              Albert Lin is an archeologist (راثآ    ملاع) that thinks of how to explore the
              archeological sites without digging (drilling). There are different types of
              technology that enable archeologists to explore (where to dig and what they will
              find). These tools divided into underground tools and aboveground tools.
              Here are some tools archeologists used to explore the earth:


              1-The Ground Penetrating Radar (GPR)  ضرمأا          رادارلا زاهج  : is a way to find the

              buried objects under the ground.












              2-The Global Positioning System (GPS)  مىلاعلا عقوملا ديدحت ماظن: : is a way to find
              the location  of something using satellites.














              3-The Magnetometer  ةيسيطانغملا سا       يقم  : is a device to find the metal under the
              ground.
