Earth's Structure

Earth Science is the study of the Earth and its neighbours in space. It is an exciting science with many interesting and practical applications. Some Earth scientists use their knowledge of the Earth to locate and develop energy and mineral resources.  Many different sciences are used to learn about the Earth; however, the four basic areas of Earth science study are: geology, meteorology, oceanography, and astronomy. Today we live in a time when the Earth and its inhabitants face many challenges. Our climate is changing, and that change is being caused by human activity. Earth scientists recognized this problem and will play a key role in efforts to resolve it. We are also challenged to: develop new sources of energy that will have minimal impact on climate; locate new sources of metals and other mineral resources as known sources are depleted; and, determine how Earth's increasing population can live and avoid serious threats such as volcanic activity, earthquakes, landslides, floods and more. These are just a few of the problems where solutions depend upon a deep understanding of Earth science.

These Questions are nicely crafted with solutions to help you gain mastery over the content. Practice these questions once then again and again and again to gain a strong grip on everything that could be asked in the exam. Hope that you will enjoy this course in the long run of your preparations.
