The final cause of droughts, is down to the human race, and their lifestyle demand for extra water to fulfil their needs, this puts extra pressure on supplies. The great Drought of China during 1876-1879 was one of the deadliest droughts in the worlds recorded history; no food at all could be grown on 386,000 square miles of farmland across nine provinces of northern China. Rivers were dry, so most crops and livestock died. An estimated nine million people died.

The first will be about Health and Safety at Graham School. The second will be about Health and Safety at Scarborough Sixth Form College and the last will be about Health and Safety at CP Kelco's Knowsley Plant. The aims of this report
Accidents in the places where scientists work are rare. This is because scientists must follow strict regulations and procedures. These are aimed, successfully are reducing the risk of harming or damaging themselves or people near to them in the workplace. Hazards and scientific place include: * Careless behaviour. * Not using equipment properly. * Not using protective and safety equipment. * Not following correct Health and Safety at Graham School Risk Assessments The risk assessments they have at Graham School and Scarborough Sixth Form are given have eleven headings.

Mallet did not know why this was and it was not until the 1960's that the puzzle was solved and scientists found an explanation. This became known as the theory of plate tectonics. ('Tectonic' is a Greek word that means 'building'). This theory says that the Earth's crust (or the lithosphere) is actually split into 20 or so moving pieces which fit together like a jig-saw. The chunks of moving earth are called tectonic plates; there are 7 huge plates: Pacific North American South American African Eurasian Indian Antarctic and about 12 smaller ones and they move at about the same rate as our fingernails grow.

Earthquake is a shaking of the ground caused by the sudden breaking and shifting of large sections of the earth's rocky outer shell.
Stresses in the earth cause large blocks of rock along a fault to strain, or bend. When the bending becomes too much, the rock breaks and snaps into a new position, causing the shaking of an earthquake. Earthquakes usually begin deep in the ground. The point in the earth where the rocks first break is called the focus, also known as the hypocentre, of the quake. The focus of most earthquakes lies less than 70 kilometres beneath the surface, though the deepest known focuses have been nearly 700 kilometres below the surface.

Helens and was at the time the British Ambassador to Spain. He had also named three other volcanoes in the cascades; Mounts Baker, Hood, and Rainier.

Disasters on this scale occurred annually throughout the 1980s, and the potential for such disasters is increasing. Human activity is implicated in the rising number of hazardous events. For example, the disastrous floods and landslides of November 1991, though triggered by intense rainstorms (typhoons), have been blamed primarily on logging on hill slopes. Hazard 1: Earthquake: California haza1 012.jpg One of the hazard California suffers from is earthquakes. They suffer from this because California lies on a conservative plate boundary.

4.2). Along a noncliffed shoreline (such as the Atlantic coasts of North America and Africa), the land usually slopes gently toward the sea. This gently sloping land, some of which may be above sea level and some below, is called the continental shelf or platform. At the edge of the continental shelf there is commonly a sharp drop-off to the steeper continental slope. At the bottom of the steep continental slope, the land begins to level off again. This more gently sloping land is called the continental rise; it marks the transition to the much flatter ocean floor, called the abyssal plain.
