California’s San Joaquin Valley is one of the states top agricultural regions. It is 240 miles long and bordered by many mountain ranges. Eight counties compromise the San Joaquin Valley. Much of the problem in Americans most productive farm region is simply a function of its unusual geography and climate. Its bowl-like geography causes an entrapment of fog, air pollution and much of the horrible heat waves that are present during summer months.
Hurricanes need the ocean’s water temperature to be about 80 degrees to a depth of about 150 feet. Another factor of the forming of hurricanes is the rapid cooling of the warm water vapors that were evaporated, which causes condensation (the second step of the water cycle). The third step of the water cycle is precipitation and that happens when too many water vapors are condensed and rain starts to fall. Humidity is also needed in the
Explain how physical factors influence the distribution of biodiversity shown (10 marks) There are several factors influencing biodiversity including; isolation, age, altitudinal range, productivity The most bio diverse areas are between the tropic of cancer and the tropic of Capricorn. The Philippines, Indonesia and Malaysia have over 3000 plant species per 10000 km2 because they’re isolated as a series of islands which means there are more endemic species on the island as species develop in a more distinct way. The location within the tropics combined with the old age of the countries mean higher biodiversity as the species have more time to develop and evolve. Being within the tropics means there are fewer physical constraints such as light and water which are all in abundance due to rainforest conditions. The Himalayas have over 4000 plant species per 10000 km2 due to the large altitudinal range which means more climatic zones are involved creating more diverse habitats such as rock faces, steep hills.
Amazonian rainforests contain the biggest and most species-rich tract of tropical rainforest that there is to be found. It is the world's greatest natural resource - the most powerful and bio-actively diverse natural phenomenon on the planet. What exactly has happened? The main problem with the Amazonian rainforest is that it is being destroyed just like other rainforests around the world. The problem and the solution to rainforest destruction are both economic.
World Distribution Tropical forests are found near the equator in Central and South America, parts of Africa and Asia. They are hot and humid and contain a huge variety of plants and animals - around half of all the world's species. The trees are mostly hardwood. The climate is called equatorial. Average Temperature Rain forests belong to the tropical wet climate group.
The word savanna stems from an Amerind term for plains which became Hispanicize after the Spanish Conquest. It is a transitional biome between those dominated by forests and those dominated by grasses. The Savanna biome is associated with climates having seasonal precipitation accompanied with a seasonal drought. A multitude variant, the parkland, is located in the drier portions of the humid continental climate. Savannas have warm temperature year round.
Even the extensive evidence that high amounts of greenhouse gases do have an impact on the rising temperature many still think all of this is part of the Earth’s natural cycle. During the last century temperatures have increased on a global scale, known as global warming. There has been a sharp rise in average temperature being 0.7°C between 1900 and 200. Scientists believe that this rise in temperature is mainly due to human factors and the increase of industrialisation and the revolution. These industrial activities have raised atmospheric gases such as carbon dioxide which contribute to greenhouse gases.
TABLE OF CONTENTS INTRODUCTION Location of the Equatorial Rainforest Equatorial forests are located right above the equator and have very hot temperatures. The major Equatorial Rainforests are found in South and Central America, West Africa and Eastern Asia. • South and Central America – Amazon Rainforest • West Africa – Congo Rainforest • Eastern Asia - South Eastern Asia Rainforest • The Amazon is the largest rainforest in the world. The Congo is the second and the South East Asia the third. See Diagram 1.
After 1206 they established an enormous empire under Genghis Khan, linking western and eastern Eurasia. >(p. 325) monsoon Seasonal winds in the Indian Ocean caused by the differences in temperature between the rapidly heating and cooling landmasses of Africa and Asia and the slowly changing ocean waters. These strong and predictable winds have long been ridden across the open sea by sailors, and the large amounts of rainfall that they deposit on parts of India, Southeast Asia, and China allow for the cultivation of several crops a year.

Greenhouse gases are mostly comprised of carbon dioxide and methane. According to the Environmental Protection Agency (EPA), “greenhouse gas emissions caused by human activities have increased by 14 percent from 1990 to 2008” (Climate, 2010, slide3). In the last century, the carbon dioxide “concentration in the atmosphere has risen from 280 ppm [parts-per-million] to more than 380 ppm because of the industrial activities of humans” (Ruddiman, 2008, p. 86). We’ve had strong levels of carbon dioxide in the atmosphere in the past from volcanoes, but what does this really do to the environment? First off, it raises the temperature, and also the excess carbon dioxide that does not go into the atmosphere eventually gets dissolved in the oceans causing them to acidify.
