Introduction In this essay we are looking at the four spheres of the earth in relation to population and everyday life of two chosen countries. The two countries chosen will be Niger and Slovakia which have very different sphere characteristic. Hydrosphere ,biosphere, lithosphere, and atmosphere are the main focus of comparison. The main differences relate to humidity, temperature, and soil fertility. The issues presented in each country, which is affecting the population and quality of life, can be linked back to atmosphere and the amount of water in the water cycles. In this paper we will explore health of each sphere and how they can affect the other spheres. Slovakia has a much better geographic location for its population and has …show more content…
There biggest market is agriculture, farming crops for food, and raising livestock in the drier regions. Like previously mentioned the lack of precipitation makes the coverage of vegetation limited and crops are unable to grow in most areas. In the Sahel regions Niger grows little rice and mainly tradition grains. (Our Africa, 2016). The biodiversity of the countries in Africa vary from the more wet areas having a high diversity and the dry countries having very little diversity. The dominate desert areas of Niger has a very low biodiversity but the Niger Delta has a much higher biodiversity (Collins N C Ugochukwu and Jürgen Ertel, 2008). Plant and animal diversity in Niger is a lot less than in other african countries, and a lot less diverse than Slovakia (S. N. Stuart, Richard J. Adams, Martin Jenkins, 1990). In Slovakia the vegetation consists of mainly grasslands and the forests take up two thirds of the country. The nutrient rich grounds and consistent water cycle help the biosphere thrive with diversity. The forest destruction was increasing until Slovakia decided to make protected forest areas. When the socioeconomics in Eastern Europe started changing there was more laws and regulations to help keep their forests safe (Tobias Kuemmerle, Patrick Hostert, Volker C. Radeloff, Kajetan Perzanowski and Ivan Kruhlov, 2007). The biodiversity in the steppe-like …show more content…
The hydrosphere and atmosphere are the main reasons that Niger has a lack of fertile soil while Slovakia is thriving with rich soil covering most of the area. Niger’s land area is mostly covered in sand dominated soil. The extreme heat evaporates most of the moisture and water in the soil and lack of rainfall means the nutrients the water cycle would give the soil is less than needed. Farmers use livestock manure to make the soil more fertile for there crops. (Kanako Suzuki , Ryoichi Matsunaga, Keiichi Hayashi, Naruo Matsumoto, Ramadjita Tabo, Satoshi Tobita, Kensuke Okada, 2012). Slovakia’s soil has a lot of stored energy. This energy is beneficial to the flora and fauna of the country. The main sources of energy that the soil receives comes from the sun and decomposing matter. Because the vegetation in Slovakia is very dense there is a moderate amount of decomposing matter to give nutrients and energy to the soil. This makes the soil more fertile and Slovakia can then grow profitable plants as they do. Slovakia has mostly loamy and silty soils which store the most energy unlike the sandy soils found in Niger (Jozef Vilcek, 2011). Niger has a mountain region, Air mountains, in the Sahara but it is nothing compared to the mountains in Slovakia. The Tatras region and other mountainous regions are very important to the lithosphere of Slovakia. Slovakia gets a lot of tourism
