Weather and Climate
The difference between weather and climate.
Weather describes the day to day conditions of the atmosphere
Climate is the average weather conditions found in an area and is based on weather patterns recorded over a long time
What does the bar graph show
Precipitation
Name the four layers of the rainfall
Emergent, Canopy, Understory, Forest floor
Poison dart Tree Frog
Bright colours to warn predators of their poison
What is deforesation?
The intentional clearing of forest land
Describe an equatorial climate
The weather is always warm and wet
What does the line graph show
Temperature
Which layer of the rainforest gets the most sunlight?
The emergent layer.
Three-Toed Sloth
Hooked claws and long arms to hand easily from trees.
Slow metabolism so need very little food
Name and describe one cause of deforestation in the Amazon.
Cattle ranching, logging, slash and burn, mining, HEP, settlement
Describe the climate in the Amazon.
Hot and humid climates where it rains nearly everyday.
An indigenous tribe who live in the Amazon Rainforest
The bottom layer of the rainforest
The understory
Something that has changed or changes to become suitable to a new or special situation
What is an adaptation?
Tribes might be evicted from their homes
Human impact of deforestation
Why is the Equatorial Climate so Wet?
The sun heats the Earth and the air above it.
As the air heats up, it begins to rise
As it rises the air begins to cool and it condenses to form clouds. This is called condensation.
Water droplets form and fall to earth as rain in heavy thunderstorms
This is known as convectional rainfall
Consequence of deforestation
An impact
The layer with the most biodiversity
The canopy
Large wide roots of trees to support the huge trees which grow from them
Buttress roots
Cutting down older trees rather than all the trees in one area
Selective logging - solution to deforestation
Why is the Equatorial Climate so hot?
Places near the equator are warmer than places which are further away from the equator.
This is because the surface of the Earth isn't heated evenly (places at the equator are heated more than those at the poles).
At the equator the heat from the sun is spread out over a smaller area, so the suns heat is more concentrated
At the poles the heat is spread out over a larger area so there is little heating.
The replanting of trees in a deforested area
Afforestation
Selected areas of the rainforest have been declared as _________ to protect the rainforest with laws and reduce hard caused by deforestation
National Park
Holes in leaves of the plant help rain fall through the hole, so the leaf isn't weighed down, helping it survive it's climate
Swiss Cheese Plant
The largest city in the Amazon region
Manaus
