Darrell M. Bell Mrs. Felicia Curry English IV 1/3/12 Tornadoes are also popularly called twisters or cyclones and are characterized by rapidly rotating columns of air hanging from cumulonimbus clouds. (1) They are generally observed as tube- or funnel-shaped clouds. At ground level they usually leave a path of destruction only about 50 m (170 ft) wide and travel an average of only about 8 to 24 km (5 to 15 mi). Contact with the ground is often of an intermittent nature lasting for a period

Comprehensively analyse how the operation of TWO INTERACTING processes have helped shape the Tongariro Volcanic Centre. The Tongariro volcanic centre (TVC) has been shaped by the interaction of several natural processes. Some processes originate beneath the surface of the earth and have resulted in the building up of volcanic landscapes. However‚ climate processes operate on the surface‚ wearing down and shaping landforms. Volcanism is a process that operates beneath the earth’s surface. It

well suited to their habitat. Year round‚ the rainforest has a low diurnal and annual temperature range and a high average annual rainfall (approximately 2000mm a year). The warm‚ moist and unstable air is forced to rise at the inter-tropical convergence zone‚ resulting in daily convectional storms that contribute to the rainfall each year. As a result of this high rainfall the Amazon River seasonally floods‚ creating seasonally flooded

Hurricane Katrina: Development and Devastation Hurricane Katrina was one of the strongest storm systems to ever collide with the coastal United States in the last century. Strong winds sustained during landfall of over 140 mph combined with a very low central pressure (920 mb) to wreak havoc on many coastal communities in ways not seen before in the US (1). Despite monitoring the storms development‚ tracking its movement‚ and issuing early warnings‚ Hurricane Katrina has proved to be the most

Hence climate is the main soil forming factor that could possibly make any distinguishable characteristic change to soil properties between the regions. Climate‚ as both temperature and rainfall‚ has major effects on organic matter‚ chemical composition‚ base saturation and contents of carbonates and soluble salts (Young‚ 1976). The tropics of Australia consistently experience warmer annual temperatures. Warm temperatures coupled with high

meteotsunamis associated with the most intense tropical systems. At least five processes can be involved in altering tide levels during storms: the pressure effect‚ the direct wind effect‚ the effect of the Earth’s rotation‚ the effect of waves‚ and the rainfall effect.[10] The pressure effects of a tropical cyclone will cause the water level in the open ocean to rise in regions of low atmospheric pressure and fall in regions of high atmospheric pressure. The rising water level will counteract the low atmospheric

Section A - Restless Earth The earth’s structure At the centre of the earth is the core. Surrounding that is a mass of molten rock called the mantle. The thin layer on the outside is called the crust. There are two types of crust‚ continental and oceanic. The crust is made up of seven major plates and many smaller ones. The plates move due to convection currents rising in the mantle. Distribution of earthquakes and volcanoes Mainly found along plate boundaries. In
