Earth Science is an all-embracing term for the sciences related to the planet Earth. It is arguably a special case in planetary science‚ the Earth being the only known life-bearing planet. There are both reductionist and holistic approaches to Earth sciences. The formal discipline of Earth sciences may include the study of the atmosphere‚ hydrosphere‚ oceans and biosphere‚ as well as the solid earth. Typically‚ Earth scientists will use tools from physics‚ chemistry‚ biology‚ chronology and mathematics

PLANET OUR HOME” God create our planet earth for us to have a home so we have to take care of our planet because God gave it to us and if we don’t take care of our planet someday our planet earth will be destroy or it will be gone. We have to protect our nature specially the trees because if we don’t protect our nature and if we cut down all the trees we will experience stronger floods and typhoon that will destroy our planet. We can save our planet earth by simply throwing your garbage in the right

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

“EARTH HISTORY” Geologic Time: Geology needs a time Scale: -The prime goal of the science of geology‚ is to interpreting earth history. Geological time scale- -Anordered‚internallyconsistent‚ internationally recognized sequence of time intervals‚ and record the life of Earth. Short history of geology: James Ussher(mid 1600s)- he determined that earth was only a few thousands of years old having been created in 4004 b.c Catastrophists(17-18cen.)-believed that earth landscape had been developed

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

Elaina Samelo 5th Block Ritzus The Good Earth The Good Earth‚ written by Pearl S. Buck‚ is a book about the political and social struggles of China. Since this book was published in 1931‚ the somewhat old-fashioned style of writing reveals the era of which it was written. Although it is apparent through the writing that this book is a little older‚ it has a charm that only older books can possess. It is one of the things that actually kept my attention; the old-fashioned charm. The publishing

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

August 8‚ 2013 Peopling of the Earth The earliest full human species known today lived in East Africa about 2.5 million years ago. Early humans survived by hunting and gathering. With an economy based on hunting and gathering‚ there is a great deal of space needed for just a small community. Before migrating majorly‚ they migrated to the Levant‚ in about 25‚000 years ago a global freeze happened and it wiped them out completely. They would then later end up migrating to the Middle East from Africa
