Notes:
The Andes Mountains in South America, are the longest mountain chain in the world. Mt. Aconcagua is the highest peak in the Andes.

Notes:
The Loess plateau in China is also known as the ‘Huangtu Plateau’. It is famous for highly erodible soil on the Earth.

Notes:
The Stelvio Pass is a mountain pass in northern Italy. It is at an elevation of 2757 metres above sea level. It is the highest paved mountain pass in the Eastern Alps.

Notes:
Mount Tambora also known as Tomboro is an active strato-volcano in Indonesia. Tambora’s 1815 eruption was the largest in recorded human history and the largest of the Holocene.

Notes:
Erta Ale is a active basaltic shield volcano in the Afar region of northeastern Ethiopia. It is the most active volcano in Ethiopia.

Notes:
The Ozone lies at an altitude between 30 km and 60 km from the earth’s surface. It spans the stratosphere and lower mesosphere. This layer reflects the harmful ultraviolet radiation. The Ozone layer or the ozonosphere is also called chemosphere because a lot of chemical activity takes place here. The temperature rises at a rate of 5°C per kilometer through this layer.

Notes:
The proportion of insolation that is reflected back by the surface is called its albedo. It depends upon the nature of the surface upon which the solar radiation is incident and the angle of incidence of the solar beam. The albedo for the earth as a whole is called the planetary albedo and it is 35%.

Notes:
The westerlies are permanent winds which originate from sub tropical high pressure belt and move towards subpolar
low pressure belt. They prevail between 35° to 60 ° latitudes. They are more intense during winters. They transport warm and moist air toward the pole. The British type of climate or the western European type of climate is produced by the westerly which causes rainfall throughout the year. They are known as roaring forties along 40°S, furious fifties along 50°S and shrieking sixties along 60°S.

Notes:
Costa Rica and Nicaragua are the two nations involved in the San Juan River Border Dispute. This dispute arises in the interpretation of delimitation and navigation rights on the San Juan River, as per the Canas-Jerez Treaty of 1858. The 2010 Dispute regarding the dredging of San Juan River was called by the media as Google Maps War. San Juan River flows from Lake Nicaragua into the San Juan Lagoon on the Caribbean Sea. A large section of the border between Nicaragua and Costa Rica runs on the south bank of the San Juan River. The San Juan River is home to freshwater bull sharks.

Notes:
The Surface Zone is also called as the Photic zone or the Euphoric Zone. It contains about 2 percent of the total volume of water in the ocean. It is limited to a depth of about 100 meters.
Thermocline: It lies between 100 metres and 1000 metres. It contains about 18 percent of the total volume of water in the ocean.
Deep Zone: This zone lies below 1000 metres in the mid-latitudes. This zone contains about 80 percent of the total volume of water in the ocean.
