Objectives
Name:
Date: Period

Explain _______________________________________________________________________.

Describe ______________________________________________________________________.

Identify _______________________________________________________________________.
Topographic Maps

One of the most widely used maps is called a topographic map, which
___________________________________________________________________________.

topography = the ________________________________________________features of a region

elevation the height of an object __________________________________________________
Advantages of Topographic Maps

Topographic maps provide __________________________________________________about the surface of Earth than other drawings.
Elevation on Topographic Maps

On topographic maps, ____________________is shown by using _________________________.

contour line = a line that connects __________________________________________on a map

The difference in elevation between one contour line and the next is called the
___________________________________.

The contour interval is selected based on the relief ____________________________________.

relief = the difference between the _____________________________________ in a given area

Every ____________________________________is darker than the four lines one either side of it. This ____________________________________makes reading elevation easier.
Landforms on Topographic Maps

The spacing and direction of contour lines indicate ____________________________________ represented on a topographic map.

____________________________________________________indicate that the slope is steep.

_____________________________________________ indicate that the land is relatively level.
PowerPoint 3.3 – Types of Maps

Landforms on Topographic Maps, continued

A contour line that bends to form a _____________________________________________.

The bend in the V points toward the ____________________________________; this V points upstream, or in the direction from which the water flows, if there is a stream.


Contour lines that form closed loops indicate a ____________________________________.
Closed loops that have ____________________________________perpendicular to the inside of the loop indicate a ____________________________________.

The diagram below shows how topographic maps represent landforms.
Quick Review

Why do V-shaped contour lines along a river point upstream?
Topographic Map Symbols

_________________________ are used to show certain features on topographic maps.

Symbol color indicates the type of feature.

___________________________________________, such as buildings, are shown in black.

_________________________are shown in red.

______________________________________are colored blue

_________________________ are colored green.

Contour lines are _________________________.

Index Contour, Contour Interval, and Relief
Soil Maps

Scientists construct soil maps to classify, map, and describe soils, _________________________
__________________________________________________.
Soil Surveys

A soil survey consists of three main parts: ___________________________________________.

The text includes general information about the _________________________,
_________________________, and _________________________of the area.


The tables describe the ____________________________________________of soils in the area.
The maps show the approximate __________________________________of the different soils.
Uses of Soil Maps

Soil maps are valuable tools for _________________________and
_________________________.


Soil maps are used by ____________________________________________________________.
The information in soil maps and soil surveys helps
_______________________________________ ___________identify ways to conserve and use soil and plan sites for future development.
Quick Review

Why do scientists create soil maps?

Other Types of Maps

Maps are useful to _______________________________________________.

Some Earth scientists use maps to show the location and ___________________________.

Other types of Earth scientists use maps to study ______________________________________.
