Coniferous forests

The last geography lesson was on coniferous forest. We learnt that these forests are much more different than the tropical rainforest and tropical monsoon rainforest we learnt about earlier. To begin with the forest are found mainly in places that experience a cool temperate climate, usually around 60 to 70 degrees north and south of the equator. The structure of the forest is very different from the tropical rainforest as in only has one layer and all the trees in the forest grow tall and uniform in height, around 20 to 30 metres. The diversity of the plants is also quite lowa s not many plants that can adapt to the temperatures and precipitation of that kind of climate. The density of the forest is low. As for the leaves, most of the trees have needle like leaves and are evergreen as the leaves need tp be ready for photosynthesis the moment the temperature reaches above 6 degrees celcius. The main flower the trees bear are cones, hence the name coniferous forest. The seeds can be dispersed by wind or by animals. The trees bark and branches are thick and help protect them from the harsh conditions of the winters and they have flexible branches to let the snow slide of them.

Reflection on article

Hi, I missed the last geography lesson so I am not so sure what was taught during the lesson. However I do Know it was about mangroves and I recieved the article on mangroves so heres my reflection on it.

I think the article was very meaningful as nowadays not many people appreciate the natural wonders of the world esspecially in Singapore. I had a small personal connection to this article because when i was very young my father used to take my brothers and I to the Pasir Ris mangrove swamps and I always was very excited when we went. I personally think mangroves are very nice and peaceful, although it is true that it is dirty and muddy and has insects to a certain extent, it is all part of nature and I think everyone should try to appreciate natural vegetations and forest such as this. I like how the family in the article did not appreciate the mangrove at first but ended up loving their experience. I think whenever you have the opportunity you should definately visit a mangrove as they are going to dissapear soon enough.

In conclusion I think mangroves are not only helpful to the enviroment, in that they help to prevent soil errosion and pollution in the waters, but they are also beautiful and very few so appreciate them while you can.
