Essays on Precession

Global warming is the excess greenhouse effect caused by various factors that rise earth’s temperature beyond an optimum level, causing adverse impacts to the biosphere. Earth’s temperature is determined by the amount of solar radiation received from sun, radiation reflected or absorbed by various gases in the atmosphere as well as various surface features such as snow, water bodies, built environment etc. (US Environmental Protection Agency, 2016). Natural as well as anthropogenic factors contribute to global warming and associated climate change.

Natural Vs. Anthropogenic Causes of Climate Change

Global surface temperature increases occur due to natural causes such as sunspots and Milankovitch cycles. Milankovitch ...

1) What is the importance of Geodesy for Surveying? Why do you think that Geomatics

Should students know about Geodesy? Discuss

Geology enables the determination of the alignment of land, including the position, territories, portion and shape through the application of theodolites, land data systems or other geodetic survey tools. Also, it is through geology that resulted in the creation of the GPS (Geo Information Satellite) systems which as a result has resulted in the optimal exploration of space and regionally associated information. Besides, geodesy for surveying, aids in the assessing the quality of control information to regulate the necessity for extra survey information for ...

Introduction

Seasons are caused by tilting of the earth around its navigational plane known as the orbit around the sun. Climate change involves the northern hemisphere and the southern hemisphere. When the earth is in the Southern and Northern hemisphere means that the season is at summer. Changes in the tilt of the earth lead to changes in the severity of the seasons, for example when there is more tilt leads to more severe seasons including warmer summers and colder winter and when the tilt ...
