga elektrik adalah lebih murah dan selamat negara negara maju telah mula membangunkan kincir angin bagi menghasilkan elektrik kerana ianya dapat menjimatkan kos untuk membolehkan kincir angin berfungsi dengan lebih efektif tapak untuk menempatkan kincir angin hendaklah dipilih berdasarkan kelajuan kekuatan dan arah angin 3 suria matahari penting kepada manusia kerana membekalkan cahaya dan haba di bumi kebanyakan tenaga lain seperti angin pada asalnya berpunca daripada tenaga matahari tenaga dikeluarkan apabila bahan api fosil dibakar merupakan tenaga matahari yang tersimpan di dalam tumbuhan sejak berjuta juta tahun yang lalu apabila tenaga daripada matahari memancar ke atas permukaan daun tenaga ini ditukar kepada tenaga keupayaan kima dan disimpan dalam tumbuhan melalui proses fotosintesis tenaga suria adalah tenaga yang diperolehi secara terus daripada matahari ia digunakan di dalam pelbagai bidang pertanian haba daripada matahari digunakan untuk memanaskan ternakan terutamanya di musim sejuk struktur rumah hijau direkabentuk agar tumbuhan dapat tumbuh di dalam persekitaran yang terkawal rumah hijau direka bagi membolehkannya memerangkap tenaga daripada matahari untuk digunakan dalam fotosintesis sebahagian besar tenaga adalah disimpan dalam tumbuhan matahari menghasilkan tenaga suria yang boleh digunakan untuk menjanakan kuasa elektrik di rumah kediaman tenaga suria digunakan untuk memanaskan air dengan menggunakan pemanas suria yang dipasang di atas bumbung bumbung rumah teknologi moden telah mereka sel fotovolta atau dikenali sebagai sel suria yang berupaya mengubah tenaga cahaya matahari kepada tenaga elektrik suria akan menghasilkan tenaga yang murah dalam kuantiti yang banyak juga menghasilkan bahan bahan baru dan mungkin digunakan untuk memusnahkan kuman beracun tenaga cahaya matahari boleh ditukar menjadi tenaga elektrik secara terus dengan menggunakan sel suria dalam industri pertanian sel suria digunakan untuk memberi kuasa kepada pam air untuk menyalurkan air dari kolam ke ladang 4 air tenaga dari aliran air sungai boleh digunakan untuk menggerakkan kincir air pada zaman dahulu tenaga dari aliran air sungai digunakan untuk mengerakkan kincir air untuk mengisar jagung kemudiannya penggunaannya diperluaskan ke kilang kilang dan lombong jenis kincir air yang digunakan bergantung kepada kelajuan arus sungai penggunaan kuasa air telah dimajukan dengan pelbagai cara contohnya air digunakan untuk menjana kuasa elektrik air yang mengalir dengan kelajuan yang tinggi akan memusingkan bilah bilah dalam yang melengkung pada turbin air dan seterusnya menjana kuasa elektrik elektrik yang dijanakan oleh air dipanggil hidroelektrik kuasa hidroelektrik merupakan sumber tenaga yang bes...
