Presentation on theme: "Rainforests – true or false?"— Presentation transcript:

1 Rainforests – true or false?
1 The natural vegetation of all the land on the equator is rainforest 2 The rainforests contain examples of over ½ the world’s species of plants and animals 3 The climate of rainforests can be described as ‘hot, wet and humid all year’ 4 Temperatures fall rapidly at night time 5 The average temperature all year is above 35°C 6 Rainforests have about 750mm of rain a year 7 It rains every day at around 10 a.m. 8 The main rainfall type is convectional rainfall 9 Rainforest soils tend to be poor and infertile 10 There are 4 distinct layers of vegetation in the rainforest ecosystem

2 Today's Objectives To locate and map the world’s rainforests
To describe rainforest climate and weather To explain adaptations of vegetation in the rainforest to the climate

3 Objectives By the end of the lesson, you should be able to… … describe the location, climate, weather and vegetation layers of rainforests

4 Where is the Amazon? Amazon

5 Equatorial climate world locations
Amazon Basin 5°N 5°S Equator 0° It is mainly found between latitudes 5°N and 5°S of the Equator It is found in the Amazon basin in South America and in the Zaire basin in Africa

6 Amazon Location map Page 8-9 old book pages 10-11 new
Shade the areas where rainforest is located from Diagram D Label ONLY the Amazon rainforest Draw on the equator and 5’N and 5’ lines of latitude Give your map a title and stick into your book Copy out the 2 correct statements from Q2

7 Equatorial climate world locations
Amazon Basin 5°N 5°S Equator 0° It is mainly found between latitudes 5°N and 5°S of the Equator It is found in the Amazon basin in South America and in the Congo basin in Africa

8 Climate graphs Climate graphs are a way of showing how temperature and precipitation vary throughout the year for a particular place.

9 Why does it rain so much in the rainforest?

10 Convectional rain

11 Rainforest climate and weather
Rainfall (in mm) Temperature in ‘C Jan 240 27 Feb 230 26 Mar 265 Apr 215 May 170 Jun 85 Jul 75 Aug 40 28 Sep 50 Oct 100 29 Nov 140 Dec 190 Complete the climate graph using this data Answer Q 1 underneath your graph Annotate the graph with your answers to Q3 and 4a

12 Equatorial Climate graph
Temperature in July = ____°C Temperature in January = ____°C It is hot all year round in the Amazon because the s____ is overhead t________ the year. This gives high t___________ and is responsible for the c____________ rainfall ____ mm of rain falls in a year The equatorial climate is (hot/warm) and (dry/wet) all year. Rainfall is (heavy/light) and falls during most (morning/afternoons). The weather for each day of the year is very (different/similar)

13 3, 2, 1 3 Pieces of information you have learnt today
2 things to revise 1 question you have

14 Rainforest trees - adapted to their natural environment
Trees grow very tall and straight… Drip leaves… Few branches… Plants near forest floor have large leaves… Buttress roots…

15 Rainforest trees - adapted to their natural environment
Trees grow very tall and straight… to reach the light as quickly as possible Drip leaves… heavy rain can run off leaves easily Few branches… due to the lack of light in the lower forest Plants near forest floor have large leaves… to catch as much light as possible Buttress roots… give trees stability in shallow soil, and a store of nutrients

16 Rainforests – true or false?
F - 28°C F – pm 1 The natural vegetation of all the land on the equator is rainforest 2 The rainforests contain examples of over ½ the world’s species of plants and animals 3 The climate of rainforests can be described as ‘hot, wet and humid all year’ 4 Temperatures fall rapidly at night time 5 The average temperature all year is above 35°C 6 Rainforests have about 750mm of rain a year 7 It rains every day at around 10 a.m. 8 The main rainfall type is convectional rainfall 9 Rainforest soils tend to be poor and infertile 10 There are 4 distinct layers of vegetation in the rainforest ecosystem
