What’s on a map?
Maps have a lot of information. You need to know how to read them.
There are several parts to a map which explain details and help you really see where you are and where you're going.
Parts of a map
Legend Compass Rose Cardinal Directions Scale
Legend Help you decode
the symbols used on a map.
Also called a key.
The “clues” on this map include symbols for parts of a fairground.
Compass Rose
The compass rose shows the cardinal directions on a map: north, south, east, and west.
Scale
The scale helps you measure the distance between two places. When you know the distance you can calculate how long the trip will take.
Types of MapsSome Types of Maps are:
Political –shows boundaries, states, countries, that are man made
Reference Physical –shows natural features, i.e.,
water, landforms, etc. Historical Economic Road map
World Map The 7 large land areas are the
continents. (North America, South America, Africa, Europe, Asia, Australia, and Antarctica)
The 4 largest bodies of water are the oceans. (Pacific, Arctic, Atlantic, Indian)
LocationLocation and distance are stated using a system known as latitude and longitude.
Two Types:absolute location for a place is the exact spot on the earth’s surface where a place is found. The line of latitude is always read first followed by the line of longitude.
Relative location:
Parallels measure a location’s distance N or S. of the equator and run from E to W.
Latitude is measured in degrees from 0 to 90. Famous line of latitude is the equator and it is
0 degrees. It runs around the center of the earth and divides the earth in half.
Latitude
Longitude
Meridians measure a location’s distance E or W of the prime meridian and run from N to S.
Longitude is measured in degrees from 0 to 180.
Famous line of longitude is the Prime Meridian and it is 0 degrees. It runs around the center of the earth through Greenwich, England and divides the earth in half.
Unit 1: Louisiana’s Physical and Cultural Geography
Time Zones Earth has 24 time zones. United States has six. Pacific, Mountain, Central and Eastern
are the four time zones in the contiguous (connected) United States.
The earth rotates on its axis once every 24 hours. For this reason, the earth is divided into 24 standard time zones, one time zone for each hour in the day.
The earth rotates towards the east, which means that if you cross into the next time zone to the east, it is one hour later. If you cross into the next time zone in the west, it is one hour earlier.
The International Date Line plays an important role in time zones. It is located at 180 degrees longitude.
If you are standing on the east side of the International Date Line it is one day (Monday); however, on the west side, it is a day ahead (Tuesday)
LA is in the central time zone.

A Geologic History All Its Own
Geology: The study of how the earth was formed
Pangaea: 250 million years ago, the world’s landmass was one giant continent.
Pangaea was also known as “All Land.” At end of Paleozoic Era, Pangaea began
breaking apart, and the continents drifted away from one another.
Ocean formed between continents; Gulf of Mexico formed.
Pangaea
Gulf Coastal Plain During the Ice Age, much of the world’s water was trapped
in glaciers. Ocean levels were about 400 feet lower than today. The glaciers froze and melted several times. As the glaciers melted, the Mississippi River flooded the
Louisiana coastline. Mississippi River deposited sediment into the Gulf of
Mexico, filling in part of it. Sediment: suspended particles of dirt and sand carried by
rivers Coastal plains developed. Coastal plain: relatively low flat region built up by river
sediment Continental shelf: the edge of landmass where the Gulf’s
floor drops off into very deep water The Gulf Coastal Plain is formed of layers of river sediment. Louisiana is the only state that lies entirely on the Gulf
Coastal Plain.

Lesson 2Rivers and Coastal Erosion Objectives
Appreciate the geography of Louisiana Identify problems/ propose solutions for
Louisiana’s wetlands and coast Understand the impact of natural disasters on
Louisiana and the effects of them
Rivers Rivers’ sediment creates the land. Rivers’ movement shapes the land.
