temperate zone may not be that tragic‚ but what about the consequences of a few degrees temperate increase closer to the equator where the average temperate is consistently high? A few degrees warmer in Europe‚ or Minnesota might not be too tragic‚ but residents near the equator would undoubtedly disagree. A temperature increase on the Sahara desert‚ or anywhere along the equator would have definite tragic results. Next the exuberant‚ expressive‚ and over-joyed professor Phillip Scott‚ when

the Gulf Stream is a warm ocean current in the North Atlantic flowing from the Gulf of Mexico‚ northeast along the U.S coast‚ and from there to the British Isles. The Gulf of Mexico has higher air temperatures than Britain as it is closer to the equator. This means that the air coming from the Gulf of Mexico to Britain is also warm. However‚ the air is also quite moist as it travels over the Atlantic ocean. This is one reason why Britain often receives wet weather. Surface ocean currents can

Introduction: The Trichoptera‚ or caddisflies‚ are an ecologically diverse order of insects. The adults resemble small moths and are terrestrial‚ while their larvae are aquatic and spin silk (Bongard 2004). It is due to their diverse designs in the secretion of silk threads that they are able to expand their ecological niches. The silk threads of the larvae are used to create shelters‚ nets‚ and cases- adopting an evolutionary system to exploit a wide range of resources (Vaughn 1985). There are about

seasons‚ animals‚ fires‚ spreading of diseases‚ and floods. The reason Africa is the best example of latitude is because the equator runs directly through the middle of Africa causing any climate changes to happen in both north and the south of the equator. Latitude has a major effect on the climate zones and amount of rain parts of Africa receive. The climate near the equator is tropical meaning it is hot and gets a lot of rain more than 180 days out of the year. The deserts in Africa are the most

If one examines the effects of the sun on skin color‚ one will notice that those individuals who live the closes to the equator have the darkest pigmentation and those that live further from the equator have lighter pigmentation. All these facts do not explain that any ethnic group is different in their anatomy. As evident as these facts tell us that race is a social construction‚ theses ideas still stain
