Ch 2: Scientific Models & Tools for Earth and Space Science

About This Chapter

Delve into the world of topographic maps, seismograms, quadratic models, LANDSAT and SEASAT satellite imaging, climate change models, and magnetic surveys. This chapter covers these scientific models and tools, plus more.

Scientific Models & Tools for Earth and Space Science: Chapter Summary

This chapter includes lessons on several types of scientific models, including physical, graphic, and mathematical models to help you boost your science knowledge. There are also numerous lessons explicating the various specialized maps involved in Earth and space science. You can review how scientists use GPS, GIS, remote sensing, and aerial photography technology in geographic studies. Once you have completed this chapter, you should be able to:

  • Understand how to interpret and use topographic and geologic maps
  • Identify the appropriate graphical model to display information, like 2-D visual representations, charts, or graphs
  • Analyze scientific models used to predict future events, such as hurricanes and tsunamis
  • Solve real world chemistry and physics problems by using the exponential growth, exponential decay, and quadratic models
  • Describe techniques that scientists use to study unreachable places, such as the interior of the Earth and the depths of the universe

Our lessons are written by experienced instructors. Learn from these carefully prepared lessons, which include multiple visual examples of maps, graphs, and charts depicting Earth and space science data, as well as step-by-step calculated equations for mathematical models. Viewing the lessons in video format will further allow you to interact with these materials.

Creating & Using Physical & Graphic Models in Science

1. Creating & Using Physical & Graphic Models in Science

The earth is enormous! Studying the earth can be overwhelming because of its size and scope, so models of it are made to make it easier to understand. In this lesson, we will explore physical and graphical models, including what they are used for and how they are made.

How Mathematical Models are Used in Science

2. How Mathematical Models are Used in Science

Do you ever wonder how scientists make predictions? Instead of a crystal ball, they actually use mathematical models! In this lesson, learn about how these models are used in science.

Alternative Models in Earth & Space Science

3. Alternative Models in Earth & Space Science

In order to investigate a scientific phenomena in the Earth and space sciences, it is important to propose alternative models. In this lesson, we list such models and discuss their appropriateness.

How Scientists Study Earth's Interior Structure

4. How Scientists Study Earth's Interior Structure

We can't see what Earth's interior is made of, but scientists are able to study it in other ways. In this video lesson, you will learn how seismic activity helps us understand and describe the inner layers of the earth.

Geography Tools: Maps, GPS & GIS

5. Geography Tools: Maps, GPS & GIS

How can we study the earth and the features in it? Watch this lesson to find out more about common tools used in geography, including maps, global positioning systems, and geographic information systems, and their differences.

Using Maps & Images to Identify Geographical Features

6. Using Maps & Images to Identify Geographical Features

There's a whole world that can be seen in maps and images, but only if you know how to read them. In this lesson, we'll examine this problem and see how people depict the natural world in different ways.

Using & Understanding Topographic Maps

7. Using & Understanding Topographic Maps

Topographic maps are useful because they help us understand and locate topographic features on Earth's surface. But in order to properly read a topographic map, you need to be able to interpret its lines, symbols, and shapes correctly.

Understanding & Interpreting a Geologic Map

8. Understanding & Interpreting a Geologic Map

Geologic maps are neat because they show us the location of features found underneath Earth's surface. But just like any other map, they have their own set of symbols and codes that we need to understand in order to properly interpret them.

Aerial Photography vs. Remote Sensing

9. Aerial Photography vs. Remote Sensing

In this lesson, we'll look at aerial photography and satellite imaging, both forms of remote sensing. In particular, we'll discuss some key features of each and how they are used.

Geophysical Surveys: Definition & Methods

10. Geophysical Surveys: Definition & Methods

Geophysical surveys are the methods used in archaeology to produce a detail image or map of an area. There are many different methodologies, but the most successful surveys involve a solid research design that is well planned.
