Hazard-Wise: Classroom Resources for Teachers on Natural Hazards & Disasters

DIANE Publishing, 1995 - 112页
Provides the teachers with a ready-to-use classroom resource which covers many aspects of major national hazards and disasters. Through a series of exercises, students are stimulated to investigate the causes and effects of hazards and the way in which people can respond effectively to them. Well-know Australian case studies are used to illustrate the impact of natural disasters. Each section also contains activities designed to arouse greater interest in the topic such as crossword puzzles, research activities, and role-play exercises.

第101页 - At a destructive margin one plate dives beneath the other. Friction causes it to melt and become molten magma. The magma forces its way up to the surface to form a volcano to the side of the actual plate margin (the ocean trench).
第53页 - The dotted arrows show the direction the trade winds would take if the earth's rotation did not deflect them to the left in the southern hemisphere and to the right in the northern.
第28页 - FLOOD-PLAIN A plain, bordering a river, which has been formed from deposits of sediment carried down by the river. When a river rises and overflows its banks, the water spreads over the flood-plain; a layer of sediment is deposited at each flood, so that the flood-plain gradually rises.
第101页 - At a constructive margin where two plates are moving apart new magma can reach the surface through the gap. Volcanoes forming along this crack create a submarine mountain range called an ocean ridge, eg Mid-Atlantic ridge.
第101页 - In places where a plate is particularly thin magma may be able to escape to the surface. Such a place is called a 'hot spot'.

第28页 - PRECIPITATION In meteorology, the deposits of water, in either liquid or solid form, which reach the earth from the atmosphere. It therefore includes not only rain, but also sleet, snow, and hail, which fall from the clouds, and dew and hoar frost. The total depth of liquid deposited — the solid forms being melted — is measured at meteorological and climatological stations by means of a Rain Gauge, and expressed in millimetres...
第53页 - Air, in the form of wind, moves from areas of high pressure to areas of low pressure. • The speed of the wind depends on the difference in air pressure between two points.
