Relative dating activity worksheet
By doing this, you will unravel the geologic history recorded in the rock record, just as geologists did hundreds of years ago, and still do today. An earlier current-formed ripple set (at bottom of slide) was later modified by a second ripple train migrating at right angles to the first.Crests of the first set are preserved in the troughs of the second set, hence, the ladderback appearance.Although most attention in today's world focuses on dinosaurs and why they became extinct, the world of paleontology includes many other interesting organisms which tell us about Earth's past history.The study of fossils and the exploration of what they tell scientists about past climates and environments on Earth can be an interesting study for students of all ages.Moreover, we will focus in on the Greenhouse Effect and Global Warming and relate it to climate patterns.This topic looks at minerals and rocks and helps us to understand the different properties needed to identify them.The geologic time scale was initially developed by determining the relative ages of rock units, first in Europe, and then in other parts of the world. To determine which rock units were older and which ones were younger (in a relative sense), geologists devised a number of laws, or principles, to help figure out the sequence of geologic events in a particular locality.
PALEONTOLOGY, AND in particular the study of dinosaurs, is an exciting topic to people of all ages.The Physcial Setting: Earth Science can be a challanging course.Below are some additional resources to help you along the way, prepare you for your midterm exam and the Earth Science Regents exam.In this course you will be studying the different processes, relationships, mechanisms, and concepts that help us interpret our planet Earth.This topic will help you learn the basic skills of reading and interpreting maps.Teaching about Earth's history is a challenge for all teachers.Time factors of millions and billions of years is difficult even for adults to comprehend.Before you begin this activity, read the book chapter listed below, which is available online through Library Reserves.Electronic course reserves, or "e-Reserves," are articles and book chapters that are available online through the University Libraries.Moreover, this chapter will revisit sedimentary rocks and see how the sediments produced during weathering factor into the formation of the different rocks.In this topic we will learn about the beginnings of Earth.
