The remains of ancient plants can provide a wealth of archaeological information about a site, with many methods being available to the archaeologist engaged in extracting this data. Perhaps one of the most widely-known of these techniques, possibly because of its attractive nature, is pollen analysis - a technique developed in the early years of the twentieth century by, like so many archaeological techniques, a geologist -- the Norwegian Lennart van Post. To understand the technique and the uses
Introduction When looking at the Earth, it becomes readily apparent that cycles are an important theme. Earth is a closed system. Meaning only energy can pass into and out of its atmosphere with the exception with few meteorites that enter and the manmade objects we eject. Earth has the water cycle, the carbon cycle, the nitrogen cycle, the rock cycles and Earth itself cycles around the sun. It is easily understandable then that Earth climate also undergone many cyclic changes from one extreme to
at the site. He also assumed that if bison today give birth in the spring then it would hold true in the past as well. Another way to determine the seasonality of a sit is to look at the remains of both plants and animals. Archeologist can use palynology (the study of fossilized pollen) to determine the season of a site because certain plants bloom at certain times of the year.

Extraterrestrials Can the Earth be the only place in the Universe that harbors life? Most astronomers don't believe this is true. Certain statistics in the Universe provide evidence that living beings may be common place through out the universe, on planets of other stars besides the sun. In this paper I plan to discuss the various viewpoints of those that believe that extraterrestrials exist and have even been visiting Earth, and the viewpoints of skpetics that believe that aliens don't exist
CHAPTER 2 LITERATURE REVIEW 2.0 Preface A million years ago, earth was frequently visited by terrestrial object and hit repeatedly. Impact from meteor believes to be the major cause of extinction of animal species such as dinosaur, landscape and climate change. Huge impact changes the whole environment with its process during and after the impact. Suitable geophysical methods used in order to understand better on impaction and its operation. Some of the impact sites too became commercial exploration
Bald Cypress (Taxodium distichum) is one of the most important and valuable timber species in the world due to its superior wood characteristics, durability, and ability to grow at high densities within inundated habitats. Bald cypress technically is not a true cypress such as those within the genus Cupressus. It is within the genus Taxodium, and family Cupressaceae (Bragg 2011). Bald Cypress is the state tree of the state of Louisiana, where the majority of the United States’ permanent swamps are
