Mapping the Earth: An Esri Lab Activity Answer Key
Mapping the Earth is an Esri lab activity that introduces students to the basics of cartography. The activity includes exercises on Earth’s topography and features, latitude and longitude, map projections, scale and distance, and creating a map.
Earth’s Topography and Features, Mapping the earth an esrt lab activity answer key
The Earth’s surface is made up of a variety of features, including mountains, valleys, oceans, and deserts. These features are represented on a map using different symbols and colors. For example, mountains are typically represented by brown or green triangles, while oceans are represented by blue.
The scale of the map determines the level of detail that can be shown.
Latitude and Longitude
Latitude and longitude are two imaginary lines that are used to locate points on Earth. Latitude is measured in degrees north or south of the equator, while longitude is measured in degrees east or west of the prime meridian. The latitude and longitude of a point can be used to find its location on a map.
Map Projections
A map projection is a way of representing the Earth’s surface on a flat surface. There are many different types of map projections, each with its own advantages and disadvantages. The most common map projections include the Mercator projection and the Robinson projection.
Scale and Distance
The scale of a map is the ratio of the distance on the map to the distance on the ground. The scale is usually expressed as a fraction, such as 1:24,000. This means that one unit on the map represents 24,000 units on the ground.
Creating a Map
To create a map, you will need to choose a map projection, set a scale, and label the features. You can also use symbols and legends to convey information on the map.
Essential FAQs: Mapping The Earth An Esrt Lab Activity Answer Key
What is the purpose of a map projection?
A map projection is a systematic transformation of the Earth’s surface onto a flat plane. It allows cartographers to represent the three-dimensional Earth on a two-dimensional surface while preserving certain properties, such as shape, area, or distance.
How do I calculate the distance between two points on a map?
To calculate the distance between two points on a map, use the map scale. The scale indicates the ratio between the distance on the map and the corresponding distance on the ground. Measure the distance between the points on the map and multiply it by the scale to obtain the actual distance.
