About This Chapter
Scientific Tools Used in Earth & Space Science - Chapter Summary
This chapter contains lessons on the methods and tools used in earth and space science, including how to read topographic and geologic maps, use geographic coordinates, and construct a scale map. Our expert instructors also discuss the Geographic Information System, computer modeling, and types of telescopes. Once you have completed all these lessons, you should be able to do the following:
- Differentiate between latitude, longitude, and elevation
- Understand how to interpret a scale map
- Identify the key concepts of refracting and reflecting telescopes
- Explain the different kinds of reflecting telescopes
- Discuss radio telescopes and interferometry
- Understand types of computer modeling used in earth and space science
- List types of scientific measurement instruments and their uses
The lessons in this chapter are taught by professional instructors who have created these fun an engaging videos that are designed to help you learn when it is convenient for you. The short videos and text lessons are available online at any time, and you can watch them in any order you want. Check your understanding by using the lesson and chapter quizzes.
1. How to Read Topographic and Geologic Maps
This lesson explains the main features of topographic maps, including contour lines, index contours and contour intervals. It will also cover two rules that all contours follow and discuss geologic maps and the information they contain.
2. Geographic Coordinates: Latitude, Longitude & Elevation
This lesson will seek to explain the geographic coordinate system. In doing so, it will explain latitude and longitude. It will also highlight the equator, the prime meridian, and the concept of elevation.
3. How to Construct and Interpret a Scale Map
This lesson will explain what a scale map is and how it represents two different things on the map expressed as a ratio. This lesson will also demonstrate the steps needed to create a scale map from any ordinary map.
4. Geographic Information System (GIS): Using Maps & Locations to Make Decisions
A Geographic Information System uses smart maps to describe geographical relationships. Learn how organizations use spatial analysis to improve decision making.
5. Types of Telescopes: Radio, Reflecting & Refracting Telescopes
Learn about the different types of telescopes that astronomers use: X-ray, radio, gamma ray, reflecting and refracting. Learn what the differences are between them and what different things they show us about the universe.
6. Refracting & Reflecting Telescopes: Key Concepts
This lesson will discuss some key terms and concepts relating to the refracting and reflecting telescope: primary mirror/lens, eyepiece, focal length, focal point, chromatic aberration, and achromatic lens.
7. Different Kinds of Traditional Reflecting Telescopes
This lesson will discuss three major kinds of traditional reflecting telescopes and their major differences. These include the Newtonian, Cassegrain, and Schmidt-Cassegrain telescopes.
8. Radio Telescopes & Interferometry
This lesson will go over some key concepts related to radio astronomy. We'll cover what radio telescopes are, the basics of how they function, and what their disadvantages are compared to optical telescopes and how this is resolved.
9. Computer Modeling in Earth & Space Science
What is a computer model? Learn how they are used in earth and space science to try to save lives and understand the past, then test your knowledge with a quiz.
10. Scientific Measurement Instruments: Types & Uses
There are many valuable measuring devices in science. This lesson will highlight how to use three such precision instruments: Vernier calipers, screw gauges, and physical balances.
