<u>Physical geography</u> is the study of the natural features, processes and patterns that occur on the Earth's surface.
Nations of the world can work together to use energy more efficiently.
Bangladesh was formerly known as Eastern Pakistan. It was originally a region of Pakistan, but tax disputes and political autonomy issues happened. This caused Eastern Pakistan to join the Indian Military to fight against the Western Pakistan, and it eventually became Bangladesh in 1971.
The energy that the Earth receives from the Sun is the basic cause of our changing weather. Solar heat warms the huge air masses that comprise large and small weather systems. The day-night and summer-winter cycles in the weather have obvious causes and effects. The Earth's climate system depends entirely on the Sun for its energy. Solar radiation warms the atmosphere and is fundamental to atmospheric composition, while the distribution of solar heating across the planet produces global wind patterns and contributes to the formation of clouds, storms, and rainfall.
hope this helps!! :)
