On Friday, you will have your Rivers
and Deserts test. It will be a combination of MC, short answer,
world maps and long answer questions.
Rivers - You are responsible for understanding the theme of Interrelationships – How rivers affect humans, and how human activity affects river ecosystems.
Rivers - You are responsible for understanding the theme of Interrelationships – How rivers affect humans, and how human activity affects river ecosystems.
Ex. Deforestation of the
Amazon rainforest causes massive soil erosion and siltation of the Amazon
river. This makes it difficult for
species in the river to survive….
·
The life stages of a river –
youthful, mature, old age
·
Why rivers are considered important
and even sacred
·
At least three uses of rivers (other
than serving as a fresh water source)
·
The importance of river deltas, the
notion of alluvium (soil fertility
from rivers)
·
Case Study - Ganges - sacred river,
Colorado, river at risk
·
Find the following on a map - Ganges,
Nile, Colorado, St. Lawrence, Mara, Mekong
·
ISSUE - The advantages and
disadvantages of hydropower and large scale dams (Chapter 43) Block 2,
you received this as a photocopied booklet
You are
not responsible for knowing all of
the river features (ex. meander, saltation, etc.) but you may end up using
these terms in your written responses.
Deserts (Ch. 16)- You are responsible
for:
·
The main forms of erosion in a desert
(water - flash floods, wind)
·
What is a desert (definition)
·
Types of desert - hot vs. cold; sandy
vs. rocky
·
Vegetation types that you would see
in a desert (sparse vegetation)
·
Causes of desert (latitude,
rainshadow, cold ocean currents
·
Features - explain how a sand dune or
oasis is created
·
Loess - nutrients found in deserts +
soil fertility
·
Label deserts on a world map -
Sahara, Gobi, Australian, Atacama, Kalahari, Patagonian, Arabian
Soil Degradation & Desertification (Chapter 36 & 37)
- Block 2, you received this as a photocopied booklet
·
Causes of Desertification -
·
Be able to identify areas that are at
risk of desertification on a map and name them – Chapter 37 – ex. Sahel, China,
etc.
·
Effects of Desertification on land
and humans
·
Be able to explain specific human
activity that causes soil to deplete and become poor quality (ex. excessive use
of pesticides and fertilizers, overcultivation, overgrazing of cattle, etc.)
·
Be able to describe what healthy soil
looks like
·
Explain possible solutions to desertification
– be able to articulate the difference between preventing wind and water
erosion. You should be able to recognize diagrams/images of these solutions, and
draw them if necessary.
Key Terms
for Soil Degradation that may be new to you:
·
Overcultivation, Over-grazing, irrigation,
deforestation, shelter belts, ‘ploughing against the wind’, stubble mulching, terracing
