Rainforests
What?•A rainforest can be described as a ‘dense jungle’ and by dense, meaning ‘wet’.• There are two different types of Rainforests: Tropical Rainforests and Temperate Rainforests, tropical rainforests being tropical and temperate having temperate weather.
Who?•Numerous amounts of flora and fauna can be found in a rainforest• The Flora and Fauna depend on the layer of the forest ie. Canopy- birds, Understorey-jaguars, forest floor-fungi.
Where?•temperate rainforests would be in temperate regions ie. North America•tropical would be near the equator.
Why?•Rainforests get a lot of rainfall (1750-2000mm) •They cover about 6% of the world yet they have more than half the world’s animal and plant species.
Mountains
Who?•Many animals live on mountainous plains for example: Lynx, mountain goats, mountain lions, yaks, pumas etc. •As well as a number on animals, there are also trees and shrubs that grow on mountains.
What?•Mountains are higher and steeper than hills. •They are elevations of the earth that rise over than 600 metres. •Mountainous features include a slope and a summit.
Where?•Mountains are formed when the earth’s tectonic plates crash into each other, pushing the earth up and forming mountains•mountains would be found around plate boundaries.
Why?•Mountains cannot only be found on earth but actually can be found underneath in the sea. •Mountains also take up one fifth of the world’s landscape and 80% of our fresh water originate from mountains.
