EARTH’S HISTORY Academic Standard 8-2 Study Guide 8-2.1 Explain how biological adaptations of populations enhance their survival in a particular environment There are variations among species of similar populations. Organisms of a species differ from one another in many of their traits. A trait that helps an organism survive and reproduce is an adaptation. Species in a particular environment that are better adapted to living conditions there and are therefore able to meet their survival

Earth Day Some people who talk about the environment talk about it as though it involved only a question of clean air and clean water. The environment involves the whole broad spectrum of man’s relationship to all other living creatures‚ including other human beings. It involves the environment in its broadest and deepest sense. It involves the environment of the ghetto which is the worst environment‚ where the worst pollution‚ the worst noise‚ the worst housing‚ the worst situation in this country

There should be a balance in order for most living things to survive. A stable environment is the key to survival. Through-out many years‚ things Earths systems have been changing drastically. The outcomes of change can be good or bad. The Earth is warming faster than ever before‚ and humans are to blame. Ever since the industrial revolution‚ (which began during the mid-1800s) humans had affected the Earth’s atmosphere drastically. We have quickly attained a mass amount of geological force in terms

49 Simple Things You Can Do to Save the Earth (The author wishes to thank his wife for suggesting he "get up and do something" to save the earth. This book is dedicated to her.) 1. TURN OFF THE LIGHTS. Even if you’re only going out of the room for a few minutes. Those kilowatts add up. (My wife groans when I say it‚ but‚ "It makes cents—with a c.") 2. UNPLUG APPLIANCES WHEN NOT IN USE. Some of them‚ with their complicated timers and instant start-up features‚ constantly consume small amounts

rocks--is that it began as part of Earth but was blown off when the early Earth was struck by a Mars-sized early planet (retroactively named Theia). Huge amounts of debris were ejected into orbit around the Earth‚ where most of it coalesced into the Moon. The other moons in the solar system have different origins. The small ones are mostly captured asteroids‚ I think‚ while many of the larger ones (e.g. Ganymede) are thought to have formed in orbit around their respective planets. How are comets different

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

A look at the Inner Earth Studying the earth’s interior can help us to understand earthquakes‚ volcanoes‚ plate tectonics and more about the inner earth’s natural processes. In general the earth’s interior has been sorted by Gravity. Heavier elements like iron tend to sink toward the center or core of the earth. Lighter materials‚ the silicates‚ oxygen compounds and water have risen to become part of the crust. This action has created distinct layers within the earth and is still in process today
