AGE OF THE EARTH Scientists have settled on the age of the earth of about 4.6 billion years as a result of research started almost 50 years ago. This conclusion was based upon carefully designed and conducted experiments that compared the ratios in rock samples of parent elements to daughter elements ( some of which would have been from radioactive decay of the parent‚ some of which may have been present in the sample at the time of formation). Since radioactive decay is known to occur at a constant

Dynamic Earth Has the Earth been static since the beginning of time? Well‚ Earth hasn’t been moving vigorously but it is changing at a steady rate. New geological features‚ rock formations‚ and locations of plates all rise and demolish some in a lifetime and others over a span of millions of years. Earth is dynamic; it constantly progresses and doesn’t rest. Through the churns and molds‚ the twists and turns‚ Earth is active because of plate tectonics and the rock cycle. The ideas

Creation of the Earth from the Yuchi people and The Iroquois Creation Story from the Iroquois people show slightly different worldviews‚ yet both stories opinion of creation have the element of earth being built‚ created‚ as their titles each allude to. These stories worldviews are more alike than not because they each build from the view that earth’s creations come from a higher being or savior. The savior in each story consciously altered what already naturally existed of earth at that time. This

1. Summarize advances over time in determining the age of the Earth‚ including the importance of the discovery or radioactivity. Herodotus counted layers of earth near the Nile River in 450 B.C.E. The Bible was used in the Middle Ages to compute the age of the Earth. The 18th and 19th centuries brought a more scientific look into determining the age of the Earth by studying the salinities of the oceans‚ the rates of sedimentation‚ and models of cooling of different materials in order to calculate

Atmosphere Homework Describe the composition of the air Air is a mixture of gases and aerosols that compose the atmosphere surrounding Earth. The primary gases of air include nitrogen (78%) and oxygen (21%). Trace gases and aerosols make up the remaining 1% of air. The trace gases include the noble gases argon‚ neon‚ helium‚ krypton and xenon‚ hydrogen and the greenhouse gases. The aerosols are solid or liquid particles having diameters in the region of 0.001 to 10 microns‚ and include dust

Earth Summit International meetings aiming at drawing up measures for the environmental protection of the world. The first summit took place in Rio de Janeiro‚ Brazil‚ in June 1992. Treaties were made to combat global warming and protect biodiversity (the latter was not signed by the USA). The second Earth Summit was held in New York in June 1997 to review progress. The meeting agreed to work towards a global forest convention with the aim of halting the destruction of tropical and old-growth forests

An Analysis of Religions on Earth: Are Earth People Religious? Donna FalkenburgREL212 Living Religions Professor Charles Hall 5/5/13 I was sent to Earth to determine if Earth people are religious. During my time on Earth‚ I have observed that many of Earth’s people are religious and although there are many different types of religions‚ they show three different behaviors that are shown in many religions. The criteria I used to see if Earth’s people were religious or not were whether or not

There are many different layers within the Earth. The core is at center of the Earth. The Earth’s core takes up sixteen percent of Earth’s volume‚ containing thirty-three percent of its Mass ..Pressure rises steadily inside the earth because of the weight of overlying rock. Therefore ‚the Pressure at the outer boundary of the core reaches 1.37 million atmospheres‚ 3.7 million Atmospheres. The core is made mostly of iron and nickel and possibly smaller amounts of lighter elements including sulfur

most admired. His intelligence‚ wit‚ and morals of the day allow the Greeks to look up to him as a role model. Perhaps the greatest characteristic that separates Odysseus from the suitors and his fellow shipmates is the wit and ability to trust the gods with their advice. The Odyssey begins 10 years after the Iliad had left off and Odysseus is trapped on an island with Calypso. Odysseus then has many hardships upon which he overcomes through his intelligence and wit. One of the first obstacles
