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

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

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

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

Why does it rain so much in the rainforest?

Convectional rain

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)

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…

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
