Blog # 4 Vegetation associated with climate changes.

        Vegetation is an important part of our life and has a hug impact on the earth. The climate changes affect our vegetation in many ways. There are many elements that a plants need in order to grow and they are divided into two groups: minerals and non-minerals. Climate changes make the earth more cooler, drier wetter and warmer and this shift the vegetation. In some cases like that, the land need to be on break for a certain time  for the people to be able to use it again for planting. Biography part that we started today, made more sense to me about how plants don't need us to survive. It is evident that we are a problem to the climate changes too.

This image show a vegetation landscape in Rwanda that has been affect by the climate changes. Because of the sun, the land became more arid and hard. The lack of trees leads to the soil degradation.

  In Rwanda, most of the population survive from fresh food straight from farms. Therefore, vegetation is more needed there in order for people to survive. In class we studied some forest where the land is covered by big trees that protect the ground from the sun. Climate changes has affected the vegetations sources. Things like water is a necessary element for plants and in some region, water has been rare. There also most plants that survive by water The more trees covers the land or vegetation, there is a shadow that protect the land from the sun. In class we went over the example of some plants that keeps water, some that don' need water to survive and those that need both water and the sun.

This is a plantation of tea. When the climate is favorable, people can even use the mountain for more foods.

This is an example of a fertile and green land. Some of the elements that make the land more fertile are animals like Cows, goats. I am not sure about the name in English may be it is called "mulch".

      

Storms and Precipitation in Rwanda.

          Rwanda's weather is massive because it is located in the ITCZ ( Intertropical Convergence Zone). The equatorial region is known as the inter tropical convergence Zone, because it is where winds from the Northern and southern hemispheres collide. Sometimes there are violent thunderstorms that disable airlines in flight because the thunderstorms can tower may be up to 60,000 feet: " said the professor Case during lectures,"  far higher than  the level the plane can fly over.In the equatorial zone, there are all kind of storms.

      This image shows how tropical cyclones cause vast flooding. Tornadoes are more violent and have a very very strong wind. Usually have violent rotating columns of air . They happen mostly after floods and lightning.

       

 This image shows a tree that been hitten by a wind. It's like microburst, when the wind goes all in one directions violently.

This image show how rainforests( in green) lie in the intertropical convergence zone where intense solar energy produces a convection zone of rising air that loses its moisture through frequent rainstorms.

Blog # 2 : Wheather in Equatorial Zone.

           The weather is due the earth revolving around the sun. During the 365 days, many climatic changes occur in all different zones of the globe. Weather is very important because it  breaks down all the minerals that we need to live. Most countries in Africa get hot very hot.There are rain, summer and winter seasons in Rwanda.

This is an image of inter-tropical convergence zone.
The phenomenology of the thunderstorms and the winds toward the equator.

This shows different down slopes of mountains or lands due to weathering.

Rwanda is like in 75 miles from the equator. it is near the equator, they receive a heavy rain daily during the afternoon due to hug evaporation. The rainy season make their agriculture manageable. There exist  types of clays that people use for bricks to build houses.  Due to many climate changes, Rwanda has some limited landscapes because of not enough water, some mass wasting areas and and some turning transport limited.

                                              

Due to weathering, we can see on this image how land forms drainage between between a vegetarian land.

        Variations in solar radiation, mountain-building, continental drift and changes in greenhouse gas concentrations, and minerals that we use in our daily life, it's easier to understand our weather changes.
