Rainforests are a very unique ecosystem. They rely on 3 main things to continue to function. These are heat, moisture and nutrients. There are 2 main types of rainforests tropical and temperate. Tropical rainforests are found between the tropics of cancer and Capricorn. Temperate rainforests are much less dense and lie to the north and south of the tropics. Rainforests are predominantly found on the east of continents or on the windward side of mountains. Types of rainfall: There are 3 main types of rainfall: 1. Monsoonal (convectional) 2. Frontal rain ( cyclonic) 3. Orographic (relief)
4 layers in a rainforest: 1. The lower storey - This layer is characterised by being dark and humid. Little sunlight can reach this layer. Due to the large amount of rain in the areas where rainforests grow the ground is very moist. - Saprophytes, mosses and Lichen , small ferns 2. The middle storey - This layer is still dark as it is below the canopy, but is slightly less humid. It is also part of the rainforest that is most open. - Saplings or seedlings, tree ferns, vines or lianas, epiphytes 3. The upper storey - This layer has access to and controls the amount of sunlight the rainforest receives. It is the densest layer of the rainforest. - Canopy, Emergents
Rainforest Soils - Decaying Vegetation Humus - Thick black nutrient soil - Light nutrient poor soil as minerals are washed through - Soil containing large amounts of nutrients - Mostly small rocks and sand - Bed rock
We also have watched a video on the Huaorini Tribe who live in the Amazon and their land was destroyed by oil companies. We wrote notes on that and then wrote a creative storey about it.
In geogpraphy this week we have started relearining all our gepgraphy skills for our exams coming up! List week we went over how to read maps: GR 326 485 GRID REFERENCE 32.6 ACROSS THEN 48.5 DOWN
This week in Geograohy we have still been working n how to read a map and the grid refrences. We are working on skills and answering questions about a map that was handed out to us.We are working towards our exams in week 5.
