7th Grade

We are working on Chapter 11. I am posting Section 2 notes below. Today in class we worked on a Climate map. The students were to complete the map for homework if they did not get it completed in class. We will be testing on Thursday of next week over Chapter 11.

Climate and Vegetation
Chapter 11
Section 2

What Influences Climate?
Distance from the Equator

Runs through the midsection of Africa
Tropics also run through Africa
Much of Africa has a tropical climate
Influences not only climate, but also seasons

Role of Elevation
Higher the elevation- colder the temperature
Irrigate- supply with water from another source
Drought-long period with little or no rain
Oasis- a fertile place in the desert with water and vegetation

Unpredictable Rainfall
Because of Africa’s size, rainfall varies from region to region
West Coast and Central Africa get a lot
North and South get very little

Vegetation Regions of Africa
Tropical Rain Forests
Covers close to 20% of Africa
Lush vegetation and variety of wildlife
Farming, Fishing, Hunting, Logging
Tropical Savannas
2 seasons- dry and wet
Tall grasses and scattered trees
Large pack animals
Farming(wet season) Trade(dry season)
Desert Living
Nomads- people who have no permanent home
They follow trade routes or migrating animals
Live up in the mountain regions during rainy season and around oases during dry seasons
Make a living trading, herding, or caravan leaders

Climate & Health

Sleeping Sickness
Tsetse Fly- found in 1/5 of Africa
A bite can kill a cow
A bite to a human causes “sleeping sickness”

Malaria
Spread by mosquitoes
Moist climates- breed in swamps or standing water
