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

3.) List four facts that characterize the oceanic ridge system. Four facts that characterize the oceanic ridge system are: firstly‚ it represents 20 percent of Earth’s surface‚ the oceanic ridge system winds through all major ocean basin like the seams on a baseball. Ridges vary in width from 600 miles to 2500 miles. The mid-ocean ridge represents an area where‚ lithospheric plates move apart and new crust is created by magma pushing up from the mantle . Also‚ the mid-ocean ridge system is an example

GE 150 Survey of the Sciences Unit 1 Lab 1 In the experiment that I performed that was based on the Redi experiment on spontaneous generation‚ I first observed that there were several pieces of uncovered meat. There were maggots on the pieces of meat that appeared to be older. There were flies flying around and landing on the meat. The questions that I asked about what I saw were why were there maggots on the older meat‚ and did the maggots have any connection with the flies. I also wondered

Chapter 1 1.1 Earth Science & the Earth System -Earth science is the study of Earth and the processes that shape it -The earth system is composed of four principal components: atmosphere (air‚ weather)‚ hydrosphere (water‚ ice)‚ biosphere (plants‚ animals)‚ and geosphere (land‚ rocks). - Earth science can be broadly defined as the investigation of interactions among the four parts of the earth system. - The second largest earthquake ever recorded buckled the seafloor west of Sumatra‚ Indonesia

What is Earth Science? Earth Science - The study of the Earth and its neighbors in space. It is an exciting science with many interesting and practical applications. Some Earth scientists use their knowledge of the Earth to locate and develop energy and mineral resources. Others study the impact of human activity on Earth’s environment and design methods to protect the planet. Some use their knowledge about Earth processes such as volcanoes‚ earthquakes and hurricanes to plan communities that will

They will be mourned by their families and friends; they will be mourned by the nation; they will be mourned by the people of the world; they will be mourned by a Mother Earth that dared send two of her sons into the unknown. In their exploration‚ they stirred the people of the world to feel as one; in their sacrifice‚ they bind more tightly the brotherhood of man. In ancient days‚ men looked at the stars and saw their heroes in the constellations. In modern
