Dry Soil


Farmer are greatly suffer for waterless of soil. as a result of they're can't product any crops that desires clay varieties soil.Artificial watery system could not solve this drawback.Villagers try and solve this drawback.Sometimes they're prepare frog wedding however it's not answer simply its suspicious.Bangladeshi individuals believes Dua is effective for rain and it'd be solve this drawback.However ,has several reason for Dry Soil.Now we are able to Dry soil pic:

Volcano history.............

A volcano may be a rupture on the crust of a planetary-mass object, like Earth, that enables hot volcanic rock, volcanic ash, and gases to flee from a rock chamber below the surface. Earth's volcanoes occur as a result of its crust is broken into seventeen major, rigid tectonic plates that float on a warmer, softer layer in its mantle. so, on Earth, volcanoes are usually found wherever tectonic plates are radiating or convergence. as an example, a mid-oceanic ridge, like the eastern Ridge, has volcanoes caused by divergent tectonic plates pull apart; the Pacific Ring of fireplace has volcanoes caused by merging tectonic plates coming back along. Volcanoes may also type wherever there's stretching and dilution of the crust's interior plates, e.g., within the geographical area Rift and therefore the Wells Gray-Clear water volcanic field and river Rift in North America. this sort of geological phenomenon falls below the umbrella of "plate hypothesis" geological phenomenon. geological phenomenon removed from plate boundaries has additionally been explained as mantle plumes. These supposed "hotspots", as an example Hawaii, are postulated to arise from upwelling diapers with rock from the core–mantle boundary, 3,000 kilometer deep within the Earth. Volcanoes are sometimes not created wherever 2 tectonic plates slide past each other.

Erupting volcanoes will cause several hazards, not solely within the immediate neighborhood of the eruption. One such hazard is that volcanic ash may be a threat to craft, particularly those with jet engines wherever ash particles may be liquified by the high operative temperature; the liquified particles then adhere to the rotary engine blades and alter their form, disrupting the operation of the rotary engine. giant eruptions will have an effect on temperature as ash and droplets of sulphuric acid obscure the sun and funky the Earth's lower atmosphere (or troposphere); but, they conjointly absorb heat radiated up from the world, thereby warming the higher atmosphere (or stratosphere). traditionally, questionable volcanic winters have caused ruinous famines.

How Earthquake Attacks and Spreads Fast?

What is Earthquake?
An earthquake (also known as a quake, tremor or temblor) is the result of a sudden release of energy in the Earth's crust that creates seismic waves. The seismicity, seismism or seismic activity of an area refers to the frequency, type and size of earthquakes experienced over a period of time.

Earthquakes are measured using observations from seismometers. The moment magnitude is the most common scale on which earthquakes larger than approximately 5 are reported for the entire globe. The more numerous earthquakes smaller than magnitude 5 reported by national seismological observatories are measured mostly on the local magnitude scale, also referred to as the Richter magnitude scale. These two scales are numerically similar over their range of validity. Magnitude 3 or lower earthquakes are mostly almost imperceptible or weak and magnitude 7 and over potentially cause serious damage over larger areas, depending on their depth. The largest earthquakes in historic times have been of magnitude slightly over 9, although there is no limit to the possible magnitude. The most recent large earthquake of magnitude 9.0 or larger was a 9.0 magnitude earthquake in Japan in 2011 (as of March 2014), and it was the largest Japanese earthquake since records began. Intensity of shaking is measured on the modified Mercalli scale. The shallower an earthquake, the more damage to structures it causes, all else being equal.

At the Earth's surface, earthquakes manifest themselves by shaking and sometimes displacement of the ground. When the epicenter of a large earthquake is located offshore, the seabed may be displaced sufficiently to cause a tsunami. Earthquakes can also trigger landslides, and occasionally volcanic activity. In its most general sense, the word earthquake is used to describe any seismic event — whether natural or caused by humans — that generates seismic waves. Earthquakes are caused mostly by rupture of geological faults, but also by other events such as volcanic activity, landslides, mine blasts, and nuclear tests. An earthquake's point of initial rupture is called its focus or hypocenter. The epicenter is the point at ground level directly above the hypo-center.

Indonesia Tsunami

Mega disaster

Mega disaster

BANDA ACEH, INDONESIA—The facts area unit therefore surprising they bear continuance.
Just before eight a.m. time on Dec. 26, 2004, one amongst the most important earthquakes ever recorded occurred off the Indonesian island of Sumatra. It triggered a vast moving ridge, devastating shorelines round the ocean.
Aceh province, on the northern tip of Sumatra, was out and away the worst affected. Waves up to twenty metres high destroyed everything, taking homes, boats, trees and cars together.
Some 170,000 folks were killed. many thousands were cut and displaced.
Here in Aceh’s capital, survivors recall the day that worn out life as that they had well-known it.
