Introduction: A Webquest is a way for you to explore a topic and find useful information to help you understand the topic. In this webquest, you will be visiting web sites that will help you better understand the Earth's interior, how heat is transferred, continental drift, plate tectonics and how these topics fit together.
Task: This webquest will take you through a review of the Earth’s structure.When you come to an underlined link, click on it. The link will take you to another web site that will provide you with information on the section topic. After you read the entire web page, you will complete the questions which follow the link.
Directions:
To begin your webquest, click on the following link and copy it into you Google docs: Inside Earth Work Sheet
Once you have successfully copied the worksheet, add your last name to the beginning of the title of the document.
Finally, begin working on your worksheet using a combination of the resources on this page, as well as your book.
Part 1: Earth's InteriorEarth is many thousand kilometers in depth. If you could travel deep into the Earth's surface you would find it contains three main layers: the crust, the mantle and the core. To learn more about the layers of Earth, click on the following links and answer the questions that follow:
Click on the Volcano World link. After reading each slide click the "next" botton and proceed to read the next slide. When you have examined all of the slides, complete the questions on the "questions" slide.
Part 2: Convection Currents and the MantleHeat transfer is the movement of heat from a warmer object to a cooler object. There are three ways in which heat can be transferred: conduction, convection and radiation. Click on the links below and answer the questions that follow.
Test your knowledge! Scroll down to the bottom of the Heat Transfer web page and take the "Mini Quiz". As you already know, the Earth's mantle contains two layers: the asthenosphere (upper part of the mantle) and the lithosphere. Because of the intense pressure and temperature in the mantle, convection currents occur. To learn about what influences these convection currents have on Earth, read the web page below and answer the questions that follow:
Part 3: Drifting Continents The theory of Continental Drift originated with the German scientist Alfred Wegener. He proposed that there was once a super continent called Pangaea. Wegener proposed that over time, the continents drifted apart, but he couldn't show how this happened. Read through the following links to learn about Wegener's theory of Continental Drift.
Part 4: Sea-Floor SpreadingThe movement of plates caused by convection currents causes both constructive and destructive forces beneath the ocean floor. To learn more about this topic, click on the link below and answer the questions that follow:
Part 5: The Theory of Plate TectonicsThe Theory of Plate Tectonics was formulated in the 1960s and 1970s when new information became available about the Earth's interior. To learn more, click on the links below, read the web pages and answer the questions that follow.
Make sure that you've answered all of the web quest questions, neatly, using complete sentences which restate the question and with good grammar.