Floodplains A floodplain is a low flat valley with swamps,
lakes and deciduous trees. It also serves as a reservoir to hold excess water when the river floods. Deltas
Formed when a river flows into an ocean Mississippi Delta: where the river enters the
Gulf of Mexico
Coastal Marshes
Wet grasslands formed by river sediment deposited along the coast
Freshwater, saltwater, or brackish (mixture) depending on nearness to the ocean
Coastal Erosion One of Louisiana’s biggest ecological problems More than 35 square miles of land is lost each
year.
Going…Going…Gone? Causes of Coastal Erosion
As the river abandons its original delta, sediment no longer rebuilds the coastline.
Pounding waves and severe storms accelerate erosion.
Global warming causes ocean levels to rise, which causes coastal marshes to disappear.
Levee systems force sediment into the deep waters of the Gulf, where it cannot settle and rebuild the coastlines.
Coastal Area At Risk
Human InterferenceDamaging Practices Dammed rivers create reservoirs that trap the
sediment that would otherwise refresh the marshland.
The search for oil involves the construction of pipelines and canals that allow saltwater intrusion, which kills the marsh grasses that hold soil in place.
Marshlands may sink because of vast holes created by underground drilling for oil and/or salt.
Preservation Measures Grasses are being planted to keep soil intact. Sand is pumped onto barrier islands to reinforce
them. Caernarvon Diversion Project and Davis Pond
Freshwater Diversion
What are wetlands?
Wetlands- swamps, marsh, and other areas that have a natural supply of water and are covered
or soaked with water at least part of the year.
Uses of LA’s wetlands Recreational opportunities Thriving habitats Wildlife pantry Water filter (maintains water quality) Storm buffer/controls flooding Economic resource
Unit 1: Louisiana’s Physical and Cultural Geography
Problems facing LA Wetlands
Coastal Erosion
Flooding
Natural Causes: subsidence, wave erosion, salt water intrusion, sea level rising, tropical storms/hurricanes
Human Causes: because of our ever-increasing population, humans have eliminated or converted millions of acres of wetlands for other uses. We drain wetlands to create more land for agriculture and urban development.
Louisiana’s wetlands are disappearing at a rate of one football field EVERY 30 MINUTES
Louisiana animals are losing their habitat.
What can we do to help? Get Involved! Save Water (reduced amount of water going
through sewage treatment plants) Dispose of household products, pesticides, and
other chemicals carefully Help to control soil erosion (reduce hard surfaces
around your home) Recycle your Christmas Trees! Conservation Regulate Use Restoration Projects
(EX: replanting marsh grasses)
Closure Lesson 2Can students describe and analyze the distinguishing physical and/or human characteristics of Louisiana regions? Can students describe ways in which location and physical features have influenced historical events in Louisiana and the development of the state? Can students explain how or why specific regions are changing as a result of physical phenomena? Can students identify and describe factors that cause a Louisiana region to change?
Lesson 3Louisiana’s Natural
Resources
Appreciate the natural resources found in Louisiana
Identify Louisiana’s natural resources and locate them on a map
Salt Domes Ancient seas dried up, leaving a layer of salt
and other minerals exposed on the ocean floor.
Famous Salt DomesThe Five Islands
Jefferson Island Avery Island Weeks Island Cote Blanche Belle Isle
Louisiana’s Natural Resources
Mississippi delta is rich with natural resources.
Sulphur
Closely associated with salt domes Used to make acids, fertilizer, rubber, paper, and
other products One of Louisiana’s important minerals
Oil Oil production has been the most important part of our
economy for many years.
Coal Created when organic material is compressed by layers of
sediment
Physical and Cultural Geography
Geography: the study of places, their locations, and their physical and human characteristics
Physical geography: the study of landforms, oceans, weather, and climate
Cultural geography: the study of how people have interacted with, changed, and adapted to different places on the earth
Louisiana’s physical geography has shaped its cultural
geography.
Geographic Location
Resembles a boot Florida Parishes stretch from Baton Rouge to
Hammond to Bogalusa Of the 50 states, LA ranks 31st in size 3,600 square miles of water (1/4 of the state is
wet)
Boundaries
