PPT-Unit 1 - Earth Systems and Resources

Geological Time Scale AIM How have stratigraphy and radiometric dating been used to construct the geological time scale The History of Earth Earths history has been studied through 2 methods. People use natural resources as raw materials to manufacture or create a range of modern conven iences Water and food provide humans with sustenance and energy for example and fossil fuels generate heat as well as energy for trans portation and indu Dotty Woodson.

Tilted on an axis (N-S pole) 23.5 degrees. Earth moves in space two major ways. Rotation. - spinning of Earth on its axis. West to East, 15 degrees per hour or once per day, counterclockwise. This causes day and night—half the Earth is always lit and have it always dark. Earth, Moon, and Sun Gravity and Motion Isaac Newton was the first scientist to explain what keeps the Earth and Moon in orbit Force – a push or a pull There is a force acting between the Earth and the moon that keeps them in orbit Leading TV Unit Manufacturer in Pune Innovative Designs, Superior Quality at Adeetya's Kitchen & Furniture https://adeetyas.com/tv-unit-manufacturers-in-pune.php
