geophysical equipment are needed. These equipments are generally needed for easier understanding of the behavior of the earth and the environment. They have been around for several generations and have improved due to new software developments. The methods that were used earlier were different. This was due to the unavailability of modern and improved apparatus; this however did not interfere with geophysical activities such as geology and meteorology. One of the most common methods that have been used since the nineteen thirties is aerial photography. This technique is still being used but the devices and the cameras have been highly improved. This advancement has made the insight into the environmental changes much easier and more detailed. Infrared cameras have been used by scientists through satellites. The images that are taken by the highly advanced devices are used to study various aspects of the environment. The other equipment that has been used since the nineteen nineties is the gravimeter. This tool is used to determine the gravitational field of the earth. Through this study, scientists are able to determine various topographical features of the surface of planet as well as sedimentary thickness and how these features could affect environmental changes. With the new software development and advancement scientists have been able to come up with recent equipments known as ground penetrating radars. This device is used to mainly develop geological mapping. Concentrated wavelengths are sent into the ground and in case of any interference the information is sent back to the surface for recording. This geophysical equipment is used for the study of the earth and the environment. It is important to understand the changes that the earth maybe facing in order to ensure efficient planning. Technological advancement has made it much easier and almost thorough to undertake research and dynamics of the environment and the earth.">When studying the environment, various techniques and geophysical equipment are needed.
